well i picked the car up yesterday... it drives like an absolute dream.. drives like a stock car. i noticed on the way home what the tuner was talking about... i worked on it a little this morning, i found some really loose clamps on the charge pipes so i tightened them and i also changed out my cam sensor wire as it was all spliced up and nasty.... took it for a ride and what do you know it drives mint!!!! finally, just need to get it back on the dyno so the tune can be finalized and ill be able to finally enjoy the car...
the car drives absolutely amazing. the valve train is no louder then a stock car, idles mint, cold start perfect, just so happy with how the car has turned out.

few vids
cold start, it takes a second to turn over, i forgot to let the fuel system prime before turning it over.... once it warms up and drops idle its so quiet. love it

Woohoo! Time for a nice license plate

StealthFRC

yea man, I'm so happy it was something simple. just the to schedule another day for the rollers and ill be good. can't wait to just enjoy this dam car....

StealthFRC

well guys i brought it to the dyno yesterday for some final tuning. had the car running absolutely perfect, made one pull on 13psi and all was good, turn it up... hit 18psi and about 4400rpm and just hear a very loud pop... try to start the car, turns over like no compression. pull the oil cap, motor turns but rockers do not move... guess we snapped the timing chain. this blows it was a brand new cloyes double roller. ill know more in the next month or so, i left it at the shop, I'm done working on it... i just do not have the time anymore. the engine builder is willing to help out which is nice, we will see where it goes and if anything is salvageable... if there isn't I'm not sure what ill be doing.

sorry to hear john..
I would be looking into harmonics..thats a brand new double roller something had to make that break

StealthFRC

I think it's just parts failure. The cloyes makes the chain tight and takes all the slack out, I think it just got to tight. We will see when everything is pulled, is what it is at this point.

slow ride

So sorry to hear. You just can't catch a break. I wouldn't **** with a double at all. Katech c5r with new stock gears and a ls2 style guide. Make sure the balancer is quality also.

blown81bu

..this guy right on..its what I use

StealthFRC

Yup, I've already been told what I should do with the new setup. C5r is on the top of the list. We will see what it needs when it's opened up, depending what it is will decide if I stick with the ls2 or go a different route.

I'm also going to get those short travel lifters out and go back to ls7's but this is all the Lear of my worries at this point

Man, really sorry to hear about your motor. GL with the next setup, I really hope it works out for you soon.

ajrothm

That sux man, sorry to hear this. Your luck is as bad as mine.

I hope the damage is minimal.... I wonder if the chain failure is somehow related to when you had the valvetrain issues with the long push rods etc etc...? I couldn't imagine a double roller chain just breaking for no reason. HMMM..

I know how bad you feel right now...You're not alone. We should start a therapy group like AA for C5 owners with constant failures...LOL

lsxvette

wow thats **** news just had a friend break a chain also ,blows, they traced it to a powerbond and broken oilpump gear

StealthFRC

yea, we won't know till its pulled. its going to be a few weeks until then. the shop is very busy and this obviously wasn't scheduled. they are doing me a huge favor by taking on the job, i just have 0 time now.
just doesn't make sense, the car was running great... no noises nothing ran mint. everything was spot on....
the car has a IW balancer. guess we will find out when its opened up.

StealthFRC

Well got some "good" news. Turbos are unharmed which is good.
At this point I'm very close to just having a new engine built. I'm leaning towards a sleeved ls3 427.
I'd have that built on the side and let the builder of my current engine take care of it then just sell it and cut my losses.

Decisions decisons.
I'm just curious what people's thoughts are with the larger engine and there turbos?
I'd like more off boost power etc.

slow ride

It depends on the old parts condition. I'm so cheap I'd patch it up and run it but that's me. Let us know the condition of the heads and Pistons etc

StealthFRC

Regardless of like to order a whole new engine and not reuse anything, have the current one fixed and just sell it. I have a friend that would buy it for his Camaro.

StealthFRC

Would get done faster aswel

slow ride

Well I'm not sure about which one would make more peak power unless it's octane limited. The larger engine is going to feel thicker everywhere. Hell my 383 feels solid but I run e85. Either way a sleeved block will have stronger and longer liners to better support the piston at BDC.

Blackonblacksls

Don't build an engine that big when turbo limited. Just do a stock stroke deal.

Just my opinion.

StealthFRC

my current engine is stock stroke and its never made the power i expected... its also a turd off boost.
i think the 6265's would be fine with a 427... I'm not after ever last bit of HP nor am i after peak numbers. I'm to the point that if I'm going to build another engine im going all out.
if my current engine can be fixed i already have a buyer for it.
