10k miles on it. Everything is in great condition, i would recommend buying a ring set but other than that no issues. 9:1 compression ratio. I ran 14psi with a kenne bell 1.7l, stage 3 heads, stage 1 cams. Made 449 rwhp and was very strong. Head gasket issue / arp studs backout out is why its apart. $1500 obo.
