A few days ago, I went up to the local dragstrip (Keystone Raceway) for the first time to test out my car. My best time was a 14.6 at 92mph. At the time, I had the following modifications done to my car:

Hypertech coil, cap, and rotor
MSD 8.5mm plug wires
Regular ACDelco spark plugs gapped at 0.045
Catco hi-flow catalytic converter
Hooker Aerochamber cat-back system
Partially-gutted air box
B&M Megashifter
Custom fan setup (stayed around 195°)
Mobil-1 synthetic oil
Stock 3.23 gears with limited-slip diff
Regular air filters (no K&N yet)
Some generic airfoil

Other than that, it's a stock '86 IROC with a 305 TPI engine and 700R4 trans. Does a 14.6 for that configuration sound decent, considering it was my first time dragging?

I just built a custom ram-air setup for my car. Along with a Transgo shift kit (from Pro-Built Automatics), subframe connectors, and a custom chip (a tuned '89 MAF bin), could I be in the upper 13s? I think the shift kit will really help because when I go to shift, I literally have to let my foot halfway off the gas for nearly a second before the tranny "catches" and moves to the next gear... that's definitely costing me time. What do you think?

 

shouldn't this be in drag racing?

 

Yup.

 

Sorry about that, I didn't realize that I had it in the Street Racing boards.

 

Aww come on guys, someone has to have some feedback for me to think about...

 

I can believe that u ran a 14.6@92 with a 1985 LB9 auto. For the mods that u have I think that is an impressive time with that engine and peanut cam.
I dont know if u will be able to get into the 13 range with that cam. If u got a new cam u would be in the high 13s with those mods I think.

 

I agree , even a mild cam with say 206/210 .050 and 450 lift w 112 would make that thing cook.I have an 86 T/A and stock it ran a 15.3 @ 89.2 mph , so youre beating me by basicly 7 tenths with a cat-back. I know what you mean about the shift from first to second, it stinks, the trans-go will cure that , as will a custom chip that maked lock-up occur after 40mph instead of the stock rediculous setting. I would try the free mods listed elsewhere (open up plenum etc) and you may squeese a few tenths out of it more. But cam and head work will make you fly fast!

That's flying for a stock 305 TPI. Good work on whatever you did to move that thing.

 

I was equally surprised with my time... Whenever I got my time slip, I thought to myself, "Geez, I thought these things were supposed to run about a full second slower!"

I've definitely got to do some of the free mods like plenum porting. I'm saving that for winter (when I take my intake off I'm going to polish it at the same time). I'm not sure if anyone saw my other post about my custom ram-air, but I'll be testing that out on Tuesday when I go back to the track... that might be good for another tenth or two.

One of these days I'm gonna check the casting numbers on the heads, too. It's a little interesting that my 1986 V8 has center-bolt valve covers, when those premiered in 1987 .

 

Yes that is very intersting, I have had 2 TPI 86 cars and they both had perimeter bolt valvecovers.

U should also add some headers with a hi flow Y pipe. That would really open things up for u to. I would say that u would lose about .3 to .4 of ur time. I would do headers before anything else. Then get a new cam and some heads.

what was ur 60ft time and how did u launch ur car.

 

Yeah, I was looking at SLP headers (I hear those are the best for third-gen F-bodies) but it's hard to justify the $600 price (coated).

My 60ft time was 2.049 seconds. I launched by holding the brake and revving the car to about 1200rpm in first gear. My stall converter is still stock so I can't make the engine go much higher without moving.

 

I managed to check the numbers on my block and it turns out that I DO have a 350... one of the previous owners must have swapped it in several years ago. That explains my 14-second times, too. Here's a link to the other post I made if anyone is interested:

There's nothing wrong with the Hedman shorties and Y pipe. About $250 for the whole thing. I think they even sell some with air tubes if you want to keep that. No reason for it unless they do visual inspection.

 

Are the Hedman Shorties coated headers?

 

14.6 @ 92mph is about right. It's a replica G92 350. My buddy has a 89 Formula w/new stock heads and I pull about 1-2 on him after traction. Now that I got my DRs tho I'll wave goodbye to him the entire time.

 

P.S. Edelbrock gained me 2mph but the stupid tread on my tires kept me at like 2.2 60fts so I didn't have much to work with.

 

Sure do.

There are a ton of different kinds of hedders there. Find the ones that suit you best. Full lengths are a pain to fit so I don't recomend them. Painted shorties are $105 w/o air tube and O2 sensor bung. That's the absolute cheapest way to go. Some people have had real good luck with high temp paint if you bake it properly.
