That Comp is in my brother's Edelbrock Rpm headed 493, 11.4 to 1. Replaced a 300/.639 Howards, and solved some of the detonation issues he was having while driving on the street with 91 octane in the tank. He really likes it on the street.

Aside from bleeding off pressure, how was the torque down low and mid........?

About the same as the Howards. We hurt the launch with a tighter converter, but the mph was the same, it's far from sorted out, Weiand tunnel ram with 750's. 11.04-121, 3850lbs, and less aero than a 4X8 sheet of plywood.

Dom , don't you run 470ci and a roller ? sorry if I am wrong . my understanding is to go 2-3 sizes bigger over your 440ci choice when going stroker . I have 293adv,258@050 cam in current motor . Billy , I did see your input in the other threads . Yes I also run 98 pump gas . I am in the 120/122mph range now . but a little inconsistent et wise . I am hoping for around 615/625 flywheel HP I should hope to not shift above 6500 , I shift at 6000 now

Dwayne Porter nitrided my solid flat tappet for me and I would say its a good idea. I also run the EDM lifters. My solid flat tappet is 264 and 270 @ .050 with .585 and .592 lift and a 110 LSA. And my eng is 10.6 comp as it runs fine on 92 pump. Ron I agree w/Ron regarding nitrating. I also went that route and used the Comp Cams EDM lifters. Just good insurance.
Ok

Not enough head for those cams.Saying it in a nice way not to hurt anyone feelings. Scrap...the problem is not enough head for the cubic inches, hence the need for that much duration. Can't wait to try that Comp grind with some nitrous...

Run the Lunati if you have to pick from one of those three. The tight LSA and big duration will hurt the low end, but you have a 5000 converter and 505 ci. It will also come on like a freight train in the mid range and fall off early because you have a limited cylinder head and 505 ci. And finally, it doesn't matter if it falls off early because you have 4.10 gears and 505 ci. You also want to drive it daily, so you might as well make better mid range peak power where you can use it, than better average power where you can't.

I tend to agree with thisview, especially if the heads are stock. Anything above .600 lift will not be the best choice. Ragnar Not enough head for those cams.Saying it in a nice way not to hurt anyone feelings.

I agree to a point about peak head flow being the limit that`s why I go bigger in lift and duration that way I pass the peak on opening and closing and believe P-body does the same thing iirc.......
