Problem with my L69

I just overhauled it. Now it sounds like my lifters are clacking around 3000 rpms (just before it shifts gears). Plus it runs hot (230 deg.) if I don't keep moving and when it gets up to that temp the oil pressure drops to 15 psi unless I have the RPM's around 2000-2500 RPM. My performance is gone and it smells like it is burning oil but I can't tell from where. It has 150 miles on it since the overhaul. I changed the rings, pushrods, bearings (main and rod), timing chain, and all the gaskets including valve seals. I also changed the radiator to a single row radiator but the single row is as wide as the 3 row. it has a 190 deg. t-stat. It runs fine, except the performance loss. A friend pulled the distributor out without marking it so I had to go tooth by tooth until it started. It idles high (1500-2000 rpm, 1000 in gear) but if I retard the timing then it won't idle at all. My timing is supposed to be set at 6 deg. BTDC.

This isn't the first time I've rebuilt an engine but it is the first time I had so many problems. Any help would be greatly appreciated.

Thanx,

BOZ

Yeah the timing is what I was thinking also but I never really thought about the cam. Why the cam? Thanx for your help.

i meant timing on ignition and cam, not to check the cam, but thinking about it that may not be a bad idea to see if a lobe went flat on you.
