W2 2 barrel intake
If you can find an '89 - '91 318 TBI intake manifold, you can redrill the stagard bolt pattern to the large mopar 2 barrel pattern.
It's basically a mid-rise good flowing factory 2 barrel manifold.
See if that will fit in with your racing rules.
'89 TBI Intake ^ nice big plenum on these.

Here is the pattern I use for redrilling and tapping to go to the large mopar 2 barrel pattern.
