post up them early to mid 90's F150's!

Very nice truck Mike. I've got a 92F150 XLT that's in pretty rough shape right now. She still drives but she needs a good amount of work. I can't decide if I want to do an engine swap and turn it into a street truck or swap frames and throw a small lift and bigger tires.

Thank you! Literally not a bolt on it that I haven't touched. It's about time to go through it with all new window felts, paint job, and new trim on the windows and the like. Then my oldest gets it as his first vehicle. Pretty sure I'm going to cry when he tears it up... lol

Tough call on your truck. Post it up!

The nice thing about these trucks is they are almost like mustangs and parts are a dime a dozen. Especially through the LMC Truck catalog. I'll have to wait till my brother drops my truck back off to me. He lives out in Terrell and needed a vehicle that can haul some stuff.

The real challenge with these trucks is tuning them. The 5.8's were SD until 96 so only one year had MAF and OBDII. The 5.0's went Mass Air in 94, but good luck with finding a tuner that has a strategy file for it. You can get the FMS MAF conversion with the AKCO ECM and it's similar to the BIO, but with 30# injectors. Even then you need a broke strategy file, and the only one I know of is from PopsRacing (AHACA) for $200. The 5.0's use the AOD trans so most likely any mustanf harness and ECM can be used with some adaptors from RJM.

Any idea on how much work it would be to do a terminator swap into one of these?

This is a drawback I've looked into, if/when the stock 351 takes a dump. I'd hate to leave one with the SD setup, but switching to mass air and full roller is highly desirable. That day will come, maybe by then I'll have a plan.

Not sure what the point of that would be. 4.6 is too small with not enough torque down low to be an improvement over a built 351. You could do a complete Gen2 Lightning swap since it already has the right transmission for the job. To go with a standard trans you need a TKO600 with the shifter in the middle position. I'm sure a modular motor would require custom mounts as well. You would need to repin the ECM to accept the new harness or go with a FAST and the Bauminator for the trans control.

Stock SD, stock shortblock, AFR 185's, Stock intak, stock tb, Vortech V2 S-Trim with a 8"/2.9" pulley combo, 60# injectors, Long Bars, PI 2800 stall, would get you close if not in the high 10's.

Mainly because I have access to a terminator engine with low miles that'll cost me next to nothing to pick up, if I decided I want it.

Damn, as long as it's still streetable. I'd still want to throw shit in the bed and haul stuff.

My 95 was a Canadian build 5.8 mass air, for what it's worth.

[Diabolic]

Man I drive mine all the time. I put over 120 miles on it this week. I don't have the converter or slicks so I rob myself of probalby 1/2 a second in the qtr, but I can still pull heavy loads without the trans overheating. A guy named Huffentuff over on NLOC had that exact combo and ran 10's for a long time. He used 30# injectors with an FMU. He ran high 11's with a 100% stock longblock and the Vortech for years.

There's a tuner on this board, Sam88GT I think, who was talking about tuning SD on LS truck motors in another thread. if you can tune Chebby SD, couldn't you tune Ford SD? Jetfast has stated in the past that the same potential is there, if I'm not misquoting him.

[Diabolic]

No it's definately possible. I've burned and sold many chips to my fellow Lightning owners. I tuned my Lighting when it was Speed Density, and I tune my 95 Bronco that is also Speed Density. Just saying it requires an investment of time to learn, and money to buy the laptop, wideband, strategy file, Qhuarter Horse, and Binary Editor. You can't just go to a speed shop and have it tuned.

[barronj]

Sam suggested that if there were a dozen tuning shops, only or two *knew* speed density.

[Diabolic]

The challenge with speed density is that in open loop all the points of the VE table from roughly 70%-100% become critical. Since the engine has no MAF meter to measure the volume of incoming air, it gives a pre set amount of fuel based off the value in the stock VE table. When you increase the airflow by adding say heads or an exhaust then these values must be increased so that the actual AFR matches the commanded AFR in the base fuel table. Realistically this needs to be done for every single cell in the VE tables from the lowest MAP value to the HIghest MAP value and at every RPM point on the grid. This isn't 100% necessary when in closed loop because of adaptive learning, but it's critical for open loop operation. Startup fueling can also be thrown way off because it too uses open loop fueling. If the mods increase the airflow then the engine will run lean when not in closed loop. Another challenge with the factory SD is that it only measures up to 100% load, and after that you just get what you asked for in the top row. You can crutch this using the wot fuel multiplier to add more fuel as the RPM's increase. This isn't such a big deal for Centrifucal SC'er's, but can be extremely difficult to get right on a turbo application that may see boost at part throttle because the multiplier isn't in use.

I'm sure others can chime in to add to this. Just a brief overview of the challenges with SD. It can be made to work very well, but takes far more time than a MAF equipped vehicle to tune "correctly".
