I searched so :flipoff2:. Ha ha.

I'm going to be building a racer to run in the SCORE and VORRA races. I'd like to run an EB but I think that it's tough to get around the wheelbase advantage of a big Bronco.

So what's the wheelbase on a late 70's BB? Also, did they ever come with a big block stock??

You can stretch them quite a bit, too... My '90 is already about 107", and it's going to be 109 or so once I'm done moving the rear axle.

And no, only the 351M and 400.
Yup, and a little more history for your enjoyment here.

*edit* nice fellow here on this board by the name of jca that has
some racing/big bronco experience that may be able to answer
more ? you may have.

Hopefully he doesn't mind me pimpin' his knowledge. :beer:

Thanks for the info! You can only extend the wheelbase by 2" in Class 3...

I have my Early Bronco RockCrawler @ about 100" right now. Should be real nice on and offroad. I'd only be able to do 94" for a Baja racer.

As to how much lift... start your own thread, don't take over mine!

as stated above they came with a M block. but they do however have a bigblock bolt pattern on the tranny. This makes swapping to a BB easier.

When doing motor swaps you are restricted to the same family as what was available stock. So you can put in a 351W in an EB since it was available with a 302W stock.
