sleeving a block

[jimmycarter]

does anyone know about how much it would cost to sleeve every cylinder of a 340? i took mine out before it was extremely weak. i havent taken the heads off yet, so i dont know if its cylinder wear, or a ring problem

[5th_Ave_Sleeper]

My machine shop charges $80 per sleeve+ the cost of the sleeve @$10-15 ouch!

[jimmycarter]

ouch is correct

SOUNDS ABOUT RIGHT MY MACHINIST CHARGER ME 75 BUCKS GOOD THING IT WHAS JUST ONE. 80X8=640+120=TOO MUCH FOR ME YOURE BETTER OFF LOOKING FOR ANOTHER BLOCK.

i figured if it was less than 50 a piece i would go ahead and do it. if im not able to rebuild it without sleeving, i think i'll just keep it in my garage. maybe some day i will stumble upon a bag of money

[John Kunkel]

I wonder why, without disassembling it, you would worry about sleeving. Was it bored to maximum before?

[jimmycarter]

its on an engine lift, via head bolts, and i dont have anywhere to put it right now. im trying to figure out of i should start saving money to rebuild my block, or just go ahead and buy a suspension rebuild package.

You could sell the 340 to me!

Don't panic about sleeveing until you get it apart.

It shouldn't need to be sleeved, unless it's been rebuilt once already, and then worn out again. Even then, if it was a factory reman, they are only .020" over, and pistons are available up to .060" over.

i was just thinking of all the possibilities as i sat down and tried to figure out everything i would eventually need. i suspect that its been rebuilt once. the intake manifold has obviously been off, non factory freeze plugs, and the paint looks to be about 5-10 years old. hopefully it was only .10 or .20, id rather not have to bore it out to .60 over. ive got a 360 that im about to put in the car.

what i was thinking about was rebuilding the suspension while the engine was out so i dont have to undo the transmission bolts again. i have big fat hands, and that was a pain in the ass. but if the $300 would be better spent on getting sleeves, i didnt want to spend it before i knew.

i've got my 340 bored .040 over, it had been rebuilt once before but not up to my specs.... go to http://tmezz.mezzweb.com/ to look at it. i would keep a 340, with the right combo you can run mid to high 10's with me! (don't freak, i've got my hopes up because according to about 3 people and some stop watches on a road with mile markers in 1/4 mile increments thats what i run...)

i would rather bore it, than to sleeve it unless you don't want bigger pistons....bigger pistons is more cubes....a little more power...

I'D think twice about boring a 340 out to .o60 that is a little thin for that block and might calapse :

[1972roadrunner]

well, .060 at 12.5:1 compression would be scary, but if your just runnin a stock, daily driver, 10:1 compression could work, but still a little scary

[jimmycarter]

i wouldnt want to bore 60 over either; unless the block was sonic checked. i noticed in my book that it says +.40 maximum.

that is a nice looking roadrunner, by the way. im drawn to the work in progress/mad max 2 type cars. for some reason they appeal to me more than a bright shiney 100% restored car.

Mother says MOST SB pre 77 blocks can be bored .060". I have checked the core shift on my 340 and I wouldn't hesitate to bore it 60 if I needed it. My 340 has about 175,000 on it and it mikes out a .017" wear so I will have it bored .030 to make sure it cleans up properly. The 340 blocks have a high nickel content and don't wear as quickly as a standard performance block. I'd have the block checked for wear by a good machine shop and make my decision from there. The one constant you can count on is that if you cut corners you will have a cut rate engine. If you can't afford to build it right the first time, you can't afford to build it twice or three or even four times. If your in a hurry, you should rethink your plans. If you do it right you will understand from the performance and when you hear others complain about all the problems they are having.

thanx jimmy, i too like the more rugged, faster cars than the 105% restored trailer queens driven by sniveling little creeps that don't want you checkin out the engine for fear you'll get it greasy or think about stealin sumthin.....

i like bein able to make mods and not worry about price, i'm not plannin on selling my car for a VERY long time!
