Single dominators and between 9.5 - 10.0 if my alcohol riddled memory serves me.

I will say the builds are nearly the same as the ones I just did, with bigger carbs....I know what cam specs are probably close to...hence my guess...

When is dyno day? I didn't get to dyno mine... I will be water dyno this weekend... Haha

Probably a week or so away. Carbs are being built right now and just waiting on some small parts from Summit (intakes, oil pumps, ARP bolts, etc.) All 3 short blocks are assembled so its not too far away.

Rollmaster timing chains? Dart blocks?

Did you have issues with timing set bearing clearing the cam retainer? Double check that make sure thrust is there... I had to clearance retainer for that timing set... Fyi
