The shop I got the 355SB chevy engine from had the engine built buy a pro.

They set the rockers. buy snugging them all down. Does that sound right to you? then they went threw the order and pre loaded the hydrualic tappets 3/4 turn.

The fuel pump they still say is fine. puts out 10psi fuel pressure.

The coke wire for the electric choke is only putting out 1 volt. when it is connected.

The engine ran bad after breaking in the cam. yes I primed the engine.

The engine lasted 62km/38.5miles.

The engine siezed 8km short of makeing it back to the shop I bought the engine from. they were going to take a look at it.

So, the cam and lifters ae very likely shot, the engine needed new barings, piston rings, honed and the crank at least poslished.

Plus the choke is set wrong on the carb I got rebuilt.
