305 cleanup
I have been told conflicting opinions on "upgrading" a 305...where upgrading in this case is mostly interested in a slightly increased lope in the idle and improving the idle sound of the car. One tells me I could do a new cam & lifters and there is a chip to accomodate it and a second tells me the 305 is maxed out & can't do much with it.
I looked for almost an hour on thirdgen.org and could not find anything on this...thx!

None of the stock 305 configurations delivered in thirdgens were "maxed out" in any way, there are lots of improvements that can be made.

Re: 305 cleanup
Thanks....What would be recommended to improve the idle sound of the car? Prefer not to tear up the computer...maybe a chip change with a cam change?
