The TPI will work....

The only thing is that you will have to chip the computer to be fully compatable....

Also to get the full potential if that tuned port came off a 305 and your putting on a 350 I strongly suggest putting the 350 sized injectors in it....Off the top of my head I think the 305 came with 31lb.hr. inj. while the 350 had 36lb.hr. injectors....

I would call JetChip on the computer issues www.jetchip.com and for a simple instalation harness call Painless Wiring.

good choice.....my two favorite things in life....TPI and 66 chevelles
