I'm curious to know if you think that I just have a bunch of parts thrown together or if I could make small modification to improve my performance.I drive it on the street often and do a little drag racing on 1/16 mile track friday nights. Could I have my cake and eat it to.
I originally had a smaller cam. ,stock converter, no shift kit, 273 posi. gears,
and smaller rear tires. All these modifications seem to help; but just wasn't enough. I NEED HELP TO SEE WHAT I'M DOING WRONG!!!

I like the Ideas generly, would suggest different headsstandard 390" C8EA-H not the best, need some flowbench/porting by somebody who knows 390-428" fords / or probuly cheaper the new e-bocks.Stocks springs are nor going to cut it too.
As much as I like the looks of the tri-power the manafold will not flow enough to make horsepower, again a e-bock performer RPM unless you can weight for new Victor
You did not say anything about exhaust system ,a set of super comp headers ,abitch to install but will make the thing wake up
Just my $0.02

1/16 th mile track?????  That's what I'd like to know? Anyway Chas, welcome to M&M  ! How quick was it and how quick is it now? You probaly need some fine tuning. Do you have an upgraded exhaust? I made many a FoMoCo Tri-Power set up fly and I still do.  1/16 th mile track huh? Hmmm?------------------

there IS a 1/16th mile (330ft) dragstrip on Vancouver Island (Saratoga Speedway), AND a 500ft one too (Western Speedway) Anyways... the combo sounds OK, the valvesprings are a weak point for sure, and headers will make gobs more power than the exhaust manifolds. Those heads aren't the best but will work, same deal on the Tri-Power , neat looking setup but not the fastest. Then again, if the car is to have fun with rather than trying to run as close to "zero" as possible  it should do the job... just make sure the valvesprings don't coilbind and be aware they'll float the valves much earlier than stronger springs.

Yes, 1/16 mile track,just a fun track not pro
it is the front stretch of a circle track.
Nothing serious just for fun.As far times I'm not sure; but after modifacation it became quicker. I have stock exhaust manifolds and H-pipe w/ 2 chambers flowmaster mufflers. I will try changing my vavle springs and I also am going to switch from the H-pipe to an X-pipe I,m told they floww better exhaust. But I can't change to many exterior parts; because the class I run in is supposed to stock class;Moneymaker could you reply on how to tune a tri-power correctly.

Hey Chas. Forget about the "X" pipe and concentrate on a set of headers. The stock 390 exhaust manifods are killing you. You don't even have to buy Hooker Super Comps. Get some Headmans or regular Hookers. That will help you tremendously. Then I can help you out with your carb set up and you can realize all of the improvments. ------------------

1/16 mile on an oval... hope its paved! And not banked too steeply  That track in Binghampton? If its a stock class the tri-power isn't stock... and like Alex says definately lose the manifolds ,GT exhausts are as bad as they get. Headers will wake it right up. Even an old dented set of Cyclones or Caslers are a huge improvement.

by the way those two tracks i mentioned are both using ovals, one has the strip built across the infield running over the middle of the curve, the other starts in turn one and races off past turn 4, the shutdown area on both are outside the ovals.

Not trying to piss off your neighbors in Binghamton too much... but you have a ready-built drag strip in town... heres a shot of the old Chenango Landing Field just north of town... looks like a good 1/4 mile if the residents dont mind a wee bit of noise http://terraserver.homeadvisor.msn.com/image.asp?S=11&T=1&X=1077&Y=11678&Z=18&W=2 [This message has been edited by TomP (edited 03-05-2001).]

TomP The track is black top and we run on the front stretch between turn 4 and turn 1.
The reason I can run stock with a tri-power is because it is an original fomoco intake and original carbs. Probably some that could have been a factory install option or a dealer install option. And that landing feild is dirt runway. I've been their for an air show recently; but thanks for looking.
