Evening all

Looking for a little advise and have read some of the information on the forum. While I am well versed in twisting the odd wrench and fabbing stuff I am out of my element on the stovebolts.

I have a 1949 "3804" single wheel 9'box.

I am wanting to wind up with a very drivable vehicle capable of hiway (60mph) speeds reliably with a small camper and I can't see the old 216 being up to the job even modified.

I expect to use the stock trans but change the rear axle ratio to keep rpms in the 2500-2700rpms range.

But I want to keep an inline 6, make the minimal change possible to keep it looking as original as possible.

I was considering a 235 but I don't think it will do it. Thoughts?

Maybe a full oil pressure 261 with modifications? But all the 6 swaps seem to concentrate on the 235 and I am not clear on the difference in the swap.

The real big GMC's are too hard to find or get parts for in my part of the world.

Suggestions?

Tom
