Any one try this ( Mopar 318 Engine - Cheap As Dirt )

If you have a 318, then you have to buy the core 360 heads, right? I dunno... There's no difference in cost for me between doing a 360 vs 318 vs 440. Maybe a couple hundred because of the RB parts costs, but the small blocks are the same. So yeah - you've proven a "larger" cam 318 with bigger heads can make 400hp with good static compression on a dyno well known for "happy" results.
I'd expect a 360, with the same machining, type of flat top piston, the same camshaft, the same intake, the same everything - would add another 30-40 pound feet of torque off from idle up, and probably another 15-25hp at peak for the same money. If torque on the street is king, how can a torque peak of 4800 be good? It makes less than 25% more torque than a stock 5.2L Magnum & less than 15% more than a bone stock 5.9L Magnum - and it makes it 1200 rpm higher in the rpm range.
The best info in that article was the bit about the hydraulic lifter/valvetrain control issues.
