TODAY is a Great Day to visit our Store and order the parts you need for your truck!
big valves in the heads and polished etc.
I am thinking I would want at least 700 cfm not sure what this is.
what would be a good intake for this carb? Single plane, dual plane, raised runners or stock?bear in mind the other mods and I want to keep the powerband pretty wide as I will be using the sm465.
High rise dual planes have a straighter shot to the intake runners and a larger plenum volume under the carb. This means they breathe better, but because of the larger plenum volume, they give up some low speed velocity. On an engine with those heads, and a mild street cam it would cost you some low end torque, and maybe give a little more top end, when compared to a low rise dual plane.
wouldn't the fact that it is a dual plane intake kind balance out the higher plenum volume?
However that was not a q-jet on a high rise, kind of wondering if the q-jet would work as well.
btw what would be a good set of headers to get for this truck, I want something that won't rust right away and is budget friendly.
