Hi, The KMJ pan looks good.Price is right.Is this motor going in a street car?what are your HP,TQ estimates, I've away's felt that the oiling systems on our big blocks is good but could use a little help on a hp build.Increase the pickup size.
As per the Mopar bible on hi performance builds, the norm is to inlarge the pickup tube threads from 3/8" to 1/2" NPT HEMI pickup size.
some guys use a hand drill, the problem with this is with a drill is that the new threads are real close the edge of the casting,and you run the chance of it cracking the block when tapping new threads.To do this correctly it should be offset drilled in a with an endmill in a Bridgeport machine then tapped.
Solution, plug the 3/8" pickup boss and run a Milodon #21001 setup pictured below.This dose two things, 1, you don't have to increase thread size and take the chance of cracking the block 2-the oil pump is sucking oil threw a AN-12 (3/4") low restriction hose. this is one area that over kill is not a bad thing.on a stock motor necessary? no but on a hp build I say yes if this is a mild build that pan while be fine but have the pickup size increased by the machine shop.
I assume your going to run a windage tray, 4.15 stroker cranks require a different tray than stock. Dose KMJ sell a stroker tray for that pan? I've always use Milodon . never had any issues with there pans or parts nice heavy rails.jig welded I use on my 493, the 30931 low profile pan.
I would recommend a skid plate. pan will hand down past the k-frame a little. Mancini racing sells them. I'm shore others will say stock pickup is fine maybe but why take a chance on your investment.just my thoughts. good luck.
#21001
STOCK COVER SINGLE LINE SYSTEM
A simplified system that is great where space is tight. Using a stock oil pump cover allows this system to be more compact with no need for a separate oil filter adapter. Will supply adequate oil supply up to 7000 RPM when used with Melling M63-HV high volume pump. Use with Milodon #30931 low profile or #31015 deep sump style oil pans. Works for both Wedge and Hemi engines and all motor mount
