Re: Track results....
 

Hey Super 73,

Nice Truck! Man, that thing launches great and sounds just plain evil! I was wondering, are you going to be at Sac on the 26th of this month, some friends and I are going to be bringing our junk to the track for a day of racing. Here's the the info:

Sat...26 Test and Tune

Drag Racing All vehicles must pass a regular tech inspection. Vehicles quicker than 10 seconds will run single passes.

Times: Pit Gates Open: 10:00am. Testing 12:00pm-4:00pm

Admission: General Admission: $10

Racers: $50 (car and driver)

One friend will be trailering his 1954 GMC 3/4 ton (formerly a long bed), Hillborn injected Caddy 500 powered backed by a tremec 5 speed drag truck, I'll be bringing my 1966 C10 panel to race ( It's nowhere as fast as yours! ) and have some fun, as well as a few other trucks/cars.

We will probably be there all day from noon to ten, if you can make it I'd love to see your truck in person/make a pass or two.

Motor has forged rods/pistons, stock crank, ported stock heads 243/250 @ .050 .610/.612 108/110 cam, underdrive crank pulley, stock LS6 intake with ported filled throttle body and F-body long tubes.

I'm not sure when I'll get to Sacto again.. I promised my wife I would put the truck away for a little while and get some crap done around the house since it is staying lighter longer now.

Re: Track results....
 

Thanks for the info. I always liked the LS1 power. Where are you located? Never heard of your town.

Re: Track results....
 

It's near Montery...

Re: Track results....
 

Nice runs!! Love the video of launches!

Re: Track results....
 

Best pass http://73-ls1.com/63truck/track4-4/100shot.wmv

I lost a fuse on the second stage so that pass was only the 100 shot at the 60' mark. The second stage is a 200. I was going to use them both same time. I think it would have gone at least 10.999999.

Re: Track results....
 

link won`t work for me.

Re: Track results....
 

Here are all the passes we got on video..

Best pass on motor was 11.9x @ 113
Best (only decent N20 pass, lots of issues) was 11.28 @ 115mph spraying a 100 shot from the 60' mark. Tried grabing all 300 after the 1-2 shift but the fused poped in the direct port.

Re: Track results....
 

This one didn`t work for me either. Says page not found.

Re: Track results....
 

Re: Track results....
 

Very nice. Are you using the injection or did you switch to a carb? What tranny and rearend gears are you running? Awsome truck man. i would love to have my 62 run low 12`s-high 11`s someday.

Re: Track results....
 

Super...are you running a front sway bar on yours?

Truck is looking good!

Re: Track results....
 

No sway bar.. Why you ask?

Re: Track results....
 

It's still injected using a F-body PCM and harness. I'm runiing a 4L80E trans (Heavy beast). Stock 12bolt rear with 3.73's. 4,400 converter with 30" tire.

Re: Track results....
 

Because mine is still on and I was thinking of taking it off....just to see how much it helps to transfer some of the weight...

Re: Track results....
 

Mine never had on and there are no holes for the mounts either. I'm wondering if this is a later addition. I do have a front sway bar at the shop though off a 8luch dually that I was thinking about putting on. Just to see if it did any good/bad.

Re: Track results....
 

Thanks. your getting awsome power from that motor. Really doesn`t matter but i`m curious, whats your fuel mileage like?

Re: Track results....
 

Here is a detailed spread sheet showing all the times from this weekend. N20 passes are in Blue, only one was at full pressure. Red backrounded items are things that I feel were out of the norm and could be improved. IE the 11.2x N20 pass, I shortshifted 2-3 and only gained 19.x mph where even on the motor I'm gaining an average of 21.x on the back half.

Fuel Milage?? Now that's funny.. When this heads cam package was in my buddy's 2000 Camaro, he would knock down 20-22mpg on the way to the track. I get 10mpg.. I think I have some more tuning to do at cruise and can get more out of it, but I am going through wideband very quickly. It's rather sad.

Re: Track results....
 

I`ll bet the camaros aerodynamics is quite a bit better than the truck so that will play a part too. On something like you have mileage doesn`t really matter, at least to me, I was just curious what you got.
