After around 4 years I got my engine torn down tonight. Never a major problem with it--but its long overdue for inspection. Im posting some pics I took of various parts to see what ya'll think. I dont have the crank out yet, but theres some pics of 2 of the rod journals , rod bearings , pistons , and the solid cam. its a 493, Ross pistons, Clevites, Scott Brown solid cam, pump gas, eddy rpm heads. Never shifted the thing over 6200 . rod http://img.photobucket.com/albums/v225/solrizzo/rod2.jpgrod 2 http://img.photobucket.com/albums/v225/solrizzo/rod1.jpgpiston 1 http://img.photobucket.com/albums/v225/solrizzo/piston2.jpgpiston 2 http://img.photobucket.com/albums/v225/solrizzo/piston1.jpgcam lobes http://img.photobucket.com/albums/v225/solrizzo/cam2.jpgcam lobes 2 http://img.photobucket.com/albums/v225/solrizzo/cam1.jpgcrank 1 http://img.photobucket.com/albums/v225/solrizzo/crank2.jpgcrank2 http://img.photobucket.com/albums/v225/solrizzo/crank1.jpgamong other things---do those cam lobes look ok--or nice and worn ? Obviously im putting new bearings in the ol' girl...

that looks pretty normal. a simple freshening is obviously in order but the camshaft should be replaced IMO. i'd check the bottom of the lifters to see if they are still convex shaped. looking at the worn lobes, some of the lifters might be flat or convex now. how do the cylinder walls look? timing chain stretch? valve springs and guides???, etc. etc.

thanks for the reply D , lifters are Comp-they looked great to the eye, cylinders have some wear--will be getting those honed and inspected for sure---with new rings of course . the timing chain shows about 1/4" play ( pushing it in from a flat edge) . ! seems too much ? Havent looked at the heads but they were basic ported / gone through 2 years ago. Springs are new 8005 Isky a year ago. i didnt think that timing chain would get that loose after 3 years.....its a Comp double roller i think my "freshen up" deal is going to get expensive... LOG BOOK SHOWS 182 PASSES----PLUS MAYBE 30 STREET MILES ! doesnt it always happen like that ?

i did look at the lifters again today. Some look pretty flat , some ARE convex ...
There is some scuffing at the bottom of some of the bores and the piston skirts .
What are the causes of the scuffing - too little piston to bore clearance? The pistons were new Ross with file fit rings , 4.350 bore

Looks like normal wear to me as I worked for a local builder and we freshened roundy-round motors that looked similar after a season of racing. I agree about a new cam/lifters(roller if you can) would be nice and as an example, my car has roughly as many passes and a few thousand street miles and ran it`s quickest pass earlier this year. Why did u tear it down anyways? Just curious. I hope to freshen mine soon unless it sells. Good luck w/it.

ok...thanks guys. Thumper - i tore it down just to see how things were looking inside --it was due.I dont see any major issues Cab-- so thats a normal thing with Ross? - i guess thats "kinda" good news... I probably wont run the cam , hope to MAYBE go to a roller , i guess its back to pb&j / hotdogs for dinner for a couple months... Ted - tryin to talk Jimmy Mopar into flexhoning the bores (i dont have a flex hone---need to buy one i guess) , plus i wouldnt mind him or Steve putting another set of eyeballs on my junk while its apart .... Im sure i will miss something... if i put a roller in this thing yer never gonna catch me in that ol Dodge of yours......

Flex hones leave too rough a surface. I'd have it professionally properly honed if it needs it. With that little time it may not. I've used scotchbrite wrapped around a rigid hone to get a fresh surface and clean the bores without going appreciably bigger.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
