After I shipped it back to Seattle/Ft Lewis I had to replace a burn exhaust valve so while the head was off I ported it and had the DC larger valves installed. Put a 270 degree LRE Roller cam and roller followers. Made the intake manifold accept a Holley 350. Put the LONG header on and 2.25 pipe all the way out back.
Net effect was a 15.88 1/4 mile all day long.
