Hi, I have a '92 F-250 with a 5.8 Windsor and a ZF S-542 tranny. Over time so far I have added a Comp Cams #35-255-5 cam and matching springs and lifters, I have bought an Edelbrock Performer truck EFI intake, and just a couple of hours ago I bought a set of Pro Comp 64cc chamber 190cc runner heads packing 2.02 int and 1.60 exh valves turbo swirl aluminum heads with a 3 angle valve job, my block is bored .030 over, and I'm wanting to drop a 408 or 418 stroker kit in it. So, what's the best really cheap way to come up with wiring for a 5.8 maf instead of a 5.8 sd. If I use a Mustang maf brain on it for a bit how bad will it hurt it until I can buy one tuned just for my engine, and lastly since I have a good torquy flat tappet cam is it worth it enough to go find a proper roller block and new hydraulic roller cam for my Windsor stroker?

 

Yes on the roller block, with modern oils it's anybody's guess how long a flat tappet cam will last these days.

As for controlling this build, a Mustang PCM with a Moates Quarterhorse would be the way to go, you will need significantly larger than stock injectors and MAF meter for this stroker and that won't run on a stock computer so you will need tuning ability right from the get go.

 

This is going to be some heavy tuning with all that air going past your meter. Probably going to need a scaled tune. For all this money you are putting into your motor, you don't want to drive it until you get it tuned.

Agree with the man up there about Mustang PCM (probably want A9L/A9P) and Quarterhorse RT. You will also need a fuel injector harness. You can modify what you have now but it would be easy to just overlay a new harness on top.

 

This brings up another question. I haven't got the chance to get the stroker kit yet but I have the heads, cam, and intake. The engine block was assembled about 10,000 miles ago already bored .030 with the stock intake, E7 heads, and rotating assembly. If I were to wait on getting the stroker kit until next year and go ahead and install the heads and intake and get the brain and qh, can I get the size injectors that I will need for the stroker and dial them down with the qh or should I just stick to stockpiling parts until I get everything and then build it? I'm not sure exactly how the qh works, but it seems to me that it would be able to dial in the fuel flow rate and I'd like to be able to go ahead and use my heads and intake since I have $1,300 in them already. I know that if I use the heads already that I'll need more fuel flow and I'd rather not have to buy a set of injectors now and then a set next year. One more thing, anyone have a suggestion on flow rate for the 408 with the setup we've mentioned? I don't know how much hp it will create so I'm rough figuring that I will need a flow rate of 30-40 lbs, but that a pretty large spread.
