I used the search function because I remember this post some time ago. Anyways how much was a professional cam install
spring, cam, pushrods, no tune.

Is $500.00 too much.

 

$300-$500 is an acceptable range. Shops that do them a lot can charge a bit less because they know all the tricks. I think MTI sometimes does them for $350 because they've got it down to a science. My local shop would probably charge $600'ish because they don't work on a lot of LS1's.

 

or ask for help from someone in your area and give them a few bux watch and learn
