440 cam help

I don't have any math , but I do have a real world example and a story. In 1986 I was 20 years old. I had a 71 RR with a worn out 383. Went to the junkyard and bought a 440. Opened up the PAW catalog and ordered the cheapest forged pistons they had (TRW 2266). At blueprint spec these are only about 8.6. I read an article on pocket porting and decided to do that to my 906s. May have done more harm than good . Who knows? Had block bored, rods resized and valve job done . Ordered a big ole Comp 292 Magnum. 244 at .050, .501 lift, 110 LSA. Advertised as making you sound like the "king of the drive-in". Matching lifters and springs. Stock rockers, pushrods and valves. Used the factory iron intake and Holley vs 750 . Cheap headers. Operating on a very low budget. I think I had 1300 in the entire motor. Had a stock torque converter and 3.23 gears. Went low 14s at 102 spinning the crap out of some worn out N50s. I borrowed some old hard "cheater" slicks from a friend and squeaked into the 13s, still with a little wheelspin. Factory converter gave up and I got a cheap Neal Chance 10.75 ,pretty much like a factory high stall. Would only flash to about 2500. With some new 28x9 M/T slicks I went 13.50s. Was it soft on the low end? You wouldn't know it with street tires. With the slicks you could tell, but it's not like it was an absolute turd off the line. It was just that it really came alive over 3500 rpm. They didn't give 60 ft times at our track back in the 80s. In the 90s, the engine got new rings, bearings, timing chain and lifters and went into a 68 Satellite. 3.23 gears again. I put a 6 pack hood on it . Swapped out the stock iron intake for an old Torker. Went 13.24 at 103 on 235-60/14s and 2.5 exhaust. I put in a 10 inch GER converter (flashed to 3500ish) and with the slicks and open headers went 12.80s. Weld Draglites on front and ditched the 50 lb heater box , tuned a bit and went 12.60s. Traded the 750vs for a 750dp and one inch open spacer and went a best of 12.35 at 107 with a 1.69 60ft. The engine hasn't been apart for over 20 years. Sometimes it gets driven almost every day and sometimes it sits for months. All kinds of weather. A lot of short trips( I live close to work). Infrequent oil changes. It's tired and has a lot of blowby. Only broken part (so far) has been a hole punched in a rocker arm. And that old slow ramped Comp 292 hasn't gone flat yet. Oh yeah, the 292 sounds awesome in a 440.
