Jamesboyz banshee Posted March 31, 2014 Report Posted March 31, 2014 Okay I need some input on this because im hearing alot of different things. So I was planning to go from a 4mil cub, 68mm to a 10mil. I know to do it I need my cases trenched & a new crank. But my question is do I need a spacer plate so the port timing will match up? What do you guys think about it? Any input will help. Thanks! Sent from my SCH-I535 using Tapatalk Quote

m671054 Posted March 31, 2014 Report Posted March 31, 2014 It might be possible. ive had a 4mill cheetah that we turned into a 10mill. it used non normal parts and had lots of machine work done. look on cp webstie and compare dimensions from a 4-10 cylinder. pay attention to overall cyl height first.

RadarRacing Posted March 31, 2014 Report Posted March 31, 2014 ^^ I am with these guys. Stick with the 4 mil or start over. You wil be out maybe what $400-600 by selling your 421 used and getting a new 10 mil cyl. Honestly if you think it runs well now it will only run worse. If it runs like ass then maybe someone can fix it into a half assed 10 mil for ya. Not hatin , just answering your question. Quote
Jamesboyz banshee Posted March 31, 2014 Author Report Posted March 31, 2014 Thanks I didnt say I was gonna do it. I just wanted to know what other people thought. Didn't know I would almost get killed for asking haha. Sent from my SCH-I535 using Tapatalk Quote
Jamesboyz banshee Posted March 31, 2014 Author Report Posted March 31, 2014 Well you hear something new everyday. I won't saying that's all you had to do because if that was the case everybody would have one. I read something about somebody using a spacer plate. Just wanted to know what it was all about.

bluebanshee98 Posted March 31, 2014 Report Posted March 31, 2014 Do it right. Send to a good builder . I recommend Redline. He could sell your old cylinders to fund the new build and have him do the engine. You'll love a 10cub Quote
Larry's Shee Posted March 31, 2014 Report Posted March 31, 2014 The porting alone would probly be the deal breaker, especially if you fubared the plating. Quote
RagunCajun Posted March 31, 2014 Report Posted March 31, 2014 do yourself a favor and stick with what you got if your asking why OP if post like that bothers you, get with a forum sponsor and they will help you. They helped me go from 4mil to 10mil and didnt know all the technical stuff off hand. Quote
