Default pushrod length?

Ok I think I understand the process for checking pushrod length. I used the EO/IC method with a jegs pushrod checker. I checked 2 exhaust and 2 intake just to be sure my measurements were the same. When I checked the length I got 7.430. Then I added .062 preload which gave me 7.492 so I assume that a 7.5 pushrod would be acceptable. Is this a normal length? It seems long to me. Its a lq4 with unknown mileage (looks like its never been apart), upgraded trunion rockers, and a tick SNS torqueMAX Stage 2 227/235 .61x"/.62x" LSA110+3

If it's stock than pushrod length is 7.4 inches. Read this: http://www.ls1.com/forums/f7/how-mea...length-172530/

Those do seem a bit long although I am not familiar with the lq4 (never had one apart). I am running 7.475" pushrods but I also have 0.125" shims under the rockers.

I bought 7.4 pushrods and when I put them in there is .030 play according to a dial indicator with the rocker torques to specs

You've got to go with what the motor calls for. When I measured mine, they were extremely short I thought, even called texas speed and they told me that they were short. After walking through the process with me, they said it sounded off but was obviously what was needed.

If your confident that you did it right, be confident in ordering the pushrods.
