I would bet a pretty darn good amount of money that stroker mentioned above with a decent sized cam will continue to ET better with each increase in carb size from 650 to 750 to 950, and perhaps even beyond in size, depending on a couple of other factors.It will easily run its worst ON THE TRACK with the 650.

Zero doubt about it.


I have ( in a single day) track tested a pro systems 750, pro systems 1000, race demon 1025 and a 1100 pro systems dominator on a eddie headed 416 without a ton of compression( 12 to 1 ish)...the fastest two carbs were the 1025 rs race demon and the dominator, and it wasnt even close.The 1025 being 8 hundreds better than patricks 1000 hp surprised me a little.

Thanks to Patrick for allowing me to use the carbs, i bought the dominator and still have it, and sold the 1025 a short while later on Moparts.
