the 284-484 wont make enough vacuum for power brakes. Its 248* @.050" and ground on a tight 108 lsa.



Agree... much over 230 to 235@ .050 in a 340, especially with tight LSA, isn't going to make enough vacuum for PB.

One member mentioned a lower duration purple shaft that would likley work, there are other options. What are your goals?



My goal is to have a street friendly 340, that has enough power to be fun. Also I want to keep my power brakes and get the 904 rebuilt with a shift kit. I was thinking something like the transco TF6 Automatic shift kit.
This is my first restore, and I'm trying to keep costs down and use what I have. The car came with a 318, but the cost to rebuild it are about the same as buying a rebuilt 340, so I might as well get the engine I always wanted.
