crank question

[wooten]

i recently bought a 02 with a 400 long rod stroker kit in it or thats what they told me and the dumb asses ran straight gas through it and it ate one of the crank bearings up!!! i was just wondering if you guys could lead me in the right direction of who could fix this i now have a new stock crank and rods and ultra lights but need to get the stroker going again

you have to watch, people say stroker, but is really only a long rod crank.a long rod is not a stroker.call andy 1 616 642 6186. he can rebuild a crank.

how would you go about finding out if it is indeed a stroker

[wooten]

the case had notches in it , how much does this usually run to get that fixed, and what kind of pistons would i have to get for that

[NYUK]

case was gouged? i would let a builder look at it to see exactly what you have and if it repairable. gouged cases under the crank does not mean the cases are no good,i have broken pistons and still used my cases. long rod cranks usually run blaster pistons .

Or wiseco 795 series pistons. If its indeed a stroker you'll have either multiple cylinder base gaskets, a spacer plate, or if you don't turn the engine until one of the pistons is at TDC, it will extend 2mm (on a +4 stroker) out the top of the cylinder. Alternatively, you could measure the total stroke. Stock stroke is 54mm so a +4 would be 58mm, +7 is 61mm, etc.

it wasnt from the rods or anything it looks like it has been notched by someone i am running it now with no problems where is andy located and is this worth the trouble trying to get it fixed and the money i mean is it going to help it that much

If the cases look like they were "notched" by someone, and it looks like good clean machine work, it was done to enable clearance for a 7mm stroker crank or bigger.

If yours isn't a big stroker crank, at one time those cases were home to one.

I'm a dumb newb.What is the difference between a long rod and a stroker??My buddy has a long rod crank he wants to give me and i'd like to know what it does for performance if anything.Not to highjack this thread or nothing.I'm just curious.

[banshee04le]

Torque is what gets you down the track. Take a torque wrench for example. Set it for 100 ft lbs...if you choke up on the handle you might not be able to hit the torque mark but if you get out on the end of the handle you have more leverage and it is easy.

A stroker crank has the crank pin located at a point of greater leverage.

A stock stroke 115mm long rod crank has no torque advantage over a 110mm

short rod crank (stock). On strokers that are larger than 4mm, a long rod increases reliability by decreasing the maximum rod angle which causes piston and bore wear due to angular force. The increased reliability of a long rod is less of a factor on stock stroke and 4mm's because the rod angle is not that excessive. More stroke = more rod angle..

[Wallrat]

Exactly. But a tad confusing don't ya think? Just remember:

stroker=more power

long rod=more reliability.

Banshee04 your the man,but damn you lost me lol.Thanks Wallrat for saying it in ebonics terms lol.

[wooten]

well it is indeed a clean cut not from anything hitting it, but i need to just try to maybe get the numbers off of it and try to talk to the guy that had it put together and see where he got it thanks for all the help

[wooten]

i hate to keep asking so damn much but would you know the length on this and is there any way that ya know to look these numbers up to try to match them????
