Hi Guys; I have a 66 with a 350, roller rockers, tall valve covers. Dual master cylinder and front disk with rear drums. Looking with a tape measure it seems a 9" booster will fit. I was wondering which year, & model vehicel break booster would be a bolt on for this application. Also am I wrong about a 9" for easy removel of the valve cover as well for when I install the big block. Any past expertise would be appreciated.

I have a 454 with tall valve covers and had to change booster in order to have clearance. I used an 8" from Tuff Stuff Perfomance accessories they have the brackets also that made it an easy bolt up. Judgeing from my 67 I would say a 9" booster would have plenty of clearance.

MR. MERLIN; Thanks for the info. I though I was on the right track. Just making sure I didnt go into the wall with that question. Had seen it up here before without any real insite.:beers:
