What are the heads to look for and stay away from?
A good set would be 781 or 049
Alright thanks, all i really wanted to know!
Those are the large chamber ovel port heads.
The truth is.. 781 and 049's are the best large oval port heads because of the large intake runners. Those are good for upper rpm ranges.
Peanut Port BBC heads are just as good for "STREET" cars. These are good for bottom end torque.
I don't pass up any BBC head that isn't cracked.
This is going to be a side project motor for either my camaro or my dads bel air.. So we will see
I found another but he is unsure of size
I found one from like 1988 for 300 bucks would that be a good buy? It is in a dump truck is what the guy told me and i can hear it if i want. I do plan on going through it if i do buy it. Any suggestions on what to look for? How can i tell it is a 366(something i dont want)
If its in a dump truck its not a 454. It's most likely a 366 or a 427T
If its still in the truck look at the glove box lid, it should have a sticker there, if not, Check the casting numbers on the drivers side rear of block on the bell housing flange.
If you are planning on building up a stock 454 truck engine then a set of early closed chamber heads will bring the compression up. All the pre 69 heads flow as well as the 781's but have chambers that are about 20 cc smaller. Good for about a 1.5 point bump in compression. My favorite castings are the old 063 heads but there are many others
Stay away from the 236 castings, they are the large chamber peanut port heads common in the 80's.
