Sorry it took me a couple days to get back to you. The board didn't let me know that anyone had responed. Anyway, i wasn't sure the exact spec of the engines they came out of so i went back through my notes to look up such info. Unfortunately i couldn't find any pertinent info. So to answer your questions i have to say i'm sorry, but i don't know the complete details of the engines they were pulled from.
What i do know is what i had listed before. They came out of mr2's, they are yellow tops, high impedence, and they are 370cc's. I would be more than happy to let someone check these out however they see fit. I am confident there are in 100% working order. So if you need some 370's, or think you may need/want some, just let me know and i'll work with ya. Once again, thanks for looking.
