I have been in a discussion here, and i think i need a dose of reality at this point.
the problem is, i have begun to doubt my beloved Hemi.
what we are talking about conserns N/A applications only (well maybe nitro, but thats a different story, well maybe not)
lets say we are most concerned with 5000-7500rpm what do you guys think would be better?
here are some of my points.
1) i think its easier to make more compression in a wedge style head than a hemi.
2) cams....try to go crazy with the lift on a hemi and you end up slaming the valves into each other.
3) i'm thinking that smaller ports, and smaller valves, shrouding wouldn't come into play much. 4.375 bore. and it might acually flow better in this rpm range. 2.45 x 1.94 valves vs. 2.30 x 1.88.
4) smaller combustion chambers might be better for use with a slow burning fuel. you could even cut a grove in the quench area and angle it toward the spark plug(s) if dome type pistons are used.
at what rpm would a hemi pull away from a wedge? opinions please.....
thanks
