Ran my B/B chevy a little at the end of last year to get some shake down time on it, had a few issues, but the one that baffles me was loss of oil pressure on accell, like sucking the pan dry, let off throttle would return to 70-80, nail it, drop to almost nothing. Engine has a milodon long pan, w/2 trap doors and matching pickup, pump apears to be a melling high volume, pulled engine and have heads and pan off now, everything looks good, any ideas ? thanks Rob...
