but i dont want stock pistons i want to go high performance everything

EDIT
Also im wanting to be able to drive this car as an everday still so keep that in mind

you want to bore and stroke it and still use it as an everyday driver lol, i dunno about the 400, but a friend of mine made a 383 stroker for his truck, now it costs him $100 in gas to go 100 miles lol, with gas prices the way they are i'm happy with my 301 for now, i even put off putting in the 350 lol

the push rod thing sucks, i hate being forced to do work on my car, it's so much nicer when your doing it because you actually want to.

i dont mean im going to drive it everyday i just mean if i want to drive it on the road a lot that it want put anywhere and tear on the high performance parts.

Dude!

First things first. Get Jim Hand's book "How to Build Max-performance Pontiac V8s" by SA Designs. It's the latest study of the old Injun, and is quite accurate and CURRENT. It will answer most of your specific questions.

There are a couple of stroker kits on the market. We sell a lot of the Eagle. Makes a "461" out of a .030" over 400. Lots of info out there, some "good", some not so good...

There are also a couple of really good Pontiac-specific websites where you can get all the free info you need.

We have several of these (strokers) out there well over 600 horsepower on 93 octane fuel. Be warned, NOT cheap to build such a monster. If 500 is plenty, they're quite reasonable to build.

Lastly, ignore the buzzing in your ear about "Yo gotta use a Chevy. A Pontiac won't run and it will blow up..." NOT! One of our guys goes 10.50s all week on 93 octane in a true "street" '70 Firebird. Well over 3,000 lbs., it has made over 100 1/4 mile and nearly as many 1/8 mile passes, as well as Friday night trips to Dairy Queen... Still out there terrorizing ricers!
