1996 Cobra with a 5.4 DOHC on the dyno second pull

[@kevinpazos9846]

I know this is an old video, but by any chance what did the car eventually make. Im reading that the machine shop made an error in putting the engine together? Im just wondering because a 12:1 compression 5.4 4v motor with ported heads is a seriously badass motor that should be making well over 400whp. Im just wondering a bit more with the build, was it navigator heads or c heads? And by ported was it ported by a machine shop (3 angle valve job, cnc porting) or hand ported? Not trying to offend at all, you've done much more than I have at the current moment with your car. Im just trying to do something similar and I thought I'd ask the people who have done this sort of swap before.

Wondering the same, this seems way down on power

What was the cylinder clearance you set for the probe pistons? Because I've read that the 4032 alloy expands more than they are supposed to.

Bobby Kogel it has been so long I cannot remember. the motor is back out to rebuild (machine shop put the rods and crank in too tight) so I'll have that answer in a month or so.
