236/242 .605in/.615ex

I know its big, but its not a daily driver and milage sucks as is, have all the goodies to support the #'s but......

 

If you have heads that give you good flow numbers right up to 0.650-0.700" lift, it will make good HP. And assuming you have the required PTV clearance for that much lift. You also need to have the spec for the lobe separation angle, which will give you a little bit of direction on how good the street manners are going to be. I run a 230/242 114LSA, 0.590/0.590 solid roller, and its actually very mild with a smooth 800rpm idle. But the 381 cubes contribute to that. On a 350 it would be a bit more "aggressive", as it would also be with a 112 or less LSA.
