Or even the 60244 cam, has a little more duration.

My cam is a little big. It would be in the .585 lift range and .245 @ .050. Its single pattern.
I say high 11s with E heads.

I thought the 455 @ .60 over was a 469 CI. not 462 CI. I thought that the 455 @ .30 was the 462 CI ? Any way I was just kind of guessing what the power level would be at 500 HP with this combo , so if I'm off I don't really mind but I know that when this combo was in my car at .30 with the 455 I had plenty of TQ so I guess I don't need any more in that area, but would like to have the same amount of power as before but with a little bit better idle quality because even with that combo before if I were trying to run in 4th gear under 35 mph it wanted to buck a bit & in the 400 .60 over combo now if I run under 30-35 mph it doesn't like it much & wants to buck a bit even even with the 3:73 rear gears. I don't know if I'm asking for to much but this is what I'd like to do. I can live with the slight bucking in 4th gear if I have to as I like the amount of power I get even in the 400 .60 over combo. The 400 is all the same parts that will be going in the 455 + .60 over. Right now the E-heads are on the 400 with the RA IV cam & all the other parts that I have stated that will be going in the 455. Also what brand is the 60243 cam. You didn't say who makes this one ? Let me know Please. GACH how big or what is the spec's on the 60244 cam ? I try to get on at least every 2 days but I would like to be able to be on here every day, but my schedule is a bit tight right now as I put on a car show cruise ion every Wed. & we only have 2 Wed's left & every body & their brother is calling to get info for the last few shows which take up a bunch of my time & with all the extra planning for these last 2 shows I need to focus on these last few right now so forgive me if I don't answer right away. Anyway thanks for any & all the help you guys are giving me. Thanks Rex.

My mistake, 30 over is 462. It's a Crower cam, I'll look up the spec's and post them for you.

60244 cam spec's

Performance level 4 - Ultra-Performance Compu-Pro - The following grinds are best suited for dual purpose hot street/drag strip situations. These cams exhibit strong mid-range and top end torque and horsepower. Headers, dual exhaust, larger cfm carburetor, performance ignition and 11:1 compression are a must. Cylinder head modifications would be beneficial. Use with standard transmission or automatic with high stall converter. Low gearing a must.
INT/EXH - Dur @ .050 Lift: 239/241 RR: 1.5/1.5 Gross Lift: .500/.500 LSA: 112 RPM: 2000-2200 to 6200 Redline: 6500

60243 cam spec's


Performance level 3-4 - High Performance Compu-Pro - Intended for the performance oriented hot street application. These cams offer an extended rpm range with emphasis on upper bottom to top end power (strong mid-range). Performance gears, headers, dual exhaust, larger than stock cfm carburetor, performance manifold and increased compression (9.5:1 to 10.5:1) are required. Works well with automatic transmission if matched with proper ring and pinion gears and/or high stall converter.
INT/EXH - Dur @ .050 Lift: 228/235 RR: 1.5/1.5 Gross Lift: .479/.494 LSA: 112 RPM: 1600-1800 to 6200 Redline: 6500

Do note the Lunati 07702 in post #57 is a single pattern cam.

In the opinion of many the Crower 60919 is so close to being a 041 clone that it's characteristics would be similar.

Since crower cams are being mentioned here, and not necessarily a recommendation, but if it helps for a general comparison my engine builder used a Crower 60211 hyd flat tappet (236/242) cam w/1.6 rockers in 4.250 stroke combo using 87cc Edelbrock heads, cleaned up only no port work to speak of, 10.3 compression. It used a Performer RPM intake, Holley vacuum secondary 750 carb and 1-7/8 headers. On the engine dyno it made 513-518 hp at 5200/5300 rpm.

Actually Steve I like the Crower 60211 better but is says rough idel. I've used in in a couple of builds for friends. One guy with a 400 ran 12.00's. It's on a 108 which tends to have a rougher ideal compared to a 112 or 110. It's definitely a good cam though.
