Hi Ken, Good luck with your G. When you are looking for a big part, let us know where you are located. "Without digging too deep", here's how you tell a 375HP from a 400HP 300G engine. 3084 vs. 2903 carbs cast iron headers vs. log manifolds 2.5 inch exhaust all the way "short" rams solid lifters 3-speed manual trans only (available on 375-hp, but rare) should have bigger alternator pulley probably manual choke I'm not sure on colors, but the 400-hp F air cleaners were red. Let me know if you find one! Best regards, Andy __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable. Sign up now. http://mailplus.yahoo.com
