I have an opportunity to get a 1988 f-150 5.0 efi that runs at a reasonable price. I was wondering if this is a good engine to install in my Maverick??? Not looking for anything that is extremely fast, but definitely more power than I currently have with the I6. I am looking to put a carb. on it. What else will I need for this swap?
Its pretty much all here. http://mmb.maverick.to/showthread.php?t=4581 You'll want to read thru the posts too.
Good choice. You'll need to decide on what set of accessories, brackets, pulleys, manual/electric fuel pump, ignition, exhaust manifolds/headers, ... you'll use. See the Tech Article for all the things you're going to need which ever decisions you make. OOPS!! I missed the "EFI" in your question. Can't comment on that.
While not the most powerful 5.0, a truck motor should produce at least 50Hp more than a stock 302 from the 70s(5.0 HO is worth close to 100Hp)... I'm not sure the truck EFI intake will clear the hood, but a HO intake(upper & lower)from Stang or LSC Lincoln of similar year is a bolt on, neither truck or Stang intake clears the shock tower/firewall brace... To use the HO intake you'd also need throttle body, egr spacer, Mustang throttle cable and maybe Mustang fuel rails... Also you'll have to fab a inline fuel pump and return line back to the tank, as the EFI system regulates fuel pressure by returning unused fuel to the tank... BTW the truck uses batch fire inj and 15426378 firing order vs the sequential HO firing order of 13726548 for Stang, you'd need to use the truck harness and ECM with either intake system... BTW#2 the block should be set up for a roller cam but will have a flat tappet installed, trucks didn't get roller till the '92 Model when to mass air and SEFI firing became std.
I am probably going to go with a carb on the motor. Is it easy to convert it to a roller motor? And will it produce the same results as a Factory Roller motor. If so I could just use the motor for a while and possibly in the future rebuild it and convert it to a roller motor?
You probably better worry about getting it swapped into the car first, which is going to require a front sump oil pan and early front timing cover(needs to '70/later as '69/earlier uses a passenger side lower hose) to mount the mechanical fuel pump... I just did this for the Comet but it was already V8 so I could rob all the parts for the 5.0 from the orig 302...
Does anyone know if I can use the flex plate from the F-150 transmission on the original I-6 transmission that is already in the Maverick? Where is the best place to get a front sump oil pan, motor mounts, and timing cover.
Best... Junkyard, if you have a pull-n-pay close, many 'standard' yards got rid of thier Mavs long ago. Pan and timing cover off any 70's 302, u probably can get them off eBay and maybe summit or jegs (pan). Some members put up the frame mounts here, the metal/rubber motor mounts u can get from any parts store. Iirc, u can use the '88 tc if you're going to use the sepitine belt system (reversed water pump), some of them had the space for the mechanical fuel pump. (My 86 HO did)
Would you recommend installing an electric fuel pump? and would that avoid having to get a timing cover? Would like to keep serpentine belt if possible unless there are down sides to that?
Yes for the electric fuel pump F/P... Depending on what accessories you use you may need a A/C compressor eleminator bracket and pulley... If you have all pulleys jse a small diameter piece of rope to determine belt wrap and length... Mine is a '92 Mustang engine but had a flat tappet cam in it when I bought it(engine was fresh never fired)... Rather than use the rumpty-rump cam installed, I bought a the smallest Lunati flat tappet Voodoo cam... I looked around for a used HO cam but never located one I trusted, new roller cams with all the necessary pieces were out of the budget... Engine runs nice on the Voodoo idles 17" vacuum, at the moment I've only run it on my buddies break in stand...
You're going to need to swap the timing cover too, unless you retain the truck's accessory drive. The timing cover on that truck motor uses a reverse rotation waterpump and the timing cover behind it wil not accept a std rotation pump. It may be easier to just get a late 80's to 91 Crown Vic/Towncar/Marquis 5.0 then carb and recam it. These motors used a std rotation waterpump and timing cover which you can either retain the alternator and P/S from it, or covert to a V belt setup. Fuel pump ? That's easy, just use a 12S MrGasket electric.
