Hi..
BTW, when I rebuilt my 1622 for my MGA, i pretty much did the same thing... a little omph...
oversize pistons, a more respectable cam. shaved the head .050, balanced, polished rods, lightened flywheel etc. etc.
The car is still long from being a pocket rocket, but, i can cruise at 3500 to 4500 without feeling as though i am abusing the engine...
Be sure to check valve clearance.. I thought i had enough with what I reduced the head by, but after about four instances of breaking valve rockers, finally took the head off , and sure enough, I was just kissing the top of the block...
landed up flycutting the block.. no problem since..
I always say, if you are going to rebuild and machine, why not just emphasize it a bit.. really does not cost that much more in the end...
sorry no dyno for horsepower...
