Hey gungho, the post I posted the other day was meant as a friendly post. If you had been close to Texas and where going to be at a track close to me I would have wanted to meet up and bullshit and do some racing. As far as mine being a 79 and trying to compare to your 70 Z-28, look again, mine is a 72 not a 79. Sorry you took the post as an insult or however you took it. As far as me thinking my car is the fastest in Texas, not even close but I have alot of fun with it. As far as me needing to move on, nah, I think I will stay right where I am. I doubt with you being in MA. and me in TX. we will ever meet up but never the less, have fun and be safe doing it. OH, and to put my opinion in on the Pro-Comp heads, I have not ran them so I have no personal experience but I do have a buddy who bought the bare casting and said with good components in them they are OK.
