Alright, went to the Lebanon Valley Dragway for their Musclepalooza yesterday. Took our 3 "race cars" out there to have a little fun. My car was spinning bad. Ran 13.8 on the limiter in 2nd gear, then switched to a slower class and went too fast at 13.32 slamming the brakes hard on the top end. Dialed a 13.50 and decided to just baby the car. Realized I could spin, and miss gears and run 13.5s all day
For the fun part
Dads 393 stroker car. Simple combination, 351 truck block, non forged crank (393 inches all together), truck rods, SRP pistons set up for the bottle, Untouched AFR 185s (the upgraded version), 690 lift solid roller (slightly choppy 900 RPM idle, pretty tame for the numbers on it), Vic Jr style Ford Racing intake, and a custom carb from a local guy. All in all a very budget build on the motor.
The chassis is a simple 8 point caged 91 LX. Rear seams welded, sub frames, 8.8 with a spool, axles, c-clip elims, and 4.30 gears. Adjustable Uppers and Lowers, shocks and struts, tubular K and A-arms, manual brakes and steering.
The best part about it, it's a stick shift car. Jericho 4 speed with a Mcloud soft lock and vertigate shifter.
First time out with it yesterday, having only run it once before and never able to floor it, it went like this (my dads words from another forum).
Pass 1 off the trailer. I decided to make a easy run just to see if the car would go straight.
3000 rpm launch.
Granny shift all gears at 5200 rpm
If the car is going straight stay with full throttle. It did stay straight.
And the results are.........
10.67 @ 123.99
1.62 60'
6.89 @ 104.44 at the 1/8
The car nosed over about 100' before the finish line. I thought it was running out of fuel because it shut off before making the turn off. Started it back up and drove to the pit where I added 1 lb of fuel pressure. As per my engine builder suggestion.
All felt good and I was happy with the results.
Pass 2 feeling good and decided to up things a bit.
5000 rpm launch
Shift harder, but still not power shifts. Shift point upped to 5600 rpm.
Run it out the back half.
10.45 @ 131.02
1.54 60'
6.77 @ 105.47 in the 1/8
Car still nosed over at the finish, but seemed to be a little close to the stripe. Added another lb of FP.
Pass 3 not caring whether I win the round because this was just a shakedown for the car. Actually I had decided this was my final pass regardless and decided to lean on it a little harder. I put a 10.30 dial in on the window figuring if I break out I will be happy with the results.
5400 rpm launch
6200 shifts, still not power shifting.
Run it hard the whole track.
10.13 @ 130.92
1.39 60'
6.49 @ 106.89 in the 1/8
and the car still nosed over right before the stripe. This time I noticed it acted like it was flooded when I tried to restart it. My diagnosis that it was running out of fuel was wrong. After some quick calculations by Jay it seems that I'm hitting the rev limiter. I had to use Randy's 27" M&H tires because it was the biggest tire that I could get that would fit under the car and this proved to be my undoing. Mathematically speaking 27" tire and 7000 rpm = 131 mph.
All this and the track alttitude was about 1850' according to the temps.
"Cliff Notes" Dads 393 stroker race car went 10.13 @ 131 with a 1.39 60' on it's 3rd pass since the suspension was finished. Granny Shifting it, short shifting it, low RPM launch, running out of fuel on the wrong tire.
I know it hasen't run it yet, but I would with confidence say 9 second all motor stick shift car. We should know a week from Thursday though
