Finally the cat is out of the bag.
I'm very excited to see this project start also.

I agree the 300 output is a weak link and should be upgraded asap with V8.

I'm confident Marks driving style can and will be fine with the 44. Especially with RCV's.  It's all about Finess.

We had similar Dana 44 - V8 shaft breakage issues in competition , But these were Extreme rock crawling competition situations on mostly on Spraycrete.
Most major failures early on were shitty u joints and stock shafts.

However i do recall asking why not go with the 60 - 14?

Housing weight, length and diff size (length and belly).  Also only running 36-37" tires.  Short wheel base makes inches valuable.

I only had 3 axle breaks in 9 years - all due to u-joint failures in binding situations with my D44/360 combo on 36" tires. Granted, I don't have a heavy food, but neither does Mark.
Chromo & RCV's should be golden.

Looks like it's going to be a sweet build!

i have broken (5) 4130 60 shafts, (2) delco 60 joints, (2) spicer joints, and (1) 4130 60 RCV


i would run the best you can afford, i spent about $6K on axle shafts last year alone....

I'm sure you remember how well my 44 went.

I stand by it being a waste of good money to bling a 44. There are better options for the 2500 you're going to have into a balljoint, small ring gear, still not that light, thing.

We have different driving styles, but D60 was probably the best upgrade I've ever done. Maybe something less with RCVs would have worked, but meh.

I am super excited to watch progress on this build!! Super cool.

Nice stance but too buggy-esque for me.  No dovetail, a real windshield and fenders, lower roof line (if possible).

Any concern about the driveline length?

Very much.  Trans and t-case options get limited fast.  4L60E and TH350 are the shortest auto trans and D300 or Atlas are the shortest possible gear cases.  Won't be anywhere near the original combo of T90/D18 length.  The rear stretch of 3-4" should keep rear shaft around 24"?

oil pan belly to top of truck manifold is also a large dimention.  If the car is small and tight, you should consider options for changing to lower profile top or bottom ends, or both.  they are massive.

Interweb says the thing to do is an LS1 or LS6 intake.  Or ginormous hood scoop!

I think Arie is commenting on your parentage. Most likely in a not-so-nice manner.
