I'm looking for a used set of chevy tpi runners to fit an 87 Z28. The big tube type like tpis makes.

dont bother with factory heads
you can do other things cheaper=port the plenumn
or more benificial= base manifold
the factory runners will out flow factory heads by alot

be even better to ditch the whole factory design and get the holley stealth ram i think its called or spent alot of $$$$ on tpis mini ram

I already have a tpis bigmouth intake, & when I pulled the plenum to install the adjustable fuel pressure reg, I ported the plenem. You were right in one of your posts there is Shocked

alot of extra crap in there. it's all gone by by now. the Z28 pulls alot harder Twisted Evil

from 2500- 4000 or so. all the new goodies will go in soon when I pull the drive train out of the bent 87 Z28 To put it into a straight 87 RS body. the 305 will get freshend up also. I'll more than likely attack the heads with my die grinders too. I've got a guide on porting these heads. Twisted Evil
