I think you should race my little LG4, would be a close race.

Do you know what mod's he was running - he was obviously not stock.

Re: Little old LG4

LG4 is fine. Everyone hates on the 305 but with the right elbow grease and money it's still one hell of a street car.

The LG4's worst enemy is that sissy little cam' that GM gave it. Switching the cam' alone to a Competition Cams cam, is always the biggest gain in HP second to a huge shot of NOS. With good bolt-ons, proper weight reduction and upgraded suspension, there is absolutely no reason you wouldn't get into 14's.

Re: Little old LG4

What cam and supporting mods would give it some more power?

Ask and you shall receive. http://www.goingfaster.com/spo/modthel03.html.
This configuration is for a TBI setup, however if you scroll down to the bottom you can pick which flavor you want. All done with a carbed system.
