401hp...with the stock bottom end screaming away at 6,100rpm.
I know the following is obvious to most of you fellows, but for the newbies following this thread, it should be said:
The trick of that build wasn't the go-fast parts, it's a testament to how well built the 318 is (and the valve spring selection) that it didn't start chucking itself apart.
Further, it really doesn't hurt HRM to risk blowing up or wearing out an engine prematurely for a number - because the engine was built with the intent of providing a headline. Any other person on a budget build wouldn't have dared pushed the engine that far - and would have probably been quite content with pass #2 had he/she the cojones to do so.
Nevertheless, while I must admit that I enjoyed that build and the results as much as the next guy, I keep wondering what they did to the ignition timing on the stock carb. I spy an HEI coil on the board in the back, and some sort of ignition controller that I can't identify. Either way, they aren't factored into the build price. Also, doesn't mechanical advance control on a Mopar electronic distributor require an adapter plate?
One other thing - if someone is this desperate to get 400hp out of a 318, it'd make more sense to start with a Magnum 5.2. Roller cam hardware already part of the package, better heads, pistons may be slightly higher compression (don't recall, as I wound up building a 5.9 myself), better port flow, etc. Granted, it's not as much fun saying you squeezed 400hp out of a flat-tappet 318, but it's a hell of a better way to get there.
