Just my 2 cents worth...I have this cam in my .030 over 390 with Badger stock replacement pistons, Edelbrock R4B, Edelbrock 600 cfm carb and recurved dizzy. Idles smoothly at 750 with full vacuum advance and pulls strong through 5500 rpm. Idle vacuum is around 15 inches and cruise over 20 inches.

YOU are the rev limiter Are you running the stock rod bolts like I am Matty? I'm going to try to keep my RPM's under 5500 just because it would be a shame to put a window in a 401 block my old 360 never complained about 6000-6500 with the stock bottom end but you can find 360's stacked like cord-wood for pennies a pound Glad to hear it's moving around under it's own power, I bet if you set the idle real low the cam will lope like you want

Well, I checked the piston to valve clearance with a little hobby clay, without any gasket (since I didn't have a used one here), I was worried with the close lobe seperation and .564" lift the intake might get close to the piston yeah, it doesn't. Those stock cereal bowl pistons sure give you lots of valve clearance valves don't get within a mile of them with this cam Just thought I'd follow up on it here since I mentioned it earlier in this thread.

The chambers do look different/more modern/better to me, but if they're 54 cc's they'd still drop compression ratio compared to the 51's. I think I might scrape 9:1 with the thin stamped gaskets, or if I spent the money for thin Copper Gaskets, but with the Low CR stock pistons and Eddy gaskets I'm *thinking* it's in the 8.7-8.8 ballpark. I looked for the post where I remember Dennis clarifying which pistons were used for 9.5:1 but I got sidetracked before I could find it. Maybe it was on the other board(?)
They're 7/16", Jim was nice enough to include the 7/16" studs. If I was going to keep the 3/8" studs I was thinking about just running stock rockers (assuming they'd work), but it worked out with the 7/16" Cranes, so far anyway
That's pretty much what I'm hoping for, I still have the stock rod bolts so I don't want to risk spinning it too high. Self imposed 5800 RPM should be perfect for me. & I'd be thrilled with 13" of vacuum, I put manual brakes in the car a long time ago anticipating a stupid big cam that I never ended up with. If the vacuum is there I'll put the power booster back on. I'm hoping this combo will have a nice fat torque curve right in the middle, to pull the gears no problem, but hopefully it won't challenge the low-ish torque rating of the 2.64 T-10. I'll just have to play nice with 1st and 2nd gears I think.
