Which roller timing chain?

Im looking at the Comp Cams 3136 and the 2136. The 3136 says its a racing chain, and the 2136 is a street chain?

2136
Vendor: Competition Cams, Inc.
Product Line: Competition Cams Timing Chain Sets

Finish: Machined

Chevrolet: 1987-92 4.3L/5.0L/5.7L, Magnum Double Roller timing set

This Magnum series timing chain set is designed for your high performance street machine. Features like a pre-stretched large pin, double roller chain, thorough heat treat, and dynamic balance assure you're getting one of the best double roller designs on the market.

Sold individually.
3136
Vendor: Competition Cams, Inc.
Product Line: Competition Cams Timing Chain Sets
Material: Billet Steel
Finish: Machined

Timing chain sets for every need.

Chevrolet: 1987-90 5.0L/5.7L, with factory roller cam, Hi-Tech Roller Race, timing set

Comp Cams offers a complete line of timing chain sets, including this Hi Tech Roller Race timing set for extreme racing. It features a double roller chain, a triple index gear, oversized rollers, and a dynamic balance.

Sold individually.
Now, the "race" one is cheaper, but is there a major difference that Im not seeing? They are both for roller cams. Which should I go with?

Instead of guessing, call them about it.

Why use the phone book when you can call directory assistance?

Yo Al,

The one for race is made of billet steel. The street one is cast iron. I would go for the billet. The timing set I use is from an Aussie company, can't remember name. Its really nice. Billet upper gear with torrington bearing on the back side for smooth operation. Heat treated lower gear with 8 different keyways for cam timing changes. Not very practical for everyday tuning, but nice feature!! True roller chain of course. The best part is I got it from my local speed shop for $20 more than the top of the line Cloyes. No dis to Cloyes, they make a nice part too...
