WAY2MANYTOYZ Posted September 19, 2015 Report Share Posted September 19, 2015 I'm looking to get a pro mod tranny done while I have the cases split for a new crank. I spoke to Jeff at FAST today about it while I was ordering a new crank and plan on sending him my trans next week to get cut. I've done quite a bit of searching these forums but I can't seem to find anyone who has had one cut from him, all I find are great reviews on camatv and redline. I'm sure if I get it done from FAST it will be great as I have always had top notch service from Jeff but it would really help me to hear a few positive reviews (or negative ones but hopefully not) before I pull the trigger. Can anyone help me out? Thanks Here is my crank now... I know how you guys like to see carnage! Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
WAY2MANYTOYZ Posted September 19, 2015 Author Report Share Posted September 19, 2015 I'm still puzzled by the bent rod? The top end is still almost perfect. Just a tiny ball point pin sized ding in the dome and a very light scratch on the cylinder wall from a piece of bearing that made it up there. No sign of heavy enough contact to bend the rod...

WAY2MANYTOYZ Posted September 19, 2015 Author Report Share Posted September 19, 2015 That's the only thing I could think of too as it reminds of PWC rod failures from getting submerged or rolling over the wrong way but where could the water have come from? Radiator and res were still full and I had been riding it all day before it happened. I was WFO in 6th when it failed and shut it down immediately. Spark plug looked to be firing at time of failure too. Is it possible the main jet could have worked loose and took a surge of fuel in? I'll have to check the carbs on Monday...

trickedcarbine Posted September 19, 2015 Report Share Posted September 19, 2015 Plugs wet and greyish? Cyls have aluminum in the bores? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
registered user Posted September 19, 2015 Report Share Posted September 19, 2015 if theres no foriegn material indentations in the head or piston top then you can forget that idea. main jet falling out would only cause the engine to run like a turd. gas engines have a low tolerance of being over fueled, you would know right away if it fell out. the rod may have simply been stressed to far, especially if you had big ass heavy pistons. the rod has to deal with alot more push pull forces than people realise Quote Link to comment Share on other sites More sharing options...
WAY2MANYTOYZ Posted September 19, 2015 Author Report Share Posted September 19, 2015 The one plug was slightly grayish but the other looked great. Bores and pistons still look great no aluminum or visual wear at all. Just a very small light scratch from a bearing piece passing. Wish I had more pics. I'll post some Monday when I'm back at shop.

I wouldn't think they could bend a hot rods crank... Quote Link to comment Share on other sites More sharing options...

WAY2MANYTOYZ Posted September 19, 2015 Author Report Share Posted September 19, 2015 How many hours??It's hard to say how many hours on the bottom end as I bought it used but I would say it is on the higher end for the life of a crank. The left side thrust bearings were looking pretty thin as well so it was probably just its time to go. I was still shocked to see the damage as I figured it would just be a slightly leaned piston. I am really thankful it didn't fully grenade. And before it comes up, I did leakdown test it before tearing it down and it held 6psi for over 30 minutes.
