Thought I'd put up some pics and descriptions of a real nice little 351W build I did for a pre-runner truck.
Stock block and crank, Eagle I beam rods, Probe dished pistons, Dart Pro1 170cc heads with a little clean up, Comp solid flat w/1.72 Scorpion rockers, Edelbrock RPM Airgap and a Holley 750 set up by John @ C&J Carbs.
First thing to do was some oil mods to the block: This was installing a restrictor for the lifter galleys at the rear of the block...a little tricky.
It had to be drilled and tapped down inside:
You can see the restrictor had to go between the two oil galleys...the main galley below, and the lifter galley(s) above. Oil flows in the direction of arrow.
Little blending in the crossover for the lifter galleys:
Front main oil passage is a lot larger than the rest, so it gets reduced to balance out the pressure to the mains:
Rest of the block gets restrictors to the four rear cam bearings. (front cam bearing doesn't get resstricted because the passage also supplies oil to the dist. gear):
