300 V8 and Dual Exhaust

[grayta]

I'd like to put a dual exhaust on my '66 'Lark, which has a 300 CI V8. I assume that this engine came from the factory with a single exhaust system only, 'cause I've yet to run across a dual exhaust set-up for it. However, I do see duals advertised for the '66s with 401 or 340 engines. So, my question is: Can I use the headpipes from a 340 or 401 on my 300? Or, if they will not bolt on directly, can they be adapted? Or, is there another product (i.e. something from a 215, 350, etc.) that I can use? Since no one makes headers for this engine, using the stock exhaust manifolds will be a must. Also, I'd really like to avoid cutting apart my "Y" pipe, so I'd really like to bolt to the manifolds with something. Suggestions?

What is limiting you from using your existing manifolds for duel exhaust?

I'm not certain if anyone makes a pair of stock headpipes for a 300. I know I could fabricate some, but I just wondered if the 401 or 340 headpipes would bolt up and have the correct bend(s).

I haven't seen any pre-fab dual exhaust kits for your engine that don't require headers.

Poston Enterprises advertises headers for 300/340 engines. They are not cheap.

Why bother unless you are going to race the car?

The stock manifolds are pretty efficient. Just have a local muffler shop bend you a set of 2" pipes from the manifolds back.

I've spoken with quite a few 300 owners who did that and were happy with the results.

No, no racing involved-just trying to pump every bit of performance I can out of this little engine. I definitely am not going to bother putting headers on it, so I guess I'll contact a local shop. Thanks for the advise.
