    It does look cool how it slowly appears to start spinning the other direction.

    Here you go, I published an exhaust video and included the burnout clip in it - for those interested.

    TBI 383? Which one? I’m intrigued. Thanks for feedback on the shifting. Looks like I’m not alone.

    I'm pissed, my Blazer won't even think about lighting them up. 3.42 gears and 33's , go figure. I looked up my RPO code yesterday and it says GT4 which…I think means I have 3.73 gears. It spun both tires, as you see in pic above. This truck is still original and bone stock, except for muffler...

    Longest I’ve done since high school 20 years ago! I baby this truck, but I work with a bunch of gear-heads (like me) and Monday night after the annual work party everybody got in the mood and started smoking the tires on their Chevys. It was fun. I cheered them on, but I didn’t join. Since that...

    The truck runs/drives/shifts perfectly…before and after the burnout.

    Hello, I caved to peer pressure this week after work and did a burnout in my 1994 Z71. My truck is: 5.7 TBI, auto trans, 4x4, extra cab, step side. Powertrain is original, 221K miles. I pulled the shift lever down into 1st gear, but when it hit 4K rpm it shifted on its own. This surprised me...

    Heat riser - necessary? 1994 TBI 350

    That's interesting! Do you still have that letter? I'm sure we'd love to see a copy of it.

    88-91 vs 92-94 DASH DIFFERENCES - do they matter?

    To be completely transparent, if I'm going to all of the effort to rebuild the dash, $399 seems pretty dang fair and only logical for a brand new dash core. I'm not going to all that work for a used one that has already aged itself.

    Heat riser - necessary? 1994 TBI 350

    Yes, but our humidity is next to nothing. I've never in my life heard of a throttle body icing, and I think that's indicative that it's not a common issue in the southwest.

    To answer your question, I live in the White Mountains at 5600 ft. Our winter nights can get down to 0. Commonly between 10 F and 20 F during January.
