[DeTomaso] NPC: DOHC or Pushrod holy war.....Was: New Corvette Engine

[Dave Londry]

Now if you said:
"There is no reason to build a DOHC engine instead of a SOHC engine"
  - I could get that. Twin cams are just more shit to keep spinning and 
the width is ugly,
     So long as you manage to place big valves, across a hemi chamber, a 
single cam is fine.

But a pushrod with in-line valves - that's just still more heavy shit to 
keep moving and to no benefit.

Now the direct injection system in the new LS is very fine - keep that part.
