How would,say a rcsb 5.3{stock}, compare to say one of the lt1 z28's {stock} . like 0-60 times and 1/4 mile times.

 

well one time in my truck i raced one and kept up with him pretty well on the street, at that time all i had was exaust. but that car was horribly maintenanced and the driver prolly wasn't the best either.

but i'd say stock to stock the 5.3 would prolly have a good bit of ground to gain.

 

A stock LT1 Z28 should be capable of 14.2-14.6 ... assuming it had the miles to go along with the year and its was an auto. A 6 speed and a well kept vehicle could knock a little harder on the 13 sec barrier if properly driven.
