I've got the scanned brochure for 1995 (thanks to KargoMaster) which of course will reflect combos that include a throttle body 7.4, not Vortec.  Payload ratings:
6.5TD 9,347
7.4 8,098

I would imagine that figure is assuming bare-bones cab & chassis as any bed upfitting would be included in the payload figure.  Dunno?

I think the difference in payload ratings may be due standard diff ratio, 4.63 with the 7.4, 5.13 with the 6.5TD.

I think the trailering capacity proves that point, too.  GCWR ratings with automatic trans:
6.5TD and 4.63 16,000
6.5TD and 5.13 17,000
7.4 and either gearset 19,000

With standard trans:
6.5TD either gearset 15,000
7.4 either gearset 19,000

Since GCWR is obviously dependent on the weight of the tow vehicle...you'll need that info to figure trailering capacity for a particular rig.

Looks like if you want to carry heavy payloads, best bet is the 6.5TD with 5.13's; best bet for heavy trailered loads, 7.4 with either transmission and either gearset. :D

Wish I had the Vortec 7.4 figures to compare.

Or I misunderstood your question...?

Nope you got me just what i wanted to know, tho i am also wondering what the 7.4 Vortec ratings are . . . There ain't NO WAY i would ever get the 6.5-TD, i already own one and i can safely say the 454-TBI & 454-Vortec will run circles around it  ;)

454 / 5spd / 4.63 or 5.13 shortie with a flat bed, basically i would like to get a 3500HD 454 5spd with an 8ft flat bed  ;D

I like the Sawed off shot gun effect  :o

You're describing my truck, other than the flat bed part.  :D

Vortec 7.4 (swapped in for 6.5TD, complete engine, harness, interior swapout), NV4500, 4.63's, 135.5" wheelbase.

mine sounding like yalls trucks 94 6.5 converted to 97 7.4 vortec 97 interior but mine is 165wb and will be a dumpbed. By the way Richard your pic have been a hell of a big help on my tear apart and rebuild so far I cant wait to get my truck done. I cant decide on the paint color yet, either Red, Black, or Silver dunno not white there is too many around, that 's the color it is now with some galva showing through   
Life is what happens while your busy makeing other plans.

RED ;D is my Vote ;)

I love my 62' GMC K3000 = Modern 4500, but visually she looks like a 3500HD . . . stand pickup cab with heavy axles n 19.5's . . . I can't wait to own a more modern version the 3500HD's you guys have  :o

They ride about the same. ;)  The only difference stock-for-stock is the newer ones steer, accelerate, and brake better...and have A/C. :D

 :o What makes ya think i ain't got A/C ;) . . . Ya must have missed the 24/7 A/C holes :'(

Stop better sure, Steer better ? ya mean easier ?, accelerate better ? ha i bet my 48+ year old Gasser would give them 6.5's a run for there money in a 0-65mph race . . .

I bet parts are easier to come by, tires can be had easier, and ya don't looks as poor to ;)

 ;D Tho i still think the 62' is less likely to break  8)

You wouldn't catch me buying a 6.5 so that part of the argument is invalid. :D  I think my 7.4 could whup the '62 even if I was towing another '62 like it on the hook. ;) ;)

OK, enough bench racing, go get you a "modern" HD!

 ;D I wouldn't be too certain about that i did whip an 87 Z28 from 0-45 on night tho speed limit was only 35 :o I walked him all the way from one green light to the red light at the next intersection  ;)

Its nothing special tho just a 48 year old dually, with a GMC-379Ci V-6: 4.562" Bore 3.861" stroke 6 cylinder's, 170N-hp@3,400rpm & 366N-tq@1,800rpm <- stock, SM-420 4spd and 5.14 gears, and 8-19.5 traction tires . . . I know it would whup any 6.5-Turbo out there in the same sized truck  ;) the 7.4 Vortec has me i'm sure no doubts the 454TBI might be tight but i think it would have the win too . . . 6.5-Turbo never happen  ;D

Tho currently is bord .030 over and the 7.8:1 C/R is now a 8.6:1 C/R and it has the newer Big Block V6 Magnum head's and lil'2bbl swapped for Big 500cfm 2bbl, So it might be a bit more peppy then GM had intended it to be but i bought it that way only 36K miles on engine to date ;) . . .

EDIT:
My guess is it's in the 190-210hp & 390-410tq ??? range with the PO's mods done, Still 170hp & 366tq from a stock V-6 ain't bad ;D

I think I can outrun a 6.5 on my bicycle. :D Unless it's in its natural habitat - on the back of a wrecker...

You would think with all this demand for Big power and high MPG's GM would build a modernized version of those Big Block V-6's ? . . . They had industry leading power & MPG's back then for almost 2 decades . . . 1960-1974 . . .

305Ci, 351Ci, 379Ci, 401Ci, 432Ci, and 478Ci all of them V-6's plus they had the 292 & 302 I-6's the 637 V8 and the 702 V-12  :o and a few of those were Diesel's in the 1950's, convert large displacement diesel into Gasser = long life span they advertised them as going 200,000 miles without needing an over haul  ;)

I've wanted one of those 637's since I saw it in a manual at the library.  I've never seen one, though........ not even online.

I believe you have the lineage backwards......... it's my understanding that the gas engines came first, then were dieselized.  The Detroit Diesel fans generally think the Toro-Flows are junk.
