Its still gonna be heavy even if you cut it shorter.
The t-case will still be a slip yoke if the truck is '80 or newer. And if its a K30 up to '84, the 465 tranny will still have 10 splines. '85 and newer K30's have 32 spline and slip yokes again. Would either have to replace that with a fixed yoke or find a whole replacement t-case.
I'd still prefer a SWB truck for the weight. And IMO, its gonna flex better than the K30 frame, too, since its not as tall a frame as the K30 is.
You're right. Blazer bodies are too long and heavy and fight the fame flex, which hurts both, but may or may not be relevant depending on the cage. I will prolly end up building a CUCV for the reasons I mentioned...I intend to have a 500 cid Caddy to help with the weight

I think the truck should be affordably done and practical. Here's my brother's.
Carbed 305, intake, exhaust. Built TH350, F*RD NP208 slip yoke. HP F*ORD 60, ARB, 4.56. 14BFF, Detroit, 4.56. F-150 rear springs, Tahoe rears in the front. The truck is light, stripped interior, one gas tank moved to the bed, no winch or cage, racing buckets. 11.00x16.00 XLs. No bed floor, and the stepside is almost like a narrowed bed. It works very well, even with the little 305, climbs dunes. He intends to finish his doubler with F*RD 205, cage is in the works, and engine choice is up in the air. He's thinking about mogs now too... He gets half his flex from his frame, but it is eventually going to get tired and break...this is where the 1/2 ton vs 1 ton frame question comes into play. If you go 1/2 ton you get flex and light weight, unless you add a cage, in which case you become heavier, but stronger. Probably the ideal setup. I'll probably use the 1 ton frame cuz the wheelbase fits what I intend to do.
In my opinion, and to the extent of my knowledge, the best bang for the buck when it comes to a building platform is a CUCV (or diesel K30). Can be had for cheap, body is usually OK, but doesn't matter, grill guard and tow points if you like, and can be run diesel or gas with no smog problems. Already has 4.56 gears and one locker. Combine with XLs (siped?), standard chevy beefup stuff (Xover, steering bracing, flexy leaves, etc.) and a front Traction Aiding Device, and you're golden. Only downside I see is the Tcase, but that depends on your engine, your right foot, and your terrain. Also can double as a work/tow rig, which is part of the reason I want to use one. Wheelbase helps with DL angles too...
Noticed this K30 flex pic when I was looking for a pic of my brother's truck. Appears to have some frame flex
EDIT: I prefer auto cuz a stick is pretty useless duning.
PS This thread is AWESOME. I've been waiting for/wanting to start a build theory thread. COG material?
