That engine seems so much bigger in the little Merkur engine compartment. I guess it's because I'm used to workin on my tbird with the same engine, but a engine compartment that will fit a 460 comfortably.
They're great little cars to tinker with...Please tell me you bought a 5-speed!

Every C3 I've ever touched was total crap!
Oh yeah and if you want to fix the boost to a lower level really cheap... a yellow wire splice connector in the vacume hose should perfectly allow 15# of boost.
