89mm or 92mm

I have a 89mm ls lightweight eagle crank. Was gonna use this for my b18C5 all motor build.
But I was thinking maybe I could get away with a 92mm crank and still have a reliable DD driver? With Kingmotorsports tuning it. What do you guys think, is 92mm reliable and good for DD? Was gonna try to get a 92mm scat crank.

you would need custom rods and pistons to go with the 92mm crank..... $$$

how much more power, hp and torque wise, will the 92mm make over the 89mm? with everything else like pistons being same compression.

Re: (chueflee)

try directing your questions to King Motorspors or whoever would be building your engine since they would be the best ones to give you advice on power differences, costs, reliability etc. This forum can only give you opinions and no guarantee's... hardly what you need to build a reliable engine.

A 92mm crank can be reliable in a daily driver
