Okay, ive been working on a 440 for a while. 2 plane weiand with 750 street demon. Put a whiplash stick in it, im at 25 degrees / 12hg initial and 37/8 tot (mayby a bit high), closed chamberd 452 heads 79cc heads with newly grind valves. New crosshatch in cylinder bore and new piston rings. First startup. Run the cam in for 20-25min went well. It smoked ( white ) from exhaust on idle and all over the powerband, but it moved pretty good. my tires were smokin the 1gear without even trying ( 4spd A833 ). So i order new rings, got it crosshatched and put them in. the old ones didnt sealed and cylinder was glazed. First startup - No smoke from exhaust. drove it for about 40min got home parked it in the garage. Next day took the initial down to 18 + 20 = 38 a 10hg on vac. changed a stepup spring for lower vaccum.. took it for a spin, feels a bit weeker on the powerband ( throttle response ) so got it back up on initial again and more vacuum. The more initial he gets the more idle vacuum i get so ive been tuneing after that. But now i started to see smoke ( white ) from passenger side exhaust again. a bit on startup not while im driving but as soon i stop the car and check on idle i see some white smoke puffin.. My oil still looks like brandnew, no bubbles no nothing on dipstick. exhaust condensation doesnt smell, taste or sticks on the hand. I dont loose any coolant but i dont get alot of heat in the car? figure i need to bleed it? Every gasket ive took of is brandnew aswell. Its the smoke thats gets me, thats why i changed the piston rings and cleaned all the valves. Does it need more time on the road? Ive drivin it like 1.5 - 2 hours so far, like normal but not on high revs. Im clueless on the smoke? But i got some more tuneing to figure out on the carb and ignition thats for sure, but im learing as i go. I would greatly appreciate some feedback on this, the summer is nearly over (like 2months left) and i cant stand the white smoke on idle.. should i pull the heads again and try new gaskets or get some more miles on it first?
