the bolt pattern for the truck 390 and your 360 is straight up and down, one obove the other.

You may want to rethink that answer. Casting # C8AE-H has 2 different bolt hole patterns. The vertical 8 bolt pattern was on full size cars and trucks. 2 bolt holes vertical per each exhaust port. The fourteen bolt pattern was used on Mustangs, Courgars, Fairlanes, and Comets. Why? Those cars sometimes came with the rare factory cast iron headers. Therefore, those cars with the factory headers, will not accomadate aftermarket headers. They are missing the bottom 2 bolt holes in the center 2 ports. Hot Rod magazine October 2005 page 151
GT heads use a different bolt pattern, but he didn't reference GT heads.
I stand by my original.

You said there was no difference in car & truck heads, but there is as far as exhaust bolt pattern. Are C8AE-H just GT heads with 2 different bolt patterns? Not according to the article. They are common 68-71 heads on 360, 390, and 428's, including the 68 390/265 or 315 hp, the 68 428/340 hp. and the 69 390/265 or 280 hp. Let's not forget that some larger FE's were swapped into these trucks just for the fun of it.

IIRC there are some differences in wrist-pin heights and/or rod-length to yield a much 'hotter' engine than the later truck 360
Others have brought up possible exhaust manifold issues, there's been enough years gone by that some swapping might have happened on either end, so an 'eyeball' check might be a good idea

The OP *would* be smart to verify which exhaust patterns he's dealing with before laying down cash, swapping happens, especially when folks like us get involved

You can stand by your original all you want ....but you really stand CORRECTED! When someone asks a question, you can't give a pat answer anymore. Such as "Yeah it will fit." Too many varibles. Who knows what has been swapped. But we can say "This is what to look for." For the OP the engine may have been replaced with something more potent. I have seen it done. A racer retires, sells the car minus the engine. Keeps the engine for a few years, then decides to put it in his parts chaser. Forgets it is in there or doesn't care, and sells the heap to the kid down the block. Let's help these newbies a little better shall we?
