Thanks OCMDGTO! This W72 is a good and careful rebuild (not blueprinted like an NHRA stock class racer) with good quality forged pistons and rods, careful finish hone on the cylinders for moly rings. There is no head or manifold porting, let alone any port matching, smoothing, casting flash removal at all. It's a low compression pure stock type build with the benefit of factory RA exhaust manifolds and Pypes 2.5" mandrel headpipes. The exhaust system is a distinct improvement over stock by 10 hp/lbft. If the engine was built with the max allowed compression (8.1 + 1.5 = ) of 9.6 to 1, it would make in the 380 hp/470 lbft range, the cam being the limiting factor.
