- I pulled the factory stock race engine out of our Crate Racing USA Street Stock Chassis and we are doing a full tear down. In this episode we are figuring out if this circle track race engine can be rebuilt again or not to be run in our leaf spring camaro driven by our new rookie racer Rachel!

Felpro 1003 is head gasket part number
Right, I think those are the rubberized 0.015" ones. Thanks
Very informative
Thank you Mr Bill
Another great video.
Thank you sir
I coat the steel shim with Permatex super 300, never had a problem.
I like the spray better. I agree, use something, never just the steel shim.
I run a limited modified. Our engines are pretty much the same engine rules as a factory stock besides the camshaft and a few other small things. I finally got my engine ready last week. I freshened up the rotating assembly, and installed a new hydraulic speedway camshaft.
I'm right behind you Mark on getting this one done as well. Can't be waiting until January for this stuff !
I’m just glad there’s guys still around like you man. Doing all the work himself!
Man I live for this part. I have just as much fun in the off season doing all the shop part :)
Awesome video! Glad you’re showing this part, this is the part that wins races!
Thanks Tyler, have a couple videos on this part and then we'll be working on getting the leafer ready.
Fun video to watch ! Thank you for sharing your experience . You either guard the information you've learned or share it. I decided since i was fortunate and had guys show me how or another way to do things , I would offer it to others . Looking forward to the next part in your video.
Thanks Barry, sounds like you and I are on the same page when it come to helping support our sport.
I though your camshaft would be bigger? Isky or Mike Jones!
not for this engine, i built this one to meet rules for vacuum and lift. She's been a rock solid performer with this cam for many years though!
I love the mechanical end of it watching your videos I get an urge to go back into racing because you make it look so easy but in reality I know different especially to build a car from the frame up that's what's nice about TH-cam it makes you feel like you're there doing it keep them coming
I appreciate you sticking with me all this time. I'm just showing it all how it really is and it seems to make for some good content for a growing audience. Thanks
A narrow ring package if you can run 'em will reduce you cyl wear...1.5mm 1.5mm 3mm..
Very true! On our new build we went with the Mahle pistons partially for this reason.
That little engine impressed me at whynot.
She's been a good one for sure Eddie but I'm pretty sure I can find quite a few more horses in the one I have getting machined now and that will really help me in the qualifying game :)
How many 4 bolt mains you need
Where were you last year!!!! LOL. I'm good now, putting it back in the Camaro now and hoping to start assembling my CRUSA engine for the coil car in a couple weeks.
Great video Jason
Thanks Jay
What kind and weight of oil?
I use Valvoline Vr1 in most of my engines (best priced high zinc racing oil I have available locally)
as far as weight, as long as I am in the 0.0025" to 0.0035" range on oil clearance I run 20w-50.
if I have an engine that is tighter on clearance I will drop that weight if I need to.
If you do find that it's done call your machine shop and talk with them! Sometimes thay have abandoned projects that they will sell for cheap!
Thats a good idea :)
Seriously need to ask that everytime I visit any machinist. Never know when an opportunity could knock!
My home track is allowing the Chevy LS 5.3, 5.7,6.0 engine stock . Whould you run a LS Engine?
In a Heart Beat! Bone stock with a stock tune it still is better than a crate 602 :)
Is this a 6 inch connecting rod?
no, this engine is legal for several restricted classes and I use a 5.7 Forged 5140 I beam rod in it.
Great job 👏 👍
Thanks Calvin, appreciate you watching :)
Hey I was curious do you run your welder on 110 or 220? I have same one and couldn't tell in your videos
220 at all times Doug. Heres where I am typically at on setup for mig on tubing work: I run 75/25 mix on my gas and use 0.035" wire. I usually stay around 200 inches a minute and from 17.8 to 18.2 on voltage (varying depending on tube thickness and conditions). I think I am running about 3 seconds of post flow as well and usually keep my flow rate down around 10 inches as long as the doors are closed but in the summer with a fan on I will turn it up at times if I am blowing my coverage off from air movement in the shop.
Hope this helps!
If you have to ridge ream it needs bored
I totally agree Jim. Speed pro pistons, cast crank, and 5140 rods in this block that was already 0.060" over means there wasn't much value there. I was either going to do one of two things: buy rings and bearings and open her up to about 4.063 or just scrap it all. In this case I felt it was worth it to let er eat for a couple more seasons. But make no mistake, we'll run her till she let's the smoke out this time because there is nothing left to get out of her after this 😉
Well then use a good hone and not ridge ream better a little big and straight top to bottom and round
Exactly. Sounds like we are on the same page.
I've always heard that its best to match up your intake specs with your cam specs. Is that a myth or does it really matter?
It is NOT a myth. When I consulted with Mike Jones and ordered a cam, he was very specific that I not use a victor series intake and instead change to the victor junior with a smaller port volume.
@@DIRTRACELIFE Awesome thanks so much. I was just wondering if I have been wasting time in the past lol
If the bolts are not stretched, do you think they'll be ok?
When it comes to stock head bolts I like to just grab new ones. I have no issue reusing ARP studs and bolts and I am doing that on my other build. Some people reuse stock bolts many times, I don't but if none of your old bolts show to be over stretched then it should be fine. But how do you know for sure none of the old bolts are over stretched. . . . I just don't risk it.
So just curious why do you replace oil pump, if the car is putting 70psi ? We are refreshing our engine the same way.
Call me paranoid but I feel like if I skip that $35 melling pump, Murphy's law will kick in and bite me dead on the tail. I have inspected and reused many many pumps but have just always replaced them in my race engines. Your right though, the old pump was mint.
Don't take much wear if you have great filling fingers and being very mindful of what you have to catch that wear in the block.
Boy its close and truthfully I cannot say 100% this block is good to go until we have honed, prepped, and measured all 8 cyclinders. Trying to get started on that this weekend and hope it goes well.
If your going to get a new carb for that car then get one from TCC carbs. I have run a few different carbs and I promise there’s night and day difference. Texas, Arkansas, Louisiana, Tennessee and Oklahoma cars I know love TCC carbs. Your racing against them and so was I and try not to follow the leader I try to beat them but after 6 different carbs I learned they already found the best one. Get a stage 2 if your rules allow it. Best of luck and can’t wait to see you in the front.
I am planning to purchase a new 4412 for my CRUSA car yeah I will check them out. Thanks for the tip.
Brandon Buhler at TCC is your man. Same person I use as well.
Brandon can definitely hook you up. I brought a carburetor to him a few years ago. It was well worth $500 getting it rebuilt and reconfigured.
Should be the Fel Pro 1094s brotha. Good gasket.
Dang, yep, my brain totally stalled on camera :)
Thanks for sharing this bud.
@@DIRTRACELIFE Happens to the best of that the sad reason I know this I’ve been into my motor 3 times this season unfortunately and just had a new one built because I was tired of it 😂. The 1094s are on it also. I race in south Ms Pike County Speedway or Jackson Speedway. Second season rookie still in my book. No wins yet in the one that counts couple top threes and plenty top 5s I like to say I’m a heat race hero with 7 wins this season 😂. Hope to run into you sometime and truly enjoy the channel.
Shoot, you are doing well bud. I'll be looking for you if I get down that way.
I like the engine stuff, keep up the videos! any reasoning for such a wide lobe separation on the camshaft? You rarely see circle track engines over a 107 108 LSA, I seen some people use wide LSA on heavy duration engines like 250 @50 and up on flat tappet but I was just curious your thinkin on it
Thanks for the feedback bud, the wide lobe separation is a feature you'll see often on cams that need to meet a vacuum rule. When I went with this cam I was running some classes where there was a 16" min vacuum at 1000 rpm rule. You're gona pull hard off the corner with a little wider separation but it dang sure hurts you up on the top end. It's all a balancing act :)
What’s the biggest build engines in crusa. Loving the content. Thanks
Legally its 362 inches. There are some guys running a 400 block and 3.35 stroke cranks to get that number. Makes for a wicked mean little motor.
Very Good Job. Cam bearings?? Do you always change them out regardless?? They are a pain in the butt to inspect.
Keep up the good work!
These are absolutely mint but Yes I have to inspect them before just keeping them. I use a snap gage to do it. I'll try to show that step in the next video.
A true 90%er video 👍
Hey, I learned from them west coast 90%ers ;)
You can run a solid lift cam now though; you aren’t going solid?
I have my new CRUSA engine block at the machinist having it decked but this little engine is going back in the leaf spring camaro for us to run in several different factory stock / pure stock classes around the region and some have cam/lift/vaccuum rules this cam will work well for :)
This engine is going back into His old Camaro for His Daughter Rachel to run in factory stock.
@@DIRTRACELIFE wasn’t talking about the CRUSA motor, this comment is for the factory stock motor. I know you ran a lot at Camden a lot so just letting it be known they changed the rules last year I believe where you don’t have to run a hydraulic cam anymore and still the 16” vacuum rule I believe. I figured all the local tracks was on the same rules as us. Just giving you a heads up before you put it back together; could free up some horses 🐎
@@DIRTRACELIFE I haven't ran a vacuum rule.
But I'd be interested to see what a 108 lca with less duration (same overlap) would do on the dyno (that is a standard stroke right? if 383 then 106). Probably could get a little more lift too if you can run a solid and a more agressive lobe.
My guess would be more power nearly everywhere in the usable rpm range, perhaps enough to matter but untested (know it works without a vacuum rule).
Can be a thing down the line after she gets seat time.
Modified rockers for pivot lube...
