** NOTE: Chevy 350 (1968 through 1999)

1. Do not over-torque flywheel bolts. Bolts must be torqued to 75 lbs, or you will warp the crankshaft seal surface and cause a rear main seal leak.

2. Do not over torque oil pumps when mounting them to the rear main cap. Oil pumps must be torqued at 65 lbs, or you will pull the rear main cap out of alignment and cause main bearing damage.

3. Oil consumption will occur if the intake manifold, if not torqued properly. Start by torquing the two middle bolts and working your way out, by torquing one side, and then the other, until reaching the ends. This will work out any reasonable warp in the manifold, insuring a proper intake gasket seal. If there is an intake leak. it will suck oil from the lifter valley and/or suck air in from the outside, causing a lean burn condition.

4. Exhaust manifolds get very hot over years of use and will spring out of shape when removed from the old engine. When you try to install the exhaust manifolds on the new engine,  they will not fit, the last bolt hole on the manifold will not align with the cylinder heads. When this happens, a torch must be used to heat the manifold and expand it, then while its still hot, align it to the exhaust ports of the cylinder head and bolt it in place.

5. All General Motors oil pumps are fitted with a pick-up screen, that must be pressed into the oil pump. Many times this pick-up screen is not properly fitted into the oil pump and will fall off after a short time of use. Care must be taken to ensure the pick-up screen is fully engaged into the oil pump and then finally solder the pick-up screen to the oil pump. Care must also be taken to make sure it is adjusted to within one half of an inch from the bottom of the oil pan. It is never recommended to use an old pick-up screen from your old oil pump, a new one must be used.

6. Make sure the oil filter you install, has an anti-drain back on it.  If you don't, every time you stop your engine, all the oil in the engine will drain back to the oil pan and the next time you start it, it will dry-start. Over a short period of time,  all the dry starts will damage the engine bearings.

7. Never,  Never,  Never!, use an abrasive disk to remove old gaskets from your engine. The abrasive disk will dislodge aluminum oxide from the discs - the abrasive material its made of - and this will contaminate your engine. It will get into places you can't clean and the abrasive material will mix with the oil and destroy the engine. 

8. Never use the old EGR valve from the old engine, always replace the EGR valve. If the EGR valve is not working, the combustion chamber temperatures will increase by as much as 2,000 degrees, causing piston failure.

9. Always replace the 02 or anti knock sensor, when doing an engine change. These sensors are vital to the new engine’s computers.

10. Engines with aluminum intake manifolds, must have the anti-freeze changed every two years. The anti-freeze has a chemical that stops electrolyses from eroding the aluminum manifold, after two years,  the chemical that stops electrolyses is spent.

11. Engines equipped with oil coolers have extremely small oil passages in the cooler that make up the element. This design makes it necessary to replace the oil cooler after bearing failures, or any catastrophic engine failure that produces debris inside the engine. Remains from a failure become trapped inside the oil cooler and cannot be removed by degreasing or flushing the cooler. Trapped particles are likely to re-enter the remanufactured engine's lubricating oil supply,  causing a repeated failure.
