That's a smokin' deal if it is current. That's what the dealer pays for them today.

I also went with GM lifters I am happy with them I never rev the motor past 5500 Max.

I also using a GM LT4 hotcam no issues with the slandered length push rods (Comp Cams harden Push rods $30.00 for a set of 16).

But I do have some valve train noise but I reading it could be my Comp Cams Ultra Magnum Full Roller Rocker Arms.

Yeah Superior has them for $121, but I am right down the road from Summit so I dont pay shipping.

Here's a little more detail of the difference between the LT1/4 and LS7 lifter. The working length of the LS7 is about .040" longer. So that means your lifter is pushed down about 1 more turn at the rocker stud.

Background:
I had just bought .050 longer pushrods to accomodate my .050 under base circle cam because couldn't get all the lash out at all the rockers with the stock pushrods.

I decided to change out the lifters and found that I needed to turn the rocker nuts down 2 turns. Too much. Put the stock pushrods back in and back to just one turn.

So, now I have a brand new set of 7.250 length .080 wall pushrods for sale.
