Alrite Im reading this book and I would like to know if anybody actually does this anymore cause it is a old book.
On the blockside of the mains you tap a 2 angled small ports on each sid of the MAIN main oiling hole on each mains. Its supposed to spray on the side of the rod and when its going around to cool the skirt of the piston for Nitrous apps. But spinning lets say 6900 would you want this?
Also Smoothing /Porting out the casting for the return by the back of the lifter valley under the intake.
Does anybody shim there oil pump actually? I usually smooth out the rear main oiling hole on assembly but just wondering if anybody actually shims the pump.
Has anybody ever did this? I got a 307 sonic checked to a 350 standard bore but would like to try it out if its worth it.
PRIMARILY anybody ever do the main mod like that?
Thanx- Mike
