Nope.
i have a problem, picking the right pump.. no after a mail to manchini racing, Huges engines and a chat with the summit live tech support. Everyone found that if u haven't blueprinted the oil system and have std clearances, u should always use the HV pump. the reason is that it only gives 20 to 25% more oil than stock. this will help maintain oil pressure on low idle (witch is good for a street engine that runs a lot on idle) the How to big inch sb mopar, Build High Performance Chrysler Engines and How to Hot Rod Small-Block Mopar Engines say the same thing.. i have all boock so i checked it up..
I picked the HV melling pump, milodon pickup and deep pan. i also made the modifications to the block that Moper mentioned... so lets just wait and c where it goes. I will report results.
