In the cases where that is sufficient, good. However it usually just shows up the shortcomings of the piston-ring package__now that the top-end seals so well__and you wind up having to go right back into the engine.
If the cylinder bores and pistons (ring lands, primarily) still fall within specs__even if only marginally so__adding a new set of piston rings & rod bearings is a better economic choice, and can all be done without removing the engine from the car.
My personal opinion though, if you're going to go that far, why stop short of replacing the main bearing shells and timing chain?

Randy, I see where you're coming from but on this (and many other forums) there seems to be an uncontrollable desire to spend other peoples money. Evey fix includes "while you in there why don't you do -----". I have no quarrel with doing the job right, whatever it is, but many times it is gross overkill. Not all of us have deep pockets.
Not in many years have I heard of a big Healey being used as a daily driver. I am sure most are part of a 2,3,or 4 car "fleet" and if I may speak generally, I would guess most are not driven more than a token number of miles, 1 to 2 thousand per year would be a lot. Does a car used that much NEED to be perfect ?

I put 4,850 miles on my BJ8 on one road trip last year; and another 1,000 or so just puttin' around. My car's far from perfect at nearly 200K miles total, but I want/need it to be reliable and strong when I go places like this:
The BN2/100M doesn't get driven nearly as much, but it's not the luxo-barge the BJ8 is.

Did you say "special crank".....Why yes, I do have a special designed billet steel crank good to 8500 RPM, but I hope not to go there.

To paraphrase Bill Cosby's line from "200 m.p.h.", "Where can you turn 8,500 rpm in a Healey?" "Any side street."

Yikes, that's gorgeous! I expect it cost more than my Healey's purchase price too ($4200, freshly restored in 1978).
Just for the sake of conversation, and based on the circle of racers you run with, what's a stock crank good for; assuming all internals are properly balanced, and the valves don't float?

Thanks, my MSD is set somewhere around 5600-5800, but it only sees bursts and rarely anything sustained above 4k. Fingers crossed...
