I have a 1990 Chevy Blazer. 7 inches of lift and 38inch tall TSL tires. I want to rebuild it but what do I need to shop for in the way of cam and piston? I have built a couple of Drag motors but this needs low end. I plan on using the upgraded stock TBI system.

check out summitracing.com….you need low end torque for off road…. a stroker 383 would be good….keep the cam duration below 280 degrees…
Find a 350 you are willing to make into a 383 stroker. Kits are available anywhere, and not to pricey. The gears are what will make the best difference for you. Stock gears in those were 2:73 gears and if you have put 38″ tires on then your ratio is really whack and you have virtually no power. Good Luck. ( I have an 89 with 8″ and 44″ mickeys)
I would go with a 350 and buy a kit to make it into a 383 stroker
you can get more low end tourque from the 4.3 engine that comes in most blazers i have a 98 and i put headers and bigger trhritle body from a 350 and got much more low end power than my 88 350 tbi with headers and 3/4 racing cam and roller rockers
