Milodon pump, pickup and pan. Soft touch chipped at 6800.
It's really a race for the weakest part.[trying to keep up with all the better parts]
Weakest link etc.......
I won't push it over 6500 and will most likely be shifting at 6200.
I will be using stock 452 ported cylinder heads.
It cost so much more money to get to that next level with any amount of durability.
Trying to make the torque as high in the band as possible so that the horse power is higher.
Everything has limits and keeping the engine in the range of the weakest link makes the weakest link sometimes ----not so weak.
Thanks again for the replies :drinkers: here's to ya
moper....
If you grove the #4 journal of the cam so you have full time oiling then you have to install oil restrictors in the oil passages in the block.
In my max performance mopar big block book, it was suggesting to use spray bars as a means for additional oiling and also as a means of cooling the valve springs.
I guess it only takes about 5 pounds of oil pressure off your total oil pressure.
Andy finkbeiner also states in his book that when you grove the #4 cam journal you give even less oil to the #4 crank journal.
He has seen an engine with this set up spin the number 6 and 7 rod bearings in a dyno test, even though the back of the engine where the pressure was being measured showed a constant 70 pounds of oil pressure.
The more power we make the more problems rise up with stock blocks.
Most aftermarket blocks have addressed all these problems and are made with all the fixes already in the casting.
Ps Hemidenny..... I am building a 400 big block.
