good evening,
I currently have Don Hampton building my 8-71 blower for what will be a 521 blown boss motor in the next 6 months or so. I will be running a set of your boss 9 heads on a DOVE-A block in a 66' GTA Fairlane. The car will be mostly street driven with a few weekend race track runs. Car will weight about 3800 with me in it. I am running a fully rollerized mighty might 2 C4 in it that has 2.82 gear set and custom 10" torque converter to stall at 3500 on foot brake and 4500 on t-brake. Rear end gear of 4.10 with 33x21.5x15 tires on the back. My question is with these heads being as good as they at breathing do you recommend running something like (2) 850 quick fuel carbs on an application like this? Also is there any type of part # on the DUI you run on your blown boss?
Ya that is what i was affraid of. I have a fellow member willing to give me a mallory unit and i would just need to get a crab cap, if that don't work i found someone that makes offset ones in either 3.2 or 7.2" offset using msd cap.
I have a similar problem. I'm working on a 49 Merc that will have a blown boss 429. My BDS manifold is only 5 1/8" tall, which is too low to get any distributor that I know of under the blower. I don't think even a crab cap would solve my problem. I'm really interested in some info on that offset distributor that you speak of. I am at a dead end! Would appreciate any advise or recommendations from anyone.

A friend of mine just had a shortie distributor made for him by Littlefield to go along with the 10-71 he purchased from them, right about $300, MSD internals. Might want to give them a call.

Your best option is to turn the intake around, That should help. With the pop off plate in the front I dont think you can even slide in a dizzy with the blower off the manifold.
And heres a couple nice offset units if thats what you want.
Wow this was revived out of no where. I actually e-mailed Swartz racing in regards to their offset ones. He had told me being a street set up with the blower he recommended the 7.2" offset with the MSD “Pro Billet” style head – includes a Hall-effect pick-up and mechanical advance mechanism that can be tuned or locked out. It was roughly $700 for that setup.
Side note on the carbs for the boss setup the answer i received was (2) holley 850 blower carbs.
Thanks for all the help and advise. At the Medford car show last weekend, I did see an FE with a 2" spacer on the manifold, but I'm trying to keep this blower as low as possible. Also, I believe the BDS manifold for FE's is taller than the Boss 429. So that 7.2" offset looks like the way to go! Thanks again.
Does anyone have any tricks for holding the NASCAR rod bolt while tightening the nut? Also is there a torque spec that can be used instead of the bolt stretch method?
Thanks, but enough with that Rated PG terminology. I prefer the term, "cat's asss," from which I believe your term is derived.
Thus far, the mag drives are proven to 242 mph. Currently working on two engines in-house that will each run them, one of which we hope will produce more power yet.
