Wow. Cool. Only 3 days, huh?
The kid I bought my truck from in Wyoming didn't bother painting the frame and it needs it. But I won't bother until I put my 406 in it. At that time, I too, will have to disassemble the truck, and then I'm sure I'll have LOTS of work to do prepping the frame to paint. I might go the POR-15 route. It's expensive stuff, but much easier than sandblasting the whole thing.
I'll be probably installing a 1968 4x4 suspension with 3.73 front and rear axle ratios. It uses the same 8-lug pattern I have now, and I love my chrome wheels. I'd want to keep those.
The only thing is, his transmission with married transfer case has a Chevy V8 bolt pattern, so THAT will be when I have to drop some kind of V8 into it.
I suppose if my 406 isn't ready by then (I need to buy everything...I only have the block), then any old V8 I can get my hands on would do temporarily. Maybe I could look for a TPI 350 out of a late-80's Camaro/Firebird. 24 mpg with better torque than my 235 has.
Please keep posting pics of your project.
