One of the main things I got from it that might pertain to a heavy coil spring Stocker is that if you are getting 100% traction without a lot of front end rise, then don't loosen up the front or use 90/10 shocks. What you want is to use all your power for propelling the car forward. If front end rise is not needed for traction, then your ET will be better if all your power is moving the car forward. Also, I read that you want soft springs to help traction. But, this guy says that for a stock suspension coil spring car, you want stiff springs, so that all the weight is used to push the tires into the track. If the springs are soft, then on the initial hit, the body will squat, instead of pushing down on the tires. Makes sense to me. And the part about the '71 Monte with nothing but air shocks: if I remember correctly, that was a heavy body style, very similar to the '69-'77 Pontiac GP. So, that may be a further indication that all these fancy suspension pieces are not needed for a HEAVY, low buck Stocker. Would probably be a good idea to start with stiffer bushings, stronger springs, air bags and stiff shocks--try that and see how it works, before spending a bunch on parts that may not be needed at all. |

[QUOTE=oldskool;458884]Wow ! This blows my preconceived ideas out of the water. That site has some great info.

With the small cubes I don't think the small intake valves will hurt a thing. Hey, them screamin sbc motors only have 2.02 valves. And with the almost unlimited duration available from a Bullet Stocker cam, you'll have all the flow you need. I'm thinkin you'll need to turn it at least 7000rpm +. So I reckin you'll need some heavy springs and some of those Sherman tool steel lifters like Brent is gonna get. What do you think ? At least 4500 stall ? I bought a '69 Tempest 350HO ex-Stocker to run bracket with. The dyno sheet said it made 434hp. But it was not tricked out. Just a stock rod, TRW engine. Ran mid 12's. I had a diesel crew cab, a two car gooseneck, and 2 Pontiac powered bracket cars, for the 2010 season. But our local track did not open the entire year. Sold the truck, trailer, T-body and the #48 heads. Hey, don't forget. Start that build thread ! |

It worked, but think of how much quicker it might have been using todays suspension technology!![/QUOTE] What I got out of what the guy said, that I think might apply to a HEAVY (over 4000lbs) Stocker is that IF you are getting 100% traction without a super loose front suspension and fancy rear suspension pieces, then you will not go any quicker by using these other parts and methods. I am thinking that one of these HEAVY cars, especially a wagon, will have enuff weight on the rear tires to get max traction with only stiff bushings, springs, shocks and air bags. But hey, I could be wrong. If so, it won't be the 1st time. The only reason NOT to go with the latest and greatest is $$. If you have the coins to spend, by all means, by the best of everything. But I'm talking about what you can get by with for a very low budget build. |

Re: Ol' Fart's Firebird Fantasy
No, actually, I don't know anybody on here at all. So by what you said, I assume that you are a die hard stick guy ? Do you (or any of the stick guys) still win a lot of rounds, even with the bracket racing nature of today's Stocker racing ? You said you got a CP piston approved for the 350HO. How long ago was that ? What is the CP part number ? It's not listed on this site yet. They still have only the TRW. Would you please post some pics of these CP pistons ? Do they have floating pins with spiral locks or ? http://www.classracerinfo.com/Engine...px?ENGINE=2008 Last edited by oldskool; 01-18-2015 at 09:55 PM. |
