will the distributor, intake and trany from my stock lo3 work on the 327. And can you tell me if any other part will not work.

 

The distributor will work no problem. You'll have to modify the center intake bolts with a drill because they're at a different angle. But otherwise the intake will fit too. The tranny will also fit. But you'll need a different flexplate/flywheel. The 69 motor has a 2 piece rear main and the lo3 has a 1 piece seal. They use different flywheels because of it.

BTW, I'm currently running a 68 327 in my 87 formula.

PS.. if the motor doesnt currently have accessory holes in the ends of the heads you'll need a newer set of heads. 305 and 350 heads will both work. L98 heads would be a really good match. Plus theyd fit your intake without any mods, and wouldnt change your compression ratio.

 

The dipstick is on the driver's side, and the tube won't clear the stock exhaust manifold (at least not without major bending/distorting).

If you install headers (a good idea even on an LO3), then you shouldn't have any problem.

 

I keep seeing this... Driver side dipstick won't accept stock exhaust manifolds. I have a 78 350 (driver side dipstick) and why would you take the exhaust manifold off the 327 and swap the 305. there isn't an advancetage and if you arre doing a motor swap why wouldn't you get new exhaust like i did.

 

What all did you get for new exhaust?

We all recommend upgrading the exhaust while you're upgrading the engine. However, some people are funds-limited, and are trying to do the swap in steps. One big step is headers, and people often say "I'll do headers later when I can afford them." So, we have to tell them that their stock manifolds are going to cause a dipstick problem (and the old 327/350 exhaust manifolds won't fit in our 3rd gen chassis).

 

Actually forgot about the manifold/dipstick problem... I did manage to get the drivers side stock dipstick to work with the original bird manifolds. It was squeezed quite tight between the manifold and the head, AND it got VERY hot! Couldnt check oil without lettin the motor cool down first. So you can get around that problem.. However, if you try to use the 327 heads, even if they have accessory holes, they probably wont have the 7 hole exhaust manifold pattern. So you wont be able to bolt the manifolds to the heads anyway. Headers will cure both problems, heads will allow the manifolds to be used, but you'll have a screwy dipstick.

 

Slightly bend the dipstick untill it touches (or is close to touching) the cylinder head, then remove that sheet metal wrapper on the manifold.

After you removed that wrapper, you will have enough of a gap between the head and manifold to pinch the dipstick tube between them and still be able to get the dipstick in and out.

A friend of mine did this on his 350... wish I thought of that when I put my 350 in, lol.

Works great though... just be ready for about 2" of your dipstick blade to turn blue, lol

 

You will need a flywheel for a two piece main seal if your using the T5.

Oop! Just noticed Chevymad already pointed that out.
