Thread: Question About My Fe 360?

Tweet

CAN ANYBODY GIVE ME SOME HELP FIGUREING OUT WHAT i'VE GOT . I BOUGHT WHAT I THOUGHT WAS A 390. i TOOK THE GUYS WORD FOR IT AND SENT IT OFF TO BE BORED. iT HAD TO BE BORED TO 4.11. WHEN IT CAME BACK I CHECKED THE STROKE THE STROKE IS 3.50. WHEN I CACULATE THIS OUT I COME UP WITH 372 CUBIC INCHES. WHILE THE ENGINE WAS OUT BEING BORED I ORDERED .060 OVER 390 PISTONS. i HAD THE PISTONS MOUNTED OD THE RECONDITIONED RODS THAT CAME WITH THE ENGINE. AFTER IT IS ALL INSALLED THE PISTONS DON'T COMPLEATELY COME UP FLUSH WITH THE YOP OF THEENGINE DECK.
I THINK WHAT I HAVE IS A 360 TRUCK ENGINE BORED .060 WITH 390 PISTIONS. THE ENGINE SHORT BLOCK IS ALREADY ASSEMBLED AND IF IT WILL RUN THIS WAY I'M GOING TO USE IT. IF NOT I HAVE A 1963 390 WITH FOUR BARRELL INTAKE OUT OF A 63 1/2 GALAXIE. CAN I SWAP THE CRANK OUT OF IT TO THE 360 WITH OUT CHANGING THE RODS?
THIS IS MY FIRST FE ENGINE. I NORMALLY DEAL WITH 385 SERIES MOTORS.
I ALSO HAVE A CRUISEMATIC TRANSMISSION OUT OF THE 63 GALAXIE. IS IT ANY GOOD?

How far down are the pistons? A 360 uses 390 pistons with longer rods. A 352 is .050 smaller bore, with shorter compression height. If your engine is a 360, it will work. If it was a 352, the comp. ratio will be really low. Like 6:1 or so. If it was a 352, you can swap in the 390 crank and use the rods already in there. If it was a 360, you have to use the 390 rods.

tHE PISTONS ARE ABOUT .020 FROM THE TOP. THE ENGINE WAS SUPPOSED TO BE OUT OF A 1973 FORD PICKUP. I CAN'T REALLY FIND ANY NUMBERS ON THE BLOCK TO KNOW WHAT IT IS. IT HAD A 2 BARRELL INTAKE AND TRUCK EXHAUST MANIFOLDS. I'VE GOT THE NUMBERS AT HOME FOR THE HEADS BUT I THINK THEY WERE C8AE-H. I CAN'T FIND ANY NUMBERS ON THE CRANK AND THE RODS ARE ALREADY INSTALLED AND I CAN'T SEE ANY NUMBERS ON THEM. MY PISTONS ARE 390 FORGED WITH THE 4 RELIEFS FOR THE VALVES.
THANKS

If they are .020 down, it's a 360. Sorry, but you'll have to change rods to use the 390 crank. The rods will work fine, I wouldn't worry that they aren't resized. Or, just run the 360. Use the 390 heads and manifold.
