Re: cam timing ?
I'll bet you miss one shift and you're DONE!! It seems that the P/V spec you shoot for in a stick car is around .100".In my 327/automatic Chevelle,I've shot for .050" intake, .060" exhaust.One thing we don't always grasp is that the engine's actual running clearance with the actual race springs is considerably more than on the stand with soft test spring. Was there any consequential engine damage due to the drive line breakage at Mission last year? I almost think that having a ready-to-use spare set of heads ready in an emergency would be a good thing. Problem with a 409 is the cost of a pair of good #690 cores. Get the Edelbrock head approved while you're at it!!
