Hi again from México, just a simple question, what can be the highest performance for one block 455 (396021Fa). Are they good engines to run?

One good friend said to me: " you better get one 350 Chevrolet, or much better, a new car, a Nissan's car". But I'm not sure and I don't like Nissan.

I have the money to start the rebuilding of the engine, but I don't know if this engine can respond as I want (something like 0-60mph in 5s).

What do you thing?...

Sorry for my bad english.

Regards from México.

By the moment, this is my list of wins in street races:

1.- Dogde Ram '05 2500 whit HEMI 5.7
2.- Cadillac deVille '75 whit GM 500 8.5
3.- Volkswagen Bora '02 5cil whit 2.5
4.- Ford Focus '02 4cil whit 2.0
5.- Chevrolet Cheyenne '89
6.- Nissan Altima V6 '95
7.- Honda Civic V6 '03
8.- Mercury Grand Marquis '72
9.- Oldsmobile Cutlass Supreme '79

There is one 455 that is making about 890 horsepower, don't know how long it will live though.

This of course was a high dollar build, general consensus seems to be that the block is pretty safe up to about 600 HP, any more than that requires quite a few strength modifications.

It should be noted that I don't have experience with any of these types of builds, I am quoting what I have read and learned from Olds engine builders.
