I'm torn everybody, i have the choice between an LT1 cam, and a ZZ4. Which will be better for my setup, not only for best performance, but drivability. I have the 305, with Vortec heads, The Edelbrock Performer Manifold, A set of 1 5/8 headers, w/ Y-pipe. and a soon to be 3" exhaust all the way back. What do you guys think I should do?

 

Dont forget that if you go with LT4 cam you also need to buy 1.6 rocker arms.

ZZ4 cam is too much for a 305. You don't need 1.6 rockers for the LT4 cam. They just have to be self aligning because there are no guideplates on centerbolt heads.

No, you dont... It'll work with 1.5's, 1.6's, even 1.7's if your springs and heads will work.

The ZZ4 cam is too big for a stock 305 TBI, in my opinion. The L98 or LT1 cams are a better choice.

I AGREE THAT A ZZ4 IS TO BIG FOR A 305TBI.. I WOULD SAY THE LT1 CAM IS A MUCH BETTER CHOICE. JUST REMEMBER TO VERIFY THAT YOUR VAVLE SPRINGS CAN HANDLE THE CAM. IF YOU SWAP THE SPRINGS EITHER LT1 OR LT4 SPRINGS WILL WORK JUST FINE.
