350 tpi
i just picked up a 87 iroc 350 tpi.
i have heard that the tpi setup between 305s and 350s are the same and this causes the 350s to not have as much power as they can.
is this true?
and if it is would bigger injectors fix it?

Re: 350 tpi
Correct on the Injector Difference
also the 350 eprom has much better settings
if you add the normal performance parts Exhaust, Headers, tune, gears
the 350 will produce!!! much better results

Dumping more fuel in by putting bigger injectors will do little except hit your wallet
