recently found a 350 that had been bored out .30 over, but the thing is that the heads warped and let coolant in the number seven cylinder. I was told i wound have to get it bored out again but with out pics can someone off the top of their heads tell me if i were need to get it bored back out again? ill add pics later on if needed

 

A hydrolyzed cylinder is as bad as a pc of steel inside the cylinder.If it leaked in faster than it could get out,it would be like that engine internals hitting a brick wall.Stopped dead in it's tracks.Have seen tweaked(twisted) rods,cranks bent,the whole host of possibilities.So beyond the needed boring,the rest needs to be checked and the block needs to be mag'ed to insure it was the heads that was the only problem.

If it is a question of purchase,I suggest you don't.

 

yea i was just checkin i was supposed to go check out a 350 but the guy was tellin me the history of the engine and what happened to it. well ill keep lookin i found some complete 350s for 500 to 550 and one thats rebuilt for 1200 bucks but if i did that minus well get it from summit or jegs

 

Best to pc together your own.Then you know for sure what parts are in it. Look for a 1996 to 2000 truck block and if possible a donor truck maybe low mileage crash victim.

 

the vortec motors? if so whats the difference between the actual blocks? I know the heads and intake are different

 

1pc RMS hydro roller blocks.

 

yea i just read in the tbi section the 305 to a 350 thread thats in the stickies. i would do it but on my local cl i dont see any vortec motors.just old sbc gen 1 blocks which some of them come complete and i want to rebuild from the bottom up anyways and can just get roller everything and a set of vortec heads but i want to get a hsr as an intake, only thing is, is that i need to get a tpi harness

 

Here's the 355 that had some coolant in cylinder number four

 

Another pic phone is actin up

 

block looks to have a crack in the deck into the number 5 cylinder... keep looking you will see it

 

ok my mistake number five cylinder is the one that had coolant go into it, i felt it it was rough. he said it would need to be honed out or just bored out again. for fifty bucks tho thats seems to be a hell of a deal.. He's also got some L98 corvette alumiun heads for sale, i may just buy the heads if i get told by enough ppl that the block is a no go..

 

would suggest passing on any head this guy could have had bolted to that block...

the crack if that is what it is... is clearly visible and the only reason to even try to sell it is to give someone the screwin'... 50$ is one of the too good to be true even if it didnt have a mystery catastrophic failure

 

yea I gotcha man thanks. the heads are from another engine from what he told me he hasn't givin me a price yet but ill take pics and inspect those carefully if I decide I want them. well for now ima keep lookin for another engine

 

so i found a 350 its been rebuilt the guy put new crank pistons and the heads are 462624 casting numbers. doesnt come with the pulleys or flywheel/flexplate, intake either, which is fine with me..he wants four hundred for it so im goin for it. once i get it i wont start workin on it til next month or half, ima gonna save up more money and go to town on it. once i get this engine ima find out what all my options are. i know for sure i want to do a hsr but if not then a holly tbi unit
