So as some of you may remember my 02 300ex build which can be google searched under that^ exact name.

But anyways here we go again, but this time I’m going for more power on the engine with a namura 330CC big bore kit, I already got a mid to high range ported and polished head, and I just finally ordered the 330 kit.

I started this thread to get some help, I have a manual, but what kinda things can I run into here?

It’s a 02, could I still run into case clearance issues, and I’m using the stock cam, and arms, but I got kibble white performance springs on the new head.

What kind of power increase am I looking at, and can someone point me in the right direction to start with main jet sizes? My current is 165 main, 42 slow.

Motor Mods:
FMF full exhaust
400ex carb
Uni filter with 8 half inch holes drilled in box.

Thanks,

Pics to fallow,
