    I can get a complete long block for $635 with all cast stuff. Well, my question is, after they torque down the main and rod caps, can you undo them without messing up the bearings? I found a set of Hyperteutic flat top pistons for $101 and I was thinking that I could get the pistons, take out the rods and get the new pistons put on, and then re-assemble it. Can I do this???

    My two cents worth would be why bother ? First off do you really need Hyper. Pistons? If this motor is just gonna be a mild buildup then I would say just keep the stock stuff, otherwise if you really want the better pistions then get them and just get a 350 block done up as it will be much less of a hassle IMO.

    Yes you can do that but if you'r not using the motor for racing or even street drag racing then it would be a waste. Your $635 long block will most likely withstand anything you could give it short of racing.

    I think adding flat top pistons for a little more compression would be a good idea, but cheapy cast ones will work just fine.

    City Motor Supply in Dallas and San Antonio. $635 is a complete motor from the basics to the rockers and a gasket set. Even comes with some Blue Silicon and engine paint. Website is www.citymotorsupply.com I forgot to mention, the pistons that are stock are dished cast pistons, the ones I want to put it are Flat Top 4-valve relief Hypereutectic with anti-friction coating from Federal Mogul.

    Most places like that have different options for their motors. You also might want to see if you could just have them install the flat top pistons to start with insted of breaking the engine apart after they just put it together.
