Ok, I am swapping a 350 into my 91 RS in a week or two and am looking for a manifold. I can get a Performer RPM or pretty much any Edelbrock Intake for about $65 bucks. I don't know if I can get any other brands that cheap or not.
The car is my daily driver and needs to make respectable low end torque, but I do want to run at least low 13's. The car has an open element and hooker 2055's will be going on with the engine, gears, heads, cam, and converter are future mods. Like I said, I want respectable low end, but good high end
I'm kinda leaning toward the Weiand street ram 7525 I think, but I'm also considering the Performer RPM. Any other suggestions will help.

I vote for Edelbrock. They make some of the best intakes and the RPM is a very good intake. You will have PLENTY of low end as long as the engine is built with complimenting parts. I don't understand why people are so worried about the intake manifold. The only real difference is going from stock to aftermarket, not between different after market companies. Let me also say that a 350 in anycar will have plenty of torque down low. It's not like we're playing with a 4 banger. I would just make sure the torque converter is matched pretty good. You don't want to have a stock stall speed on an engine that doesn't make even 150ft-lb until 2000.

Thanks, that's the answer I was hoping for.
Looks like it's a Performer RPM for carb with adapter for me.

where can you pick an edelbrock
intake up for $65??? im trying to
find one myself... how much would an adapter
kit be for T.B.I??

This local guy sells them. I think summit sells the adapter plate

Well, dammit. The performer Rpm does not come with EGR and I am not into prom burning yet. What's the next best?? Also, found out the local guy was bs-ing me, he doesn't sell them for 65, and doesn't even have the ones I need.
IS there a way to get around EGR withput a custom prom tuning?

Is the Performer TBI manifold for 350's? It's not terrible...

And what's the PN for the adaptor? I might need it!!! =D

I've heard and read that you will get better torque curve throughout the RPM range with a 4bbl performer used with an adapter plate but not the 454 adapter it won't atomize well. I guess the performer TBI doesn't quite hit the numbers of a 4bbl performer adapted.

yeah those 4bbl carb intakes work better than the stock tbi manifold cause there's just more plenum volume so there's a bigger resevoir of air/fuel for the cylinders to draw from.
