I'm am thinking about using gmpp's 12370847 cam with the superram the specs. are: I:234 E:242 at .050 duration and lift .539/.558 with a lsa of 112. The heads are afr 190s and the engine is a 415 stroker with around 11to1. Is this cam overkill or would it work pretty well with the accel? Thanks

 

It will work good with that cam on your 415. My 406 is running a 240/240 @.050 and .595/.595 on a 112 seperation and it works well.

 

What rpm is your motor peaking at? With that cam is it still really torquey. Are you running a stick or auto, what kind of stall? Thanks

 

The engine is still very torquey. The torque peak occured at 4100 RPM and the HP peak occured at 5400 RPM but it still pulls strong to 6200 RPM where I shift. The car is an Auto with a lock-up 3000 stall convertor. It makes 405 RWHP and 437 RWTQ with the convetor locked. Unlocked it makes 497 RWTQ and 391 RWHP.

I always dynp both ways to see what the engine is doing without being influenced by the torque convertor.

 

60lbs of tq is a big differance for the 19hp or something gain by locking the converter.

 

Thank you for answering all my questions.
