hi tweaked250r, i also installed the same cam in my 350,it has 9.0:1compression,600 eldebrock,performer rpm intake,runs like a bear. im going through this timing issue also, my problem is if i set mine any were near 10 btdc i cant get close to 34 total, right now i have 20 initial and 34 tota;my question to you is were are you idling at without a load and in gear ? are you running a auto? do you have a stall converter? what size? i drop about 400 rpms from park to in gear so i still have some playing around to do , i believe youre talking about the lunati voodoo cam thats a awsom cam, i use ported vacuum on mine
