Swapping from TPI 305 to L98

Is it worth it? Would my current TPI intake and stuff bolt right on?

Need more info.


There is no difference between a 305 TPI system and a 350 TPI system. They're identical.

Re: Swapping from TPI 305 to L98

The 305 TPI has smaller injectors, I think they are 19's?? While the L98 has 22's. I would get a bigger cam and better heads. But that’s just me and I didn’t do that on my rebuild I just got a bigger cam...
