Posted: Wed Sep 07, 2011 10:28 pm Post subject: WTS vortech v1 s-trim and short or longblock 347 stroker! |
|
|
coming out of a 94 mustang gt.
will sell the vortech v1 s-trim SC with 3.47 upper pulley,
bracket,
lower crank pulley.
38lb injectors
tb pipping
intake pipe with mafs and filter.
1600 for all sc stuff listed above.
347 stroker stock block 2 bolt main.
crower cam pn 15513
clevite 77 bearings
eagle rotating assm.
kb pistons
procomp heads valves 2.02 - 1.600
comp cam pushrods
10.5:1 Compression
CAUTION! motor has dropped compression in Cyl 3. troubleshooting went as far as adding oil into the cylinder and retesting compression, it raised 20PSI indicating worn rings most likely. this is as far as i have gone since motor is still in car. there is a possibility the cyl walls have been damaged and may need further repair than just rings.
will sell long block for 1600. or short block for 1000. price will change if it does not sell soon. im planning on pulling it and taking it to P&M to be torn down and rebuilt to sell as a fresh 347 long block.
please contact me at 910 934 9321
ps: also have a green 04 zx10r for sale! 6g obo!
fast bike! |

| yeah im not gonna openly badmouth anyone or start drama but ive talked to alot of professionals about how this could have happend and i have my opinions.... if you wana PM me id let you know all the details. but it all boils down to "if you wana play you gotta pay" im just fixing the motor and selling it, it would be great for someone that wants to stay N/A and maybe a small nitrous shot. the SC is overkill for this motor being a 2bolt main. |

once i get the block torn down and get a good look at the rings id be able to answer that better and throw names and companys under my hatful bus of bashing. i do have my own oppinions on it but i dont want to put them out here on this forum publicly without being 100% verifyed. im not ruling anything out though, i have my ideas but it could be from flimsy walmart rings my builder didnt tell me about or maybe wrong tolerances or assembaly imperfections... or it could have been the tune? you gusses is as good as mine without going into the block and seeing. 347's put a beating on rings due to the long stroke and the short length of the piston effects how the piston moves and can round off the corners of rings prematurly. it could very well have been a quality control failure when my block was assembled. now consider adding boost ontop of a small imperfection in the building process? we will just have to wait and see.
it might be worth my while just taking it to the machine shop to rebuild it. i would probably make more money off of selling it as a fresh rebuild with a local shop standing behind their work. but for someone who can tear these things down themselfs id let it go AS IS for cheap considering all the possible levels of damage.
if anyone is serious about taking this off my hands pre machine shop let me know asap if you want to hear it run in the car before i pull it out. |

| Are those 10.5:1 KB pistons Hypereutectic? |

| I'm his farther inlaw and we are not sure what type pistons are in it. I will say this, he has the dyno sheet and I have never seen a torque curve that looks like a heart beat! It was up and down the whole rpm range. The tuner said it was cause of the cam! We will not know the real reason till the motor is apart. |

| Just from outside looking in; IF those pistons are Hypereutectic and IF they are 10.5:1; I would not have been comfortable putting a blower on that motor. |

Yeah I was thinking this was the cause of failure too. 10.5:1 CR, hypereutectic pistons, boost, and pump gas is disaster waiting to happen. Even forged pistons with that kinda compression using pump gas can spell disaster. |

I think with forged pistons and pump gas; you'd have to run it on lower boost and keep the timing conservative; but still could be tricky if the pistons weren't forged from a good grade of aluminum. |

You'd be better off with 8.5:1 or something in that ballpark. Remember, the lower the compression, the higher the boost, the more powa you get! _________________

| That is true, but when the power curve looks like a heart beat and the tuner puts in the WRONG SIZE plugs( as in too short), that does not help things either. |

| What kinda power did it put down? Can you post the dyno sheet? |

347's aren't the most reliable motors on the face of the earth, a lot of people put them in cars for street driving because they put the power down and the simply wear out after a bit. I'm guilty of doing it. All in all they are best for straight up race. _________________
