I'm a relatively new member to this forum, and I've really appreciated hearing all the things members are doing to enhance the performance of their C3s. I have a '75 350 L48, and, as probably most of you know, the '75s were at the low end of the C3 hp curve as Corvettes go. I want to do some 'minor' top half enhancements to my engine -- someday maybe I'll get a 383 stroker, but it's not in the near term plans -- but I'm not sure how to proceed. I gather getting new aluminum heads and a performance cam would be a good thing to do, but the mechanic I use wants me to get flat head pistons and a host of other engine internals. From what I've heard on this forum and heard 'around' the Edelbrock Performer RPM heads are the best, and Eckler's has a small block 260 High Energy cam that looks like about what I'm looking for. But the Edelbrock heads may be overkill for what I want, and I'm not sure what all else I should get along with heads/cam, anyway (push rods, rocker arms, etc.). This is almost certainly not a 'new' topic, but any advice ya'll can give would be appreciated.....I'd like to spend no more than $3K, but $2K is more realistic, and I'll do most of the labor...
