well the 301 in a 3600lb empty car is a joke! they make what.... 145hp off the showroom floor.
going to a 455 is a bit of work. 400 is alot easier and cheaper! |

samson just get a 400 and put an 4.21 eagle crank forged rods and pistons in it, if you bore it .030 over its a stock bore 455. You can even do it with stock rods and stock pistons, but I recomend using forged rods, its not that much more $$.

Actually, I believe the stock 455 bore is .031 over the standard 400 bore.Kind of hard to find places that have standard bore 455 forged pistons.Most carry .030 and .060 over only which would be .061 or .091 over for the 400.

Pistons are still available for standard bore 455's. Last time I checked a 400 had a 4.125 bore and a 455 had a 4.155 bore. Of course you need room for piston expansion and such so bore dia. will vary somewhat.
How much power it makes is dependent on the heads and cam. A larger engine will make power lower and more of it, than a smaller engine. Its somewhat easy to get 500hp at the crank with a 455, and 400hp is easy with nearly stock parts. First thing you need to do is figure out a budget of how much you can spend on it, then how much power you want. Learn as much as you can about the engine you are building, and get opinions from people who know what they are talking about. Me I am clueless, I know less and less each day...lol. I need to forget all that chevy crap that doesnt apply.... |
