6 to 350 Swap: Will stock 67-72 Ram Horn exhaust manifolds fit an 80's 350? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Davids71C20 · 12-15-2013, 08:14 PM

I'm swapping my 6 for a 350 and I'm wondering if the 67-72 Ram horns a got will fit a GM Crate motor #10066036. I pulled it from a 1981 C10. I skimmed over something on here just mentioning that they don't fit but they didn't elaborate so I'm looking for more info. I know I'll probably need to change the dipstick to the driver's side which is going to be tough since its already in the truck with the oil pan on and I have no idea how to get the stick filler rod or whatever that thing is out or what I'm going to plug the other side up with.

My big thing is the manifolds because I'm on a tight budget and I've already spent a lot of money on this swap so if this doesn't work, then I might just rebuild the 250 and sell the 350 67-72 stuff.

I appreciate you input. Thank you.

I have rams horn manifolds on my '95 TB FI engine, fit and work great.

That dipstick tube will slide out if you start to wiggle it back and forth for a while. While the manifolds are off you can plug the hole from the hole by silicone [my last option] or rubber plug of some type. Not all that hard. Jim

Are you referring to the current dipstick or the driver side filler stick? Also, is that a filler stick or is it the lower dipstick tube that I will need if I get a 67-72 dipstick? Apparently there are two parts to the tube and then the stick.

Thank you everyone for your input.

There's no need to mess with the dipstick. If your new engine has it on the passenger side, just run it. If its on the drivers side, run it. It makes no difference.
