The average 408...

yah those dart pro cylinder heads are pretty nice pieces. flow way better OOTB the eddie rpm's. Chevy 383 are a **** motor to begin with, so it dosn't surprise me that those HP & TORQUE #'s are so low. the FORD 408 surprised me though. i'd thought it would give the eddie rpm headed MoPar 408 a run for its money.. apparently not. guess the compression made a bit of a difference.makes you wonder IF those motors were actually put on a dyno, or the justed used a dyno sim program.
