Thread: Cam For 427cid Small Block?

Tweet

My current cam is a Comp Cam Hydrolic Roller 230/236 @.05 & .51/.52 lift. This combo puts down about 390 hp at the wheel. I am thinking about maybe going up a size. Crane recommended their HR-306-2s-10. They claim this is designed for stroker motors; @.05 240/248 lift .558/.558 SLA 110 and IC 105. Any input?

what cr do you have? Stroke? Carb? Intake? Heads?

Ooops! I thought I attached my bio. It is there now. Thanks.

with those heads your CR is about 11.2:1, and would handle the next step up cam - although I would want a 106 duration, and lose the Air Gap for a Victor high rise.
I would also swap out those gears for a set of 410's or 488's.
I run the Comp roller 516/535 with almost the same set-up you have in my modified ( with the changes above ) running a 2 speed direct drive tranny & it runs up front

Everything looks good.What I wonder about is how long your tranny will last.

The transmission is a level three from Bowtie Overdrives out of California. It is built to take 500+ Hp and loads of torque. The torque converter feels to loose though. I think a stall around 2600 would work best with a torquey stroker. I just installed the 3.73 rear. I was thinking about 4.11 but was afraid if I did not like the 2004R and put my Turbo400 back in, the car would not be driveable on the highway. I am trying to get a good balance between street and strip.

When you say it looks good, do you mean the current set up or stepping up to the Crane cam?

Thanks for yalls help!!

Thanks for yalls help!! [/QU You would have to go to a higher stall if you went with the other cam and more gear.
