Do you think the AVS (s) will sync up on them with just the spring tension being set close? or is it even an issue? What fuel pump will/would you use if this goes in a car? more Current cars: 2000 Dak Quad Cab, 2012 Challenger,1970 Road Runner, 1994 Firehawk 1966 Coronet post sedan, 1988 Corvette, 2005 Magnum RT all SOLD R70RUNNER<---VP Inland Empire Chapter of the MPM

Basicly a street car no cage,subframe connectors,electric water pump. We have never run any other intake though we did try 750 Eddys which were no help. Never changed the stock jetting. We have open spacers under the carbs and the stock Hemi style scoop is sealed to the hood. We used the stock throttle cable. Doug

It is my prototype kit but it works just fine. Shoot me a PM if you're interested. My 505 motor made a little over 600 hp with the CH-28 setup. I was running twin 500 cfm Edelbrock carbs and a Comp 292HR hyd roller cam.

Power dropped off fairly quickly after 6000 rpm but that could be the hyd roller cam as well as the intake. But that is okay, Edelbrock heads on top of a 500 inch shortblock aren't going to make peak power much past 6000 rpm regardless of the cam and intake.

I'd suggest you give me a copy of your book in exchange for such a good tip, but I already bought a copy.

Just curious. Also you have a pm. 72 Demon 340 71 Duster 340 Resto https://board.moparts.org/ubbthreads/show...part=1&vc=1

AndyF I Win A Joined: Jan 2003 Posts: 31,057 Oregon	I used 2 inch tall open spacers because it is a big motor and we were running WOT on the dyno. I didn't try it without the spacers so I'm not sure how much it mattered. The Performer RPM combo used a 1000HP Holley carb. That combo made roughly 20 more ft-lbs and 20 more HP than the CH-28. So only a 3% difference on this motor. The CH-28 setup with the dual 500 cfm carbs ran a lot smoother than the 1000HP Holley. The motor sounded like a stocker with the CH-28 installed.
