How hard would it be to swap a early 354-392 Hemi in to a 1980-1991 Bronco?

Thanks

If you have to ask this question, it's going to be really hard.

Do you weld? Do weld well? Do weld 1/4" thickness steel well?

Are your investments yielding in such a fashion as to provide a steady stream of cash well in excess of your needs?

Are you good at fabrication?

Are you going to run the stock engine or is it sporting a 6-71?

Are you just repowering or are you building a racer?

Do you have access to hoists, jacks, clean & safe place to work?

 

I weld.

I weld O.K.

If I did it I would borrow a better welder and a freind who welds better.

I am good at fab and "redneck engineering" and know people who could help.

It would be a stock rebuilt 392.

It would be a neat street cruiser with the occasional mud bog.

I am pretty much looking for ideas.

 

Do you have a stock rebuilt 392 Chrysler Hemi from the 1950s?

 

I do not. I am intending to find one and do the swap when time and funds allow. I'm not expecting this to be cheap or easy either.

 

Well, it won't be cheap or easy. A lot of 354s and 392s got used up drag racing. Remaining units are prized by the restoration crowd. You can find an air raid siren with a 331 in it, but good luck making power with that.

These babys, even the 331, weigh over 700 lbs. The highest stock hp for the 392 with 2 4bbl was 390 horse, gross hp and so that translates to about 312 hp net.

If you build it stock--what's the point? If you are going to take advantage of that 700lbs and make a fire breather, well, shall we say, more power to you.

You'll be on the road faster, going faster, with a fatter wallet, if you build a 400 with a straight up cam, some compression and a decent intake and headers.

Good luck.

 

Thanks for the info I will take that into consederation. I might go with a 440 Mopar.

 

Funny thing is, i know where there is an almost complete 331 hemi and a Complete 50's Dodge truck hemi siting in the woods. i wish I could have them. I doubt the owner would hook me up.

 

All you can do is ask. You already got the 'stang!

 

why not just a 460/429 or FE.

 

I will probably end up doing that. I might swap in 352 though, because a buddy of mine has 2 that I could get for cheap.

 

A stock 352? All that work--not a stock motor, no no no.

 

How about a 347 stroker? Would that make everyone happy? At least I didn't sugest a SBC! Oh and one of the 352's is all worked over bottom end, cam, heads,intake etc.

 

What's in the beast now?

 

Nothing. I know a guy that beats them to death in the mud, takes the engine/trans. out then leaves them to rot.
