Swap a straight six back into a V8 convert 73?

Anybody go back or go to a straight six from a v8? I'm thinking of going to a 300 six cyl, someone dropped in a 351 V8, any thoughts? That or a 302 v8...

I'm not sure about the 300, but the EB's that came factory with a 170/200 I6 had the engine mounts moved forward on the frame a couple inches. I believe that they stuck out from the frame a bit further for the narrower engine.

Although I've been told the latter model trucks with the 300 can be swapped to a 302 rather easily. The 300 block may have close to the 302 dimensions.

Why do you know the truck's engine was swapped? Even it it was I don't think anybody sells the frame towers for sixes.

300 sixes are a lot larger than 170/200 sixe. They probably will not fit in a Bronco's engine compartment.

Good friend of mine had them for years in Pickups.

Why bother... they actually get worse gas mileage than V-8s.

One reason would be that the 300 makes peak torque around 2000 rpm's, if your into wheeling, it doesn't get much better than that unless it's a diesel.
