EFI 351w intake, which one???

SpareParts · 06-26-2007, 06:33 PM

Ok, I'm building a horse of a different color. This is for my 72 Bronco, I have a 351w, 30 over, 10.5:1 comp., Speedpro pistons, ported GT40 heads, Comp Cams cam 493 int. 512 ext. 218/226 dur., Comp. Magnum rockers, shorty headers, (2) 2.5 into (1) 3 exhaust w/ Magnaflow muffler. The motor is fully balanced and has around 6500 miles on it with a Edelbrock RPM intake and 600cfm carb. it should dyno around 400hp. and 460 tq. It runs good but I need FI for the hill climbs and side angles.

I need to know which FI intake, TB, injectors will work well with this combo.

I have an Edelbrock 5.0 intake, it's around $300 for the 351w lower. How many HP will this support? Is there a better intake?

Any advice will help, Thanks in advance.

I should have also mentioned that I'm using a 92' mustang wiring harness. I currently have the 92' ecm. w/mass air, 90's lincoln intake w/19 lbs. injectors and 60mm TB.

which edlebrock intake? the performer? its a nice little torky intake that works well down low.

Sorry, it is the Performer 5.0. I was looking at their site and it shows with their heads on a 302 only 300hp?

The GT40 intake states 350hp.

I just don't want to loose power with going to EFI.

how much do your heads flow? Can't make even stupid guess without that. Since they're not just stock gt40's anymore even guessing is kinda silly.

The heads are not ported yet, my builder has flowbenched them. He said they flow 15% better than the 72' heads on it now. When he gets done with the port work, he said the will easily flow 25% better. I don't have any of the flow bench #'s. He plans on getting 10% over the stock GT40 heads.

from my desktop dyno software you should probably do pretty well on that combo. I'm showing over 350bhp and a fat tq curve.
