Edelbrock Proflo 4

I want one badly. But I think I need either vortec or Edelbrock heads first?


Edit: Oh yeah, and money

They make all sorts of kits. If you went with one before you did a build, you’d just have to match the heads back to the intake in terms of bolt pattern

I'm still in the process of finalizing all the details on my ProFlo 4 setup but so far I like the Edelbrock MPFI. I had to screw with the linkage bracket and drill another hole. The throttle body is cast and not billet like previous systems I've seen before. The wiring harness is well made, the instructions are simple. The injectors look to be LS2 shorter style. LS1 and LT1 are longer and won't fit. The ECU is not designed to handle any boost but I wonder if a custom tune could be done if you ever wanted to. It does not control the transmission like others like Haltech can. The intake manifold is ok. My single plane Procomp EFI manifold seemed to slightly larger on the ports. Its hard to beat the price when you want a plug and play system that will work with most engines and has the all the features. I did not get the tablet since I have a couple Samsung Note phones and something smaller might be easier to fit on the dash. The gauge layout looks nice to have on the phone while driving and have it be dedicated to the vehicle to monitor vitals. You can download the app for free if you want to play around with the software and there's a demo mode. Looking forward to getting the engine started.

Few videos out there like this one that shows some details

I think if I had to buy it again, I might opt for the other system which is the same price. It has a higher flowing throttle body and I read this intake flows pretty well.

Very happy with this system

What's the part number on that cable Bracket? And does it come with enough bracketry to have a cruise control cable as well?

8041

It comes with a few brackets. Not sure what you need

@pma4x4 check post #11 about part of the problem for the cruise control. I have the vacuum pod on, but nothing hooked up to see if it works due to the throttle lever.
@tenderfoot as Bent said, new heads aren't required.
 
Thanks.

as for the EFI kit option and intake bolt patterns for the heads its either the classic 55-86 intake bolt pattern OR the 96+ Vortec intake bolt pattern. People like me with TBI (87-95) are screwed. I plan to do the center bolt mod with wedges to the 55-86 intake kit. Then once I change heads (that will have the55-86 pattern) I will just do the regular install on the center bolts.

I got to thinking if I get around to spending this kind of $$$$. Then I should probably not order one for an engine of unknown origin. Sure the 350 in my '78 runs great but I bought it without the history on it. I don't even know what size cam is in it, just that a cam was put in it. I have a sb400 that ran great when I pulled it a couple months ago. Might take me a long time but why not build it. Thinking put heads with better flow because wouldn't that help a sb400 a little with cooling issues? A 400 with heads and proflow:D:burnout::weapon42::saweet:

You don't have to know the exact specifications of the cam, just the duration in a range. It asks what vacuum range as well as general build. So I believe that you can get it running with one configuration, then change it later without any more than resetting the base map.

Meh, 400s suck. Big block for the muther' forkin' win
 
I swapped the fuel inlet to the back. Pretty easy. The crossover tube is a bitch to put on the front since the intake sits higher there. So I put the tube on upside down to get the fittings on so the middle part is now taller than each fuel rail. Then I forced it down and it now contours the intake. It does touch the intake but I could put a piece of rubber tube in the center just to keep it off the intake.

The Edelbrock rail fittings are -6AN O-ring. I'm removing the plug at the end of one rail and have both fuel rails go to the Aeromotive FPR and have my fuel line go into the FPR so the rails, and fuel source all go into one point. The fuel pressure sensor will also be in my FPR. Its costing me a crap load of AN fittings and braided hose but it will look decent when done. Already have the FPR from previous 9 second car. Honestly I'd rather have the fuel line from the pump go through each rail then into the FPR but its too many fuel lines going across the engine.
