hate to hear that,hopefully your car will be back on the road soon,aint nothing like a new LS1 engine although a LS6 doesnt sound like a bad idea

then im changing my opinion lol 3400-3600 stall, with a bolt on ls1 and some decent tires high 11's are there

**jiveass** · 04-20-2011, 07:47 PM

im wonderin how much i can make with port and polish on stock heads...or perhaps some massaged 243's

**redbird555** · 04-20-2011, 08:47 PM

honestly if your going to go with some worked heads and maybe a small cam a crate motor may not be the best way to go. with a stock cam the max you would probably see with heads is 20-25 hp just because the cam isnt big enough to take advantage of the heads. I personally like this build l92 heads on an lq9/ls2 engine of your choice... Get an lq9 shortblock $1200 new slap a set of $700 new stock l92 heads add an ls3 intake and a cam spec'd by pat g and make these numbers for under $3500 cant really beat it. the price it would cost to do this with cathedral heads and an ls1 motor would easily exceed 5k....(link is to ls1tech please do not remove its just a dyno graph) http://www.ls1tech.com/forums/dynamo...p-446rwtq.html

wello it has been confirmed.....i have a bad bearing....time to remove engine. damn....

**BashamWS6** · 04-23-2011, 09:29 PM

Ha i just had mine confirmed today. Spun bearings sound great!!

**98maro** · 04-23-2011, 11:36 PM

so what are your plans??? stock? stroker kit? mine is almost gone too

**jiveass** · 04-24-2011, 12:03 AM

i havnt decided what to do yet...i think the easiest thing to do is to replace the bearings and if necessary get the crank machined

unless the crank is really chewed up, chances are you can simply polish it and check that it's still within clearance tolerance and won't need to run oversized bearings.

**BashamWS6** · 04-24-2011, 12:11 PM

im thinking ls6

or inanything... ill get a ls1 crate and just get a 408 when this isnt my DD

By your track record, you'll still be thinking that 10 years from now...

The pistons may or may not need to be replaced but they usually come with a master rebuild kit. If that motor did spin a bearing there maybe ,metal fragments in the oil passages that would recirculate into the rotating assembly when its put back together so a hot tank wouldnt be a bad idea. IMO if the motor has 100k on it would dumb not do a total rebuild just because it looks ok doesnt mean its not worn. I suppose it could be done for 500 bucks but it would kinda be a low cut job....

We always get in the discussisions on here I never see measurements posted, I.E. cylinder out of round. ring end gap. main and rod clearances cam measurements. deck flat. NOTHING. Just speculation at how long an engine lasts.

I have swapped plenty of bearings just to quiet an engine down with no problems.

+1 hell yeah, just clean any obstructions with some mothers, and measure that bitch.

shit...i beat the hell outta this engine...thats what its made for....if a rod bearing is the only problem i got then im fine with that.

I have also and they all are running fine to this day. However with this being a high performance motor I would want to make sure everything is good. I'm not saying the cylinders will look like eggs and yes you could probably get away with the original pistons but heres my reasoning why I wouldnt in this case. These motors have piston slap already (usually) in that case honing the cylinder and then just doing a re-ring doesnt help the problem. For the 1k your going too spend on a complete rebuild kit ie all new bearings, rings, lifters etc the kits come with new pistons of your size choice. In this case why not use them? Have a machine shop bore the block .010 and ensure a good tight fit. Once again not saying its necessary but if my motor slapped it wouldnt even be a question if it was dead quiet I would probably just clean up the bore and put all new rings/bearing etc. No way in hell i'd be putting the original rings and cam bearings back in there.

**Jay37** · 04-26-2011, 07:45 AM

I see your point. I feel that a factory short block is very safe up to 450hp so IF IT IS WITHIN THE FACTORY SPECS, I don't see a need to change anything. I also don't consider piston slap a problem, although it is a hit topic on this site.
