I weighed the two and decided for being the same weight Id run the pro flo for a while. It is better constructed and it fits in my hood. I didnt seem to notice any difference in the two as far as rpm limit. The difference was a half of mph and the car was 30lbs lighter when it picked up the half mph with the holley. Also launched better and wasnt spinning. So its a toss up. Ill probably throw one on mid season and see what it does.
Visually the Holley intake looks nicer...although having seen the quality of mine, I've no doubt the Edelbrock will be much superior quality.
I absolutely hate how the fittings are BPT and on the bottom of the intake. I was going to tap a fitting on the rear to run a vacuum block.
Otherwise it didnt matter to me either way. I guess end of the day the pro flo has longer runners and I want to see if I can get anymore rpm out of it with the 3/8 pushrods. Even 100-200 more rpm would be great. Mid season Ill put a cam in that is made for this combo.
Just for a freshen up. I bought all new fuel lines. Found a deal on some goodrich ptfe.
New pair of aem's with a straight 6oring-8an. No more check valves. Now we can see where these pumps completely run out.
I added a few pictures since people always ask me how the pumps are situated. twin 10an from tank to pump. 8an from each pump to the rear of each fuel rail.
