83 z
i have a 83 z-28 with vin "h" engine code but my z has all the ho badging and air cleaner i was wondering what the hp rating is for this option. because everything shows for the vin "h" without ho can you help how many where made this way
The HO was vin G... If you have H you have a low output 305 rated at 140hp. The L69 (vin G) was rated at 190hp. It had at the least, the HO aircleaner, 3:73 gears, higher flow cat and exhaust, and a specifically tuned quadra jet.

I have a 83 HO Z28 which I am quite sure is the HO... it has VIN engine code 7. H is the code for the LG4. The G code was used for the L69 starting in 84.
It sounds to me like somebody found a HO car in the junkyard and robbed all the little pieces off of it and stuck them on a plain-Jane Z28.
OBTW - all 83 HO cars (mine included) are 5-speed. If yours is an auto, then it's another absolute certainty that it's not an HO car.
Also, absolutely none were made in 83 or any other year with the body trim for the HO but no HO motor. That would be kind of bogus at best, like people who put SS emblems on old Malibus with drum brakes and the Malibu trim still on the rocker panels. The factory doesn't do stuff like that.
