im looking to do a 5.0 swap into an 99 v6 f-150...i did it in a ranger but they had specific mounts made for the crossmember....Does anyone kno what or if id have to get a diff cross member or if all i have to do is drill newqw holes in the crosmember for the mounts??? please someone either pm or get back to me...im only confused on the the mounting of the engine...everything else im good with and ill for sure post up some pics...

 

i think the cross member will be alright because the 4.2 has a deeper oil pan than the 5.0 but i think you will need to drill holes for the mounts because i think they only make kits for this to work with a 4.6. otherwise everything else should bolt right up.

 

just FYI you wont have the ability to send or recieve PM's until you have 100 posts and have been here 3 months

post some pictures when you get things started. if you need help with anything about wiring i can try to help you out.

I've done many engine swaps, I think that it will all work for you. Try getting the 5.0 out of a Explorer, with the complete wire harness and computer. This will possibly save you some issues with OBDII. The oil pan on the explorer might also be needed, and possibly the exhaust, but I hope not, the exhaust manifolds really sucked (note; contrary to belief the iron manifolds are better than the steel). Now I should not mention this because I do buy and sell engines, but if you get a early year 96 it will have three bar GT40 heads, they are better than the later GT40P heads, although bench flow shows otherwise. You also get a GT40 intake too. You would definitly want to swap in a different cam though. The explorer cam is junk, however the 93-95 Mustang Cobra cam is a good truck cam with it's wide lobe sep. for vacuum signal just install a set of 1.73 roller rockers to get the Cobra cam benifit. Other wise a regular GT cam with the same rockers is not bad for a truck, they are also plentiful.

well i have an 88 5.0 out of a mustang with an aod trans so...the exploer thing wont work but i appreciate the suggestion...i mean but from what ive been hearing is all i gotta do is just re drill holes in the cross to mount the motor if thats the case im a go for the project...i just kno my friend is swapping a 4.6 into an 88 and hes gotta buy a new crossmember, but thanks for everyones help and more input would be much needed

 

First the AOD from the stang will be good if your truck has a stick, and your going auto. But you should really be using an AODE or better a 4R70W so the electronics match the truck. The 4R70W is also a much more durable unit.
Now to the mustang motor, that shortblock is very good. You WILL!!! want to install a new preferably melling oil pump( do this for the love of god). The stock Mustang cam is actually known to the Mustang crowd to be stronger than the Cobra cam after install a set of the Cobra 1.73 rockers. The Cobra cam though is better for a truck in design. Sorry to hear that you are going to use those stock mustang E7TE heads, they ARE Fords WORST 5.0 heads, and dont even make good boat anchors. No, porting the emission bump in the exhaust does not help for the work to do so, I've been there-done that. You should seriously get a set of Gt40 or aftermarket heads. The Gt40's will also give you more compression. The Mustang intake was a big deal back in like 1990 for people with non HO motors. Now you can pick them up for like $20. which is scrap aluminum equivilant. The GT40 intake breaths MUCH better without sacrificing torque, I dont believe any aftermarkets can claim that (except there is a crazy, I believe Brodix out there for BIG $$$).
I'm not saying buy them from me. I do have and sell them though. Get them local if you can. There is a huge difference.

Best of luck

PS: If your truck is an auto, and the transmission is still good, why not just use it? It is the same pattern as a 5.0, just it's internals are possibly???? not quite as strong. That torque converter if used on your 5.0 will also most likely make that truck launch like a rocket ( get a posi in the rear) My old company had a Ford van 4.2 which I hated, but if you stomped on it, the trans. would do a hard shift and the truck did move. I can only believe that the converter had a higher stall, and trans lower gearing.

 

welli have a set of 351 winsor jr heads with 1.60 exhaust valves and 2.02 intake with 1.72 scorpion roller rockers. Im picking what type of cam i want and im making it carb'd. Well ill have to possibly try that...the whole my tranny on the 5.0 cuz it has been rebuilt with a shift kit...Im probably starting it in like a month and my neighbor im buying the motor from told me its forged and told me the year and car so i could verify......but all in all i cant start this thing untill i get my bike so im not stuck with no transportation.
thanks for all your help

 

Sounds like you have a very good foundation there. As for your camshaft, Just DONT GO TOO BIG. You have alot of engine head there for a basically small V8, and remember it's going into a relitively heavy truck compared to a stang. Go for a strong lower end torque cam with good vacuum. You need torque in a truck to get it going, not HP at Hi RPM. I still feel that a stock Cobra cam is you best bet for bottom end, while retaining mid range and enough hier RPM. Lobe sep was like 118 on it.
