440 power gains/ aluminum head advantages?

The cam being 5* retarded isn’t doing your combo any favors, but it’s not like that alone would explain the huge power loss you’re seeing.

Correct it to 104-105 c/l, button it back up and see what it’s like.
got it all back together yesterday at 105.5 icl. it definitely has better cold starts and a night and day difference with throttle response. i haven't got coolant in it yet so i haven't taken it down the road but i hope ill feel a little difference. but also the new 440 source chain was much tighter. almost no slack compared to the new comp chain and gears with 1/2 in deflection. even if the degreeing didn't make a difference it was worth it to me for the peace of mind and the tighter chain!! im also installing a fbo ignition box and flamethrower coil after i take it for a drive. i've been wanting an upgrade from the cheap auto parts store ignition box and coil replacement. hoping to get it to the track within the month to see how it does. thank you for all the help and advice and i'll be excited to share with you my time slips to see a difference
