393 update

Ran into a small issue during the dummy fit. Whomever rebuilt the block when doing the 20thou over build screwed up.

Normally during a 393 build the pistons stick out of the bore 5 thou. One side of mine is stick out 5 thou and the other side sticks out 15 thou.

The blocks being decked to square and the pistons are having 15 thou machined off the crowns. Just as well, I have a piston with a 10cc dish

Least I probably won't have to deck the heads Camshaft choice has also changed as a smaller one made more torque.

Hopefully I can get it back this week and screw what I need to screw together ready for the engine dyno.

Re: 393 update

Must have decked the block after their lunch break. Whats the best way to check deck height? Do you need the crank rods & pistons installed?

Re: 393 update

Good thing you checked and measured. Good one Brenx!

There's a valuable lesson there for amateurs like me.
I need to get the correct measuring tools.

brenx said that who ever built the previous 20th over motor made a hash of the block, and has been discovered during the dummy assemble, by either Pavtek or brenx. Thats what the dummy assembly is for
Does the machining of the pistons affect balance brenx, or is it all good?

Re: 393 update

Machining the pistons will affect the balance and will need to be corrected accordingly. Hopefully I'll have the engine back here this week or early next. Hopefully no more little issues will be encountered.

I'd kill to know who did the 20thou over build. They are definately stooges. [edit] I know the 20thou over build was done in either TAS or SA

Re: 393 update

I wonder if a variation of 10 though from bank to bank would have been evident on the previous build? Would it idle rougher or always have a slight vibration?
