Ok guys, so im currently talking to a guy claiming to have a solid 1974 Blazer. Im not commited to buying it yet, got a few things to work out, but its a definate possibility.

1974 Blazer / SM465 trans / NP208 Tcase (?)/ 3/4 ton axles/ 38in swampers 50% tread / currently daily driveable / has 350 sbc in it currently. Rhino lined interior, camo paint job, $2200.oo

Weve talked, he's sending more pics, and im taking it slow. He's willing to pull the 350 out of it, and sell it for less, cuz im planning on putting the 6.2 in it anyway. and said he thinks he can get it delivered to me, but we need to talk price. otherwise ill take my uncles truck and trailor to pick it up.

So here's my question, I want an NV4500/203/205 setup, how much of a PITA is it to swap from SM465 to a NV4500? i assume the same clutch assembly works, and all that jazz, maybe need to mod the trans crossmember? cut a new hole in the floor? stuff like that? just kinda lookin at what im gonna need to plan for. and im sure its far less of a PITA than swapping from auto to manual.

oh and for the specs, he said an NP208, but im pretty sure its an NP205 (SCORE), and he said 3/4 ton axles, but said it had a D60 front.....
 
here ya go. pic of nv4500with bellhousing/4wd adaptor for 4500/203 range box/doubbler/205.

its from a member here. i think it was a mod on here that had this. and if i recall it was goin in to a blazer.

and fyi thats a cheep price for such a built rig. makes me think somthin is hiddin under all that rino linner stuff. and if all his specs are correct then its a mut truck. best to look at it in person i say. but if you can score it for under 2k shipped then you could make money parting it worst case.

yeah, thats kinda what i told him in not so many words. The price is phenominal, and he said he's had quite a few people try to lowball him for the $1500 range, but with the engine in it, he says he's in no hurry to part with it. So i could probably get it for around $1000-1500 without the engine, and depending on the shipping cost, id be stoked to get it.

BUT i thought the same thing about the price. its not in the rust belt, so thats a plus, but the only pic i got is a very fuzzy cell phone shot. so i asked for a bunch more shots, and even if the shots are ok, ill take a greyhound bus down and visually check it out, take it for a test drive before he pulls the engine, and take it to a shop for a mechanics inspection. and find out what all it may or may not need. Just wanna make sure i dont get another SUPER money pit... cuz we all know these trucks are money pits regardless :rolleyes:
 
as a side note... that trans/tcase combo is a MONSTER, didnt realize it was gonna be such a HUGE B*$&H. well... i knew with the lift and everything id need custom driveshafts. that seals the deal haha.
 
Rene and a few others have swapped NV4500's in place of SM465's.
 
Yeah, that pic is my NV4500/203/205 set-up. The NV4500 is the exact same length as a 700R-4/ Total length on that was 48" from the bell to the rear output of the 205...

Definitely need a rear CV, although I did try a 1410 fixed yoke.

Why not just buy it with the motor in it? Then you have a runner you can sell if problems present themselves? That low of a price if you want it I wouldn't dink around too long
 
FYI, the sm465 clutch setup will not transfer over to a 4500. He 4500 is either internal clutch or a drivers side external. The third option I the AA bellhousing like both Rene and I did.

What he said.

Buy it, drive it home, take the engine out and sell it.
 
talkin things through with the rents tonight, as ill be doin the work in their driveway, then callin the guy tonight. next step is the gray hound bus trip down to drive and look it over.

well, the engine situation is that i do still have the engine out of the camaro. the wiring harness and computer burned up in the fire, but the engine is just fine. figured i could throw a carb and intake on it, and drop that in if need be. so ive got the spare engine... and i have an R code vortec 350 in pieces in the shed. i could probably throw that together and drop it in if need be. last thing i need is another engine to get rid of.

Now, back to the question - so there is an issue with clutch arrangement from the SM465 to the NV4500. and the solution is an AA bellhousing???

what is an AA bellhousing? and would this allow me to use the SM465 clutch setup?

bp71k5 reread my quote to you on the position of the slave for the clutch on a 4500.

and by the looks of the pics its got rusted out front fenders / rightside looks to have a hole in the rocker near the front of the wheel well opening / and rear bumper is screwed or frame twisted or bad body mounts and body is rusted out and dropin on the 1 side.

edit : lookin at the back bumper again the bottom is about dead level with the axle tubes . but the body is droped bad on right rear side.

my personal opinion quick and easy via those pics ( she has been rode hard and put away wet )

did you see the ebay link i posted for your body wanted ad. ?

if you could get that for 1500 and pay around 1000 to ship you would be a lot better off with the californa body and frame.
 
well.... the cali truck isnt running, and has sat for 10 years, which makes me very very wary. nothing kills a car/truck faster than sitting. and the camo truck is currently being driven around. so thats comforting. it also already has some upgrades the cali truck dosnt.

as far as the rust, lets be real, im not gonna find a cheap rust free one. the damage to the drivers front fender was "supposidly" due to a tree branch while offroading. and i saw that spot on the passenger rocker, but forgot to ask him about it. as for the body off to one side, i asked him about that and he said it was parked on a hill, its got a really cheap lift of blocks in rear, and shackles up front for 3in lift, and factory original springs, which im sure are slightly worn out. look at the other pics, it seems to be sitting pretty level to me. but the rear bumper is DEFINATLY tweaked.
 
I'm gonna go out on a limb and go ahead and say this out loud: I'd pass on that and keep looking for something better.

The price for something in that condition is too high. Especially for the age. You can find better rollers (i.e. no motor) for a lot less. Just have to get out and look for them.

I'd bet you could find a better shape rig with little to no rust and no motor for around $500.

Rene, didn't you have a build of this setup once? I seem to think so but can't remember the thread title.
