thanks for the info davebat i appreciate all the help i can get on this subject,i have never built a large cubic inch sbc before
also will the block need any clearancing for that 3.875 stroke crank? also what would be the most cost affective crank to go with i would at least like to get a good name brand i can trust like eagle, any ideas what i would be looking to pay for a good 3.875 crank for the 400
thanks for the help
