third gen swap

[UR50SLO]

im currently in the middle of a gn motor swap in my '90 camaro. got the motor mounts from hrpartsn'stuff, i'am very pleased with them,it fell in there. do i need to upgrade my dash or can i get away with the stock gauges? also do i need to notch the frame for dp clearance if i have stock headers on it?

If you use your stock dash make sure you use the stock "Camaro" sending units for the gauges. If it was a V8 car you'll need to do somthing with the Tac feed as it won't read right with V6 pulses being fed to it.
All the gauge wires come from the drivers side bulk head (RH side of booster)

Notching the unibody sure makes it easier for the downpipe. I notched mine alot to fit a 5" downipipe that blends under the car to dual 3" with Ultra flow mufflers.

I'm sure 88Z or I can answer any questions you got.

thanks for the info. very clean engine bay- i like it. im already running a autometer tach-before i just plugged into the msd box. what do i do to make it work with the new motor?

 

[UR50SLO]

In the back of the tac there will be a switch... just select 6cyl and you should be good to go off the white wire on the Buick Coil pack.

No real need for MSD on our stuff. Some of the big guys run distributers but I've got no Idea why to be honest. I'd go coil on plug before going back to
a dist.

Same here sbc/nos to 3.8. The swap was one the best things I did to the car. I'll be happy to help with questions too.

Yeah, My firebird has a factory single fan setup and I made it work. If all else fails, you can just wire it up off 12v ignition and run it whenever the car is on too. But the GN Harness has Fan Controls in it.
