    Sticky in the engine/drivetrain forum....

    For the code for your blazer, just look in your glove box and they should be listed in there...

    Dont the older trucks have fuel cut offs like the newer ones?
    My truck cuts off at 96 or so. I had it bouncing off the cut off last weekend.

    Mine wont go over 80 or so. Thats because I wont let it. It feels like its going to shake apart. I have hard that the 4.3s can hit about 120mph.

    no i'm pretty sure my blazer was doin waaaaaaay more than 96. err i mean hypothetically it was :rofl: i have a 97 s-10 and it wouldn't touch the blazer in a high speed race, speed limiter sucks.

    speed

    my blazer is a beefed up 4.3 and the speedo only goes to 80, so i wanted to see what it could do on the freeway. so i got a rolling start and layed it to the floor. my speedo hit 80 but the truck kept going and the gauge was just bouncing. these 4.3's haul ass for a small block. i'm either putting a 355 for sure or a 396 if i can fit it because the block is the same size just the bore and stroke are different. then ill be doing donuts around the gay tuners at my school. oh wait i already can. faggot ricers

    I beat most people with my blaze. Its got 4.11s in it so its quick off the line, but top end it kind of dies out. Light to light racing is fine, but highway......forget it!
