My 383 is now running pretty well. It has some cam surge and I am just wondering how much is acceptable. My cam is 236/242-.555/.576. My car is pulling 10-11 inches at 1000rpm, should I have more than that with this setup? And how can I tell if my intake is leaking (internal leak)? thanks.

 

I pulled 6 inches of vacuum with mine, so be happy. That doesn't seem that bad for that big of a cam. mine was only slightly longer duration but was on a tight LSA.

 

I would think you would be seeing more vacume than that. The cam your running is ok but its not that big for a stroker.

 

congrats, must be nice, hoping mine will be firing up this evening.

 

man peoples idea of big cams have really changed in the past few years


anyway is it tuned yet? its been awhile but whats a stock lt1 pull? 13-14

 

I ran that cam in my stock bottom end for a while and with a good tune it had very little cam surge.
