What a great job, reminds me of a guy that was building his own boat a he had a big Gardner 6L3 diesel (114 hp @ 800rpm) outside on a stand, when he got frusterated with the boatbuilding he would just go outside and start up that beautiful big engine and just watch and listen then get back to work

Absolutely Beautiful thank you for keeping the old iron working - my Dad hauled gas for the 474 fighter group in ww 2 the stories he told about what they put them engine’s through would amaze you - including the stuff they did to get the job done, like crossing a very deep ravine no bridge they laid two big cables across put there spare tires on the front axle so all the wheels had duels - drove across the ravine with the cables between the rims - Dad said it was deep enough that if something went wrong there wouldn’t be anything to salvage - the balls it took to drive across that - Truly a special generation - thank you again

@jeffbell6211 3 жыл бұрын

The 302 and the other engines in this series (228 ,248 , 270) were several years earlier than the 230 250 292 series. They do make speed parts for these including a supercharger manifold for a 6 71

@Slim_Slid 3 жыл бұрын

The GMC 302 was used in the GMC M135-M211 2 1/2 Ton Military trucks,which were the first that used 1100×20 single tires,even on the rear,and that had automatic transmissions.All of them got sent to Canada however,because the M35 2 1/2 Ton was what America went with,using non directional tires and a Spicer 3053A and was also a gas truck as well before using a Multi-Fuel engine.Before the two of them,there was the GMC 352-353 CCKW that used a 95 HP GMC 270.The 250 and 292 were used in G.M. trucks years later,and then there was also a 261 which was a bored out 235 basically.The 292 was one of the gasoline engines that even the Chevrolet C60-C70 used as well,the others were the 350,366,427,and even 454,including some with a Detroit 4-53,6V-53,and 3-71,adding the 8.2L in later years.

@jeffbell6211 4 жыл бұрын

It would be different to be sure , but they don't have near the HP of a Coyote and they're really heavy too. These engines go way back when flatheads were only 85 -100 HP these big sixes had 160 . Guys coming home from WW2 could get them surplus for cheap and then put them in Model A's like I'm doing. There are still several Bonneville racers using the same engine in XO and XXO class going over 200mph

@jeffbell6211 3 жыл бұрын

@Russell Gerdes They have been racing the GMC inlines since the early 50's , maybe earlier.There is a vintage engine class in the SCTA that these inlines fit into and they are still competitive setting records at Bonneville and Muroc at over 200MPH. It is common for builders to bore these .125 over and still be reliable. The Chevy's are pushing the limit at .060. Condolences for your brother , thanks for the comment!

4 inch bore X 4 inch stroke, totally badass. Guys were dominant for a period of time after WW2 racing with these. So they started banning "truck engines" at more and more tracks. That was done to stop people from using the GMC 302 (even the 270 I suppose)

Are you talking about the 600 plus inch V12 with the plaid valve covers that kind of look like 409 covers?....So cool! but very heavy , It would be something in a big speedster like the 'Blastolene" car...I'd take one! Thanks for the kind words!

@Slim_Slid 3 жыл бұрын

The "twin six" you are thinking about is actually the GMC 702 V12,which is two GMC 351's put into one engine block,and it is actually 11.5L,not 9.5L.Those V12's were used in tracked howitzers at one time such as the M109 Paladin,the other tanks like the M60-M60A3 Patton main battle tank and M88-M88A2 ARV tank retriever had V12's too but they were made by Continental and both were petroleum and diesel,the ones with compression engines came out in 1964.They were 1,790 cubic inches,not 702 cubic inches like the 11.5L V12. The GMC V12 was also popular among many fire trucks,not just G.M. trucks and other apparatus in correlation.The other V12 that fire trucks had was the A.L.F. V12 that American La France Series 700-900 fire trucks used,before they went to using Detroits and Cummins in 1966.The other engines they had was a Continental R330-R883.
