They are supposed to be Convex, not Concave.I am pretty sure they are supposed to be concave, so the lifter rotates in the bore and wears even on the lobe
Yes will be going through everything shortly as the rest of the engine comes apart.you will need to go through the entire engine and clean it. Freshen rings n bearings as requires. Your heads probably need a split.
Post the flow numbers?You did not say if you are using an 850 CFM carb?

The lifter pictured is well on it's way to failure....cam lobe nose will be similarly worn.
Waylon, I think your assessment of power peak for the #110275-10 is going to be about right, might be as high as 6200 rpm since you've got decent heads
I can live with 6200 as that's still pretty reasonable. The only thing I'm worried about is my power brakes with the @.050 duration well over 240. My power brakes are fine now except when the engine idles really low like at start up.
700R4 with a 2500rpm stall converter. Seriously considering going to a 3000-3200 rpm converter while the engine is out. 3:73:1 rear end gears. You're probably right about the first cam being better for the combo right now. I street drive the car a lot too an the first cam would for sure be fine with my power brakes and such. I drive the car ~20 miles each way to work in the summer when the weather is good.Yes. Convex.
Considering just the engine combination, in my opinion, the smaller off the 2 cams seems like a better fit for the combination right now.
What do you have for a transmission/converter and rear end/gearing?
I'm more worried about picking a good cam right now. Won't be back to the track for 4 or 5 months anyway due to winter. My 'meh' 1/4 mile times are a product of not enough converter(supposed to be 2500rpm stall, but is a 12" unit), mediocre heads, 1 5/8' headers.those cars usually go 12.0s with what you have?
Lets say your combo is 300 lbs over weight thats still 12.3s?
Lets figure out your issues,,,
Yeah, the exhaust is weak on the Edelbrocks. I originally picked them up several years ago for a 350 used in a pickup truck before I got back into working on engines. I've been soaking up as much knowledge as I cam about head porting and did some mild porting and valve destrouding on a set of 882 heads that went on a 327 for practice. Thinking about cleaning these Edelbrocks up some while I have the time. My calculated compression ratio is 10.7:1.just looked at your head flow numbers. The int/ex ratio is terrible. Its like an FE? You need 10º extra on the exhaust side. I would use split ratios and a moderate cam profile. If you like 106º icl I think 110-112º ecl with 8-10º extra on the exhaust side. If you buy AFRs or profilers later this camshaft will suck
