Thanks Sean!
Kind of interesting, but your Dyno2000 is pretty similar on the torque curve but a little more optimistic on HP, and a bit flatter on both curves than my Perf Trends shows for my 410. Guess I'll use yours for bragging rights!! Steve

I'll replace this post later with a graph but you are making a peak of 513HP@5,000rpm and 580ft. lbs@3,500rpm. I would suggest moving up to one of the comp cams rollers as they are a little hotterthan the crane's rollers. Unless of course you are going to drive this on the street everyday. Then you have the perfect cam in my opinion.

Is that last setup a 427 with 428 crank?
I think I answered my own question. That must be one of the new SCAT or similar stroker cranks.

It is a 406/428 block bored .030 with a 4.25" stroker crank from scat. That should make 458 cubes. If I were lucky enough to get a 427 block to use with that crank, we would be lookin at about 480 ci. That would be sweet. I have an uncle that has a few 406's, and hopefully he still has them and will lend me one for a small sum and I may take it .040 to get a full 460 ci. Thanks for the help ratsmoker, I really like those numbers. And NO WAY am I driving it every day.

Well i went to Comps website and I couldnt find anything hydraulic that was hotter than the Crane accept for the Magnum 292 but I don't want a single pattern cam. Is there a cam that you have in mind that I should check out?

You do realize that the cam you are mentioning is a hydraulic roller right? That is no flat tappet cam. I was looking it over and the cam you chose would definitely be the ticket. The comp cams are hotter but loose a lot of torque. The cam you chose will increase the price of the rebuild about $1200 over a regular flat tappet cam.

Yeah i saw that but I guess now is the time to clear the air. What's the difference between a hydraulic roller and a regular hydraulic cam? Also, what has to be used with the roller cam that adds an additional 1200? Im guessing rocker arms are around 5-600 alone. I was hpoing I could just get everything in a kit so i wouldnt have tro mix and match a bunch of things. That's mostly why I liked this cam, because I was told that it would maintain a lot of torque as well as high end hp.

At a minimum you will need a roller cam ($300), roller lifters ($400), custom pushrods ($150) and a whole new rocker assembly ($600). Roller rockers are not required for a roller cam but Heavy springs ($150) are reqired. A roller cam of any healthy size is going to require either the rocker assembly (as noted above) or at a minimum: hardened shafts, better stands and possibly end stands. It is just plain expensive. You wouldn't want to use the standard replacement valves either. They probably wouldn't last long. I hope hot rod didn't use the stock rocker assembly for their build as it will surely break. My non roller .580 lift hydraulic cam has broken two stock shafts. Hydraulic rollers work the same as flat tappet hydraulics but of course have rollers on the bottom instaed af a flat surface. You should be able to see many pictures on Crane's website. That cam is an awesome cam for a hot street engine or a heavier drag car/truck.

I will see if I can get to posting some more graphs this weekend. I am very busy right now with the job and all. They like to do combat excercises a lot here in Korea.

4) Performer RPM Intake
5) 10.4 CR
6) Hedman Headers through Flowmasters
7) Cam: Crane 343801, 278/290
