okay sorry boys i was mistaken they did come with the 2,3 8-plug sorry about that. i was just reading up on them and came acrosses it. they were interduced in 1989
apparently it is alot of work i thought i was the only person to be lucky enought to have this problem but i ended up scraping my truck .. i have to check and make sure i do have one and if i do probably 25.00 US what ever that is CAD i only deal paypal lol. i will post pics friday cause i work...
the 90 had a 2.3L4plug the 95 also had a 2.3L but it was 8 plug the other four plugs dedinate late to burn all the unburn fuel and to make the truck pull a hair better.
and im pretty sure i have a tack for your truck if you want it.
as much as i wanna say that the ranger would win there is no posible way you could not against an LT1 with a 6-speed that would be ridiculously fast the 4.6 would never touch it
IF IT HAS 8 SPARK PLUGS THAT ISN'T THE MOTOR FOR THAT TRUCK!! lol that motor is out of a 1993 to 1995 ranger it will give you bet gas milage and will give you a bit more power this is a really good motor to have in your truck i bought a 1991 ranger with 8 plugs and it didn't belong to that truck...
best and cheapest power would be..
cold air
gut your catylatic converters ..oit cut them off
new plugs
new wires
new fuel filter
electric fan
chip it
underdrive pulley
swapping rear end to different geared rear end to pull better
but that is just about everything i can think of
you will have to probably swap motor and tranny cause the tranny out of the ranger might not bolt up to the 4.6
you will have to rig up the wireing from the f-150 into the rangers wireing harness SOME how that will be a pain
motor mounts and exhaust shouldn't e a problem just fit the mounts...
