I'm putting a 400 turbo in my 67 and I have a 350 engine, is the any modifications I need to know about? will everything bolt up with no problems? what do I need to do? Thanks in advance

 

Depends upon what options the Camaro was born with.
If a true SS, BBC/SBC with automatic, then already there.
If base model, she came equipped with PG/3-spd/4-spd, then the trans crossmember will have to be changed for a THM400 unit and a shorter driveshaft.
Also, kickdown switch on carb throttle linkage.
Detent plate of shifter will have to be modified for access to 1st gear manually.
Longer trans oil cooler lines.

 

its a true rs and had a 350 with a powerglide

 

Here's the RPO M40 from the 1967 AIM:
Gives an idea of parts needed.

 

RS Pkg is an appearance option, could be gotten with a L6/3-spd manual.

 

looks good thanks
