Dual TBI units

[Frederic Breitwieser]

Tunnel ram is even more interesting.

Why not drill and weld on individual injector bungs, insert TPI injectors,
and pretend its a chevy 350 TPI engine?  Put those nice edelbrock carb-like
throttle bodies on top, dual air cleaners, and you have a nice precisely
metered TPI system with the nostolga of the dual-carb setup, with a "dry"
manifold.

I was thinking tunnel ram, but what you
said makes sense. wonder what size the
injectors are in a 2.5l chevy throttle
body?
