No NOS on the Cobra. I want to be able to beat one anytime not just at the track. Also, I do have forged pistons but the rest is stock. Are you running the track day at CSW all three days? Wait a minute, didn't I already hand you your ass in a drag race with my little old Cobra?
J/K. I know I had better tires than you and I read that you got some new drag radials. Maybe we can run again at the next street legals in May. I'm going to try and get the Chevelle done by then too so I can try and get into the 9's.

Case in point; In 1988 I built my first 400 with a 5.7 rod --rod ratio around 1.56. In 2006 I pulled it down and the piston skirts were PERFECT. No sign at all of undue loads. I drove that engine hard ( to 7200 rpm ) and it was a daily driver.
I think and know the rod ratio of 1.58 will be no problem.

I did some more research after your post yesterday and found that the 347 still has a better rod ratio than my 454 does. That made me feel better about a 347 because my 454 came out of my brothers old '85 Suburban and it had over 200,000 miles on it when I rebuilt it. It still had the hone marks in the bores so I didn't need to bore it out. I just had a fresh hone done and it was good to go. I also won't be running it very high because I'll be using my same Crane 2040 cam that only has .498 lift with 220 at .050. It only pulls to 6000 rpm so that will help with longevity.
