Ideas for intake manifold and larger fuel injector for engine build

[run96k3500]

I need some ideas for the best intake manifold so that I can get the most air into the truck. No I do not what to super charge or turbo. N/A only. Also what are some good fuel injectors that are better than stock and have more flow than the Bosch injectors.

I think it all depends what you want to do.

If you want something that makes a ton of top end just get a good carb manifold and have injector bungs welded into it.

There are a couple of other manifolds out there that are simmilar design to the stock vortec, and there is the ram jet intake.

Or you could just do some serious porting on the stock intake.

Are you still running the stock cam and heads? If so, the intake is not holding you back. I checked map values on my truck that has basic mods, at 5,200 rpm there is no vacuum present in the intake.

I putting on built heads and a mild cam this week.

Built, as in stock heads with some work done to them? If your running factory heads and a mild cam you will be fine with the stock intake. I would look into getting some LS1 injectors before a tune.

They are going to be stock heads built up. Do you have the part number for the LS1 injectors?
