Well... Doing it yourself or paying someone?

Start with intake and exhaust.

Offy intake manifold: $200
Holley 390 CFM carb: $350
Holley 500 CFM carb: $300 (I'd go 500)
Langdon split headers: $270
Exhaust: $500-750
Cam and springs, cam gear, gaskets: $500
Head work: $750
HEI: $100

That'll get you by until you're ready to go the next step.

EFI: FITech throttle body EFI is roughly $1,500

Now you have a base to throw parts at:

SPA Turbo Manifold: $750
Turbo, piping, etc: $1,000
Intercooler: $500
Meth injection system?

What about the trans?

700r4 plus stuff to make it work: $700 if used

Rear end? $1200



Lot of variables and lots of steps here. I started with the HEI, then exhaust, then did the intake and carb. Recently the cam, etc. My car skoots along pretty well now but I know I need to do the trans next. I should be good on the rear end for a bit. Next winter will be EFI. Then the following will be the rear end. Final step will be the turbo.

All in stages so my wife doesn't complain too much.


All in you're looking at 9 grand if you do it all yourself.

It's not about the power levels or the money for us. It's about the journey more than anything. In the end I'll have a very unique 68 Camaro that looks great, runs great and will be about the same horsepower as a stock 396.

...but I'll guarantee you that I'll have a lot more people checking out my car than the 396 guy will at the local show or cruise.
