Adjustable Hydraulic Valvetrain |
By S. W. Eissele - 12/17/2001 11:58:31 PM; IP 208.130.12.180 |
I am building a 428 SCJ with Edelbrock Performer heads and intake. I am using Lunati camshaft #00053 with .514/.514 lift, 223 duration @ .050. Using stock Ford 1.76 adjustable rockers with aftermarket pushrods that measured 9.250 end to end. The adjustment screws were almost all the way down to get proper lifter preload. I then tried a set of stock Ford pushrods at 9.350 length, with very nearly the same result. I would have to go almost .200 longer to get the adjusting screw anywhere near the center of it's travel. I've been told this combo usually requires shorter pushrods if anything. Any ideas out there? |
