440 power gains/ aluminum head advantages?

In your mind, have you skipped ahead to what you’ll check next…….if the cam timing isn’t way off?

While the loose chain isn’t at all optimal…….that by itself isn’t the cause of the missing 1+ second ET.

The solid lifter……:thumbsup:

if the timing chain/cam isn't way out of degree i'm next to assume the cam/lifters ate eachother so i'll inspect every cam lobe and lifter face. if everything is good there im not sure what i could check. i'll probably buy a fuel pressure gauge to install and watch and check running temps of the trans to see if ive got converter/transmission issues.
