That cam will have some overlap and sound lopey at idle so it needs a carb with a more agressive fuel curve. It will be much easier to tune with the right carburator. The Proform carb should be "bang on" right out of the box.

Here's what i would use

Other parts :

(1) felpro 1215 intake gasket with heat crossover block off
(2) thick carb base insulating gasket
(3) a good 14x3 air cleaner assembly with a flo-thru top and drop base for hood clearance
(4) NGK XR5 spark plugs gapped at .035

> degree the cam in and install it on a 104* intake centerline

> tune the ignition curve with 18* of timing at idle and 36-38* total all in by 2600-2800 rpm and disable the vacuum advance

Dam Ron  I never heard of that carb before but it sure does look  great housing everything kinda looks like a demon but with a holley body.

Ya, they (Proform) are basicly a Holley HP series carb with radiused venturies, downleg boosters and billet metering blocks/baseplate without the big pricetag. They work just as good as they look !

i am probably going to be forced into waiting although i have the parts,may have to go in a different car,my fucking boss  :flame:locked us all out of the store and closed the other day,so i may need to sell the charger,hopefully something else works out but if i do sell,this engine will go in
my next hot rod-thanks for the help though Ron ill talk to ya soon

Good combo,

I actually like the Thunder AVS, in fact I swapped one on to my 427" Cobra Replica because the double pumper made it too squirrelly. I like being able to tweak the secondaries..it's a good carb that when it's tuned right really gives away very little to a Holley.

Thats Crappy to hear ANDY, I hope things work out better soon.

Dammit Andy.....so sorry to hear this news. Take care of business first and put the car on the back burner for now. Keep your head up buddy !
