GEN VI 454 build

Looking to build a 454 and was wondering where would be the best place to buy all the stuff I will need for a GEN VI block? Im also considering stroking it since Im going to buy a new crank. Any thoughts are great!!

You can get a 1 piece rear main seal kit from Eagle. They stroke well with no block clearancing most of the time. Even at that, an adapter will allow a 2 piece rear seal crank to go right in. not a cheezy mod, it works great.

Other than that. The cam timing cover and oil pan are the only thing that will need to be Gen VI specific. Any generation cylinder head will work.

I've done tons of them.

As far as I know, nothing is wrong with a 1 piece seal...and it's actually better than a one piece. I've never heard of a 1 piece seal leaking, but I've personally seen several 2 piece seals leaking, and leaking pretty badly. I think the reason he says to do the convert is that most bbc cranks are of the 2 piece variety and it might be cheaper doing the conversion rather than forking out gobs of money for a custom build 1 piece. But I'm only hypothisizing here.

That's kind of what I figured. I just didn't know if he knew what the difference was between a once piece and two piece rear main seal.

I have noticed the variety isnt as large for the 1 piece cranks. I already checked with Summit and Jegs and they dont have a very large supply of BBC GEN 6 stuff.

Your right 35Window...

Gen VI bbc motors are 96 and up. You can find a great listing of chevy block casting years here...this one is big block specific...

http://www.mortec.com/bbc.htm

www.mortec.com is the base site.

Also, the reason you don't find many 1 piece rear main seals is because the blocks are newer...in most cases, 1987 and newer I believe. So there just isn't as much call for them as of yet.

It depends on if you want to buy a balancer and flywheel also.

Go internal if buying everything.
