I have decided to leave the Comp 503 in my Impala with the LE2 heads. I have a custom LE2 cam with the same duration but with a .6xx lift on 1.6 rockers and a 10x LSA for sale. 250.00 with shipping. Cam is still in the box with the cam card. E-mail me at hvyss@hotmail.com for full specs on cam. Going to try to put a 4400 lb pig in the 11's N/A on a ity bity Comp 503.
