From what I have read on moparts is the cal tracs didnt seem to make much diffence for alot of people on here with mid to high ten secound cars.




I'd disagree with this from my experiences with them. A well sorted out SS spring is more difficult to improve upon. JMO, An 11.00- 123+mph car running 1.6x's in 60' is not a well sorted out car.




I agree, my 60ft's didn't change going from Dvorak SS springs to Caltrac's. But what I did gain was some adjustablity for bad track prep. I 60ft in the mid 1.40's and run 10.40-10.50's

Randy, what kind of shocks do you have on it, both front and rear? Are your springs clamped real tight on the front segment and unclamped on the rear? Also, what converter are you running? Just thinking out loud. As for making more power with the new mods, I'm sure you will be pleased!

The X' is slightly heavier than a no frills RR. So, front end rise IS important. The better the weight transfer is, the BETTER the "hook" off-the-line. I'm assuming you have the subframes connected, so the wisest things to do is make sure your SS or Caltrac springs are set with the rearend correctly shimmed for the proper pinion down angle. Front end also has to be set for maximum rise under acceleration, but not uncontrollable. The trick is to shift weight to where it's needed - over the rear wheels, under acceleration. And a pinion snubber can't hurt either, just makes traction even better.

Thanks guys! I know the suspension isn't optimal by any stretch...but MUCH BETTER than it use to be! For a 3,500 lb. street car,I think 1.52-1.56 short times are decent. Can they be better?..I'm sure they can! I'm currently running Calvert 90/10's in the front..with NO sway bar. Out back are Rancho RS9000's and 002/003 SS springs..with NO additional clamping. The frame rails are tied,and I run a 4:56 gear...and Dynamic 9.5" converter,that flashes to 45-4600rpm. As far as chassis improvements..I'm open to ALL your ideas,and opinions! I have thought about having one of my friends set up a ladder bar system..in the near future! As far as the pinion angle is concerned,what would be OPTIMAL for a street driven..occasionally raced car like mine?...I believe Gary Jacob checked it,and it was 5* down. Thanks!

Wow Randy your car is set up pretty close to the way mine is.except i have the cheep summit 90/10 shocks on the front and some after market rear shocks for a dodge ramcharger.I am using 4.30 gears and some M/T 275/60/15 et drag radials. My best 60 FT has only been a 1.54 but most of the time i am in the upper 1.5 second range.I am guessing my 73 dart weighs around 3500 with me in it.I just put two Holley 750Dp on my car so i hope it runs faster next time out.But with the new engine mods and some tuning i think you can hit your goals and maybe more.

Bobby..I LOVE the Calvert front shocks! HUGE improvement over the CE and Lakewood 90/10's that were on previously! I'm thinking the pinion angle could be improved,if increased to 7* down...from 5* down. But,I could be wrong! Need to find that out! Take care,Brother! Thanks for your input!

Randy I run just SS springs with long C-body shocks in the rear and 90/10 shocks up front. Everything else is dead stock. My best 60 on the 30 x 9 Hoosiers is a 1.50 running 10.70's. If you get in the low 1.50's that not to bad. Good luck with it , Ron

I had the same setup as you and went 1.43 but in a lighter car. Your 60ft times look ok for a low 11 sec car, i would just put the motor in and tune from there.

The first time I brought my car to the track it would top the front shocks out then spin the tires. I put a set of longer shocks it and completely fixed my spin problem.

Randy - be serious... your car needs basic chassis tuning, not a friggin' ladder bar setup.

My Challenger runs 10.5s @ 3755#s w/ 1.45 60-fts on 275/60R15 ET Street Radials using CalTracs. They were worth .04 over a sorted out SS combination, plus added tuneability and consistency.

Like they said above you dont need ladder bars to make it hook up. My car is basically stock suspension and springs and it hooks up and runs 1.49 to 1.52 60'. I would make sure you have alot of up travel in your front shocks.

I'm sure it will dip into the 10's with the increased power. I bet the 60 ft times improve as well with the added compression and head flow.

According to the wallace calc, a 1.52 60ft is a 10.94, that says your car is where it should be.
As said by the previous poster, when your power increases your 60ft will drop at the same time.

Randy to help with your chassis works I have question when you painted your car did you fix your frame rails????

Hi,Gary! Yes!..Steff replaced the section under the steering box...and reinforced it. Gary..would dropping the pinion angle from 5* to 7* help anything? Thanks! I think down the road,I'm going to have you check EVERYTHING out and advise me on what can be done to optomize my set-up!

Just last night I turned my pinion angle from 2 degrees up to 4 degrees down. We will see labor day weekend if it helps my 60' at all. So I have a hard time thinking yours isnt hooking up good because of the pinion angle. Im suprised mine hooked up with the nose pointing up like that. Like I say my chassis was basically set up very poorly and it still hooked up and ran a 1.49 60' so I would guess that you have another problem somewhere esle.

Randy pinion angle is a requirement to avoid u joint bind if a car picks up when the pinion angle was changed then it had bind. I dought if your car has bind with 7. We played with lens car for three years and only played with shock and front travel and picked up 4ten. to were we had an issue with to much wheel stand so there is alot to do with your stuff. what do you have for shocks? OOPS I GUESS I SHOULD HAVE READ AL THE REPLIES AND GET CAUGHT UP FIRST BEFORE I POSTED.HMMM CALL ME.

Randy I think ladder bars would be a bad move from the stand point of the purpose of your car. It is not a all out drag car. Would it pick up maybe alittle will caltarcs work, yes a little but for as often as you go to the track I dont think that would be in your best interst. I would be proud to own a pump gas motor that I drive to the ice cream store or berger joint that went into the tens and sixted into the 1.40's Your get what its got. Just tune it to its potentual and be happy. You will be just fine. You have nothing to be ashamed of. I built a car for my brother that he just wanted to go mid elevens with it so I put in a small Scoty Brown cam with ez heads on a 440 with one of those indy crossrams and 2 750 edelbrocks and put in way wrong converter for combo and the car on a good day will sixty 1.49 and go 10.30's at 131 mph. Talk about a turd out of the hole!!! Im imbarresed but he is happy he is going way faster than what he wanted. Maybe down the road we will change converters. Enough of me reambling but what I was trying to get to is when do we say enough is enough and live with or decisions and have fun. Your going to have a car that is going to give you allot of grins have fun just playing with its tune and see what gives a pay increase or decrease!!!
