Was the 6.0 engine you installed available from the factory in the '04 Silverado? If not, the truck will not be eligible for Stock. Not sure what all replacement parts are allowed (LS-2 pistons, etc don't sound legal). The camshaft would have to meet factory lift specs (or .430 lift, whichever is bigger). 4 links are not allowed in Stock It doesn't sound like your truck would be eligible for any Stock or Super Stock classes. Probably would have to run in Pro in brackets, or maybe Hot Rod if it can run 10.90 1/4 mile (7.00 1/8 mile) and has all the safety requirements. Your best bet at an IHRA Divisional race right now would be to run No Box or Street ET.

Here is the link that I found for the rule book.

The camshaft would have to meet factory lift specs (or .430 lift, whichever is bigger). I'll have to go back to the stock cam (could I run a factory cam from other years?)
4 links are not allowed in Stock It doesn't sound like your truck would be eligible for any Stock or Super Stock classes. 4-Link is out then
Probably would have to run in Pro in brackets, or maybe Hot Rod if it can run 10.90 1/4 mile (7.00 1/8 mile) and has all the safety requirements. 10.9... thats a no (I wish)

Could I compete in those classes, or would I be an anchor and waste time to other drivers in the class? I just want to fit in a class that would welcome my ride.

"Camshaft must retain stock lift for horsepower claimed, per IHRA Tech Bulletins". You can use aftermarket cams (Crane, Comp Cams, etc), as long as the factory lift is met, but not exceeded. Any duration is permitted (I believe). Stock Trucks "maximum lift limited .430 or OEM, whichever is greater".

If you run Pro, Street, No-Box, it's just a dial-in bracket race, so yeah, you can run just about anything. Even slower street cars. My first street car that I bracket raced was an eighteen second Olds Cutlass. Some basic safety items will be checked (battery is secure, minimum of a one pint overflow tank, etc).
