The Superram was the intake I was planning on going with initially but decided on going with a converted Single plain. Do a search under my name and superram, I researched the Hell out of that intake. I believe it will perform almost identical to a single plain but the single plain will keep making Power in the Upper RPms and a Superram will probably die out around 6000 Rpm. There is dyno graphs were the Superram made a additional 60 pounds of TQ over the Lt1 intake and a solid 30Hp Across the whole RPM band.

Your looking at 1,500 for the whole Superram setup, I did see one on Ebay about a month ago for the lt1 with a 58mm TB as well go for around 900.00.
I would just do a converted Single plain though, More space opposed to the superram, a hell of a lot easier to work on, and will probably make more Hp and about the same amount of TQ.

 

do you have a link where yo buy the single plain? and will it work on an lt4?
thanks

 

Well seeing as how an LT4 intake only works with LT4 heads... And LT1 intake only works with LT1 heads, I would imagine the superram won't work.

 

Who made that rule? I've got an LT4 intake on a set of LT1 heads. All you need to do is a little machining to make it fit. The Superram may require a little welding to extend the ports since the LT4 heads are raised runner. As for the single plain, generally those have to be converted to work with an LT1.
