GriffsMonte Posted August 2, 2015 Share Posted August 2, 2015 Guys and Gals i need some help, I just bought a truck to haul the Monte with once she is finished, 1979 Chevy C-30 with 454 mated to a th400. I figured you all could help answer a few questions. 1.) is whiteish smoke out of the tail pipes a sign of a lean condition ? i think the #1 is fouled 2.) what size carb do you guys recommend for a 454 ? the guy i bought it from put a eddy1406 on it. which is only 600cfm and it seems to surge at low speed(around 20 mph).

Sam (Bones) Posted August 2, 2015 Share Posted August 2, 2015 white smoke is usually water or antifreeze does it clear up when warmed up? a 750 cfm is plenty for a stock/mild 454 Quote Link to comment Share on other sites More sharing options...
GriffsMonte Posted August 2, 2015 Author Share Posted August 2, 2015 No signs of it being a water issue. i changed the plugs cap and rotor a week ago and no smoke after that and yes if i drive for about 10 minutes or so there will be no more smoke out the pipes. i figured the timing was of and the small carb wasnt helping the situation either Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted August 2, 2015 Share Posted August 2, 2015 it's just burning off the condensation Quote Link to comment Share on other sites More sharing options...
GriffsMonte Posted August 2, 2015 Author Share Posted August 2, 2015 ok well im going to get it tuned up by my engine guy this week hopefully. Do you think i should upgrade to a bigger carb before i get that done ? or will the 600 be good enough Quote Link to comment Share on other sites More sharing options...
mikenewman Posted August 2, 2015 Share Posted August 2, 2015 needs bigger carb before tune up so he can tune the carb to the motor. the white smoke sounds like a head gasket is seeping at worm conditions. after it sets take out the plugs more than likely find a plug wet Quote Link to comment Share on other sites More sharing options...
GriffsMonte Posted August 5, 2015 Author Share Posted August 5, 2015 Thanks for the help on this one guys, i actually got a bigger carb for it an eddy 750 cfm and it's running a lot better. looks like the motor was just starving with that 600 Quote Link to comment Share on other sites More sharing options...
