I've seen A LOT of posts about making HP with a 318-So why is it so ???

a clean short block is always nice. You saw what throwing a dirty rusty block together got our subject of the Tony and Nick show. But that vid actually had more info in it than gaffs: Look what you get when you scrape something together from a mishmash of parts and a hose. It pretty much highlighted everything that could go wrong short of reusing a head gasket that could go wrong with a quick build. Low oil pressure, leaking core plugs, wrong pushrods on a stock valvetrain when using a reduced base cam (pretty much all performance LA cams are reduced base to get the lift they need due to the cam bearing size and cam blanks). So watch and enjoy...better him than you. Nick didn't do anything wrong short of the oil pump suction gaff. He just chucked up a turd and dyno'd it. It wasnt up to him to diagnose the oil pressure issue and he found the preload issue too late to try and fix it but I doubt he could **** some longer pushrods or an adjustable valvetrain to throw on. Id still like to see a real 318 dyno'd at his shop: not a "built" but maybe a blueprint with manifolds and all. Then we could prove/disprove the 230 HP rating of the LA 318, Magnums not included.
