Baffled engineering strikes again!

[Goat Hearder]

Hi! Been awhile, Have a new 8" converter in the '64 GTO Leaves much better! Blows the 9" off Lowered pressure and hooks better Down track gets a bit loose! Car usually goes straight as an arrow Shocks are QA1 coil overs single adjustables. Think maybe set to soft for the low tire pressure and it was "strange" going down track. Is it a wise idea to ditch the stock sway bar in favor of something hd race car style Thanks The car has been running 10.90 - 11.00's. Picked up a couple bucks @ Pontiacs in the Park Dinwiddie Va. for the fastest Tri-Power in attendance. (Glutton for Punishment). Thanks Hope to be able to spend a bit more time on the forum. Dumb Question all have a decent year?

How heavy is the car and what springs do you have in the rear???

Car is about 3000 lbs' with me when my buddy drives ( We share the fun) about 35lbs' lighter (skinny old guy) the springs are 95lbs and scaled about 56% front 44%rear (if memory is correct). Moroso trick fronts and 90/10 shocks. The springs are in the range of the front end weight. Used to have a 10" street/strip converter which when foot braking to get the RPM ( she had a slight stumble, those fine ole 2G Rochesters Tri-Power) up really tweeked the hell out of the car. Now she is not as loaded. First couple of passes blew the 9" x 28 " slicks off. Less on the second. Got better with more air out of slicks, but screwed up and softened the shocks to which I think made it twitchy going down track, (1/8th mile down here). The car has usually gone straight as an arrow, and I had an old post with a photo(hammern' the slicks) at Dinwiddie Va. Thanks for any thoughts. You run at Island, E-Town, or Atco. I spent my upcoming years in your neck of the woods! Garlits and Ivo at Island first Drag Race! Any way thanks!
