Im planing on performing most of Guitar Jones's mods to my big-ish hydraulic camed 318. powerband ends at 6500rpm so thats all i plan on spinning it. 2 main questions: 1. I cant find oil pickups with advertised 5/8" ID pickup, is this a custom setup? Is this size even neccessary? or does someone have a part# for one? I havent deciced on a aftermarket center sump oil pan, but theres not much info advertised on the matching pickup tube for them. 2. ive purchased 12" long 5/16" & 1/2" drill bits from Fastenal for drilling the block, but the only option for this length was the standard black oxide finish bits (not ideal for cutting metal). I was curious to those of you who've done this mod what bits did you use? The bare 318 block is on the engine stand, back from the machine shop, and almost ready to start assembly. I appreciate any help.
