suspension and ignition setup need help
 

I run my 66 chevelle in a club racing event called supercar shootout. Stock tires, stock intake, stock exhaust manifolds. I'm running an msd digital 7 box with a stock eliminator style big block. Best run 11.22 @ 122mph. I know there's more in it and I'm looking for someone with the knowledge and talent to help me. I'm willing to meet at etown atco or cecil county and compensate anyone willing to help me pick the car up.

Any suspension modifications allowed? I'm sure your 60' times could be improved upon. What type of rear tire are you calling "stock"?

http://www.supercarraces.com/SC2014-13.jpg G70-14 redline. Best 60 ft 1.74. I'm pulling out 15 degrees of timing for 1.5 seconds leaving off the foot brake. I know the digital 7 is capable of much more than I'm using it for now. I have santhuff springs up front with del alum bushings and single adj. QA1s. In the rear UMI adj. uppers, boxed lowers stock springs and sway bar and double adj QA1s. I'm losing ground to some of the other racers who have figured out how to get high 1.5 to 1.6 60 fts.

There are a lot of folks on here that could help you, but I think they would all need quite a bit of info about your combo. 11.22 is pretty stout on redlines, and is at or below the index for your 66 with any engine except the aluminum head 396/375hp at 11.20.

The class is run heads up with a sportsman ladder. .400 pro tree. My combo is a "stock appearing" 360hp automatic with a turbo 400 and 4.56s. The motor made 660 on the engine dyno running through the stock exhaust manifolds, correct oval port heads, and cast iron intake which uses a holley. The car weighs 3845 with me in it. The dominant cars are hemi mopars and L89 69 camaros and novas. I feel the front of the car works well but the rear is where I could use the expertise of someone else. As well as getting full use of the MSD.

What do they allow on the rear suspension?

Re: suspension and ignition setup need help
 

your performance is commendable giving the information posted.

If you can get to the point where it will leave without retarding time, that will be a big part of reaching your goal.

Have you tested with fixed timing? If not, try and see what happens.

Agreed - Without a tire swap the only other thing I can think of as far as suspension are no-hop brackets...https://www.summitracing.com/parts/qa1-5213/overview/

These were used on my partner's '66 with success for a 1.51 60'...he had less hp and was closer to 4000 pounds, but did use slicks for those runs. Unsure with those tires what the outcome of a higher stall converter would net.

No hop bars are allowed. not much else. Trying to leave with full bore timing blows to tire away.Adding weight ballast in the trunk has been suggested but putting an extra 200 lbs in the trunk and dragging it down the track is a tough pill to swallow.I know the digital msd is capable of ramping in timing in different ways I'm just not sure of all the things its capable of. Rear shock settings are another area where I know someone with more knowledge could be helpful.
