how high will a 273 rev.

:pirat: Well my 2 cents, on a side note: I put $6000 in a 273 back in the day... 1979 and my redline was 8500 and it bounced off of 9300 a few times with missed shifts with the 4 gear.. Obviously not stock ...

But out of the box if it is a solid bottom end many 273's are fine even with cast pistons to 6000, above that man be carefull! Rod bolts are weak link as are the cast pistons.

OH and at that RPM you can get into lack of oil in the pan too!
