Default More engine details

More details on my motor? No problem! Anecdotally, an engine identical except that it has a Holley 750 vac-sec in a Pantera (don't know if the different exhaust systems between the Cobra and Pantera would make a difference) pulls hard all the way to a 7k rev limiter. I haven't had the guts to try that anywhere yet, but it hits my 6k limiter without a fall-off.

Anyway, here are the details:

'74 block @ 0.060 overbore
KB-151 hyper pistons
CompCams 282s (single pattern 236@.050, .528 lift - lots of P/V clearance)
Torker II intake
Edel 6025 heads (RPM with the 2.02/1.6 valves)
Holley 650 dp (67 primary, 78 secondary)
Mallory ignition system (HyFire IV/c box, ProMaster coil, and Unilite dist - out-of-the-box advance curve, and don't know what that is)
The only accessories it drives are the waterpump, alternator, and PS pump
With the KB-151s and the 60cc heads, compression is calculated to be 10.7:1

The simulator I used shows power peaking at 6k - if you think an Edelbrock 750 would let me spin it to 6500-6800, without the stumble on tip-in I've currently got, I'd be thrilled!

Thanks,

JLW
