What is the ideal crankshaft clearance for a chevy motor on the mains and rod bearings? I am going to tear down my lower end and check the clearance on the rods and mains...........I have a feeling it will not be right :banghead:

PLastigauge is just a quick check, I'd say about .003 should work

I hate to say it, but this just doesn't make much sense. Complete the engine you have and get it in the boat. Use it to "shake down" this new-to-you boat and work all the bugs out, while at the same time enjoying a summer of boating. It will also give you a chance to see if the boat needs more power or if it can even safely handle it. You can start collecting parts for a bigger engine as cash flow provides. I've seen too many people fall into the trap of making plans for bigger, better, faster, only to end up selling a never completed project.

Again, finish what you have now and get out and enjoy the water!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

That would involve making sense OldSquirt   ;D . Seriously , finish it up and just enjoy being on the water . When is enough , enough ? It never is , you'll just be chasing your tail for the rest of your life . Pick someone to advise you on how to put your motor together and stick to his regiment . When you focus in on your goal it'll be done in no time . Good luck and I really hope to see you on the water soon .

I've got an Edelbrock Performer RPM cam/ Missing 1 lifter used a couple seasons. It's has a 565/ 570 lift and I'll be in Havasu on the 17th. If it will work for you and you pick up in Havasu its yours for free.Thats if you finish this damn motor and get that boat in the water this season. Ron
