Remount air block to fit.
Note that the stock mounting of the air tube will obstruct the subframe connector and thus was relocated from the top of the exhaust tube to the side.

Installation Notes:

Starter: I used a geared hi-torque Corvette unit. GM part # 10455702
The drive gear from the H.O. distributer was transferred to the original LG4/LG69 distributor. The H.O. drive gear is compatible with the H.O. steel roller tappet camshaft (1987 introduced the new harder cam and distributor gear).
The GM H.O. 350 conversion is certified to meet emission requirements without an EGR valve or carburetor heat stove. Thus the EGR block off plate should remain.

Installed ZZ3 (Dusty and in need of a cleaning)
