Are you sure you put a 750 baseplate on that Pro system mainbody. If you put the one from your 650 on it... it made a 650 again. You can tell the difference by the numbers on the butterflies on the baseplate, or even by looking at their sizes
As I see it if you are launching at 3k plus I doubt you feel a difference. If you were to just hammer I am sure you would get a bog compared to a 650. Now keep in mind That holleys are dry flowed and Demons are wet flowed Edelbrocks i have no idea. I like demon carbs but stay small with a demon and jet up tons over factory if you have a hot motor. I ran a 780 holley on mine to see if it ran any better. I got .3 better with my old 625 VS Road Demon so you can guess What I put back on. I will be switching to a 650 MS when i put the tremec in early this spring.
As of now I have ran a best of 12.86 with the 750 vac 2nd with a 1.73 60ft. Also car is very consestant winning my first money race 3 weeks ago.Car has been running right on the dial.Also I tried a 1'' open spacer it ran a 13.06 first then I put the spacer on and it ran a 13.06 again mph was off just a hair and 60fts were both 1.753 both times.I also tried a 650 pro systems carb from Charlie Booze at BBR and it ran 13.06,13.02,13.00 so that didnt change much.Lucky I didnt buy it first.Well gotta run I hope winter goes fast.
Well And update on the progress of the little Comet that could. Ive put on a set of AFR 165 Comp heads. The Comp has ss valves and a revised cnc program on int. and exh. I purshased them through Maxflow motorsports and had Dusty put them on the sf600 bench they flowed awsome mid lift 3s were very impressive and maxflow was 250cfm @ 600 int. and 225 @ 600 exh. After intalling them I am wondering why it took me so long to make up my mind about them they are freakin killer. You can feel a diference in performance for sure. I guess Ill find out what these heads give me over the stock 302 heads I had befor. That is all I changed later this year I may go with a Hyd. Roller. Im hoping to see at least 12.50s but I dont like to get my hopes up. What an awsome Head.
OK... are we going racing this weekend, saaaay maybe Saturday? If so please let me know and if I can get all the NEW bugs worked out I'll be there! WAITING for your reply what is taking you so long to get back with me Killercomet? That's right, I've got to post this first... right. My bad Looking forward to some fun. Terry
Yes it is an old thread thought Id keep it alive so I can look back for my own refrance to see what I ran with the diferent mods. I guess I should keep It in a file but heck this will do. And yes Bossmav Ill be there this Sat. If the weather is fit.
