It is a dual plane intake (Dart Sportsman- I think it's a knock off of the Performer EPS). Haven't done cranking pressure yet...will throw one on it this weekend. Bought a pump cam assortment and some .35 squirters (just in case- I will try to tune with cam first). The idle air fuel was set at operating temp fully warmed up (also did the vacuum gauge thing and got it to max out at 13 from 12 or so). Cam definetly sounds lumpy for what it is but I guess that's what a solid cam leaves you.
