I’m thinking primary’s will be around 68-70 as well.
the carb out of the box had 66 primary and 67 secondaries metering plate and always felt it had a lean surge. (I swapped the plate to run conventional jets in the rear)
The 72/74 ran great no surge I don’t see any soot on my bumper or any...
Update, So I jetted down the primaries from 72 to 66 Stock jet size and engine lost some vacuum and I had to raise the idle a hair. Now for sure there is a WOT hesitation only on WOT no where else, it’s a slight hesitation.
Why would I lose vacuum from a jet swap?
I’ll probably stick the 72s...
If I have a 3k stall wouldn’t I want to have enrichment from the power valve sooner vs later @AJ/FormS ?
Thanks for everyone’s replies! I really do appreciate everyone’s input and personal opinions
I just installed the 10.5 power valve and wow, really responsive off the line at WOT, but I...
Thanks AJ yes this Cam combo I have is really great, the next thing I would do to it is add 1.7 rockers since I already have the magnum heads! Boost my lift and keep the duration the same would probably run good with my 3k stall
Hey guys I been reading up on Holley seems like there’s two ways to select a power valve, which one do you guys use?
In gear warmed up I am at 15 inches of mercury and cruising light throttle I am at 22 inch or mercury
Sorry buddy you were a couple hours too late, I go by first come first serve
@wilb68 contacted me with a PM on Sunday 1:36 PM
You just sent a comment saying you will buy it on
Sunday at 5:54pm
First come first serve here’s the photos whos the *** clown now?.. lol
Next thing I’ll hit the track and see where I am at,
Another mod I was looking at was upgrading my rocker ratio from 1.6 to 1.7 this would give me .481 lift on the exhaust and .465 lift on the intake.
