I will be honest. There are two 408s being built and this is going on the lesser of the two (maybe 500hp). Running the single 4-bbl M1 with the Indybrocks would probably be the better choice but I have had this setup for way too long and it needs to be utilized. I guess the cool factor is playing a big part in this decision.
If for some reason, it has major issues, it will come off (but those issues would have to be pretty damn big for me to pull it off). I have talked to two other people running this setup on their strokers and they are having pretty good luck with it. There are some internals mods (mainly the addition of dams) that need to be made before it run. I will update when there are new developments. BTW: There is a good chance I will just break in the 408 with the M1 and then switch over to the STR12 after everything is dialed-in.
