Hello,
Im new to this forum as of today and I'm looking for some information. First let me just say that the project car that I'm building is a 1987 Z28 Camaro 305 car. I recently put a 350 engine in the car. One of the first problems im running into with the car is the 85 mph speedometer. I'm wondering is there a convertion kit to convert these to a larger speedometer or do I have to go aftermarket with a seperate gauge mounted somewhere else in the car? If there is a convertion kit, what does it take to install it and where is the best place to find one?

Thank you for your help in this matter, and I will see ya at the track!

Welcome to the boards, Mark!

If you're looking for a speedometer that reads higher than 85mph, you can simply swap in any cable-driven 145mph speedometer from a Z28 or IROC-Z (I presume that yours is still cable-driven - from '85 to '89 they were cable-driven, and they went electronic in '90 IIRC). It's a direct swap if my reading serves me, but do some searching on here to get the definitive answer.

If you're looking for a gauge that is physically larger, I do not know what will mount in the stock location and what won't.

Hope this helps you out, and someone please correct me if my info is wrong
