a good price is hard to define.
when the 101 bolts were everywhere they ran about 6 to 8 bux per pair.
re-using them was o.k. but only once if you wanted to be sure.
at the same time the standard mc91 bolts were around 2-4 bux.
those you threw away every time you pulled out the con rod.
bonbrights bolts were something like 14 bux each but were reusable for at least several times.
now mc91 bolts are about all gone and finding mc101 con rod bolts is getting really hard.
i have no idea about current pricing as i've had a big stash but now they are running low.
the problem is getting a bolt that small to be that strong requires special processes and alloys.
typically aerospace or military grade and spec.
if you've ever research something like that you'd find they are NOT CHEAP.
right now the best price i've heard is right around 30 bux each from us motors.
getting them to actually ship some is sketchy at best.
if we get them back around 14 bux each that would be an acceptable price.
the stronger 260ksi bolts can be re-used at least a few times safely .
even if i could re-use them just once that would work out for me and most engine builders.
terry ives figured out a general spec on the bolts that'll fit both motors.
the spec will fit mcculloch rods about 1+ threads past shoulder.
fits west bend 820 about 1+ thread short of rod shoulder .
both would be well with-in safe spec for motor.
if you were running a stroked mc motor you might have to shorten the thread a tiny bit .
hopefully we'll get a new supply soon.
