i've heard a fuckton of rumors that 350 chev stuff bolts straight into K motors - mostly rods and rod bolts. tonight i even heard that the valves are the same too! i did a quick google search but i cant find any specs, should ask a local hotrodder or something at the ballina car show on sunday

as far as i know, gudgeon pin offset allows the conrod to be more vertical (than with 0 offset) when the compression stroke is really putting the forces on it as it compresses air fuel mixture for ignition. this is why you bend rods when you blow a head gasket and your motor goes hydro

i'll go you one better and get photos of the 3k/4k/4k ribbing differences. they are in my automotive photo album at http://www.pbase.com/superjamie in "K motor parts". dont laugh at my budget 3k engine stand Razz that motor's ribs would probably be more defined if i cleaned it

i'll get dirty on the weekend and have a look at the camshaft side of the motors too. i'll strip them all and weigh the blocks somehow. i spose the only real way to learn the internal thickness would be to get the bansaw into them. i know someone with a fucked 3k block, i'll ask them. i dont want the orange 4k block so i'll see what i can do in that dept too

i got some bellhousing bolts today from the wreckers, i would have taken samples to the bolt barn and gone "you give me hi-tensile these now" but i had none, i'll go tomorrow

i'm also taking my block in to get bored out 60 thou soon, and seeing what i can do about repairing my bigport head. the rocker bolt threads have only been stripped about 30 thousand times, there are helicoils inside helicoils. i've heard you can get the holes welded and retapped, surely this would come at a cost though :\
