Well, It sounds good to me but I'm definitely not the old toot to ask. I have a 4.3 in my work truck and for the last 141,000 miles it has been a real little work horse. Prior to this one the last Chevy I owned was a mighty 235 in my '51 four door and that was in 1954 (give or take).

TCC probably wouldn't be too offended If you asked to talk to somebody in the department and maybe see if they would permit you to sit in on a class.

I'm assuming they have classes that deal purely with engines but I'm in no way certain.
