Just put the 350 back together. It is in a 73 3/4 ton 2wd pickup with no stall converter. It has -23cc dish pistons in it, its a reman motor from advance auto parts. It has 3998991 heads on it 75cc chambers redone with z28 springs. Installed a Lunati Voodoo cam in it 638-60101lk .454"/.468" lift 256/262 dur. dur at .050" 213/219 LSA/ICL 112/108 it says its a 1000-5500 rpm cam. Its got a Professional Products Crosswinds intake sitting on top of it with an electric choke edelbrock 600 cfm carb. A Wapp Distributor, looks like a MSD and headers. I don't know if the compression is too low with these pistons in it but this combo ran great on a 350 with flat top pistons. I'm not sure what to set my timing at. I think its at 10 degrees advance now with 15 vacuum for 25 total. If I keep advancing it it gets more power but its harder to start. Can someone help?
