They recommend it for durations over 220 degrees and mine is 270 degrees @.050

Doug - The 572 crate you refer to most likely has a mild hyd roller for the street.
The new cam will be a solid roller with 262 @ .050, .715 lift. In a 555 I would think, unless the Demon can actually flow over 1000 cfm, it won't be enough. As I asked before, can it be modified to flow more?
And if not, what would be your recommendation from the Demon line? Price?

If you'll give us a complete list of all the engine, and driveline specs I should be able to point you in the right direction.

I'm sure you could have someone try to port it, but if not done properly it will ruin the carb. It's not something we offer.

On your combination we'd go with a 1000 Race Demon. It will give you better atomization for the fuel with your cam profile, and increased air flow without the choke tower and assembly.

Here's a link to a C-454 dual plane. It's not perfect...but it's the one I was talking about. It will fit a Dominator under an L-88 hood.

I use a 1050 Dominator with annulars on my 540. With my 3.07 gears they help keep throttle response crisp. I originally set it up to work on my 427...but it does Ok on the 540. I've done back to back dyno and strip tests with a Mega $$$$ modified 1400 cfm Dominator and a $1300 AED 1150. Neither made any more power or ran any faster. Well OK..the 1400 made 6 more HP at the peak..but was a slob under 5000 rpm. The AED was slower on my car. Until I change things to move more air..the 1050 is plenty.

Doug - I called your tech service dept to ask more questions about the 1000 and he asked about my engine/driveline. He asked if the 5th gear of the tranny was 1:1 or an OD and, finding it was OD, recommended the Race Demon RS 950 which is essentially a 1050 with annualer boosters since he says the cam will have a hard time with cruising in 5th at low RPM without them. He also said that with the removable sleeves, I could cater the carb size (flow in cfms) to what works the best. So what is your take on this?
