I'm in the US, and have built a few 302s. If you need help locating parts or coming up with a combo that will rip the treads off the tyres, let me know.

Just out of curiosity, have you considered going Fuel Injection?

A carb intake manifold can be modified to run fuel rails and injectors by your local machine shop.

I'd suggest going twin T3 series turbos, single intercooler with dual inlet, single outlet.

As for the 302s cracking at 500 hp. I've seen one crack in two, right down the middle, at over 950. But it was a high compression supercharged engine sprayed with Nitrous.

If you run the correct Compression Ratio, forged pistons, forged rods, forged crank, you can run 750 hp all day. Just as long as you set the AF ratio correctly.

To the guy who said turbos have too much lagg, not enough torque, eats fuel too fast, etc...... you were using the wrong turbo.

For a little history on me, I joined the board to research the possibility of using a Sierra Cosworth Turbo cyl head one of my cars, a Ford 2.3L powered mustang. just so you don't all get ticked at me for jumping into the middle of a thread and throwing some BS. I have experience with 302s, so can help.
