Hey guys so im being forced in to an engine swap. My tranny on my v6 blew and so im quickly re building my 350 I had lying around but it occurred that for the transmission idk if I have a mechanical or electronic speedo. Its an 1987 Firebird base. Any help will be greatly appreciated!

 

You do know that the trans is different, right? In 87 gauges should be electronic, but I have no experience with the v6 variants. If you're going v8, I would think you need to get all the v8 stuff, harness, buffer and speedo gears for the rear ratio you use.

 

Yes I’m aware, I’m getting a trans from gearstar, fully loaded. So worse comes to word I’ll do custom gauges but I think it’s electronic?thats what one of my parts guys said but Im not 100/100 we will see when I rip it apart I guess
