That sounds like the "Dial-A-Flow". It was a Port-O-Sonic upfitted with the removable inserts. I have never used the PoS, but I have always liked the looks of it. It is a fairly aggressive intake though... the T289 would be a better streeter IMO. Edit: Fwiw, the 360 is the low profile single plane with a center divider. It's not a dual plane in the way most are, it just divides the carb between cylinder banks.
Why??? Are you a junk collector or something? Are you related to Fred G. Sanford (that's S-A-N-F-O-R-D-period)?...
I use it (the chevy piston) as a paperweight. Can you think of anything better to do with chevy parts
Yes, it is a P-O-S. lol That's Port-O-Sonic, a real good manifold after the modifications. I don't know how it will run on the street, it was a track only piece.
I'd be interested in hearing from anyone with this setup too. I have the same intake and a 750 Holley waiting to cap my 302. John B
knock on wood bud, mine corroded out near the rear passenger side. I'm in the market for a new intake as well, the Performer 289 aint gonna cut it when I FINALLY get this thing back on the road.
I ran a offy 360 degreeon my 70 4 barrel 351c and it was a good matchup topped with a 780 holley double pumper. I bought the stealth that I have on my 72 on ebay for 99 bucks, almost new. I really like it.
The Performer RPM Air Gap is all the rage right now and is getting rave reviews in the car magazines...
I would have to agree with Ratio411. Torker 289 I ran one on basically stock 302 8.5:1 dished cast pistons stock '74 heads J C Whitteney $80 headers holley 4010 (the ones that looked like the autolite 4100 carbs) stock C-4 stock 3.00 rear. It ran great kept up with the new vettes at the time('87 or so) and got about 17 around town and approx 22 hwy I would also have to partially agree/disagree with Rick Book yes there is no garenteed "good combo" but on a whole when your speaking of a certain type of combo stock cam specs head specs etc do vary slightly but not enough to make a huge difference in the same token some of it is general knowledge...your not going to stick a tunnel ram with dual dominators on a stock motor and expect it to perform well and get great mileage thats not what they are designed for. JM2C. Not lookin to step on anyones toes
Probably cuz ole Vic buys full page ads. While the Air Gaps seem to have a little more HP on the top end, I would probably credit that to the increased height, rather than the air gap. In incoming fuel charge, after the motor is at operating temp, is not significantly different.
