Since I don't know what to replace it with, I'm posting here in the 4.6L area since my 95 Thunderbird was originally equipped with one.

I was going to build a late model 4.6L engine but I've sold all of the good stuff I had for that build because I've chosen that I don't want to work on my own car with such a wide engine. For me, it just takes the fun out of it and I'm all about fun when it comes to cars.

This said, I'd be curious on the options. I'm mostly resigned in myself to build a 347 with a Kenne Bell. However, the pill I'm finding tough to swallow is the iron block part of it. The original 4.6L was iron block alumn. heads, but I really appreciated the upgrade of an all aluminum engine with the DOHC swap. That goes away with the 347ci.

The other option is a new Coyote 302 engine. This seems to be a more narrow DOHC engine and there is gonna be plenty of them to go around... I just don't know if it is going to be narrow enough to make a difference from the 4.6L DOHC.

Any thoughts (please don't bother with the "what's a cooler engine". I agree the coyote is far more cool... BUT if its gonna be a nuckle buster like the 4.6 than its not worth it.

That high powered 5.0 stuff is cool but its not going to be easy with that year of bird. You should get a 5.0 bird if you want a 5.0 based engine. Just saying :D

World products does make aluminum 302 and 351 blocks, so if you have a spare $6K, you could pick one of those up.

Yeah, that's exactly why I don't want to go the route of an alumn block if I go the direction of the 302, or the 351 for that matter.

Unless you got $12k plus, the coyote is not an option
Yeah, I know the coyote isn't cheap now, but that's because its brand new. In a couple of few years it isn't going to be as bad. Kind of like the LS GM engines. They're rediculas reasonable now, I mean you can get a while car with an LS1 for under a grand. Generally you score that, you can part a remainder of the car out and break even - thus getting the LS for $0

I was pretty certain there was only a 3" difference between the 4.6L DOHC and the new 5.0L DOHC. I know that little bit can make a difference, but I don't think enough.

I can't walk away from the one I have. It has the interior I like and I have already started body mods and suspension upgrades. I know a lot of that can be converted over, but then I'd have to swap interiors... I think I'd just be trading one pain in the *** for another.

If the earlier birds came with a 5.0 I'm not following why getting one in a 95 would be that difficult? I haven't looked at the details on that swap, but why wouldn't it be factory parts to get the engine in (i.e. engine mounts for example)?

With a twin screwed 347 a factory 302 block won't last long. They do make aluminum blocks for them though.
See, I need to look into this kind of stuff too. I'm sure there are aftermarket blocks (alumn, and iron alike)... if I go with a 302 I'd have to see what's out there.

I don't know if the factory 351 has any better chance... perhaps a lightning motor... I don't know if those were DOHC engines or not, I'm suspect that they are.

I like being able to get a late model 302 from an explorer to start with... funny thing is, I wait like, what, 3 years here in MD and I'll be able to put historic tags on it so emmissions will not be a concern to worry about whether its an OBII 302 donor car or not. I need to do some research and see what engines ford has to choose from between the years of like 89 to 99 or something like that.

First gen Lightning motors are just GT40 HCI equipped roller 351 windsors. Second gens were just 5.4 2Vs with a blower.

If I were to go 302 based I'd look into the Ford racing offerings, they have a broad selection of strong blocks these days. Otherwise a factory 351W will handle just about anything you'd want to throw at it.

Anyone ever drop a Cleveland in these cars or any other 335 series motor? That would be cool.

There's a few but it's really not worth these days. The only ones any good were made in a 4 year period and the modified series are bigger boat anchors than the 5.4 2V. The Windsor just has so much more modern go fast parts available, the Cleveland parts are scarce and expensive and really not much good unless your doing a period restoration.

My friend had a Diamond Jubilee Thunderbird (76 I think) with the 351C and a 2 barrel. That thing was a dog. I think it ran 18-19s in the quarter. I have also heard you can change the rods and crank and make it into a 400M, but he never did it.

A supercharged 5.4L 2V would be great, but with overhead cams its probably exactly like having the original 4.6L SOHC engine, as far as footprint is concerned.

If I was gonna do that though, I should have just kept everything I just sold. I think I need to go with a pushrod engine. The first gen Lightning 351 for a 1995 is most likely what I'm gonna need to go with.

Anyone have any clue what other cars were equipped with the 1st gen lightning engine - and are there "better" and "worse" ones to look for or stay away from?
It sucks... I noticed Kenne Bell doesn't offer a supercharger for a 1st gen lightning.
