New Thor heads flow 530 and 370 cfm unported with 2.5" and 1.88" valves at .750" lift.

Cool Intake allows good access for fine tuning too.

One last look at two piece Intake manifold. MFG's recommendation is for a 1650 cfm dominator.

Looks good, what's the port size?

But they're for a Ford.


I read somewhere that the CNC version will blow 580 on the intake.

You are on to me It did not take you long

Yeah I read a CNC outfit in Michigan is getting 580, not sure what kind of lift but I suspect much higher than .750"

Not sure of the Port size/volume.

Would Love to run these but headers would be hard to get fabbed. I have the "peanut" A-heads which have been around for 20 years and those were hard to get headers for due to their size. They flow 455/335 at .800" (CNC'd) which will do for now

Mr Gadgets

But can we make them fit a Chevy block??

Bore spacing is 4.900" Head studs are 9/16ths Suppose it could be done....or you could move the dist. up front

Not sure if I missed something, but running a cam at .750" lift it seems like you're quickly getting out of the reliability range....no? Especially when everyone is looking for endurance/reliability in offshore performance apps. Until we know what the intake runner volumn is, then I guess it's kind of a moot point anyway.

Am I wrong??? Don't throw too many darts at me!

Of course you are absolutely right.

I care more about .450", .550" and .650" lift and air speed. These heads are made for all out big inch racing, although I bet they would work on big inch, high rpm or big blower motors in front of #6 drives

I was trying to be funny and I am an overly proud Ford guy
