The main concern being with a combination of all these things it may be possible that the piston spends a little more time dwelling at top dead center (whilst the cam's keep turning and smash the valves into the piston top). In reality with correct valve timing and if the pistons aren't dome tops it's pretty safe (especially with standard cams). Also need to consider piston to deck clearance (can easily be measured). IMO anyone who has ever done any machine work and rebuilt a motor should be able to do it for you (if the head is assembled it's possible even to measure it and allow for thermal expansion, and then do one dummy assembly with the plasticine fro reassurance). The other thing is figuring out the dummy cam to keep the oil system going. Pretty straight forward stuff for an engine builder though. You could always email toysport for more info. I think you should at least have a chat to or email the guys at pavtek as well if you haven't already. They do jap motors as well as v8s, aren't insanely expensive, and aren't dead shits that have only ever rebuilt a holden red motor. my 2c [Report message to a moderator]
