1966 Barracuda engine swap to a 340 Six Pack

Hello FABO members ! Its been awhile since I've been on here (excuse my absence) but boy do I have some news for you all!

Recently I came across what I think is a pretty good deal for a 1968 340 motor. He even wanted to throw in a 68 date coded small block 727 trans with a brand new torque coverter for a couple bucks more. Problem was, the trans needs complete rebuilding and I know for a fact I need to do serious mods to make it fit. The motor is almost complete except its missing headers, intake manifold, and other misc. parts to actually make it run (pumps, carbs, etc). It does have some brackets and seller says that if I build it up, it will run. Not taking my chance on that though, if I go through with it, im rebuilding it all.

The good news is, I have a 318 motor currently in my 66 barracuda. I know all of its accessories will be a straight fit to that 340 :).

But heres the crazy part...

How about I build a six pack on that 340 and place it in the barracuda? Now, that would be the only reason why I would buy the 340. Problem is.. im not exactly all that techy or experienced to do it myself. Heck, ive never done an engine swap before.

I have done some fair and hefty research on this.

Heres what I know:
- The 340 was semi-prepped for the track the man told me. I think he said it also has a low cam on it. (I partially have an idea of what the differences are between a low and high camshaft)
- It has a big block oil pan on it (he was going to also throw in an appropriate one for my 66)
- It has been sitting for a while
- Headers are an extremely tight fit once placed in (and hard to find)
- I believe its the left side motor mount that needs to be lifted or have washers added? Cant remember exaclty what it is now.
- The original 7 1/4 rear end may not hold it.. may need to upgrade to an 8 3/4
- I'm going to need a torque converter for the original 904 thats currently in it
- Six pack set ups are expensive
-... real expensive
- Hard to find that set up as well
- More GO power = More STOP power
- One more thing I know and I just cant recall it now.. :mad:

What i semi-know:
- I NEED AC! I saw before an AC unit attached to a six pack on a 66 barracuda here on FABO.. I'll have to go back and search it as he gave his entire description as to how he did it and the information of the products he used.. Man was it beautiful. So I know its possible, but at what cost?

What I dont know:
- How much HP I'll get out of that 340 with the setup
- What heads are on the motor
- Can I even do the six pack setup on a 68? I know it was first placed on 70 motors
- Any suspension modifications that I have to do?
- Will frame twisting be a problem?
- Drive shaft?
- And pretty much any information/tips you guys can provide will be awesome.
- My Barracuda has AC and PS, will it be an influence while placing the 340?

Now, heres the craziest part of it all. I have about a 4k budget after I purchase that 340. Yikes, I know. I'm wondering if i can purchase everything with that and get straight to building. I dont want to buy some parts and then have it collect dust for some time as I try to make the $$ for whats missing.

Yea... I can play with the budget a tiny bit.. but lets try to keep it at that guys :)

Ladies and gents on FABO, please help me out with this dilemma. I am very eager to jump in on it but I dont want my emotions to get involved as I know my wallet will kill me.

Also! Anyone with a six pack set up they want to sell?? :lol:


Thanks !!!
