Yeah, I ran my car for the first time at Prarie hill dragstrip in east east Waco. I spent the past 2 weeks prepping my car. Took out anything remotely resembling an A/C, and also did the smog pump. Plugged the exhaust manifolds, etc. Only thing left is the A/C and smog pump compressor things that the serpentine goes around. Haven't gotten the new shorter belt. Also I removed the passenger and all of the rear seats. But this is my timeslip:

0.960 - react time (Wasn't worried about reacting. )
2.510 - 60 ft.
10.556 - 660
79.36 - MPH
16.487 - ET

This was my best ET time. But I pulled off a 2.447 60 foot in another run. This was surprising considering the fact that I have a 2.73 NON-posi. But, I was fairly satisfied with these times. Obviously by the look of my MPH my upper-end is horribly failing! I let it shift at 4300 RPM roughly. My car, for the record, is a 305 TBI with mods in my sig. Considering these times compared to other cars, they are horrible, but for an almost ALL stock TBI, I felt pretty good. The other thing is I got to hang around with this guy and his dragster that ran consistent 8.80's in the quarter. It was awesome! It could do full quarter mile burnouts! He had something like a 598ci big block!!!! Normally aspirated of course. But then he lost his wheelie bar wheel on the track somewhere, so we went to look for it in his golf cart, and decided to run while we were at it... His golf cart ran a 65.XXX at like 14.63 MPH! He had a 60 foot time of like 4.5X. It was funny! But I had a great time, and look forward to improving my times for next time around, which should be this saturday, if all goes as planned. What are ya'lls opinions on my times? Thanks, later,

BTW, the two times I had someone next to me, one was a NEW bullet mustang, that ran a 15.3 and a 60 foot of 2.4 which was only a tenth of a secong faster than me, and he had posi and a 5-speed. The second time was a chevelle dragster that ran a 13.3. It had full slicks too. I thought it was going to be faster, anyway later,

 

Have you done a tune up lately. Seems like you should be a little faster.

 

I thought it was a pretty good time. For what I have. What involves a tune up? Like oil, and all filters, or what?

 

Try shifting manually and holding first gear to about 5000rpm or when you feel the power dropping off. This should help a little. A good tune up includes spark plugs, plug wires, distributor cap and rotor button. Then you could do the ultament tbi mod described in the tech articles, do both one and two. I did it and picked up 4 tenths in the 1/8mi. I went from an eleven flat to a 10.567 and picked up 4mph also. This is with an otherwise stock 91RS. the only other mods are msd plug wires and I cut the bottleneck out of the stock air cleaner snorkel. I want to see how much I gain in the quarter butt I have to wait till an opportune time. the closest 1/4mi. track is 120mi's away.

Thanks man, but ironically I thought that would make it run faster also, so I did exactly what you said. Powershifted it to 5000. And that run I ran a 16.7. So I don't know. But that was the time I ran my best 60'? I dunno, maybe I will put it in first, let it do to 5000, then put it in drive. But I just recetly did a tune up, of all that you said. But thanks anyway.

 

alot of us here don't have brand new engines....that makes a big difference....

 

did I say somewhere I had a new engine???? My car has 144,000 on the clock????

 

Call boneyards or buddies and get a lower geared rear end, that will help ALOT!! Trow away the stock TBI and get Edelbrock Performer and a 600 cfm carb, you'll be low 15's or high 14's for maybe $300 if you get lucky with the finds. I know cause I had 120,000 on my 305, did the rear gear swap to 3.42/posi, then induction mods above-pulled 2.04 short times on radial tires and 14.8 in 1/4. Not fast but not to bad for worn out 305 and I only had $200 into the change over.

 

Yeah, that's a good idea. I was going to do everything that you mentioned. But except with 3.73's and a demon 750 carb. On other applications I have seen. That carb has worked wonders. Probably a little more dough though. Oh well. Thanks though man,

 

I was gonna put in some 3.73 or 4.11 out of a S-10 into my rear, but after all the problems I'm having and doing stuff twice, I'm just gonna order my 9" and be done. It makes me mad cause my buddy is a tight *** and never spends any more than he has too, example: in the 12 years he's been racing at the strip he's never spent more than $25.00 for a boneyard tranny, throwas a B&M shift kit at it, then the damn things run great till he sell's car 1-2 years later. I sink $250.00 into my tranny (convertor and transgo shift kit) now the clutches are slipping 1 week after installation. Back to the 305, if yours runs as well as mine did, people won't believe you've got the little huffer. It was fun while it lasted.

 

Yeah, I understand going straight to the 9 inch ordeal. But you know, I aint rich right now, so I'm taking small steps. But, I would love to keep that 305, run low to mid 14's and tell everyone its a little mouse, but I just got my 350 block, and the sort. Yet it isn't done yet, It is coming along, and soon I will do the transport. Can't wait, but thanks man,

 

If you switch the tbi to carb won't you also have to get a new distributor and the kit to retain use of the torque converter lock up? (when the computer stops seeing input from the tbi setup, you'll lose all computer advance.)

 

I have a 92 RS with a manual trans. In May I turned a 15.219@89MPH with a TBI 305.
Mods: Hooker shorty headers, 3" high flow cat, Hooker SC cat-back, 3.42 gears, posi, 180 deg. thermostat, new plugs, new wires, new cap and rotor.
Running stock air cleaner with K&N filter, stock TBI and manifold.

89WS-6,
My advice is mod the rear end (posi w/ 3.27 or 3.42 gears) and finish the exhaust (headers and cat). Then go from there. Also put it on a dyno to see when the power peeks. My fastest run so far was before I dynoed and I was shifting 500 to 1000 RPM too soon. That may be less of an issue with your automatic.

 

True about the shifting before power is made. But with the TBI, it cannot feed up into the RPM's. Just wasn't made to do it. At least with the stock injectors and all. I can rev it up, but it just decides not to go anywhere above 4500 RPM. The carb should do that. But dunno. So I will experiment and get back to ya'll.

 

For a 305, a 750 carb would be a huge overkill(it will bog like hell in low rpms). It will also be too much for a 350 that doesn't rev above 6500. You would be better with a 650 double pumper and performer rpm air-gap manifold. If you are only shifting at 4300 now, 3.73's will slam you in your seat, but probibly slow your 1/4 mile down, but after you carb it, they shoud work great.

Always remember: a well matched combo will work best.

 

Thanks man. I might get the 600 or 650. But, When I get my 350 built, it WILL be going at or above 5500 RPMs. So I dunno, I don't like to buy things twice. But thanks man,

 

That was true for me before I finished the exhaust. The dyno shows the engine making power to 5500 RPM where on a previous dyno it did die after 4500.

 

Yeah it probably is one reason for the lack of RPM's. That damn exhaust. And my exhaust is special. It is probably really limiting top end. So I have to look into that also. Man, everyday, I need something else to get for the 350. Damn! But thanks ya'll.
