Re: Ol' Fart's Firebird Fantasy
Now, I think all these '76 Pontiacs except for the Birds had coil spring suspension. The Cal-Trac type set-up seems to be pretty much std equip for today's leaf spring Stocker.
But how about the coil spring cars ? On my '69 GTO, all I did was stiffen the rubber bushings with finishing nails, and run air bags, with more air in the passenger side bag. It worked OK on a mid 12 sec car. http://www.jegs.com/p/Air-Lift/Air-L...43887/10002/-1 So what is the best legal set up for the coil spring suspension on one of these heavy cars ? If there are any aftermarket parts involved, please list brands and part numbers if you have them. Links to them would be great. Whether I use a coil spring car or not, there is probably somebody who will read this who can benefit from a detailed description of a good coil spring set-up for a Stocker. Thanks in advance for sharing this info with us. |

OK, that's one vote for no hop bars. Is that what most of you coil spring guys are using ? |

Re: Ol' Fart's Firebird Fantasy
Lots of companies that make great suspension components out there for A Bodies. Even though lowers can't be adjustable per the rulebook, adjustable uppers, a good anti roll bar and shock package will allow you to make changes on the car as needed. This is just a couple of examples of companies that make great products.

Re: Ol' Fart's Firebird Fantasy
I`m working on the `68 350 HO right now.I got a CP piston approved by NHRA .I think the only thing hurting the motor will be the small intake valve it does have the same cam,carb and intake as the 400 so it can`t be that bad.That being said I still think it needs another 5 or 10 hp off.

(1) Does anybody have a link to a site or sites with pics and explanations and/or installation instructions for these devices ? (2) Is this what most of the quicker Stockers are running ? (3) Would these be required on a 4000 lb + car, such as a wagon ? Or will the large amount of weight make these extreme components unnecessary ? (4) The adjustable uppers that were mentioned. Does that mean that most cars need shorter arms ? or longer ? (5) Are the different length arms to change pinion angle, or suspension geometry ? (6) What about the coil spring "slapper' bars ? Are they totally useless for Stockers ? Sorry about my ignorance on this subject. I've just never used any of the above products. http://www.jegs.com/p/Competition-En...37234/10002/-1 Last edited by oldskool; 01-18-2015 at 06:09 PM. |

Re: Ol' Fart's Firebird Fantasy
This site is a good source for answering a lot of your questions.
http://www.baselinesuspensions.com/ Necessary to me would be anything that gives an advantage, but at the same time, I had a 71 Monte Carlo SS 454 back in the early 80's that would run 11.50's with 1.50 sixty foot times with nothing but air shocks on the rear, lol.

Re: Ol' Fart's Firebird Fantasy
Aftermarket adjustable upper arms are legal, but you must use the factory front attachment point (no extra holes). The rear attachment point can be relocated.
