i am looking into building a 427 small block. i currently have an edelbrock performer rpm cam kit, heads, intake, and carb. i am looking into putting that on the new motor. would a 427 small block be to radical for an everyday driver, and how much horsepower am i looking at having ? thanks for everything.

humm, dunno if your heads will breathe for the big motor...

Lets put it this way do you feel the rpm cam in your 355 is radical?

I'm gonna guess your answer would be no. Think about this, a cam will seem smaller (less radical) in a larger cubic inch engine vs a smaller cubic inch engine, even if the cam specs are the same.

I agree with killerformula, you would be giving up potential hp and tq with the edelbrocks, with that said, it should make a nice torquey motor to motivate your heavy monte carlo.

If thats all the budget allows then go for it, the cubic inches will be there if you decide to go with larger port/ higher flowing heads in the future, who knows it may keep you satisfed for a while, no guarantees though, this hobby can be addictive. Sounds like an interesting project, good luck

Is that a small base cam to fit the 4" stroke ?
I drive my 427 all over the place without any problem.
You may want to re-think about using those Edelbroke parts.
What type of block are you going to use ?

Did you use the World Motown block?
and what rotating assy did you use?

[killerformula]

he used a GM block

Just build a bb 427. More torque, less money.
Or just stay with a 400 sb and use the parts you have.
The perf/rpm package will not work well in a 427 sb and I doubt the cam will work at all. You will more than likely have to go to small base circle cam.
