KlotzBanshee Posted March 3, 2014 Report Posted March 3, 2014 I have a ported stock cylinder motor on a stock t&w crank and I think one of the rod bearings went along with a piston on one side. So what is my best option? Replace, Rebuild, Time to go 4 mill?? Quote
trickedcarbine Posted March 3, 2014 Report Posted March 3, 2014 4 mil! What type of port work is on the jugs now? Typically if it's not aggressive you can reconfigure stock stroke porting to work with a 4 mil. Quote
KlotzBanshee Posted March 3, 2014 Author Report Posted March 3, 2014 Fast Dune port. They need to be bored. At 64.75 now Quote
KlotzBanshee Posted March 4, 2014 Author Report Posted March 4, 2014 Oh, I didn't think you could go to a stroker crank with stock cylinders once they've been ported..? Quote
sheerider11 Posted March 4, 2014 Report Posted March 4, 2014 You usually can. Just call Jeff at fast and ask. There his work, he would know best. Quote
KlotzBanshee Posted March 4, 2014 Author Report Posted March 4, 2014 So is it really just not worth buying a new stock stroke crank and doing the top end? Quote
FullThrottle_06' Posted March 4, 2014 Report Posted March 4, 2014 So is it really just not worth buying a new stock stroke crank and doing the top end? You can do that if you like, but for the money your going to spend on a new stock stroke crank ($400 trued & welded, FAST Racing price) for $50 more you can go to a 4mill crank and gain a lot more power once you have your cylinders ported correctly for the added stroke.

sleeper06 Posted March 4, 2014 Report Posted March 4, 2014 You need to leakdown b4 teardown so u can rule out air leak for cause of problem , if it holds air proceed with tear down and inspection Quote
KlotzBanshee Posted March 4, 2014 Author Report Posted March 4, 2014 I did a leak down test and it held air all day. It was knocking like a mofo. Pulled it apart to find a scared up piston and cylinder on the right side. And I believe I found the culprit...there was a couple grains of sand in the right side main and pilot jets plugging them.

sleeper06 Posted March 5, 2014 Report Posted March 5, 2014 I would leave it ss my guess is it's too far for a 4 mill unless u want a drag port ,call Jeff for sure Quote
KlotzBanshee Posted March 15, 2014 Author Report Posted March 15, 2014 Ok, so I talked to Jeff and I am sending my cylinders in. He is going to see what can be done with them and If the transfers are too tall there may be a 4mil Serval in the future Quote
