ive got a 70 mm throttle body off a 304 sitting in my cupboard and I have been told 8 and 6 cyl is interchangeable so will the 70mm throttle body work on a supercharged 6cyl?

Won't fit, the 304 TB's are interchangeable with the older 3800 V6 (Buick engines) but the Ecotec/L67 engines are different.

Best bet would be to get either a 70mm or LS1 TB and adaptor from MACE to suit as suggested above.

You need to be aware that upgrading to a larger TB is not going to be as easy as bolting it on. All your auto's shift points will bee out of whack and need to be touched up to get the car to drive correctly.

Yeah, but that's half the fun of "self discovery" when doing engine modifications :hmmm:

Seeing as the surprise has been ruined, MACE can supply a tune to suit enlarged TB's.

I have an LS1 MAF on the Bomber. Needs Retune to be effective.
