    Original windshield or not

    Anyone know if this is the original windshield for a 1970 Z28? The car is pretty much original with the exception of the paint. 69k miles. It needs to be resealed and I would prefer to use the same glass (if it doesn’t break) if it’s the original. Attaching a picture. Thanks to anyone that can...

    Tachometer and Speedometer adjustments

    I have a pretty much all original 1970 Z28. I have discovered that the tachometer reads 200 to 300 RPM's high and the speedometer reads about 2 mph slow. I now this doesn't sound like much, but while driving 60 mph the RPM reads almost 3500 RPM and it bothers me. The tach needle at rest is...

    TCS switch works backwards

    I'm trying to get the TCS vacuum solenoid and transmission TCS switch to work on my 1970 Z28. Vacuum from the solenoid to the distributor is controlled with the TCS switch in the Muncie 4-speed. The switch should be closed in neutral which actuates the solenoid and shuts off the vacuum, and...

    TCS solenoid wiring

    I'm in the process of reinstalling a TCS solenoid and transmission switch and am trying to find out how the wire was routed from the TCS switch in the transmission to the solenoid on the engine. Most of this 1970 Z28 with its M20 is all there and original but the smog stuff and exhaust was...

    Trunk gas props

    OK, I give. I have installed 3 sets of trunk torsion springs on my 1970 Z28 in the last 2 years and all have failed. They work for a while and then slowly loose there tension. The first set came from Classic Industries and I think were OER. The second ones from Fbodystore and the third from...

    1970 Camaro Z28 correct master cylinder finish

    I'm in the process of having my master cylinder sleeved and overhauled and need to know the correct original finish. Not sure if it should be powder coated grey or black or just clear over the cast iron. Anyone know the original look? This car is still an all original matching numbers vehicle...

    1970 Camaro console ashtray door springs

    Does anyone have a picture of the console ashtray door springs installed? There is one picture floating around that I believe originated from this site, but it's not helping me figure this thing out. I feel like it should be simple and I'm an idiot. There is one hole (per side) in the lid arm...

    1970 z28 correct fuel lines

    I'm trying to install the correct fuel lines back onto my 1970 LT1 350. The carb has been changed from the original 780 Holley to a 750 and has 3/8" outlet fittings on it. I ordered the OEM style 3 piece lines and block fitting from Camaro Central. The line from the pump to manifold isn't even...

    Need advise on LT1 pistons

    I"m looking for advise on pistons for my 1970 LT1 rebuild. Trying to build it as original as possible. They are 11:1 pistons. The bore is at .030 now and need to go to .040. I posted this question once before and was told to go with the Speedpro L2304F pistons. Problem is they don't seem to...

    Need 3927186 1970 LT1 heads

    I'm in the process of rebuilding my #s matching 1970 Z28 and found my heads are beyond repair. I'm looking for some buildable replacements. They are 3927186 heads with screw in studs and push rod guides. Looks like mine have a build date code m 230, but I'm not that picky on the date code. If...

    Which pistons to use?

    I'm rebuilding my 1970 Z28 LT1 350 and am looking for some advise on pistons. I'm the 4th owner and somewhere along the way the engine was bored to .030 over. It looks like it may need to be bored now (currently at the machine shop). I will likely bore it to .040. This is a numbers matching car...
