I have seen way to many seats fall out from other shops over the years. I am always suspect of heads from other shops with new seats installed. Maybe they are alright but maybe they are not. Im not willing to take the chance :)

@dcimotorsports1111 Yep, don't take a chance.

Wow. Havent seen anyone stake a seat in a long time. Some old school stuff should stay in the past. 🤯

We actually did do just that and we thought we had found the problem.Of which was the multi layer steel head gaskets, but after all that it still is getting coolant in the oil and oil in the coolant. Which is really baffling, because I have seen one or the other, but never both. Here is a link to the video of us pressure testing the block of which it did hold pressure. th-cam.com/users/shortslNjIAvZuZY8 So now we are completely disassembling the engine and my next step is to plug all the coolant holes and put the block in an oven to bring it up to about 250 degree's Fahrenheit then pressurize it.

​​@@dcimotorsports1111 Yuck. Almost sounds like porosity in an oil galley to allow oil into the coolant? Sounds like you have a good plan. My buddy has a huge powder coating oven we have used to heat cycle new blocks before I have them machined. Not sure if it actually makes a difference but my brain thinks it does! Good luck. Hope to see a video where you have it all figured out.

​@@dcimotorsports1111Maybe try to pressurize the oil galleys when you pressure check it....might leak easier one way vs the other when cold?

The dry deck part is a definite,No alcohol though. This is going into a Protouring build and will be street and road raced. So need it to run on 93 :)

@@dcimotorsports1111 Is wet sleeved like A Cummins ISX and Detroit Diesel 60 ? Twisted Bottom O-rings during rebuilds were to be avoided or complete teardown again. High dollar Aluminum. Only way to find an internal Flaw hidden onna Block Is X-Ray it.

@@brracing7861 Its not a wet sleeve block and we hard blocked it up to the bottom of the freeze plug holes on the sides. So this one has me puzzled. Not to mention it doesn't start to pressurize the coolant system until it gets around 180 degree's.

@dcimotorsports1111 Tough Call Don. Maybe it back to those MLS gaskets again. Maybe hidden steam pockets are forming. Watched a guy made a video picking up his Steve Morris 540 Dart Block Full We5 cooling system 1000 Hp Pro Charged.Entry Drag and Drive. Steve O-ringed or he calls it his Hoops all 1 piece like Marty Rings we Knuw. Block had reciever grooves machined in. Heads machined groove, 2 slightly different diameters with a Copper Hesd gasket Annealed to his specs. I like my Factory Pontiac 455 iron blocks. When time Want an IA2, MR2 ,or yours. Weight penalty I dont care any. Next time on test stand cooling system filled with Zerex Diesel Antifreeze premix 50/50 filled, roll it outside your shop and leave it overnight. Midwest Illinois and Ohio Cold shows all cold water coolant leaks and Pressurized Hot Leaks too.

Same leak, now thinking we have a block issue :( Head gaskets are sealed, but coolant still getting in oil.

@dcimotorsports1111 Well, I know that you know what to do next, so, what I will say is good luck.

The speed calculator says around 270 HP for the MPH those cars ran back in the day. I do know the engines were capable though, because there were several stockers in NHRA trim that showed even a little more than 348 HP :)

Love it !!! Those were the good old days when us Pontiac enthusiast's didn't have good parts to work with. All we had was our brains and determination :)

Thank U Dave !!! Merry Christmas to you and your Family :)

@dcimotorsports1111 Thank you, sir!

These are actually RA4 round ports, but we do get way more than 250 out of D Ports too.

Awesome first car !!!! Hope to see you New Years Eve :)

I have had a Great Year !!! I agree our youtube lives are actually going in a direction I really hoped for. It seems like all the guys are conversing with one another as well as with Brandon & I which is AWESOME.

You are a true Pontiac die hard Glenn. You always have been :)

All Pontiac blocks from 1974 and older are pretty stout. So don't try and find a 421 or 428 if you already have a 400 block.

I forgot about that. Sad :(

Thank u Sir :)

But Dons start at $30,000

@@phillipthethird42 He knows I built him a RA5 about 2 years ago :) He had a lifter failure so he is waiting for me to get it back here to swap out the cam and lifters. Chinese strike again :(

@@dcimotorsports1111 I see.

That's our Street Strip Porting package and it starts at $1750.00 plus parts.

6800 if you're referring to the rev limiter.

Ha Ha That's because you are a wise man and follow us on our weekly Podcast :)

@dcimotorsports1111 ...and videos.

Ha Ha well I have tried to teach several through the years. Some can do it and some cannot :)

Thats A Fact :(

That starts at $1500.00 plus parts

@@dcimotorsports1111 Thanks Don.

Yes it is :(

Hi Robert, Thank U Sir for the KUDOS. This is an Allpontiac aluminum block. Tin Indian doesnt make a block for Pontiac's.

Thank U For the KUDOS :) I try to be as through as possible and provide a quality service and products. Now I want to share my 43 years of experience with anyone who is interested, so my knowledge is not lost after I'm gone. I'm only 63 so I'm not going anywhere soon LOL, but want to share while I can :)

Awesome !!! Happy for you Sir :)

Welcome and thanks for subscribing. Yes I know when I film with my phone whether I turn it side ways or not does this. I have asked a couple people with better tech skills than myself what I need to do which I have done, but it still does it. Its an older Note 8 so it might just be I need a new phone.

Thank U :) This is a pretty wicked 800 HP pump gas street build we do. :)

Watch this video here. We found our leak and whats causing it. ttps://th-cam.com/users/shorts6JB5Vi_LyBk
