Some of you may have seen my recent ticket back into the '67-'72 truck world via this thread:
http://www.67-72chevytrucks.com/vboa...d.php?t=211903

Anyway - I found out that the Tranny shop put some long bolts in the coverter, broke one, and the other 2 wern't tight. Luckily it didn't damage anything but the treads in the converter.
(I also think they put metric bolts into SAE theads)

So being that the truck had a massive oil leak anyway I decided to pull the motor out so that I could re-seal the motor and fix the converter.

Here is the Dilema:

Upon removal of the motor Today I found out that the motor is not original to the truck.
Looks like sombody put a '62-'63 327cid in it with some '70 or "aftermarket" 492 Heads (they'll be on the shelf in my shop for future use)
The motor is has the small main journals so you can't put a 350 crank in it. It is basically only goo do someone who needs a '62 or '63 327 for thier "original car"

Not to mention that the Carb is a big Holley 780CFM (3310-1)

So this truck isn't anything overly special - so I'm debating do I get a set of used heads to put on the 327 and shove it back in?
do I put together one of the '89 350 1pc Seal Blocks I have together and run that.
The short stroke of the 327 was probably why it seemed to be reving a bit higher as well - not that it makes that much of a differance

What would you do? Got and cheap torquey 350 combinations that I could use to put one together?

And a GM Crate is out of the question right now (I know they are only $1400...but can't do it) I would rather try to throw something together for a few hundred.

I really don't think the truck is worth of that kind of motor - and def. not the heads. The 327 with those heads should be saved for something light that needs a quick revving car - not a truck that wants some torque.

Thanks,
Andy

ps: look @ that greasy mess
