Title: cv20s questions
Post by: westcoast racer on March 01, 2014, 06:42:43 pm

What are the weak links of these engines?  What kinds of modifications need to be done to this engine besides billet flywheel?  Can they be bored out 0.240 which is the next piston size? Does the carb need to be changed if that is done?

What are you wanting to do?    My guy can hook you up with what ever you want.   Call Zach Kerber machine.  1 (712) 566-3008.  That is the shop phone.   He has flywheels And all the parts you need from mild to wild. 


I've been testing a vertical for him in 2 different stages.   This year we are testing a "budget" engine.    It made 50 HP then the belt on the dyno exploded.   I can't remember the price of the kit. 

He is out of town this weekend.   I'd call him Tuesday or later.
