My buddy has a 3rd Gen Camaro that has an older style GM Goodwrench crate engine SBC in it. It's a flat tappet hydraulic motor. Carb, mechanical pump and dist. No spider tray and has no cam retaining plate.
He wanted one of my spare cams that I had (CC503) for his engine. Figured it would be a direct swap...
Well after trying to install the new double roller timing set, I discovered that the bolt patter of the LT1 cam doesn't match the SBC timing gear (the grouping is tigher on the LT1 cam). Furthermore, the LT1 cam face is not flat, it has a step to it.
My first thoughts are to just use a stock LT1 timing set.

Does anyone know if this cam will work with the Stock LT1 cam gear will work in this motor (I know it has the teeth in the back for the water pump drive)?
Does the fact that the motor has no cam retaining plate matter?
Does he need a cam made for a SBC?
Your help is greatly appreciated.

He will need some kind of cam retention device a roller cam or hydraulic roller cam can not walk back and fourth with out damaging all the lifters. either he can get a retro fit kit. which is very expensive or just buy a flat tappet cam.

So a haudralic flat tappet cam can walk and a hydraulic roller cam can't without causing damage? I don't see what makes the cams different. Can someone explain?

a flat tappet cam the lifters spin in the bore. at least they are supposed to. a hydraulic roller and full roller they are just followers. hence the links that lock them together.

He needs an aftermarket retro-fit roller cam kit to put a roller cam into a non-roller engine.

Well he's ordering a hydralic flat tappet cam...
I guess I can give the CC503 to someone else.
