I wouldn't worry too much, I went from an AeroVee to Jab3300. My empty weight went from 301kg to 308kg on an 'A' model, all of the weight gain was firewall forward. My empty CofG works out at 22% MAC, which works better than the VW with me sitting in it ( I'm built like a brick outdoor dunny ). I'm certainly interested in how yours works out....lighter engine, but more weight in fuel tanks but closer to the CofG. Now as I like to put my money where my mouth is I reckon that your aircraft will be at most 3/4" rearward CofG than mine and similar weight provided you haven't put too many shiny toys in the dash. Good luck!
