HI THOMAS : GREAT truck now and will be a greater truck when completed . Here's what I did with my 250 ( which began life as a Mercruiser 165 ) It is .030 over pistons( stock Comp ) , all new bearings , oil pump , etc., Head is cut .080 , 1:84 intakes , stock exhaust valves ,Comp Cams 268-H cam/ hyd.lifters , , unshrouded around valves , multi-angle grind .Did NOT remove intake bosses , but ground them to an airfoil shape ,port-matched in about 1 inch . OFFY intake , 1 inch / 4 hole spacer , Langdon headers ( heated )Road Demon Jr. 525 , 4 barrel mounted transversely .
The car drives VERY strong , Pulls strong @ low RPM and gets decent fuel mileage - Don't forget ZDDP additive for break-in.
