Banshee2105 Posted December 23, 2017 Report Share Posted December 23, 2017 So I'm pretty sure this crank that I got for this motor is a stroker crank and that's the issue here. I'm trying to do an all stock setup. I need to know how to fix this ASAP. I have a trip coming up and I *really* don't want to tear this engine back down. Is there anything I can do? Of course if I have to I will tear then engine down and replace the crank. This crank is welded. If it comes down to it, anyone game to trade for a stock crank? Thanks guys!

gusto Posted December 23, 2017 Report Share Posted December 23, 2017 Well quick fix assuming you know the stroke of crank is to have the domes cut. do you have the packaging the crank came in? Quote Link to comment Share on other sites More sharing options...
JUSTWANNARACE Posted December 23, 2017 Report Share Posted December 23, 2017 If I was to guess it is a long rod crank and you need 795 long rod pistons. To stick out that far with the correct pistons it would have to be a 10mm stroke or bigger. Cause a 7mm stroke with 115mm rods and 795 pistons the ring will not come out of the cyl. A 10mm stroke with a 795 piston the rings will come our of the cyl.. Quote Link to comment Share on other sites More sharing options...
JUSTWANNARACE Posted December 23, 2017 Report Share Posted December 23, 2017 Do you have any pics of the crank before it was installed? Quote Link to comment Share on other sites More sharing options...

JUSTWANNARACE Posted December 23, 2017 Report Share Posted December 23, 2017 There is no "quick fix" with what you have going on there. You will need to figure out the crank and rods so you know what you have and what pistons you need. Quote Link to comment Share on other sites More sharing options...
JUSTWANNARACE Posted December 23, 2017 Report Share Posted December 23, 2017 If you can measure the the total distance of the piston pop out at TDC then we can probably point you in the right direction Quote Link to comment Share on other sites More sharing options...
gusto Posted December 23, 2017 Report Share Posted December 23, 2017 Could also be wrong pistons Quote Link to comment Share on other sites More sharing options...
JUSTWANNARACE Posted December 23, 2017 Report Share Posted December 23, 2017 If it's a stock stroke long rod with stock style pistons it's going to stick out 5mm.. if it's a 4mm long rod with stock style pistons it's going to stick out 7mm ect..

So I just measured and at TDC the piston is sticking out 5mm. What is the fix for this? Edited December 24, 2017 by Banshee2105 Typo Quote Link to comment Share on other sites More sharing options...
JUSTWANNARACE Posted December 24, 2017 Report Share Posted December 24, 2017 Swap the piston out for wiesco 795 series long rod pistons Quote Link to comment Share on other sites More sharing options...

Rigid_Banshee Posted December 24, 2017 Report Share Posted December 24, 2017 Are those cylinders brand new oem, Niche, or used ? Just wondering the new looking paint caught my attention. Quote Link to comment Share on other sites More sharing options...
