Help me decide what to do !

[Spray-Bomb]

Ok guys, I can't decide what to do with my truck

I know I want it to be a SWB & I'm gonna bag it to go really low

So do I put it on a SWB frame, of which I own or cut down my LWB frame ???
I'm gonna build the frame from the cab back, so I dunno which would be better

Do I put a later A/C cab on & call it a 67 with the Panoramic View option (I like the small back window cuz 67 was the only year for it, but I like odd factory options too) ???

What kind of engine, 5.3 with 4L60E & computer... or a fairly hot SBC

And the last thing is: Do I just sell my truck and build a new one... I have a short wide bed & a A/C cab from my dads 72 that he said I can use & I have my SWB frame to put it on & I have a 700r4, then all I have to come up with is a front clip (if I were to sell my truck I'd put a different engine & exhaust on it)

I have Kilroy to drive while I work on my black truck, so time consumption isn't too big of a problem
