will these engines work?????

[87_crown_vic]

i was wondering if these motors i found on CL will work in our cars. i know i will probably have to change out the intakes, but i need an eengine for Deuce. it is cheaper to spend $250 than to pay around $1000 for an engine. i wanna get Deuce going again since Baby is currently in the transmission shop getting her new transmission. she gets to come home on Thursday. Deuce is sitting here wondering when he is gonna get to go out to play. any opinion if these will work, or if i should see if anybody has a Explorer 5.0 on CL?

as far as I know..yes...the intake is the main difference.
but Im not 100% sure...

Is the first one a truck engine as well? The '94 engines most likely have some form of GT40 head, being that they're that new, and the '90 engine should have E7s. Put an HO intake and cam in them and you should have a pretty good setup. Someone with more expertise ought to be able to give you a more confident answer as to whether or not those '94s have GT40 heads or not. Either way, if they're in good shape, it sounds like a good deal to me.

Those are essentially lopo's with E7's. Only 2 trucks came with GT40 heads, the 93-95 F150 Lighting and the 96+ V8 explorers.

yep lopos with e7 heads......swap out to a ho cam and the car intake it will work........shit running motors here are dirt cheap......i just got a 92 cougar ho yesterday

[zwack88]

So trucks have the same cam as the lopo? I thought they were different for some reason.

[88Vic]

So what would be needed to do a HO conversion on a 302 EFI F150, just the HO cam and the HO ECM?

It is different. Same firing order, but different specs.


88vic: yes. camshaft and intake.

One thing you have to watch with truck motors, most of them are not roller engines. Likely the block is compatible, but you'll also need a set of lifters, retainers, and the correct pushrods. These can be salvaged from a dead lopo if you have one.

i have a dead lopo...its in Deuce. i have 3 CVs and 1 has a dead engine because the oil pump went and i drove it 10 miles that way to get home. i just wanna take my intake and slap it on the truck engine. at least i know it wasnt raced like a mustang engine so it should be a good motor. i need to wait and see if he has it next payday. i currently have Baby in the shop for a tranny build so there goes money there. at least when i get Baby back i will have a car w/ a radio since the white one doesnt because the factory amp is dead. i wanna save Deuce from being parted, and i wanna save Baby. the white one is just a beater since it sounds like its on its last leg.

Most any 302 engine will work, however you have to swap intake manifold and exhuaust manifolds and most likely the drive accessories.

Ironically, the "raced" Mustang engines are typically the most healthy.

I wish the 302 in my Lincoln was as clean inside as my Mustang engine was. And the Mustang engine has higher mileage and massively more abuse. It also still has awesome oil pressure.

The HO's are VERY durable little motors.

If you're not planning on swapping the camshaft, you may have issues using your stock ECM with the truck's cam. The trucks used batch fire, and ran a 19 lb injector. The batch fire part doesn't matter really but the bigger lift on the cam plus the increased flow on the heads probably means that it needs that 19 lb injector to run right. The stock ECM is tuned for a 14 lb injector, and likely using it won't run right. If you use the stock ECM and stock 14 lb injectors its probably going to run lean, and using the stock ECM and 19 lb injectors will likely run rich. Ideal solution would be to either re-pin the harness to use the truck's batch fire ECM, or change the cam to the lopo cam so your computer matches. You might be able to get away with 14 lb injectors and increased fuel pressure but no promises.

That said, it wont be hard to swap the cam. You'll need to pull the accessories off your existing engine anyway. While its apart, pull the timing cover and yank the cam out too. You should be using a new water pump and new timing chain anyway so not a big deal. Since the cam is out, I'd personally stuff an HO cam in there. Even if you don't have the correct upper intake, thats an easy swap later. Used HO cam, used 19 lb injectors (or maybe you'll get them with the truck motor) and a used ECM for a Mark VII won't be all that spendy. You can always change out the upper intake and throttle body at some later point for more power. It will run with the stock upper, just won't breathe as well as it could.

HOs are partly more durable because of that firing order. The bearings dont fail like the lopo does. Lots of high mileage HOs, seldom see one with rod knocks or bearing noises. Tons of engines with the 289/302 firing order knock.

OEM's shoot for a MAXIMUM of 80% duty cycle on the injectors in use. This ensures a long and event-free life for the injection system. What this means is that there is typically a fair bit of head-room when it comes to dealing with injector sizing.

The ECM, in open loop, samples the O2's and tries (key word being TRY) to keep from running lean and keeping the A/F inside a pre-set ratio, close to 12.5:1 at WOT. If the injectors have the ABILITY to keep the A/F within that range, the ECM, utilizing pulse-width modulation, will be able to keep it there. Closed loop, the A/F sampling becomes much more precise as the ECM constantly tries to fine-tune it. Injector size and duty cycle becomes much less of an issue here, as the potential "lean" condition will most likely occur at WOT.

An example of this is of course the Mustang guys, many of which who have made 300RWHP using the stock 19lb injectors. That's 110HP more than the injectors were supporting stock. Is it safe? No. Is it wise? No. But it is done. You are going to be trying to support MAYBE 75HP more than the 14's were meant to support stock, that's assuming your engine makes 225HP, and without the HO camshaft, that isn't happening. You can probably get away with running the 14lb/hr injectors if you are running the truck camshaft and it will most likely be just fine until you bite the bullet and do the HO camshaft, at which point the LSC ECM and 19lb'ers will be necessary.

That's my two cents anyways

[Mercracer]

ALL 94+ Small blocks (non Lightning) came with the same camshaft. It is an HO style cam and came in the 302 and 351W motors including the Explorer. We have posted the specs an infinity of times. A little smaller cam than a regular HO but still a good cam. 1.7 rockers will turn them on a bit.
