Re: [Chrysler300] 331 Hemi upgrade

["Laurence G. Johnson" <laurence_g_johnson@xxxx>]

Hi Zak,
The basic horsepower enhancers are more cubic inches, more air flow, and 
more compression. The old hemi motors respond well to all. More inches are 
most easily obtained by over boring. This will have the added benefit of 
raising the compression at the same time. Since you are buying pistons 
anyway, a little bigger dome will also raise the compression but don't go 
crazy here, you need to live with today's fuel.Stay at 9.5:1 max. Check to 
see if your block is drilled through the lifter bores and can use hydraulic 
lifters. If so, you might want to think about getting a set of current 
hydraulic roller lifters and use a short duration high lift street roller 
cam. This will really boost the breathing capability while maintaining 
drivability. There are several good aluminum intake manifolds available from 
most manifold manufacturers, Edelbrock, Weiand, etc. Top it off with a 
650-750 carb and a big exhaust system and your ready to take on most 
anything.
