have you looked at the physical dimensions of a 4.6L cobra motor dohc , and a 5.7L LS1 ? the pushrods allow the cylinder heads to be MUCH, MUCH smaller. a phsyiscally smaller engine that can sit very low and very far back and be easier to work on.
just my .02. each one has its goods and bads. moving to general car chat.
DOHC doesn't have pusrods. Cams sit on top of the head.
Name one pushrod engine modified or not that can rev higher than 9k one thats all I need.
As far as cost I can get you M5 drivetrain complete for $4000. Tranny is good for over 1000hp from factory as well as the differential. so only thing you need is clutch which I can get you for $700. Turbo setup probably around 4-5 g's drop this into 2002i and you'll be dropping 7s. times.
How much will it cost to build 7s. mustang?
