Timing chain set for the street/driver?
I've had good luck out of the Edelbrock double roller chains. I replaced the fuel pump gasket on my 360 in the 71 Challenger, and checked the chain while the pump was out. Has about 10K miles on it since it went in in 95....still tight. Motor has the Mopar Performance 761 cam in it and gets the snot run out of it every time the key turns, so the chain has held up well. Iwis chains are very good also.
