May want to check the weather strip for leaks etc. before purchase. First do a visual inspection, with the top off, and look for rips and tears where the top meets the glass. If it looks OK go to a local car wash. I normally wash my vette by hand but have on occassion taken it to a brushless...
For the 92-93 LT1 corvette the Fuel Injection offered was a Multiport FI where (and I think this is how to describe it) each nozzle on one bank (side) will fire regardless if the intake valve for that cylinder is open. Tis will happen as long as one valve is open on that Bank. In 1994 to 96...
74 was the last year for the big block 454. IMO That in itself is worth a second look if it's a # matching and it sounds like it is. I took a ride in a friends 74, 454, with 4 speed and totally stock (don't know what gear ratio in the rear). It was not the tire shreading monster that I...
Hey Doutdoor. See if Brady of Brady's transmission is still in business there in Auburn. He does tranys and rear ends (I think) and is very good and priced right too. Don't ask how I know this guy being in New York. It's a long story...
Thought I would throw this into the discussion. This is from Graham who frequents this sight often. I think something like this should be a part of this sight if possible (are you listening Rob) it is that well presented.
Again, I did not put this together, but I wish I had it is that good...
I think Sothpaw is correct. Autocrossing does put a lot more stress on the internals than 1/4 mile drags. My thoughts are this: autocross will use the compression to slow down the vehicle, I'm not sure but I think this puts stress on different parts of the rotating assembly. Then all of a...
Hi Topless. I have a 92 Coupe that I have had for 2 years now and as far as I know it is completely stock. I measured the outside diameter of the pipe going into the muffler and it measured 2 3/4 inches. Like I said, as far as I know it is completeley stock. IMO, the stock diam. exhaust is...
Thanks for the replies, I am now thinking of only minor mods to suspension such as increase sway-bar diam. size etc. From what I can gather, and BTW this sight is an excellent knowledge base, the 92 coupe (stock) suspension already has fairly stiff springs as is. Not as stiff as the Z51 but...
For a 92 coupe auto with the standard suspension (no Z51) can I upgrade to the FX3 shocks? Is it worth the effort to just replace the shocks or should I upgrade to stiffer springs and sway bars.
Has anyone tried Extrude Hone on cast exhaust (Ram type) manifolds? I think this process will open up each exhaust runner and allow a lot more flow. No harmonic benefits though.
Stallion. As mentioned above, the motor mounts, under normal condintions will not be a problem. However, older cars and cars with major modifications done to the engine will stress the motor mount to the point of failure. Some fail-safe measures I have seen on high HP engines is to mount a...
Thanks vettlt193 I appreciate your experience. I will most likely look into the 1.6 intake and 1.5 exhaust rocker swap as a winter project. I have replaced normal stamped rockers before and it is a snap. Is there any trick to doing the roller rockers?
Had my 92 auto with 2.59 gears up to 135 mph indicated. It got there rather quickly and still had more pull left. I chickened out and let off at 135. Things start to happen really quick at that spead and it was not a closed course. No mods to the engine other than K&N air filter.
A question to the masses but mainly for the LT1 type engine. I have heard of swapping a roller rocker with 1.6 ratio in place of the stamped 1.5 ratio non-roller rocker to increase HP. I have read that Crane Cams has the only replacement type roller rocker that will fit under the stock valve...
A few months ago I took the vette in for its yearly inspection. A friend operates a service station close by and he has been inspecting all my cars for many years. Since this is the first inspection since I purchased the car a year ago I figured I would stick around to take advantage of...
I believe the C4 change oil indicator is set at 7500 miles but I should never see this go on and here is the reason why. For those of us who store our vette. In a recent article on "storing corvettes" one of their suggestions is to change the oil/filter right before storage. This will prevent...
At the risk of asking a question that I'm sure has been asked many times before. I have a 92 LT1 coupe with auto that is completely stock and like many of us, would like to increase HP and TQ via the CHIP. Is there a best chip for the non programmable 92 computer? I've seen and read ads for...
