Guys I know the cam thing has been discussed at length many many times, but was wondering if you could give me some advise on an off the shelf grind for my new motors. I am currently in the middle of building some 572”, 8.5-1 engines with ProMaxx 317 heads that Valeko had worked on the exhaust side and now chamber porting as well. They flow 375 at 650. I have super chiller intercoolers and BDS 12-71 blowers with quick fuel 1050 blower carbs. I will be installing Daytona Sensors ignition as well. I plan to set them between 8-10 pounds of boost. I currently have 254 264 @50 and .632 .632 lift on a 112ls. My exhaust is a dry Imco Powerflow system. If you guys could pick me an off the shelf cam to maximize these engines to their full potential, what would you pick? I feel like my cams are decent for the project, but if I buy new bump sticks what should they be? Also I am using 1.7 rockers.

Jim probably mentioned to run 1.8's on the intakes with that cam. Just a guess. Lol... Your gonna make a chit load of power either way. Is Earhart gonna dyno? That's a good proven cam and easy on valvetrain. Would be nice to have a little more lift if your going for max hp but.... Did Jim say what he ended up with int CC's. If I recall mine ended up at 347.

We are just working on the combustion chambers this go around. My budget is being stretched as it is.... the chambers ended up at 128cc. I am going to leave the cams as well. I really think they are going to be very close to being ideal. I was at More Power on Saturday for about an hour and I think I will have Dick Dyno them as well. I am starting to think I could hit 1000hp. What do you think?

I think you'll hit 1,000 hp on the conservative side. Big cubes and big blowers with chillers makes for some awesome power. I'm glad your going to more power. Much closer to you also. Dick and Duane great guys. I practically grew up there living only a couple miles away years ago and have a great relationship with them. 6-8 lbs of boost you thinking? Let me know when your going to dyno if you don't mind. I'd like to come down and can help set up etc and get away for a day or two. I've got to bring some engine parts down at some point anyway. I'm happy and excited for your builds. Hope your drives feel the same. lol...

Yes we are going to set them up somewhere between 8-10 pounds. I am really looking forward to the process. I have never had an engine dynoed, and never actually seen a engine dyno live before. Dick has been very helpful! I would have no problem with you coming down and taking part in it!! Who nows maybe they will sniff 1100.....:). The drives are not going to appreciate it, going to be building a spare until I can upgrade to something with some more structural integrity.

Just keep updated. You will have a riot and great experience however being your first time you'll likely chit your nest thinking that your hard earned engine gonna scatter on dyno right before your eyes. I'll be there for sure. I don't see 1,100 out of the question what so ever with that boost. I would think you'll see that near 6,000 rpm with a nice torque curve.

Kinda funny we flipped builds. I started out NA to SC and back to NA due to current trans and drives. You started NA and went SC. It is what it is.
