Got a friend with a 455 "rocket" motor.. I know the thing is gunna need rebuilding, being pretty damn old.. He's asking like 300 for it, complete.. I think it's got around 75,000 miles on it, and the outside is really rusty.. Would take a LOT of work to get it in good condition again but the heads and block aren't cracked or warped.. Anyone think it would be worth it? Anyone even know where I would look for cams and rotating assemblies for that thing? Even gaskets?

 

Jegs and sumit. all it is is a 454 with a bigger bore. 454 parts sould work just fine in it but i could be wrong... Jeremy should know

 

The 455 rocket is an olds motor, so none of the 454 BB parts would work, at least the biggies like heads/cam either manifolds. Ive seen a set of heads and a few cams for the motor in jegs but Im sure there is a place with better selection.

 

The down side to building an Olds engine is cost of aftermarket parts. Mondello performance specializes in Oldsmobile aftermarket performance, but they are expensive. Another down fall is that there aren't many knowledgable engine builders that do Olds engines. It would be a serious pain to try to get that engine into a thirdgen being that its much wider than a small block chevy.

 

if the 455 is the same between BOP, there's a guy on here, ponchoTA or something to that effect, who seems to know alot about 455's and puttin'em in our cars

 

As the other guys said, it's an Olds engine and the only way you can interchange 454 parts into a 455 is if you do a LOT of machine work on the 455... I don't have any questions about putting it in, I just wanted to know if there is a big market for these parts, cuz if not I can expect to pay an arm and a leg.. Guess I'll just have to do some searching

 

You'd end up paying out of your a$$ to build an olds motor. No parts from a 454 chevy bb will fit, it's totally different and you won't even machine 'em to get 'em to work. What kind of car is this going in? You'd be better off building a mild bb chevy and putting it in there. Nowadays you can fit anything in anywhere And you'd have a killer ride with a bb in it

 

Seen Buick 455, a lind one at that and it runs 12.20's in a believe a 86 or 87 TA at the Nats every yr i go :-) lots of fun :-) Those are wide as the Olds engines basically, so if it fits u could make an Olds 455 fit to without going crazy........


Sides and weenie can build a chevy real men are different :-)

And all Olds engines are "rocket" they all use the same architecture from the 307 to the 455 (330 and 400 have 39 degree valvetrain though kinda oddballs)...the larger engines just have basically a taller deck, the heads and stuff can be made tow rok from one to the other within reason just like a pontiac engine

Hmm.. I know the 455s are generally torque motors but 12's are a little high for what I'm wanting.. It's ok though I don't think I'm going to bother with all that rebuilding on an old motor.. If I'm going to do any building might as well be new.
