For blow-through? 48mm Weber/Dellorto for simplicity of setup. Holleys are another option, and there is some blow-through information available for them (theturboforums.com is a great resource).

For NA? 500 CFM Edelbrock Thunder Series. Getting it to work on a rotary is just a matter of tuning. They have adjustable vacuum secondaries, too, which is pretty awesome. Just be careful that your manifold is tall enough for the carb to clear the water pump housing.

OMP lines can go into the manifold. Jeff20B installed some brass fittings in my LIM for them. If you go turbo, remember to clamp the lines so they won't pop off under boost. You will have to either figure out an OMP lifter rod or wire it open. Or if you prefer, you can always just premix.

Oh, and as far as carb hats go, don't expect to find them any easier with an off-the-shelf carb. On the contrary, it's easy to find Nikki carb hats: just go to Robert! I couldn't find any carb hats for Webers or Holleys at all when I looked (well, I did find one Weber one, but the inlet was in the wrong orientation). It's all custom, it seems. Robert will make you any carb hat you want, but his Nikki hats are the cheapest, IIRC. I settled on making my own due to lack of fundage.

if i dont make my own intake would the racing beat intake be a bad idea would it work with that carb?
iam really a carb noob, would i have to run lines since its has vacuum secondaries. or is that all ready setup on the carb it self.
the rb intake all ready has a vac line for breaks id all so have to tap for timing advance and the omp lines correct?
