well the coolant is rust colored so iv been flushing.. but all plugs read good I will do a compression test before blower goes on for sure 100% no doubt...
I guess i should have asked how much power can I get out of it?
The rust color in the coolant is the factory no leak that they put in there. They are like that brand new. People have whippled + nitrous 100k+ mile stock blocks with no problem. Not a normal motor when you have all forged hand built parts.
