cam lifter help
I have a 1987 firebird with a 305 (LG4 Carb) and I want to do a cam change, but I don't know if it has roller lifters or not. I was wondering if I can put a hydraulic roller cam in if it originally came with a hydraulic flat tappet cam.

An '87 should have roller lifters.
If the block isn't set up for roller lifters, you have to use retrofit cam and lifters - pretty pricey stuff.

Doesn't apply to trucks, so need to be careful about making that association.
'87-up 3rd gens V8's were all roller lifters from the factory.
