parts i need to convert 360 to 390. any help is appreciated. i have tow 360 withone that has 390 heads i think???

 

We need a stickey with how to convert a 360 to a 390...

Simple version:
Anyway, you need to obtain a 390 crankshaft and a set of 390 rods. You use 360 pistons with the 390 crank and rods to get a good high compression 390.

Post the numbers off each set of head so we can tell you what you've got. Also post the block numbers. Numbers we're looking for are, for example:
Heads: D2TE-AA
Block: D3TE

 

ill check the #'s. what about the heads. do i use 360 or 390 heads. it would help if anybody had a 390 rods or even a crank that they would sell.

 

A great place to get your 390 crank and rods is the junkyard. There's plenty of pickup trucks (usually F250 or F350) out there that have the low compression 390's in them. Find one that doesn't have any spun bearings and go from there.

On the heads: A lot of times the 360 and 390 used the same heads. On late truck motors anyway. But get the numbers then we will know exactly what you have and what would work better.

 

ill call around and find one. thanks alot
