Carputing, the makers of LT1 edit, don't have a phone number on their website anywhere, and its not listed with 411 directory assistance. My order for LT1 Edit is nearly a month overdue from the email of when I could expect it. I've emailed them 4 times without response. Do any of you who...

I've got a miss under WOT that starts around 5000 and higher, slightly lower in 4th and 5th. I know that this could be detonation, or my knock sensor getting a false reading pulling timing away. My question is about the other posibilities, like fuel starvation (doubtful), dirty injectors...

I've been thinking about a new paint job.......but white over red wasn't what I had in mind.

My normal driving routes from my house to all the places I go, I encounter alot of long right hand turns (off/onramps for instance) and I've noticed that the outside of my front left tire is near bald, and the inside still has medium tread. So, I want to put in a little more negative camber. I...

I just ordered a single mass aluminum flywheel and stage 2 clutch (stars brand, I think) from Doug Rippie motorsports, and will be coming this week sometime. My question is, every bit of work I get done on my car, the mechanic always complains to me afterward about the vette being "special"...

I've been thinking of swapping my 3.45 gears for 4.10 or higher, and in my research, a couple questions have come up that I don't have answers to. #1 Why do gear companies (such as richmond gear) sell dana 44 ring and pinion sets for $150 give or take, and when I shop for the same thing at...

I just got back from carlisle, and while I was there, I had my car dynoed. I had previously had it dynoed in stock form at 305/315 hp/tq. After a few minor mods, one of them being a Hypertech programmer, I figured I'd pick up a few ponies.....wrong. I dynoed at 295/305. The technitian said my...

I am about to buy a set of full length headers off an 85 corvette for my 96 LT4 vette. I've been told they should fit the engine no problem. I have a few concerns I need to have addressed by folks who know. #1 I don't have EGR, and I'm sure that these headers aren't equipped for EGR, so no...

My 96 LT4 heats up slowly , and will sometimes even maintain regular operating temp. between 195-215, but the second it gets to 225 it skyrockets up to 245-250 and completely fills the overflow tank to bubbling over. It does this whether I'm driving or if its started cold and allowed to idle in...

I recently ordered the "throttle body coolant bypass" and discovered it to be a waste. #1 it didn't fit right (one side was too large to fit either hose end) #2 the modification didn't require any kit at all. The hose that runs from the area at the top/right of the radiator over to the left side...

Friend of mine asked me a question I couldn't answer. He's a got a 6 speed in his C4, and the car shakes a bit when he slips the clutch to start off (like from a stoplight). He either has to really goose it, or not use any gas when he starts off to not shake. Sounded odd to me, any ideas?

I have headlights that are very moody on my 96. The left one will work most of the time, the right one never works. When I spit the lines and run both off the left wires, they open half way. Currently I have both sides cut and am operating them manually. Do I need new motors? Are the gears...

I have a 96 LT4 Coupe as a daily driver that I want to use for an occasional trip to the track/road circuit. I've got some pretty good aftermarket brakes on there, but I don't know about the fluid. Is racing brake fluid bad for street use? If it is, I'd like some opinions on how well DOT4 rated...

New owner of a 96 LT4, and I want to put long tube headers and flowmasters on my car, which is going to be catalytic converter delete (I always gut them anyway). I know Doug Rippie offers them, does anyone else? If anyone knows how hard they are going to be to put on , please let me know. I can...
