Single cam from Ec was Percision,150/ the Ec billet cam was 175. It had a lightened cam gear. Large holes in it cut out and the gear was removable. It is now no longer available. The cam in the 31 I'm talking about.

OK MY BAD, STOCK IS 3.4 AND 3.5 IS 31ci. 3.6 IS 33ci. I HAVE YET TO HEAR OF A 3.6 BORE OPPY. I WAS TOLD IT WON'T GO THAT FAR, BUT I DON'T KNOW IF THE BIG BLOCK WILL GO THAT FAR.
JEFF YOU HAVE THAT BIG BLOCK I HAD, WILL IT GO THAT FAR?


Yes, the big block will. However, let's observe the SP engines to see what happens when it's not done with PRECISION.

3.57 = 31, 3.71 = 33.
