SRX540

Ive had previous debates on this with people because i hear something different from everyone that knows about these sleds...I had a v-max 540 bottom end on 81SRX top end but cant try it now because i didnt notice the crank was bent. I have the 440 bottom end but i didnt wanna use it for restoration purposes. I have heard that the two bottom ends have the same internal mass and internally are the same, also have heard the opposite. Going to just put together the 440 bottom end i got i think now.
