I have a Holley Pro Dominator tunnel ram they are going on
SandRacer wrote:Thanks, Joe. Holy Cow!, 40 h.p. is beyond my expectations. I may need some help tuning these carbs, I have a Holley Pro Dominator tunnel ram they are going on. I am thinking it should be real easy to match this combo to my heads.
Does anyone have experience tuning the 660's?
a much better Intake than the Holley Pro Dominator Tunnel Ram
was the "highly prized and sought after" Edelbrock Pro Ram II
that Edelbrock Intake has a full 1" plus inch longer runners
and typically makes much more Torque and HP more than the Holley !
on your 406 cid you are not going to make Peak HP
as high as a little 292cid Comp Elim engine.
you need a longer runner than the Holley Intake to make serious Torque
back in 1980's we back-to-back the Edelbrock against the Holley
like everyone else was trying out....the Edelbrock ran faster
down the DragStrip and was worth a lot more Torque than the Holley
even on a hi-rpm little 292cid Engine.
On your 406cid, it will be an even greater gain in Torque !!
I had to spend a week worth of time and effort with a bunch of epoxy
extending the runners on those Holley Intakes and then make a plenum
spacer to get back plenum volume .....it took all this work just
to get back even to an Edelbrock .
in a couple of Hours i'll hopefully find the Dyno Test Data
on the Holley Intake -vs- the Edelbrock Pro Ram II
PS--- Ed-vancedEngines ...knows "Skipper" 's 377 in his Vega,
it had one of those Edelbrock Pro Ram II's
