I am really liking the 360 combo. Even carrying a few extra pounds, it seems like the logical way to go.
For whatever reason, it just seems like nobody has got the Super Victor to outperform the old Victor 340.

A few years ago(maybe 10 years) I read an article about someone mating up a sb chevy victor intake to a 340 and running in ss/GT. They said the chevy intake outperformed the mopar intake by a bunch.

Yeah, I know of folks that have done that. I just dont know how big of an advantage it is, if any.

Hamburger use to have an adapter to use a small block Chevy intake on a small block Mopar. But that was in the '70's or '80's before the Mopar selection expanded.

I knew Louis Smith had done some testing with the Chevy intakes. I'm really suprised that in todays world of r&d that no one has ever just back to backed a bunch of intakes, including the Chevy against the Mopar intake.
We did a dyno test on one of our customers engines ( at his request and expense ) , its a 355 Chevy, roughly 600hp, and the winner was a World Products intake.
Some mentioned the Port A Sonic was better on the 360....what makes the 360 like a different intake than the 340 ?

The 340s liked the Victor and the 360s liked the Port-O-Sonic. Looking into a sheet metal design would be interesting. BTW the engines tested were front runners in their time as was the shop so the tests were legit.

This exactly what I found with similar testing. Also, on the 340 (72-73 Low Compression), the Holley Strip Dominator ran the same ET as the Victor, but the Victor was 1 mph faster. Bill Rolik

I have a Magnum head that was donated to me for R&D, but, haven't persued yet.

Intake has my valve job using the factory valve. Exhaust was completely unmodified. It was done after .500"
As ugly as it is, it flows better than an unported LA head. I'll still take the 360 LA head for racing, as long as porting is allowed.

when we ran the 71 Duster TQ combo in SS/IA, we also used the Holley Strip Dominator (modified/with spacers) for the best HP/TQ. I still feel the 71 Hi comp/small TQ/308 head combo is very viable when compared to the 360
