I am needing a gas engine that can swing a 18x6 or 18x8 (tops) comfortably. I was leaning towards a G26 since the G38 has the rear exhaust and would likely cause mounting issues, I know this as I have a old G38 already with a Bisson muffler on it and it would conflict badly with the firewall. I have considered a custom exhaust but don't know what is available and am trying to keep cost down (I don't need a custom scale $300 setup). The G38 almost seems like too much engine for a 18x6 but the G26 almost seems a bit small to get the 18x6's full potential. Opinions?
