If I had to do it again I would get TWM bodies instad if Jenveys as the Injector can be placed inboard or outboard on those T-bodies, also you won't need use any funky carb turn arounders or adapters as the TWM's will bold directly to any standard IDF manifold and the fuel rails wild be adjacent to the shroud. ( where you want them )
Linkage will also be less of a hassle.
IfI were you I would consider the current MS brain over the seqential, as you won't have to deal with things like a cam position sensor, and the gains of Batch fire Vs. Seqential are so minimal that I doubt you would ever see any difference.
