Crate Engine Question

I am looking at some 350 crate engines. I was looking at some short blocks. Why do some of them say for Carb only?

For emissions reasons.

So it has nothing to do with the way engine runs? Can it actually work with a TPI setup?

Yes. It really depends upon which heads are used. The TPI intakes center bolts are at a different angle than the earlier heads.

Yes. Or you can use any heads you want and just elongate the center bolt holes on the TPI intake.

Also go with a hydraulic roller cam.
