^ Agreed. Everyone had there own way of adjusting the tranny cable off the TB. Raptor Transmissions actually made a little fix for that. It's a tiny little spring between two little plastic washers, kinda. Worked Great!

It's actually not hard to figure out if you know anything about the cars......especially the autos of that era. Typically they woukd shift way to soon and the cable style adjustment never seemed very consistent. Shift points would even change with engine/trans temperature. The fix for that would be to shift the auto trans yourself.......although that was usually not implemented in standard testing procedure. We would shift dads auto tpi car ourself. I had a 305 monza back then. It ran a 15.1 @91 mph.....his iroc would wax that thing.

Lol.....troof
Maybe your l98 is not running right. It shoukd easily run 14s in good running order. Mm l98 vette has been low 13s with very few mods.
Lol.....that will work to

The only 15 second Mark VIII's were the 97-98 cars. The one I have is a 96 LSC. Better exhaust and a 3.27 posi rear end. Easily a mid 14 second car. The LSC cars trap 95-97MPH stock. The IROC runs fine, it's just a slug. 2.77 gears don't help it any.

Little more to the story than that. You wouldn't correct times because you needed the da advantage. His car had a 350 but on the 305 tune because someone changed it. It woulda likely ran better with the 305 in it vs the 350 with a 305 tune. And you needed a weight advantage.

Do you comprehend how ******* ignorant you look? 
My car was BONE stock. All smog, all everything, zero weight taken out. I even wrote a note on the weight slip for you, if you remember. Yeah I've heard your "the 350 was at a disadvantage compared to a 305" story before, and I laugh a little more every time I hear it.
