LOL, didn't realize you're in Ohio. I was thinking maybe you were in Lima, Peru.

The SRs I had are not as good as what you have. They flow less than 300 cfm out the box (early castings), you said your heads flow 350+. I did have more compression, but you have 40 more cubic inches (1/2" more stroke). I'm not saying my combo ran this much better than yours and trying to make anyone feel bad, just giving you something to compare it too since they have some similarities.
You can't really compare dynos, but that motor in my car put 508 hp and about 460 ft. lbs. to the rear wheels on the local DynoJet chassis dyno.

I agree with the timing, 30 degrees is too low. You need to be around 36 degrees. CHIP
