Chilton, Motors, or Haynes manual should give a detailed description.
As far as I know, all small blocks have adjustable valves. Definitely all small blocks built before the LT1 and LS1.
with the car running, back off each valve till it just starts to tick, then tighted till it stops, the 1/4 turn more. this will set the valves at the mid stroke. it will run perfect then.
There was no LT1 in the 1992 B body, the LT1 was introduced in the F body and Corvette in 1993, and 1994 in the B and D bodies.
There was no Camaro LT1 "SS" in 1995, but the stock LT1 (assuming you were referring to horsepower) had 275 hp.
possible bent, warped, or torched valve - bad valve seat - or worn valve guide
lt1 is a 350
The LT1 Trans am is rated to have 275whp from the factory.
LT1
The 1994 LT1 makes 275HP, while the 1995 LT1 makes 285HP stock.
Is this a Factory LT1? In your 1992 Z28?
