I love the trash bag idea, I’m sure many people will give their inexperienced opinions about your going to blow your engine or it’s bored to big lol or it’s the sharp edges will start glowing and detonate. Maybe with a high boost turbo or blower with extreme cylinder pressure, but sounds so good and thanks for the video. Y’all did amazing job on this build, Nothing like a small cid ford engine at high rpm’s.
Steve Morris said when he was in pro-stock they could get by with 0 valve to piston clearance. A lot of deflection indeed. Thanks for the video. Well done.
Motor sounds great i really like how much you raised the runners in the head , i wish you the best of luck and i am anxious to see how you make out with this engine, ill be watching for future videos
Been there done that more times than I could care to count lol, very time consuming but keep at it, I bet it will sound nasty at idle, I love the little hi -rpm engines
Excellent insight- In regards to the oil pan volume did you suffer from starvation with less than 10quarts ? I'm running 8.5 quarts to 9600rpm - we worked on getting the return back more effectively- 72psi oil pressure 5W- 30 in a 303ci V8- Cheers
@@shawsgarage3635 Never perfect 😉- we just but a box around the pick up and funnelled the rear and front drains close to the pickup box- this occurred after the enclosing of the cam tunnel- which by the looks of it was holding up the returning oil- Good luck with the racing
Are you running the truck at Mooresville drag strip this weekend im planning on being a spectator this weekend i enjoy when the gassers show up at shady side
Love the Boss 302, but how is it legal for SEGA's 1967 year cap? Love the exhaust plate mod, NASCAR inspired and adopted by Roush and Glidden, etc.!! Good luck with it!!
@@shawsgarage3635 I looked at the rulebook and did see them listed. I love watching SEGA events, and I appreciate variety. If they'd let me run an automatic (62-up Powerglide), I'd build a Opel Kadett wagon gasser with a 430 Buick, just for fun. A G-Force and clutch would cost more than the rest of the car with a 'Glide, so... lol
These pistons have too many of sharp edges for me. Id be tempted to get the Dremel after them and round the edges a bit more, and possibly take days getting them equal , then deck the block about .020" checking first..
@@jamest.5001 it’s hard to tell from the video but I went over all the edges with a dremel tool and a sanding roll. Block is already decked .025. The engine made killer numbers on the Dyno and when we get it to the track this weekend, it will either go or blow. That’s racing.
Use to spray factory roller bottom end blocks up to 400shot with a progressive system, crank never broke, but did eventually crack all the main caps!!!
, I beg to differ on that crankshaft, if it’s the original crankshaft from that era then it probably stouter than most aftermarket models of today,, I have a 1969 351w that I stroked,, if I could have found or gotten the original crankshaft that was in it from the factory I would have never stroked it but the people I bought the block from didn’t have it, it was just a block with the main caps😒
ok so you made 550 -575 horsepower with a 302 n/a. not really a barn burner. but that's about the limit for that set up. a smaller cam is gonna give you more torque... .700 lift is too much with those heavy rods, imo.
I told you that you couldn’t tell from looking at the screen . It makes 705 hp and 460ft/lbs torque. You can’t be competitive in SEGA without making at least 2.2hp/Ci
@@shawsgarage3635 so depending on your weight class, 2200 lb car, i expect to see your et at 8.51/160 trap, 2400 lb 8.76/ 155, or 2800 lb car, 9.22/147 trap. let's see your time slips. i don't think you have the torque or hp to pull it off.
@@axlegrind4212 we are 1/8 mile, 3130 lbs. this should run 6.10’s . We’ve been 6.18 110 with less motor than this. Record in our class is 5.99 with a 306 Windsor.
That engine won't Last with roller cam and Bronze valve guides and if its bored over 30 thousands it will leak anti freeze into the cylinders walls nothing like original ford parts from the 1970 s
@@jeffreydurham5342 I’ve ran.060 over on many stock roller 5.0 blocks, sprayed a lot of big kits on them, never cracked a cylinder wall. Sure blown a few head gaskets, but that’s common on stock roller 302 blocks with only 10 head bolts, always had good luck with O’rings put in the block decks though. 👍

That is an exotic, tedious, and powerful build. Great job, and best of luck racing it!

Where is your shop & do you work on 4v Head's.
Great video.
Thanks for posting this, you obviously know what you're doing. Don't let the armchair experts get to you. Good luck racing and be safe!

subscribed. very interesting vid.
Was it ran with a vacuum pump? If not, you ever tried one? May be worth some at that rpm especially.
@@JohnThomas-vb9se no. Our rules do not allow vacuum pumps, only evac tubes.

These heads were in development with Ford in 67 so SEGA has always allowed them. That was decided before I started racing with SEGA.

What kind of specs does the camshaft have to turn this much RPM
271, 283 duration 775 lift 112 lobe separation
The original crank is 1010 steel wont last long. 😬 Eagle Molnar or Scat much better.
You may be correct and it may fail tomorrow, but you would be amazed at how many 9000 rpm passes this crank has made. Thanks for watching!

It’s a Dart block. It’s already 4.130 bore. They can go 4.185.
Hilda, these are like 1776 with M4s instead of muskets. None of this stuff was around in 1967... tunnel rams came out in March, 1968, for example.
Why will .030 over leak antifreeze in the cylinder??? I’m just curious how you came up with that!!!
