I searched and couldn't find any info on the head bolt kit from ARP #123-3703, purchased from a very reputable vendor....says for 85-87 GN. My problem is that the center two bolts (the longest ones) are too long. They measure 4.5" from the top of the cap to the end of the bolt, and bottom out...

My speedometer has been making noise and jumping, so I'm in the process of lubing the cable. I have the top end lubed, but how does the rest of the cable come out? I take it it's not from the tranny end. I am under the impression that the adaptor between the two cables should unscrew from the...

Before I put the car away last fall, I noticed the speedometer cable making a little noise and I was wondering what is the most popular lube for it.

My combo in in my sig. What kind of real world gains would I see by going with the 60# injectors, other than lightening my wallet by several big bills? Would I really see much more out of my combo, at the track? My '44 and blues seem pretty good, possibly a touch lean at the top end, but...

I know that there have been posts before about getting knock only when the tires break loose...... false knock, or real knock? Has anybody found a solution to the problem. I was wondering if it was mild wheel hop and with the close tolerances of the driveline, transmits it up to the engine...

I was wondering how easy most drive shafts are to get out. I've had mine out a few times and it is very tight.....with the car on 4 jack stands, I have to jack up the rear end, and it barely comes out, I still have to turn the shaft to completely disengage the u-joint. The reason I was asking...

I have aquired an '85 Buick Century Limited, with the 3.8 FI engine. I know it's not a turbo car, but bear with me.... I know these engines.(see sig.) my problem is that when the car sits after it has been run (hot) the fuel seems to vaporize in the fuel lines, because it will start right up...

I knew I just needed more track time and the correct, dependable parts, and it finally happened at the last race of the season arround here. The car went 11.91 @ 112.46 mph and had a 1.70 60' time. I was pleased, all this with a 111k mile car and I had more boost to play with, but ran out of...

Who cleans injectors, or is it worth doing? I have a set of blue tops with 35k on them, or so and am having fueling issues and want to go through the injectors. What does it cost? I should upgrade to a set of 50s but don't to deal with the cost of that this season. Any input would be...

I need ideas on finding the cuase of the low block learn multiplier numbers, they read about 102. The car seems to run OK. I have adjusted the fuel pressure to the recomended 45 psi (T+ instructions) and it's the same. The INT numbers stay about 128 or so and the O2 numbers are all over the...

A friend of mine has a tube chassis 57 Chevy pickup with an old school, high reving 301 V8 (de-stroked 350). He has all the good parts on the truck and is shooting for the 8s, he wants to know who to talk to for a twin turbo setup for this engine. I know this is off the wall, but someone must...

I have found a 80s TA with the GNX style wheels, but the wheels are not on the car correct, one side has the wheel with more back spacing (less dish on outside...correct?) on the front, and the other side has that wheel on the rear. Which wheel is the correct front wheel??

Need Turbo help....Rebuild time??? I purchased a new TE44 about 4 years ago and it now has about 5300 miles on it. I know there can be some "up and down" play in the shaft and should no in and out play in the shaft that is noticeable, I was checking the play in my turbo because the car is...

Is there an easy way to tell if I have a high pressure waste gate or a standard one. I bought the TE44 from Postons. If this one isn't going to get me over 20 psi, I better start shoping.

For keeping an eye on things day in and day out, and for fine tuning at the track, is the EGT meter the way to go? I have T-link for the track to monitor things, but want a different, more precise way to tune that I can use easily. It's either EGT meter or Scan master. Which will fit my needs...

First off, sorry for the long post, I just want to get all the important info on here the first time so I can get an accurate, quick response. I am looking to change my chip, my setup is a stock short block except for the cam, it is a Weber Racing grind-Comp Cams 206/206, with new valve...

I was wondering what your opinions were as to which would be the best money spent. 87 GN, TE44, blue tops, Red's XP fuel pump, adj. regulator, Terry Houston downpipe, Kenne Bell exhaust, K&N, power plate (to be installed) SCM alky, Comp Cams-Weber Racing grind 206/206, thrasher 92 chip and...

I am looking to upgrade my stock intercooler, my question is, who has the best bang for the buck, I want a stock location, intercooler and a half. I had my sights set on the CAS unit, but..........well, you know. It seems there are a few new entries to the stock location intercooler market and...

I finally found the cause for my knock trouble in first gear. The car is leaning out due to tire spin is all I can come up with. I went to the track with slicks for the first time and no knock. I put the street tires back on it and capped the exhaust and it was back to severe knock just as the...

I have a question for you all, do the 275/50/15 BFG Drag Radials fit on the stock 87 GN wheels and without rubing on the frame? I have a set of BFG Radials, 265/50/15 and they just fit, but I need more traction than they can offer. I think the 275/60/15 will be too tall and hurt the...
