A Carter AVS is not a spread bore, I have run this combo in my 68 Cuda since 1978. For a thermoquad to work without a spacer you would have to machine this manifold. Also my car will still fit in G with this combo. Before you worry to much about this combo, which there aren't that many out there, you might want to take a look at the 91 Corvette which holds the G/SA record at 10.54 at 124 or the 73 Pontiac TA - 455 at 306 hp. If you think all this aluminum stuff helps so much (other than weight) then why is the 70 Duster with aluminum heads 2 hp less than with cast iron heads? The AVS 340 combo & the 383 only take a 1 hp hit with aluminum heads & be prepared to spend big $$$$ to make them legal. Wish I could use a Quick fuel carb or a 4 speed auto trans. Didn't powerglide combo's got a 3 speed, why can't I run a 4 speed auto? That would help way more than a manifold. Can someone tell me, what is stock about stock eliminator these days. Just sayin.

Having a hard time finding those 4bbl intakes that were an over the counter option on 72-82 302's, should just let them run with a performer as well along with the 600cfm holley. Of course the hp will have to be lowered to 100-105hp to make it "fair".

(75 mustang at 2000# to fit U/SA?? that aught to set some records lol)

James, how you doing? My car was an original 4 speed, it would be cool, thanks.

One thought on this also. First hi Chuck I wrote in a bad why and your right there are maybe 5-8 cars this effects. In 1970 Chrysler sold this intake as a replacement. They didn't sell aluminum heads. Stock didn't come with roller rockers and the list goes on. But this intake was.
Also Chuck I should know better. Earl Blake's car is in my garage and the 68 Barracuda surely still runs 'G". Sorry to forget you on that. Actually not sure "D" is in trouble either. Trying to get my Dart down to 3010 lbs with me in it and still work might be difficult.

what makes anyone think that the edelbrock intake is worth hp? the factory cast iron intake is a pretty good piece.

hi, for what it's worth, had both on flow bench, attached to 587 head. the flow curve was damn close to the same. prob 3 CFM max difference. I had the 2100 manifold to compare with.

Might be some HP in it being aluminum (cooler mixture charge) but I'm not changing unless I need the weight moved to the rear, still gotta run the same weight no mater where it's at, right? As far as the aluminum head, heat dissipation compression loss, replacement iron head would be better. Lighter weight yea, but most don't have any trouble getting the wheels in the air. Been watching.
I'll find out soon
