Long story short 2500 miles in my cam is starting to go flat. Ended up catching it early as it pulled a rocker stud. Noticed a few valve stems worn from rockers sliding. The break in was by the book and went smoothly so I'll save those details and questions for another thread. Here are the current specs on my engine, fully machined and cleaned up, new bearings, etc, stock forged crank and rods, silvolite cast pistons, 9.5:1, .040” bore, lunati 10120702 (262/268) cam, pertronix distrib, rebuilt 461 heads 1.94 valves, 650 Holley "classic", edelbrock performer eps intake, ram horns, 2.5” exhaust. It’s in a 2500 lb model A, super T10 wide ratio (3.42 1st gear), 3.00:1 9” rear and 7.50/16 tires. (The gearing is the same as a th350 2.52 1st and 4:10s but I get a poor mans overdrive.) This current combo makes for a good driver, runs great, stays cool, smooth through RPM. It wasn't a dog, but I wouldn't call it fast or powerful. The mileage wasn't great either, (15 mpg highway at 2000 RPM). It would be nice to increase atleast one of those two things. I admit I didn't do much for tuning, the plugs always read right and it ran great virtually out of the box. So now I'm debating if its worth it to dump more money into these heads (screw in studs, valves) and continue going slow, or step up to aftermarket heads. Also unsure which cam I should go with for either scenario, though I'd like to match it to as many current parts as I can. Originally I wanted a pre-64 look, though I'm caring less about that so keeping camel humps is a nice idea but isn't mandatory. Will aftermarket give me a big noticeable change with my current components? If so what specs should I look for in new heads? If I go new heads it'd be nice to step up in cam size if possible, any recommendations? Is a hydraulic roller retrofit worth the cost to try and prevent this from happening again? I am leaning more towards tuning up these current heads but it would be nice to get more power out of this thing. Is there a better cam choice for my current setup than this Lunati 262/268 cam? Would there be any benefit to roller rockers? I had just ran normal steel rockers previously. Is there anything else I should consider changing or doing when putting this back together. (I will check the bearings and bottom end for debris when I get it on the stand). It's a street car, mostly around town with some highway, the odd long highway trip every couple of years, maybe a run down the strip once a year. Reliability is number one priority, second is for it to be fun to drive, I want more power but I don't have to keep tearing it down every 2500 miles. I also would consider re-gearing to a 3.50:1 but I don't want to render 1st gear useless. I had hoped spinning so low on the highway would have got me great mileage but that didn't seem to happen. Thanks for the advice.
