Post Big Block Chevy

I just bought a 454 chevy from a salvage yard for dirt. It's out of a 77 1 Ton truck. It's complete with brackets, carb, manifolds, ect. Would this puppy have four bolt mains, being in a heavy duty truck application? I'm not too familiar with the big block casting numbers, but most 454s I've seen are 2 bolt main blocks with cast iron cranks. I'm pretty sure this engine will have the "peanut port" heads, but I thought it would be a great core to build upon.

It could have 2 or 4 bolt mains.A cast crank is a definate as far as I know.I htink it will have bigger oval port heads.Most Peanut heads were installed on 366 truck motors and very late 454's.It is a good core to build up for anything up to about 650 hp.Let us know what you want to do with it.I wouldnt sweat the 2 bolt maoins,I make over 1000 hp with mine.Good luck.

My uncle just bought a 454 out of a 1979 dually pickup.We ran all the #s it has peanut port heads and is a normal deck (not talldeck).I don't now much about bigblocks but I've heard that tall deck blocks arn't good for performance and require diferant dist and intakes.You can look your #s up at <a href="http://www.mortec.com" target="_blank">www.mortec.com</a> <a href="http://www.Mortec.com" target="_blank">www.Mortec.com</a>
