Thread: Big block oil pump in a Small block

Tweet

Not to sound controversial - but why are you doing this? There's some mighty fine high capacity small block pumps that are a direct bolt in without any messing around..

You are right. But a big block melling pump is 39 bucks. Circle track guys have been doing this for years. It will give me the extra oil I want for my flat tappet solid lifter cam at idle.

I did this years ago with a but can't remember what pickup I used for the stock pan. That was the sweetest running small block engine I ever built back then that seen 8000 RPM'S (and more with a missed shift) daily and never came apart.
