| Lets see 1. The visual aesthetics of it :-) 2. Perfect alignment of the injectors to the lower plenum 3. Differences between lower and upper plenum heights. 4. Having to modify the lower plenum for the injector O-rings, and these are what metal? Is there anything isolating the injectors from the heat transferred from the lower plenum? My lower plenum is port matched, blue printed, and extruded hone. it was done a step process so everything was properly fitted. I would hate to have something happen to my lower plenum. 5. Modified Balanced tube, in my case I have to have it re-chromed :-) more down time. 6. Throttle body bracket has to be modded. 7. with all the work you did you should have made the rails have dual return so they could feed the rear cylinders first which run the hottest. So those are my concerns but in a drag car and etc I would probably be using along with Methanol and 50 PSI of boost :-) Don't get me wrong I like your product just not 100% solid on it.
