Stock and Super Street....

[Tom Goldman]

Marty Ganjoin runs a 69 camaro in D1 that is a "stocker " more than many legit Stockers. Calvert rear suspension on 9" tires and his car hits the tree with fairly large front tires, and hundreds of pounds over the 2800 minimum . I'd say around 26"inchers. Uses a small , 427 based big block. [ not Keiths version of a 427 !!]
Marty;s been A Division champion ,Jegs Allstar ,MASSA Super Street champion with it ,so I'd say yes , you can easily do it.
Might take a little work to hit the tree to .00's ,but very doable .
The wheelstand is not a big issue and might just help with the reaction time on the Pro tree.
The biggest issue you might have is your competitors rushing to stage first against you since they know you''re footbraking .

The staging lane directors point me to the Stock lanes all the time. 9" radials, CalTracs, 3600 lbs, 28" frontrunners. I carry .050-.060 in the delay box but that is with a Pro tree transbrake and I won the division title in it in 2015.

I can't speak to all of the particulars of the car, but the #2 finisher in D5 this past season has small tires, is heavy, and uses weight and shift point to hit the number.

I'm not sure what it would be like to hit the tree off the foot, but I agree that there isn't anything else that sounds like a concern.

My brother Vince won Div. 5 Open @ KCIR some years ago w/ 1967 Camaro, 355", Jerico, 9" tires. No electronics, just adj. weight, ran 10.90@125. Eventually ran same car in A/S W/396/375, car weight 3400#. We had a blast.

Years ago I used weights to hit the number...four straight dead-ons, that was a very good day but there was no wind to deal with. When conditions were trickier I’d have to hold a bunch, changing timers is a whole lot easier.

Should be no problem with the.470 pro tree.

What are some ways to reduce reaction times with a "Stock" style suspension set up to hit a pro tree (.470) in Super Street. My set up is a lot like Marty's Camaro. 67 Camaro big block, 3600 lbs, 30x10.5 Pro Bracket Radials, caltracs bars and leaf springs, moroso trick springs up front, afco double adjustable shocks all around. I've set the front shocks to stiffest rebound setting, and installed travel limiters on the upper control arms, 26" tall front runners. Even when rolling WAY into the bottom stage bulb, I can only be .030-.050 on the .470 tree. Obviously, there is no consistency when staging like this. I do not use a delay box for obvious reasons, can't hit the tree without one, so why have it. It even has a 2.75 low gear set in the tranny, 4.30 gears and two step is set at 3,000 rpm. I've tried a higher rpm launch, but it spins the tires more often with higher rpm launch. Any ideas would be appreciated.

In theory your car should be able to react much quicker than mine, but you're nearly .100 behind what I'm getting staged dead shallow.

I wonder if it would be quicker if you reset the front shocks and travel to allow the car to work at a higher RPM.

A pro-tree transbrake? A quicker button?

Converter change.

Put a pro brake in it, cal tracs, 9" tire, 2.75 1st gear.....QA1 Rears, Tinnen Fronts, 26" front tire.....Rear Gear is a 5.13. Will be wincing a bit at the stripe. Some of those sst's are 160-170 mph these days.
