1970 Chevelle SS with cowl induction 454
I just received a 1970 Chevelle SS 454 Ls5 Cowl Induction with all matching
numbers and a complete off the frame restoration from my Dad. I was
wondering if there are any improvements I could make without dropping the
value? Thinking about maybe adding some chrome parts on the engine, Air
The heading for your question says that the car is an L34. An authentic L34 engine is a 350 hp 396ci (actually a 402 ci); not a 454 ci. If you have a 454, that's nice, but would not be original to an L34 car. If all this checks out, you may have the LS3 package which is the L34 without all the chrome stuff under the hood, and the LS3 engine was detuned to 330 hp. Keeping authenticity, adding chrome to the engine might make the LS3 look like an L34. As for AC, only the build sheet shows how your car was originally optioned, so a stock original AC would be fine, but aftermarket would be nice too. If the question heading was wrong, and you have an authentic 454, you could research this to see what you actually have. GREAT car, either way. 1970 was the panicle of power, as 1971 muscle cars were detuned for fuel economy.
Any "improvements" on such a car SUBTRACT value. Originality is King!
