Will a TPI fit with a HEI distributor?

 

yes

 

You mean the ld style HEI with the coil in cap? I don't think you would clear the extension off of the plenum. That style HEI has a pretty tall cap. IF you don't mind deleting the extension, I think it would fit...

 

Yes, it will fit just fine. The 85 and 86 cars came from the factory with the coil in cap HEI.

 

It'll fit, as long as were talking about the early TPI coil-in-cap distributor. I ran one on my 305 TPI for a couple years. It should fit with a factory coil, but won't clear if you use a Supercoil, you'll need an aluminum cut-off plenum extension. Bought it from Jeg's for $18 2 years ago. Made specifically to clear Supercoils. I have 3 of the damn things in my garage. This 'large cap' is the coil-in-cap HEI distributor, right? The only problem I forsee is the connector...it changed around '86, so make sure it'll fit...

 

Well here's the deal I'm gonna put tpi on my 67 camaro and I got the early style non-computer controlled HEI with the coil in the cap. I'm using an Accel brute thunder coil that fits stock unlike the supercoil that's taller. So I guess it'll fit.
Just FYI I'm going with an SDS computer that just does fuel management.

Any tips anyone could give would be great
Thanks
