Sooo....my not so simple quick & dirty CR increase turned out to be a more extensive and very clean rebuild of the Raby kit 2316. Sent the case & heads to Len Hoffman & he claimed he found some more power for me with refresh of the heads and new Crower springs. New JE pistons and reducing deck height to .048" brought calculated CR up to 10.2:1 from the very conservative 8.2:1 I had before. Seat of pants showed much more crisp throttle response that Jake promised and definitely more "grunt". Chassis Dyno run last September on the old setup showed 135 Hp and 130 torque. Today's was 166 HP and over 160 torque....sweet! Going to have a blast at VIR next weekend!

WOW! That is great. Would love to be there to see that run/runs. I was born in South Boston, just 35-40 miles east of VIR.

Told ya so.
Nice.
1. Check your dizzy. That pimple at 3600 RPM points me in that direction.
2. What do you use for induction?
3. Which cam and how is the idle?
Idle with that cam is smooth as stock @ 1,000 RPM if its tuned right. I know :-)
That idle should be slick as glass with no "lope" at all.. I HATE a lope, silky smooth! None of my cams have a lope!
Sounds little rich at idle if it has a lope.
