⭕ 1967 GTO YS code 400 built by Paul Spotts. Correct for 67 GTO with TH400(trans not included), but will bolt right in any GTO or Early Firebird or even Fullsize Pontiac from 1970 and earlier. Block is bored .020 and honed with torque plate - forged Sealed power pistons, chromoly rings, resized stock rods with ARP rod bolts, factory N crank cut 10/10 and balanced.
