R3D, question for ya.
Using the shortblock on the bottom of the page,
http://www.karkraft.com/short_blocks.htm , what kind of compression do you estimate the motor would run w/ ported heads, agressive street cams, 5.4 HPS intake and longtubes and what #'s would you estimate?
If the link doesn't work, its a new 5.4 4v shortblock w/ flat top pistons and a steel 8 bolt crank.
