The Stovebolt Site Forums The Parking Lot Big Bolts 49 GMC parts

Hi...I am new here,and there seems to be lots of info availible here.I just recently picked up a 49 GMC 1 1/2 ton,at least I think it is a 1 1/2 ton.Is there any place that brake parts are still availible? I am planning a SBC transplant as the engine is long gone,but I may use the original trans or go with a turbo 400.Are these logical for a transplant? Also is there a way to upgrade to disk brakes on the front? I may be asking questions you guys have heard a million times,and if so I appoliguise.But any help is greatly appreciated!!! Thanks!!! Eddie

just a reminder that a turbo 400 dosn't have provisions for pto that's what keept the 4spd in my 44 grain truck

Mine did not have a pto.It does still have the original SM420 4spd,but the engine is long gone.I was thinking a 283 or 327 with a turbo 400 would work ok.I do not think the truck would be doing any more heavy hauling,so the 400 should be strong enough??? Thanx!!!

I've never seen any evidence of a disk brake conversion for these. I've thought about adapting disks to one, but its going to be a challenge to figure out what disks, bearings and calipers to use. Please let us know if you solve that one...

I saw a '51 Chevy 4100 at a car show this weekend that has a 383 (stroker small block) and the SM420. It also has a 3-speed brownie that allows it to run 70 on the freeway.

I'd sure what to be sure my brakes were good before trying that!

Anyway, the owner said that even with the stroker motor he was disapointed at the performance when loaded, because the motor does not have the torque he wants.

I wonder if an axle out of a newer 1 1/2 ton truck could be fabbed in???

The stroker is more of a rpm engine than a torque engine.And it has a lot to do with what it has for guts.It just has to be built right.That stroker would be much better off in a 1/2 ton PU.

I think you'll find they are too wide, but I've not measured any.

I called it a 383, but I may have gotten that wrong, it may be the long stroke 350 instead of the short stoke 400. Talking to the guy I think what he really needs is a 572 with an automatic.

Were there any 1 1/2 ton 4x4 trucks??? A 4x4 axle with disks would be nice too.

Somewhere,somehow it could be done/has been done.But as long as I can get the brakes going,and working ok,the drums will work.

A 454/turbo 400 combo would be nice too.

some army trucks had all wheel drive I believe

Some military trucks had 4x4 in the larger versions. A company called Campbell (I think) made a conversion kit for the larger trucks, just as NAPCO did for the lighter-duty trucks, but I've only seen one, it was on an old phone compnay COE that sold on eBay several years ago.

Hey Ramblin, Try, these two places, for your brake parts, Alretta Truck Parts (ask for Geoff) (508) 788-9409, or Brake & Equipment Warehouse (800)523-4632. You need to have your correct truck spec. info., so knowing, if you have a '49 GMC 1 1/4, 1 1/2, or 2 ton truck, is important. What does the ID Plate, in the driver door jamb, say.

Just swap chassis's, that's what I did.
I have a 49 1.5 ton cab and hood with 49 2 or 2.5 ton fenders, on an 89 1 ton 4x4 chassis with a 454/t400/np205 dana 60 front 14 bolt rear.

I just drove it from San Francisco to Flint Michigan in 5 days.

Everyone LOVES this truck.

Spanky....it is an FC-301...1 1/2 ton?

49gmc.....I have been thinking about that.I would like to keep it a 1 1/2 ton,but a 1 ton would be ok too.I just need to get a title for it.It had no title when I bought it,sitting a longggg time! And I would hate to use a later model title,all the Calif smog BS!!

Ramblin, I discovered that the king Pins in your truck are the same used all the way to 1980. My front brakes/backing plates/Spindles are from a 1980 Chev C50 with the 5000# front axles. Works great and drums, shoes, and hardware are all readily available for the C50
