Camshaft

I bought a BAE 456 stage 5 engine intake to pan, formerly used with a screw , NHRA TAD
I'll run it with a roots 14-71 HH , 3 speed , with convertor set-up
is it better to change camshaft to get the best of this new combo
The cam is : .505 cam lift , 296 deg at .050


Thanks

Claude

 

I think it would run OK, but talk to the camshaft experts at Crane or Erson, and they can set you up for your combination. Personally, with that size of motor, I would make sure you bring the compression up to at least 11.2, then go with an R296-500-16, or a R296-4778-14. They seem to work pretty well.

Question

Hey Claude Check Your Pm And Get Back To Me Ok Thanx

 

we put a new cam in and the car didn't run worth a sh-t and to find out they sent us a cam for a screw and not for a roots and that solved the problem..

 

screw/roots difference

what was the difference between the cam's,what was your best et/speed before /after?

 

over lap and lob seperation...I called keith black and talked to one of the guys in the shop and he is the one that told me what was wrong, he also told me the part# for the cam iam running now
