Will this bore clean up, magnum head content too.
A car I bought about 5 years ago had a 360 in it. The plan was always to put the big block in it and maybe put the 360 in the car in my truck. I never drove the car much, it ran real good, but at cruise I always thought it smelled a little funny. Compression test had all the holes around 185-190psi.
Pulled a head after poking a camera in the spark plug hole. was thinking maybe the head was cracked but I think it might be another present from the previous owner. The short head bolts were pretty easy to break loose with a 15" ratchet. The long head bolts were tighter and actually popped when I broke them loose. Gasket was 8553pt.
So the bore had coolant sitting in it and it has this black raised stuff on it. I already hit it with a little scotchbrite and some penetrating oil, it's coming off but is really slow going.
What will clean this off? A brake fluid soak? Trans fluid? I don't wanna just rotate the motor over and let the rings scrape it...
