okay now, if you're in my fan club you know i have this 1974 400. well, after staring at it for over 6 months i just tore into it and this is what i found. true 400 with 882 heads.(stock????)
like new, i mean like never ran, main and rod bearings dated '92
(i've only looked at one each)
new lookin oil pump that has never seen oil, ditto dist bushing
thin caked on oil on rods and crank
brand new, never seen oil in the galley, head gaskets
thin caked on oil all over the push rods and rockers and heads
lifters look like total crap, caked oil etc
cam looks like hell
cylinder walls have never been honed, VERY small ridge visible
timing chain cover doesnt look like its been off, but had new intake gaskets because last guy put a 2bbl intake/carb on it
oily sparks plugs that seem to match the heads
did somebody actually just rebuild the whole bottom end, why put old heads on? but they did just that. i know i need to check ou the heads and i plan on making this my second port matching job and first pocket port job.
Q: So: should i pull the pistons out and re ring it? that means pull out all of them and the crank as well. pistons are dished, and have four notches for vavles on each side of each piston. there is no noticable movement in the cylinders of any of the pistons. if i have to pull out the pistons, shouldn't i just get flat tops and what will i have to do/get as far as the notches go. i dont think you'ld need notches with big 76cc 882 heads, but i dont know nothin bout 400's:surprised. and as far as the steam holes go, the heads have them, but the hole for the water is as big as a BB in the gasket. should i enlarge to the size of the engine/head holes??? i am building this just for an interum engine for when i pull the 350 out of my camaro to build, but in the end it is going in my 40 tow truck, so i want the mill to last awhile. this was really a halfassed motor rebuild. my usual, crap:spank: i always inherit somebodys BULL crap, why couldnt it have venolia pistons and 'lumee heads? this engine supposedly came out of a 74 caprice. it has sat, unrun in a van that followed me home last year for at least 7 seven 7 years!! these heads are good to go on unleaded gas i believe. ALL REPIES APPRECIATED, BUT ONLY IF YOU SOUND LIKE YOU KNOW WHAT IN THE HELL YER TALKIN ABOUT!! other ones still appreciated, just not as much
