No. I am not sure that the original bolts are too weak.

I am highly suspicious that they fit too loose in the rod, and they don't
properly position the rod cap. This would be a very marginal situation for
a street machine, and totally unacceptable for any sort of serious
competitive driving.

New original-type rod bolts are available from both Sunbeam Specialties and
Classic Sunbeam Auto Parts. The prices are in the three-dollar range, plus
or minus a few cents each. Being original bolts, however, I would expect
them to behave as such. I would thus expect them to fit too loose in the
rod, and to not properly position the rod cap.

I'm sort of new to this Alpine stuff. But from what I've encountered so
far, I feel pretty confident in claimng that I can build two very nice Tiger
motors for what I'm going to end up spending to produce one very nice Alpine
motor. With that sort of "investment" on the line, I view the extra forty
or fifty dollars for rod bolts to be very minor if it helps keep the whole
thing from coming apart at seven or eight thousand RPM.
