searched all the oilpressure problems from old post, and havnt felt very sure about what is the problem or could be. This is my first built bbf and havnt had it to track , so its hard to no how it will do in 1/8 mile, but dont plan on finding out till something is done to help. I can accellerate easy in second gear around 3500-4500 for under 6-8 seconds or so and pressure will drop from 75 to 50 and bounce form 40# or so. This is after driving 3000 rpm or more for a minute which probably doesnt help. Have a canton fox swap pan and pick-up with canton screen windage tray, melling HV pump, 3/8 clearance pickup to pan. Had to move little bracket back one hole to where the cutout was for on screen. Heard it done before and thought that was weard since they were the same company. Might be flexing??. 3.5 on mains and 2.5- 2.7 on rods. Done all the oilmods to block and gaskets on right and holes not blocked,roller lifters in right. running 25/50 VR valvoline, no vacuum pump. Seems like pans being sucked dry and one quart didnt seem to help. Might be crank pulling oil up, Might pull intake and put in one restrictor to see if it helps. Lifters seem fairly tight in bores so didnt sleeve. I guess the restriction from them would of been good. Can still put in restrictor pushrods i guess. also first time i seen pressure drop it had pressure around 30 while slowing down and hit brakes hard and went to 0. Oil went to front of pan. Doesnt have a crankscraper of any kind just a little like flap in back to help keep oil from climbing up. I fairly sure it would make a 1/8 pass for 6 seconds at most but dont want to be wrong I wish i would have bought a better pan , Used to smallblocks and never had a problem with oil. Any advice would be appeciated..., Ed
