Performance timing

Also i have a stock torque converter.
That stock TC is gonna kill your performance with a 292/292/112 cam and 9.1Scr.
If your combo is already assembled, Try to leave that TC in there for a week or so. By that time you will have a pretty good idea of when,where, and how badly it sux. And better, you will have a good idea where the power is, and what stall-rpm to order up. This will vary somewhat with your rear gear. With a 9.1Scr 318, I predict that you will need at least 3.91s and at least a 3200TC for a streeter.
Forget fuel economy, just furgetabowdit. With just 98* of power extraction, just 106* of compression, and a fairly hefty effective overlap of 60*, Plus cylinder pressure down around 125psi, there is almost nothing you can do to improve it's fuel economy........ but I suspect you knew that going in,lol.
In my 367 that cam did not come alive until 5200, and the 108 version I had, just rocked to deep into the 6000s! I shifted it at 7000plus which, with my trans, allowed the rpm to drop back to 5000 ........ "perfect" in my combo.
