Duramax swap
So I've got a 2 wheel drive 72 blazer sitting around along with a wrecked 06 2 wheel drive standard cab Duramax,bent the frame.
Curious on the people's ideas on the weight issue,I would think I could swap in some stiffer coil springs to support the massive weight the dmax Allison would add. Would a person really need to box the frame? I've seen many big block and hi horse applications thrown into these rigs without major frame modifications. Whatcha think people's? |

Re: Duramax swap
I would be afraid of the frame twisting up on a 1/2 ton.

Re: Duramax swap
Hp is about 350 and torque is pushing 600 so I guess twist could happen at upper speeds,so we box the frame and possibly add some x bracing.
Pull the tub so we can access all and getter done,it's a plan! The hardest part is jumping in no matter what you do in life but I think this is doable. |

Re: Duramax swap
I’m running a 12v in a 68 C20 chassis, the fronts look identical from half to 3/4. Possibly slightly thicker metal but dimensionally the same. Point is I’m estimating with what I’ve done to be around 325-350 horse and 650-700 ft lbs. power isn’t what will kill the frame, it’s traction/load. Plus our c channel frames flex vs break, but personally something that short I wouldn’t put that much weight up front even though it’s be fun
