Made my first pass down the strip.
 
And a second and a third. Best was 13.484 at 104 mph. It was just a test and tune night. Time to start making changes to try and lower the 60ft time. Best was 2.178. I have a supercharger to go on it, but that will be further down the road.

I'll post a picture of it tomorrow.

moving out! Anything done to the ole girl?

Re: Made my first pass down the strip.
 
It has a 428 cu. in. Dart blocked, "LS" motor in it. 4l80e trans and a 14 bolt semi-float axle.

Motor was built to run a Whipple 2.9 Supercharger, which has been been rebuilt and will probably go on sometime this Summer.

Nice! I am putting one of those 14 bolt's in my '65 for fear that the 12 bolt wont hold up to the 550 hp my measly 383 puts out!

A truck 12bolt will hold 550 no problem. If anything at all I'd just do c clip eliminators and good axles.

OP, is your truck 4wd? You have a brace kit for the idler and pitman arm and set of sleeves or rare parts or similar tie rods? Launch that thing in 4hi and see if it brings down that 60'. If you don't have those items, deffinitly don't do that though haha.

litebulblsc 06-01-2023 09:35 PM

Re: Made my first pass down the strip.
 
I have the thick tie rods. But 4wd launch would slow me down. I was not spinning at all. My brakes would not hold to let me come up on the convertor. And it was dead hooking and "bogging" from the hit. I am looking into different tires (shorter and lighter then the 33"s on it) to help next.

Re: Made my first pass down the strip.
 
I got my "race wheel and tires" set up and tried to make it out to the teack today. But the truck is acting up and stalling, so I turned around and headed back home. I was within a mile of the track.

Got the running issue resolved and got a rain free Wednesday.

Made it up to Milan and made a few runs with the new tires. Ran a new best of 13.298 at 106 mph. The DA looked to be about 1200 higher this time compared to last time.

New wheels and tires are 3" shorter. And all 4 equal out to 100 lbs lighter then the all terrains.

I think it is getting to be time to add the supercharger.

Yes, speed is addicting.

Had a cool Wendesday, so decided to go back to the track. Got a new pb. Now I can call it a 12 second truck. :sexy: :burnout:

Re: Made my first pass down the strip.
 
I got new o-rings and gaskets coming for the supercharger, should be here early this week. I need to go through all of it and see if I am missing anything. I know I need to find a 10 rib idler pulley. Then once it is installed, I will have to measure and find a 10 rib belt.

Re: Made my first pass down the strip.
 
Well, I thought I was going to be good to make it to the strip this week, but ultimatley I only made a belt shredder. I have an aftermarket 10 rib idler pulley that cocks sideways under belt tension and causes the belt to run off center on the crank.

The worst part is that I cannot find another belt in stock anywhere I have looked.

biketopia 10-04-2023 09:19 AM

Re: Made my first pass down the strip.
 
That stinks, what belt # you looking for?

litebulblsc 10-04-2023 03:18 PM

Re: Made my first pass down the strip.
 
That belt was a K100955HD. I am changing things up and will be using a shorter 10 rib belt for the supercharger and waterpump. Then a really short 4 rib just for the alternator. The only down side is I could not come up with a good way to drive the powersteering pump, so I bought an electric power steering pump.

Weird you couldn't find a belt. NAPA shows 13 in their distribution network, 3 at my local distribution center, one in phoenix, and 9 through gates.

litebulblsc 10-05-2023 08:20 PM

Re: Made my first pass down the strip.
 
I did not check with Napa. I am not a fan of their local store and I do not order online from them. But I did just check and they list it at $160.

I paid $90 at Summit and $75 at Rockauto for the 2 I destroyed.

biketopia 10-06-2023 06:19 AM

Re: Made my first pass down the strip.
 
Ahh, we don't use the local NAPA much anymore at work ever since they went fully corporate. They were the best little community parts store but now....Either way sounds like you're on a better track by changing up things, shredding almost $200 in belts is no good.

Re: Made my first pass down the strip.
 
Made it to the track today.

I knew I was going to run into traction issues now that I am making a little power.

First pass I blew the tires off. Nothing there. I did not bring a pressure guage and I had no idea where they were at. Borrowed a guage from a fellow tester and holey moley, they were at 37 psi. I dropped them down to 20 psi and got back in the lanes.

Second pass, I noticed in the burnout box the pressure drop was going to help. Leaves good, throw the shifter into second but it does not shift. I bump the shifter again just as it shifts into second and it goes into 3rd. I messed with the settings a bit in the Holley, but I am going to have to learn how to tune the transmission control. Got back in the lanes.

3rd pass. It left alright, shifted 2nd still a little late but not horrible. This time it did not want to shift 3rd and I ended up in 4th so I lifted and rolled to a 11.501 at 101 mph. This is now my pb. Messed with the setting in the Holley again to try and get the shifts doing better. Got back in the lanes.


4th pass, I can't even fully remember what happened. I think it spun a few feet out, so I short shifted to second and then loss power. I thought the engine died, but it was still running. I get to the side still rolling- don't see anthing leaking on the track so through it back in first. It would only go 12 mph. Make it to the end of the track and stop in the return lane. I saw my alternator was not charging and thought maybe I lost both belts and that was all the air the engine could pull through the supercharger.

Popped the hood and only the alternator belt was missing. Did not see any other issues. Fire it up and it seems normal again. Decided to drive it home without the alternator. This is where I screwed up. Made it out of the track and started down the road. And bam. My new hood was inside the truck with me. In the fluster of deciding to drive it home as is, I did not check that my hood latched. So I ended up driving it home with a super busted windsheild and no alternator belt. Made it home, about a 1/2 hour away, at 11.6 volts.

Now that sucks. Not only are you having to fix the alternator, but you have to fix the windshield. Sorry to hear this after getting to make a few passes down the track.

Cracked my new plastic hood and bent the hood hinges. I am in Michigan, and drag racing season is about over for us

Made it to the track yesterday. I'm not sure if it was just the weather, but the traction was not there. After pulling some pressure out of the tires, and some timing out of the motor, I was able to leave softly and run an 11.63 at 117. The online schedule shows that was the last Wendesday test and tune of the year, and the guy at tech was unsure if it is or not.

I am thinking a good upgrade for next year is some Caltracs. I am just not sure if they will help enough or if I should ladder bar it or 4 link it?

Here is the best time slip from last week and this week. I know the reaction times are embarrassing. I waste the good reactions on crappy passes

biketopia 10-20-2023 06:31 AM

Re: Made my first pass down the strip.
 
Cal tracks would be a good upgrade. Ladder bars would not be hard at all to build your own set if you have the ability. Helped a buddy put a set on his truck, pretty simple design and they worked wonders on axle wrap and wheel hop. If you can tame your rear end and get your 60ft time down you'll have something.

My best 60ft was 1.62, which I feel is good. I just want to get to were it can do that more consistently.

I have some work to do before the season opens up next year( and about 6 months to do it).

Still looking for a 2wd short bed standard cab of this generation to build a real drag truck out of.

Well that's some bad luck. I forget that there is a racing section here. I like drag race threads. I don't understand your numbers though. I have never seen a time slip/drag strip set up like that. I'm sure it's still fun just the same. I love the Chevy orange engine. I'll bet it will keep getting faster as you get it dialed in.

litebulblsc 10-27-2023 10:43 AM

Re: Made my first pass down the strip.
 
Yep, next year.

Got the all terrains put back on it for now.
