41 to47 psi
LT1
94 did come with it. LT1 started in the 93 Z28's it has a strong motor i have a 94 z28 and iv done replaced 3 transmissions
275
Is this a Factory LT1? In your 1992 Z28?
you dont! the computer controls the optispark completly...
i have a 94 z28 with a 150 mph speedo
yea it did chevy lt1 350 cubic inchs 275bhp
check cylinder compression. rings could be out.
it depends it could have either the 4 speed auto or 5 speed manual the z28 came with both options
check your vin, if the eighth digit/letter is "p" then the car came with the lt1 engine and therefore would be a z28
ummmm if i got this right there was only one Z28 and they both have the LT1 in them and have 285 hp
