Thanks took it to a machine shop. diffrent from the one that did it originally. They told me there are many things wrong with the engine. To start with it has forged 11.5.1 pistons and they said that the block was bored 30 over but it is 7 to 8 thousands over clearance.they say it sould be 3 to 4 for the forged pistons. which is to much.so i need new pistons.Said it had tripple valve spings in the 502 heads which they say is to much and that it will eat up the hyd. cam.they say they can fix the engine and do a roller cam change with roller rockers and chrome moly push rods and a stud girdle.plus fix rods with new rod bolts for about 4000.00 wondering if that sound right. would really like some help with this it is in my 1969 yenko camaro clone. the motor was just re built 1500 miles a go and took it in because of the water and oil leaks and they found all of this . the first built cost 2500.00 The motor was also balance but had a bad vibration at 65
