what to do

fordkid68 · 02-16-2002, 02:16 AM

ok I am buying A 66 mustang from my older brother. it is in sorry shap but that why I am buying it. it's A 6cyl but I want to convert it over to 8 after I get the body and interior fixed up. so what I want to know is what can I do to the 6cyl 200ci engine to give it more horses until my v8 comes along. I am really looking at carbs and exhaust. I have never seen A manifold for A 200ci engine that will take A 2v carb. so whats out there on that issue. and do flows help performance I thought they did but then I heard they can cut performance down.

sorry for the spelling it's late and I just got off work.

thank for all that help.

Do not know much about the old v-6's but I would look at holly Carbs and see what the have. Flowmaster will increase horsepower unless you get too big of pipes. You have to have a certian amout of back pressure or you will lose HP. The new ones if you go over 2.5 inch exhaust you will lose horsepower instead of gaining it. Well good luck and tell us how is comes out. Also get magizaines they will also help from ads and other stuff.

Different places have different magizanies. I would go and read the index at the store and see if anything might help you. Also Muscle Mustangs and Fast Fords have good tips and good ads to find where to buy things at. Hope this helps.

Go to www.cliffordperformance.com they have lots of stuff for the 140/170/200/250 family of engines.
As for your intake manifold, i had an '83 zephyr (with the 200 straight 6) and the intake manifold was welded to the head (it was a bar) and if yours is similar then there's nothing you can do to increase flow except make your own intake manifold. The 250 cylinder head had a larger intake manifold "log" that flowed a little more and could probably be picked up for cheap.

Exhaust work would be a good way to go considering how restrictive the exhaust is and as for a 2 barrel carburetor, clifford sells adapter plates to change the stock 1 barrel to a 2 barrel.
You can pick up a header or split headers for an arm and a leg and have custom exhaust made, but it's not really worth the money. You could also have the stock head extrude honed (www.extrudehone.com) so it can actually flow something that doesn't smother the engine as much.

I know a guy who restored a prototype shelby mustang GT200 (straight six) and the stock intake was cut off and a new one put in it's place.

There's not a whole lot you can do to make power with those engines since they're so gutless it's not really worth your time to try and make one fast because anything you do without major changes to the intake won't yield you a whole lot of power for your dollar.

Good luck,
