I was told that I have a 1 1/2" spacer between my edelbrock carb and the manifold. I was also told that if i remove it i would gain more horsepower. It was put in place to give it a higher top end speed. Is this true and if so how do i remove it. Also I have a 10 bolt 8.2 rear with a 2.82 gear. I would like to run a 12 bolt 411 gear. I am running a th350 tranny. Will the 12 bolt hook up directly to the th350 or do i have to go to a th400 tranny. All in all i am looking for more out of the hole power as I do not see myself ever taking her to top end. No place to do it anymore around where I live.
