The OP is running boost so this manifold will flow fine.
There is no pop off valve and the distributor clearance is problematic with Indy’s blower top….
A “Reverse Offset” 8-71blower will have the added 1” blower case to the front of the engine, aiding in distributor clearance…..
Indy does have a $900 offset distributor to accommodate for their shitty designed blower top.. lol

However,
@Coyote Jack modified his ModMan blower top by moving it forward to provide distributor clearance.
