78 Ford Thunderbird w/ 351 Windsor motor

How were the rod bearings? I always check them whenever replacing the main bearings. Why did you only say "main bearing"? There are always more than one.

could also be part of the fuel pump dropping do into the oil pan is now hitting the crank, but you checked the oil pan for "bits and pieces" when you took it off to change the main bearing - right?

The 351 cu in (5.8 L) Windsor...




Hope this helps (remember to rate and comment this answer).

you will have to raise the engine so you can get the oil pan off

not too much work,the motor mounts-bell housing and crankshaft (for the flywheel off the 302)all should be the same.if the 351 had an automatic transmission,then you will have to add a pilot bearing to the end of the crank (center of crank where flywheel bolts on)..Also it depends on which oil pan is on the new engine--to follow the curve of the frame but should be the same as a 302....302 and 351 windsor engines are the same block except the intake manifold.Just a reminder,truck engines have a better cam for more torque.If the truck is fuel injected you will also have to change the computer which would be located drivers side left upper kick panel.The exhaust manifolds may be different,check them out before starting the procedure.

The only 351 Windsor with solid lifters is the 351 "R" 4V
1971-1972 Boss 351-HO. All others are hydraulic. To solve noise in hydraulic lifters, replace them and check push rod ends for wear (actually you really should change them, too) but many guys go "cheap charlie" on this.

port polish only on heads, they crack plus valve job. on the block and cam, that motors all torque so go with low end output, fat cam, 30 over max on bore-they crack. safest way for big power is a stroke kit. call edelbrock tell them you wishes and what you have now, main thing is how much your gonna have to bore to clean up walls, and they give you some good options. unless you have alota money and dont require this motor to be dependable dont expect more than 320hp and 350 ft of torque. 302 will take you farther cheaper and lighter for your money. if your talking for a car and not a truck- go 302 and dont look back

No you done have to drop any thing, you just need a new oil pan and gasket for it, loose all bolts around the oil pan and you should be able to remove it, remember remove all the broken off of the old gasket very well before you apply a new one on with grease or gasket cilicon stuff then new oil pan, good luck.

If it is a factory car pan 5qts,
Drain pan, add 5qts, run 5min check oil.
