How to determine a safe red-line?

I wouldn't push a stock 360 much over 6000 as it has a longer stroke than the 340 which red lines at 6500 stock.

LOL....you guys need to get outside more often...got stock 360 ...with that really long stroke..LOL.....running 7000+ thru the traps....

last year at Bakersfield it was cranking 7500 rpm .....

lets see..the short block was assembled back in 2006.......

I know ...if it was a 340 it would be a full second faster....and turning 9000 rpm....LOL
