It sounds like its really gonna happen this time with a 32V Dominion headed LT1 Everyone is dying to see the numbers this motor is going to make N/A.

Yea it's going to be sweet... a real different between ohv and ohc

Injuneer

The Dominions are not "OHC".... they are actuated by pushrods just like every other head for the LT1. Look a bit closer at the pictures. Those are not camshafts - they are rocker shafts.

Yeah, it's the diff between 2 valves and 4 valves.... To make a good comparison I think you need to do a ton of work to it to make it work!

Yeah, the OHV motors seem to still beat out the OHC motors.

Bret, since you are working on a set right now does that mean you have some preliminary flow numbers to share with us? And what do you expect to see from the heads once they are finished?

Injuneer

When the heads first came out, GM High-Tech Performance got a set from Dominion, and sent them to Second Street Speed for flow testing. I think those are the "as cast" results that are published in the various "LT1 Head Flow Comparo" tables that are available on the Internet.

LIFT - - - I - - - - E
0.100" - 107.6 - 92.1
0.200" - 188.8 - 165.8
0.300" - 254.6 - 204.2
0.400" - 294.5 - 239.7
0.500" - 314.5 - 259.4
0.600" - 325.0 - 270.7

Unstable Bob's were worked, and I think he has flow numbers a bit higher than those.

SStrokerAce

No I dont have them for it yet, his are going to be worked over even more than normal. Remember that these heads rarely see over .500 lift.

Holy crap those are nice exhaust numbers! Does it mention if that's with a tube or not?
