Hey guys I need another small block to throw in my 79 F-150 while I put together my 429ci. I found a lincoln 302ci (sequential fuel injection) with 58k original miles. Its clean w/o any leaks, looks to be all original gaskets/etc. I've got an Edelbrock intake/street avenger laying around here i can throw on it but my question is, what are the specs of this engine? Roller cam? Heads? I don't know much about the Lincoln windsor engine. Any opinions on it? Thanks fellas!

 

If it's a coupe then that is the HO and yeah it's worth snagging(it's also worth getting the complete engine harness, EEC, MAF meter, airbox and tubing), but if it's a towncar then that is the lopo 5.0 with the worst SBF heads ever produced and the puny cam that makes all of 150hp.

 

Yea the engine is an HO. So what heads/etc does it have? I can get a set of GT40s I could have redone and throw on it unless the ones on it are GT40 or something decent. As I said earlier I haven't dealt much with SBF...

 

Scratch that. Spoke to the guy with the engine and he doesn't know if the plenum (which is now long gone) said H.O. or not... Is there another way to tell the difference between the two? Block numbers? I do remember it having what looked like shorty headers but were factory ford... Don't know if that helps - probably not lol. If theres anything I can check on that will help you help me just let me know and I'll stop on my way home from work in the morning and check it out. Thanks!

 

I don't suppose you can check the firing order? The 302 HO has the same firing order as the 351W, while the 302 lopo has the regular SBF firing order. I don't remember what they were off the top of my head.

 

I think if it has MA and SFI its an HO , like xlt said it will have the 351 FO if its an HO , if the intake is off you will see the roller cam....

 

1984/89 Lincoln Continental Mark VII: There were two different 302 engines. Only the Mark VII LSC has the 302 HO, same as used in Mustang's.

351W's were not installed in Mark VII's. Only the 1980 Lincoln Town Car & Continental Mark VI came w/a 351W. The 351W was not available in any Lincoln after 1980.

The only other available engine in a Mark VII was offered in 1984 only: BMW 2.4L 4 cylinder Turbo DIESEL.

 

Thanks guys. I took a chance and and bought it on my way home this morning. After I unloaded it i checked the firing order as I tore it down and of course it had the 302 firing order so i'm assuming its non-HO. Being that I already bought it, I might as well make due. - What do I need to pick up to make this thing half decent? As I said earlier I can get a set of GT40 heads fairly cheap if they are what he says they are. If not, what vehicles can I find em on? (<---I'll research this in the meantime.) The cam was mentioned earlier so I assume it will need swapped out as well. Any suggestions on it? I'm all ears fellas. Thanks again.

 

The bottom end of the motor is as good as any so you have a solid platform to build upon. There could be several different heads on it but GT40's are better then all of them so I'd suggest you go ahead and get then ready. You can determine a lot about what motor you have by simply measuring the cam lobe lift, if you get about 0.275" and it's a roller cam you have a HO grind, if it's significantly less or a flat tappet then it's junk and there are lots of aftermarket choices that will produce lots more power. If the motor has flat top pistons you are limited to about 0.500" lift and maybe 280 deg total duration, but considering this is going in a truck you should target a 260 deg grind at most so the motor has at least some low end grunt.

 

If the pistons are flat top then your will pick up a bit of compression with the GT40 heads over the stock heads. That's a good thing.

 

Ok according to the number on the heads I mentioned earlier they are NOT GT40 heads - they are E7s. So what year explorer/mountaineers came with the GT40s? Also whats the difference between a GT40 and a GT40p? I assume from what I've read GT40s are more desirable? Paul, I heard you mention in another post that heads and cam from a 94+ model are a significant improvement for this engine. This is a little off-topic but I'm trying to learn as much as I can - What is different on the 94+ trucks from the pre-94 model? Thanks again fellas!

 

gt40p is the newer head. It has no previsions on the back of the head for the air pump to hook to. It also has 90* plugs. regular exhaust manifolds, or headers for f or e series trucks will not work. There is a stainless steel header available, they cost around $400.

 

E7s are the stock head used on all regular 5.0 and 5.8 motors from 1987 on including the 5.0HO and they aren't the worst thing in the world. GT40s were found on '96 to '97.5 Explorer and Mountaineer and the Gen1 Lightning 5.8 so they're actually a little harder to find than the P version.

The only thing that changed on the '94+ truck motors is the cam and it was a significant change for the better but even so just about any aftermarket cam you can buy will produce more power.. particularly with a carbed motor.

 

Ok good deal. So if I go pull the heads off my old 96 sitting in the field (E7) and put em on this thing along with an aftermarket cam how much hp/tq am I sacrificing by not using the GT40 heads? Only reason I ask is because a 10-25hp loss isn't going to be an issue for my purposes.

 

GT40 heads are probably worth 25-30hp over E7s all else being equal and with the right cam a stock 302(with E7s) can make 275-280hp. Use something like a Comp 35-234-3 for a flat tappet block or the Comp 35-410-8 with a roller block.
