Project 4 Eye

Thermactor,, a road block in you exhaust port that is holding back 25 hp..whole thing will be ground down & the ports opened more.. time to grind away. The valves, lifters, cam is all real nice. The cylinders still have factory cross hatch, will hone & re ring & gasket the whole engine. pretty strong to begin with. been on the cliff about heads & cam but since its only 91k 1owner car jus gonna make nice corner carver

Lifter valley looks pretty clean. How was the inside of the pan ?
the car is a 1 owner 91k orig miles. Have the oil change book the guy changed every 3-4000 miles since new. The whole engine is excellent. Cosshatch still in cylinders-no ridge..not 1 thing in pan on plug magnet. It rotates so smoothly. Just ordered rebuild kit, rings-bearings-gaskets. basically going to put it back to new except port the heads a bit.
 
Ok, many days later, heads done, removing that thermactor giant bump takes some time. Really opened up the exhaust ports, Going to estimate 20% more flow, gasket matched intake & exhaust gaskets & mild port on intake side
My cam is split duration to help exhaust but now its freed up & especialy with header to muffler-dump no more smog & cats. Time to re clean & paint. Pulled 68 into its bay & now the focus is put this 302 together & being on the road by Sept 183 GT head p.jpg83 GT head p a.jpg
