I am a new comer to engine rebuilding. I am rebuilding a 264 engine in a 400 and i had a questions and i was told this is a good site to get answers from. I installed the crank shaft in the block, torgued the mains and everything and i could spin the crank with my hand freely. Now i have the pistons in and i have to use a wrench on the front of the crank to turn the motor. I was wondering if this is normall or if i did something wrong. I used a white grease assembly lube on everything. Thanks in advance

Farmall- I've used the white lubriplate assembly grease on small engines and it was fine. I use clean engine oil on the rings and cylinders. If all clearances are correct it is not a problem the engine is tight to turn over. Rebuilt a 350 Chevy that was very tight after assembly. That was 13 years ago and still running strong. Just remember to check all clearances and you will be ok.

I think you should've used engine oil on the pistons, sleeves and bearings. You could 've used
lubri-plate on the bearings too. I'm not sure about how much clearance you have on your bearings
using grease. A film of oil doesn't take up very
much clearance, somewhere around .001" to .0015."
The grease may keep your rings from seating too.
It's very important to have these parts well oiled during the initial startup.
Your oil pump needs to primed too in clean engine oil. Hal
PS: You should've posted here first.

The white grease i used was called lubriplate white grease assembly lube. I was wondering if this is the same stuff you are talking about or not. Thanks

It sounds like the same thing. Is there any writing on the container? This would be fine on the bearings. I never used it in cylinders or on pistons. I would pour some engine oil into each cylinder and crank over the engine so everything is coated with oil prior to starting the engine. Make sure you get oil pressure asap.
You can pump oil into the oil gallery where the oil gauge is installed using an electric pump using a clean 1/4" hose & a clean container of oil.
It will force oil throughout the engine and watch your oil pressure gauge for movement. Then your engine is prelubed. Hal

Increased friction from pistons, rings, and bearings will attribute to more resistance when turning the engine over after pistons are installed. It should have become a little harder to turn with the addition of each piston. If you checked piston ring end clearance and connecting rod clearance and both were good, then you should be fine.

Assuming you've properly pre-lubed everything, when you get it put together, leave the spark plugs out & spin the engine over with the starter until you get oil pressure. This makes sure the oil pump is primed prior to first starting the engine.

Engine assembly lube is fine for bearings, just coat the cylinders & pistons with oil when you assemble them.
