Newbie here. I'm building a 406 4 bolt sb to put into a 633 BMW. I need FI for Colo emissions. I've looked at Edelbrock, Holly, Fast, etc and have no real clue about how well they work. The car will be mainly a driver but I do want it to scream when asked. Pistons are flat top, plan to use a mild roller cam. I have ported camel hump heads but will prob go to Edelbrock Pf RPM. T-5 tranny, not sure of rear gears but guess about 3.5. Anyway, I would appreciate any comments on aftermarket FI systems. If this has been discussed before, an old thread would be nice too.

Seems like no one is interested to post in this thread. :D
Not sure with BMW but I was able to get quality Mercedes aftermarket parts (http://www.mbpartswarehouse.com/mercedes_aftermarketparts.html) with my old car. Hope you figured it out. Goodluck! ;)
