I am by no means an expert on anything. Yes I copied my engine out of the back of a book. The section on manifolds said that The M1 tested out the best in that application, I got alot of advice on the carb and went with a 1050 (8082) I am happy with the results, could use a touch more gear but the 4spd helps alot. I am gonna get some track time in this summer I just have alot going on right now and it's not a priority. An with what I spent fixing my Truck the last few months I could have bought a trailer and a years supply of tires and fuel. I do take the car out for a drive in the country once in a while. and it all fits under my stock charger hood.
