Does the Dart BBC Aluminum Block require the .300 longer Roller Lifters and if so do the longer Lifters require shorter Push Rods or is the Push Rod seat deeper in the Lifter so you use standard Push Rods?
Thanks Bluenose

Yes, our BBC aluminum block does require a +.300" taller lifter.
The taller body usually just moves the link bar farther up the body and does not affect push rod length. However, pushrod length should always be measured to assure correct geometry.
