Yesterday I was on my way home when I started a 2nd -> 3rd pull and right about 5500rpm in 3rd I heard a little poof. Ever since then I thought my #6 clyinder was missfiring although everything was testing out fine. Finally I did a compression test and these are my results:

Misfiring maybe mistaken for running lean in cyl 6 to heat up the cyl enough to melt a piston or burn a valve? Tear it apart for fun.

Los, what parts do you have that will fit the 20??

Unless he's gonna stroke it, But I thought you sold your 25 crank.

Buy another long block or buy a 25.Not work building the motor.Costs a lot plus PITA to find parts and wait for them.
