WHat year engine did you put in? They dropped the compression quite a bit on the later engines before EFI, and also had retarded cam timing.
You should start at about 8ºBTDC on the timing pointer (not cast timing cover marks) at about 650rpm.
My timing marks on on the passenger side of the timing cover. You will see the toothed timing indicator on the cover over the balancer. There are also several lines on the balancer, use the thin scribe line. Clean and mark the timing marks before setting timing to make everything easier to see. i put a small mark on the 8 deg point as a reference. I run the stock 8 deg timing in my manual tranny truck. Any more and it likes to ping under load.
