Tom - I didn't mean to hassle you directly. Sorry if I came across a little strong.
No harm done. I guess I know enough to be dangerous. I wish I could build a killer OHC motor, for that matter I wish I could keep my cammer. I'm outa space, time and money to keep two 'birds going. The purchace of a 2010 Camaro may be pushing my cammer out of the nest.
