Chevy .030 over 4 bolt main block. Scat crank with TRW-SpeedPro forged pistons. Was put together 15 years ago and driven less than 3500 miles. No ridge in cylinders and did not burn oil. Edelbrock 7102 Performer RPM hydraulic cam, Edelbrock True Roller timing chain and cover, Milodon deep sump oil pan, Melling M55HV oil pan with deep sump pick up tube, 168 tooth flexplate, and damper. The engine stand in pictures comes with it. Because of age I would recommend replacing bearings but that is all. Only reason I took it out was I have a Dart Little M 388 that I put in. Asking $2,900.00 I also have a new pair of RHS 12308 cast iron 2.08 intake 1.60 exhaust 72 CC heads with new valves, springs, & keepers. Was $1,800.00 new asking $1250.00. Would make a deal for block & heads.
