Crane Z-Cam 268 Rough Choppy Lopey Idle 1959 283 Chevy Small Block

This is my 1959 283 Idling with a Crane 268 Z-cam. Cam specs are 218/230 @ .050 268/280 ADV .459/.486 lift 112 LSA. The engine is bored +.040, flat top pistons, '416 heads, Summit intake, and an Edelbrock 1406 carburetor. It runs about 10:1 compression and burns with a stock HEI distributor and coil. The Exhaust manifolds are stock for a 1980 GM truck as is the y-pipe and cat. The Exhaust outlet is 2 1/2" and the cat is my muffler right now.
