rebuild of 68z/28 engine questions..

7500 not likely, where do you plan to do that at. If planning on Racing/Street/Drag or Track then you got a LOT of work to do. But Really how often do you plan on running it in "that reality". If it is a true Car show weekend cruzer' I would think the springs warrant checking but without cycling of compressive forces and heat and cooling the negative affects of static (Relaxed) compressed would be negligible and if they were New at that time would the available stock be considered better than todays outsourced stock.

I know of locally Nine 68/69 Z owners and NONE of them are routinely spinning their 100k show car near this. They Drive differently then they Bench Race.

7,500 Yes Maybe a VERY Very Few, Please post your Videos of your Tach on your MO/DZ motors doing this on your country roads near your house.

I am not being Negative just wondering about your usage, I would think there are a bunch of Engine related things to consider If you want to routinely spin up there.
