Okay so a quick question, searching hasn't turned up an answer yet so hoping someone can help me out:
What's the difference between the exhaust ports on a TBI 350 head, a vortec 350 head, and an LT1 head?
I ask, because the car I'm trying to have driveable by the end of summer, a '93 Caddie FB, complete with camaro pedals and a 4 on the floor with a hurst t-handle, currently has a 350 TBI, high miles, still runs good but I'm going to want more power, stat.
So my planned engine upgrade is to get a fresh 350 block, fresh bottom end, lower compression & forged pistons (supercharger swap hopefully in the next year), vortec heads (already got em) and who knows what else.
Right now the car has manifolds w/a.i.r. bungs
that's gotta go. I would like to upgrade to headers before getting exhaust bent up so that I don't have to rebuild everything when I go from TBI heads to vortec heads. I'm curious if the LT1 ports/bolt holes are the same as either, as it's far easier to find headers (and a better selection no less) for a 94-96 impala/FWB with an LT1 than with a TBI 350.
Somebody help me....
