Also, just so ya know i aint blowin smoke...

for whatever reason, I cannot see the pic. what is it?

I'm not wanting a stupid fast street racer, just a stronger motor than before. 4.6's are way more available than the 5.o explorers. that's all.i can get a 5.0 out of a t-bird. can get the whole car running for about 500 bucks. expos go for twice or triple that around here.

Just be prepared if you get a 5.0 out of anything else other than a expo plan on shortening up the front engine accessories. The expo 5.0 has custom brackets from the factory to make it shorter. The 4.6 is a great option but I have not seen one without deleting the a/c. I did see one with the heater still working.

Stock for stock a 4.6 is the same physical size as a 460, requires more wireing, and makes less HP and waaaay less torque, and pry weighs close to the same.

The 289 was actually enlarged to 302 cubic inches for SCCA(?) Racing. They had a 302 (or 305, dont remember which)limit on engine displacement, same reason chevy made the 302, and chrysler had one in that range to. IIRC vehicles were unchoked completly untill model year 72.

The Boss 302 was made for SCCA racing and is almost a different engine from a regular 302. The plain 302 was developed for the same reason the 289 was... mo powa

Hmm, i stand corrected on weight

could these brackets be fab'd or bought?

281, none of that GM crap...

All the 4.6 swaps I have seen are on stock height 2wd trucks. They had a factory "full to the brim" appearing engine bay and really didn't look too bad.

any thread links or additional info on these builds would be AWSOME

A 4.6L weighs nothing close to a 460 big block, in fact a 4.6L weight less than a 302.

It has a similar size on the outer dimensions, but the block uses a lot less material, and the heads are aluminum, that cuts a lot of weight. If the 4.6 had been done on a smaller V it could have been the same size, or a little smaller, than a 302.

But it wasnt. So you still have to do the same amount of chopping to get a 460 in, just run 3/4 ton front springs.

Not to mention even your weezing 70s 460s were making 365ftlbs, to my knowledge no garden variety 4.6 even comes close. Not to mention you can build a fire breather alot cheaper and eaiser with a 460.

Good, if you wanted stupid fast the LS engines are better.

The 460 is longer though, in a tight RBV engine bay length gets tight faster than width. Coupled with the weight I would pass on a BBF.

Still shorter then a 300 I6.

Either way, for the OP, just go 302

Yeah but if you don't move your firewall back 300-6 leaves you 2 inches to put fans, radiators, and any other coolers you may need in the engine bay.
