440 Cam selection help
Hello I'm looking for advice on an engine I'm building, for my 67 barracuda. It's a 440 out of a motorhome. I've had the block bored .030 over and have 2355 speed pro pistons for it, these pistons advertise 7cc valve reliefs and a compression height of 2.061. I have seen reports of these pistons being .010 - .020 in the hole, I will measure when I get them installed after I get the rotating assembly back from balancing, I dont mind to get the block shaved to achieve a certain deck height if needed. Right now my plan is to use a set of aluminum 440 source heads, these have an advertised 80cc closed chamber. With a .027 cometic head gasket summits static compression ratio calculator is showing 10.29:1-10.5:1 compression ratio. This would also put piston to head clearance at .037-.047, for quench. Plan on running a Holley SD, or Edlebrock performer intake (I want to run a Thermoquad with a stock choke set up), and Schumacher tri y headers. I am now looking to decide on a camshaft (plan is a hydraulic flat tappet). I also plan to use factory style stamped rockers. I want this to be a very street able daily driver type build. The car will see mostly 55 mph roads and city driving. I have 93 octane fuel available anywhere in my area. This is the first engine like this I've built so I wouldn't mind a lope that you can tell is there. I called Oregon Cam grinders and was recommended his 1176 grind. The specs on this look very similar to a comp XE274h cam. I have attached photos of the provided specs on the cam. I plan on running an A833 non overdrive manual trans. Oregon Cam grinders recommended 3.55- 3.73 gears. Looking for any suggestion on cam before I pull the trigger and any suggestions on any part of the build are welcome and appreciated. Thank you for any help.
