273 blower cam

garage door was closed so kept it short. this was about a 3k rev, next ones won't be so pussyfied. has a lean spot that needs addressed and possibly a locked out distributor or more advance. tire smoke to follow once backfires stop.
car feels like it has a larger engine with these heads. very impressed

Hell yeah! I think it sounds great! Now that's a 4.71, right? I think I would do everything I could to NOT lock out the timing. JMO.
