Hi. I just put in a 3.54 rear end with a stock 350 (replacing a 2.73). Seems to me the engine is working really hard at highway speeds. I love the way it drives between the red lights but hate it on the highway. The engine is doing about 3,000 rpm @ 73 mph and it's really working hard at 80-85...
Recently, I had the rear end of my 1986 automatic converted from a 2.73 to a 3.54. Everything was successful. So now my speedometer doesn't read correctly. I figure it's about 20 mph off. Can anyone tell me what "driven" gear goes on a 1986 with a 3.54 and does anyone know where I can even find...
Today, my baby went in for surgery. They're taking the 2.73 ring and pinion out and replacing it with a 3.54. I'm nervous as a cat. When I saw all that had to come off just to get to the differential, I could no longer watch. I can't believe I'm that attached to a C4! I trust the guy that's...
I currently have a 2.73 rear end installed and have been going back and forth for the last 6 months trying to decide if a 3.73 is worth the expense at Ecklers or Mid-America. They want about 1800 bucks (including core) for the entire assembly and I'm OK with that as long as it gives me the SOP...
I'm getting a rattle that drives me nuts under two conditions. When the air is off and I give it gas while rpms are low, it sounds like one of the parking lights are rattling. Checked them, even went as far as to remove the front facia to tighten them, but I still get the vibrating "rattle" (I...
For 2 years, I've agonized over whether to restore my 86 vert or let her go and get a C5. I have a new engine with about 3,000 miles on it and mechanically, it runs great. And I don't want the car payment. So I've finally decided to paint, replace the top, and re-do the interior. Problem is...
I have a rear speaker from an 86 vert that isn't working. I've done all the troubleshooting and I know it's the amp. The metal box the amp is encased in measures about 6" x 3 1/2" and I'm told it's "the old style amplifier". Every source I've tried tells me they fix the newer style amp (which is...
My entire parking light assembly is loose on the passenger side of my 86 vert. The whole thing vibrates when I get to a certain rpm and it drives me nuts. I couldn't find anything in the FSM about how to access it. I don't know if I have a bracket broken or loose or what. It looks like you...
Honest, I'm not stupid (although I feel like it) but I went to change my wiper blades today and realized I didn't know how to get the existing ones off! They're the "pin" type where each end is spring loaded and there is a pin running through the main hole of the blade. Could someone please...
Hi. I've got an 86 and I want to get my dash cluster reconditioned. It's not in bad shape, just missing a few lines on some of the numbers and I've got a dead spot between 30 and 45 mph. I see it offered at MidAmerica, Ecklers, even on Ebay. Some say it takes 2 days, some say up to 6 weeks. I...
I want to replace my tires on an 86 vert (P255 50R16). I have 2 Centennial Interceptor ZR-X tires (I have no idea who makes them) on the front. They're getting pretty brittle. I have 2 Mirada Sport GT (99V) on the back which I kinda like. I know these are made by Yokohama. I've always owned...
I have an 86 with a new L98 engine. The fan works fine, coming on at about 175 which alot of you may think is low but it works for me. Normal operating temp is 200 - 220. But when you turn the A/C on, I'm told the fan is supposed to come on automatically, regardless of temp, which it does not...
86 L98. Can anyone tell me about the auxiliary fan (not the coolant fan) ... the fan that is in front of the radiator. I can't find anything about it in the FSM other than it gets its power from the same circuit as the coolant fan. The fan runs from the time you turn the key until the time you...
About a year ago, I bought an 86 vert off a guy who had blown the engine when he kept running with 0 oil pressure :duh
Anyway I had a brand new LT1 put in the car (not a short block - a whole new engine). Mechanically, the car runs fantastic. I'd really like to get a little more HP by getting...
Hi. I'm a newbie and have owned an 86 vert since October 07. I bought it from a guy who blew the engine by driving it after the oil pressure dropped to 0. I got a good deal and within a week had a mechanic drop a new L98 engine in it. The car runs just fine, except for the "service engine soon"...
