pushrod length I got my ls6 cam in for my 4.8 truck motor. What size pushrods has everybody put in your truck swaps? Its my dd and I can't afford to have my truck down for the time it would take to put the cam in then measure the length then order the pushrods and wait for them to ship. I'd like to hopefully do this all at once.

If you're using stock or LS7 lifters, the pushrod length can be off a bit and you'd be okay. They are more forgiving. However, still measure and replace the stock pushrods with the correct length, hardened pushrod.
The ls6 cam has a smaller base circle and if you didn't change your heads at all and did just a cam swap then you are just going to lose some lifter preload..
I personally would wait that way you don't have to redo taking the valve covers off and rockers and the whole shabang!

10 Camaros You Should Never Buy
I know its more work but I can't afford it being down more than a weekend. The good thing is getting back down to the valve covers is relatively easier and less time consuming than the whole swap itself so I'm not so concerned with that part. I'm main concern is that after I get the cam in and measured the pushrods, that the stock pushrods will hold up for 3-4 days I'll be waiting for the new pushrods to come in
Back on the olden days, when the LS1 first came out, a few engine builders were re-using stock pushrods with cam installs. I would personally upgrade to Manton 11/32 pushrods after measuring and run the stock pushrods until they arrive. Just keep your foot out of it until the pushrod swap is made.
The pushrods in ur 4.8 are the same as the pushrods in the ls6. They compensated by have different length valves. I have ran my 5.3 with stock pushrods and the 04 ls6 cam for 170k miles. Lifter preload took care of it and i havent had any issues. Just throwin thAt out there

they measure in "overall" length vs typical "gauge" length like most pushrods come in.
so if you have a typical comp cams pushrod checker $20 and measure the "gauge" length with it, you can add .015 and get the "overall" length.
then order them

I asked Hinson how they define the length of the pushrods they have listed. Whether it's actual length, or if they calculated gauge length. They never got back to me. So I ordered them from Tony Mamo.
You can always order over the phone with manton with a Credit card.
