Zerrari GTO Posted November 6, 2003 Share Posted November 6, 2003 Hey Grumpyvette, You obviously know you stuff re: SBC engines. I have a quick question to ask.... I'm working on a Ferrari GTO replica on a 280 donor. I have a 350 w/aluminum heads off a 96 (I think) Vette. Anyway, these heads have the center bolt setup for the rocker covers and I want to find an unusual (exotic) looking rocker cover to give the engine a Ferrari "look". Please let me know if you have any sources. Thanks, J.P. Roberts Quote Link to comment Share on other sites More sharing options...
