You can also use LS6 springs. Like $56 a set and work just as well as the 915's.

Yes Also you need Comp Cam retainers PN 787-16, $50 from Summit, and valve stem seals you can pick up at a local parts store for under $2 each, either cross Sealed Power PN ST2015 or look them up for a Dodge Daytona 4cyl Turbo.
Also to same some money on shipping across the ocean you might try a GM dealer over there. GM PN: 12499224 set of 16, same EXACT thing summit sells.

I just bought some springs part#vs 574 from Bullet racing cams.I paid 70 bucks shipped.They have more seat press than those.Also work with stock retainers,seats and keepers.I like that 503 cam.I have it in my LT1 engine but its not running yet.
Im about to install the Hot Cam in my 383 vortec tbi.It should be running in a couple of weeks.What intake are you running.What ecm.Who's doing the tunning?
at this time im runing edelbrock performer rpm , but in about few month I will install http://www.summitracing.com/parts/EDL-2913/ and one of those cams. ECM is 6965 from 9C1 caprice . im doing tuning myself i upgrade ecm for AT29LV256 microchip , use WinALDL and tuner pro . i think im doing it well so editing the program is not a problem.
