Pushrods help
Changing the cam out n a 95 bird and I'm running the Comp 26918 valve springs and the LS7 lifters. I hear with the LS7 lifter I will need to run a longer pushrod? Can someone steer me in the right direction of what pushrods to run?

Measure, then order.
Depending on the head gaskets, milling, etc .... probably 7.150" or 7.100" since the LS7s have a shallower cup.

Depending on the head gaskets, milling, etc .... probably 7.250" or 7.300" since the LS7s have a deeper cup.

The only true way to know is to buy the Comp Cams 7702-1 length checking tool and measure using that. I thought the LS7 lifters have a shorter cup atleast mine appeared to?? If the block hasn't been decked, stock head gaskets, no milling to the heads, same base circle cam, your looking at a 7.150-7.25".
Every other thread I read confirmed that they are in deep shallower.
So the pushrod should be shorter than stock.
As mentioned above ... measure.
