I have read and read and I get a lot of suggestions but I can not make up my mind on a new cam.

The motor is a 1968 YC 400 bored +.030 with #15 heads (stock valves but new valve job with seals and double comp springs)) all new bearings and fully balanced with original rods and new 4 relief pistons, Edlebrock performer intake and 1407 carb, new Petronix HEI ignition, Summit headers into H-pipe and full 2 1/2" exhaust, TH350 with shift kit and new 2000 stall converter, posi rear and 3.42 gears. I have new comp roller rockers and pushrods. All engine acessories and power robbing devices are still connected with power brakes also. Suspect C/R at least 10:1??

I would like a cam that will give good street performance and fuel economy, will not be taken to the strip. i just want a great feeling street machine.

I have looked at the Summit K2801 cam and the Crane powermax 272-2 cam and either sounds good. What are your suggestions??

Thanks for all the excellent help you have here!!

It looks like you have a well thought-out engine combo. Your cam choices are both fairly good ones, but with 10:1 compression I would lean towards using a slightly bigger cam.

I would use the Crower 'Beast' 60916 cam (221/229,.455/.470") to help keep this high-compression engine from detonating on premium pump gas. It will work nicely with the rest of your combo and won't be too hard on fuel. I would also recommend a Q-jet carb for the best fuel economy.

I use the Crane H272-2 cam in mine. Where I think the one you are looking at is 216/216 and about .454/.454 lift the H272-2 is 216/228 and .454/.480 lift. I have been well pleased. Very responsive, with great bottom end. I have #48 heads and Ram Air III manifolds, cast iron intake and a Cliff Ruggles prepped 800 cfm qjet. I use 93 octane and have no detonation issues.
