I recommend the JP-3 or OFNA 086
Anyone with a better one, please post it, I'd like to know as well

porting on sleeve is pretty close to the same , crank on the 821 is drilled out to be lighter , 821 block has seperate diverters cast in the block for secondary rear intakes on the sleeve and new 25.8 mm rear bearing .

421bx had larger rear bearing tho didnt it??

sorry shud have worded it better... 821b v 421bx . i loved my 421bx, it was an insane motor, so if the 821b is even more potent, i dont think there would be any hassles in a truggy

I thought some S421B's had lightened filled cranks also. Does the 821B have a filled crank too?

Every Novarossi (6 head bolt) version I have seen has a lightened and filled crank, the "other" 421 wanta be's like the Top and Rex had what ever was laying around I think. I have seen them with balanced cranks, stock(un modded) cranks and some with on-road style port openings and others that looked as if they were for a .12. Only consistant engines I have seen from Novarossi was the purple headed 6bolted 421's. AND I LOVE THEM !!!!
