Fast,

Thank you for the Hy-Lift part number! I emailed them as soon as I read your response.

Per Hy-Lift Johnson Sales: The B-2330S is no way comparable to Comps lifters. This is the best lifter made for the 340. These lifters can achieve 7000rpms, seat pressure up to 160lbs & open pressure to 450lbs. Pre-load is .030" and the seat height is close to the other brands. He said that this lifter is very popular with you High End Mopar Builders. $224 a set of 16.

If my existing Comps don't workout, then it looks like I have found my next hydraulic lifter!

Thank you for giving me the part number for this lifter!!
