Engine upgrade

[Anonymous]

This sight has convinced me to upgrade my 67 200 Mustang Convrt. despite most of the advice to swap to a V8. The information and advice on this sight is awesome. I am seeking advice on Autolite 1100 3/1V on an Offy v. Weber 38 2/v on an adaptor. For now I plan on cam kit (264?)
and headers with my stock automatic tranny and the stock 2.83:1 rear. What should my performance and reliability expectations be. And any other info would be greatly appreciated.

Any combination of those will give you great reliability. As far as performance, it will be minimal. My advice is really evaluate what you "want" from this car as far as performance, then ask us if it's attainable. If you want a zippy, fun car, then what you've mentioned will provide plenty of smiles.

here is my review of the offy triple intake:

The main reason I went away from the offy is I wanted something more simple. 3 carbs is just a lot of tuning. Once you get it tuned, you'll have gobs of power. It in theory at least is a lot better power wise then a 2V adaptor on the log head. Remember, the main draw back of the log head is the log and the lack of breathing ability. The 2V adaptor only allows you to run a larger carb and that helps relieve some of the breathing problem, but you are still stuck with the log and still shoving air and fuel through the same small intake hole. With the offenhauser, you now have a carb basically feeding every 2 cylinders. Great combination.

Howdy Buztang:

It would be most helpful to know more about your vehicle- trans, rear gear. About your long term goals for this rig, and about yourself. Are you a competent mechanic, hire stufff done, or....

The three ones is a major undertaking but unequaled in coolness. The Holley/weber is a fairly easy bolt-on swap using an adaptor.

Is your convertable a daily driver? In either case, it would be best if you were to have a complete plan for this Convert before you start and before you can answer this carburetion question.

Adios, David

David asks a very important question. I forgot my answer to it when I did the offenhauser. Some people have had success with it for a daily driver. I did not. But then again, I drive 100 miles a day 4 times a week, for 8 months out of the year, in my 65 vert. It was just too much driving for the offy.

But it is the ultimate in coolness at the shows.

I have started going down the Ausse 250/2V path as I believe that is the best way for power and drivability, in my particular circumstances.

Hi guys, thanks for your responce. I have a pretty good idea on what I'd like the end result to be. I have had the car since 97 3rd owner, the car was pretty rough mechanically and cosmetically. I have messsaged it into pretty good shape. But I am tired of the performance someone on this sight accurately discribed it like a UPS truck. I am in the process now of improving the brakes and suspension. The brakes will remain drums but I am adding a power booster and going brand new w/ drums, wheel cylinders and hardware, this I am doing myself. Once finished with the brakes I am having the suspension done. I have not purchased the parts so feedback would be timely. I will at that time have the head work done and have the headers and cam kit installed. That gives me time to detail the block and engine compartment. The plan is keep the stock auto trany and 2.83:1 rear for now, the next stage would be T5 and improve rear ratio. This car is a cruiser only no daily driver but she sees lots of road.
I can do just about everything mechanically but time and garage limit me. I will do as much myself as time allows, fortunately over the last 6 years since of owning this car I have a pretty good budget for this build. Unfortunely on projects like these money goes a long way to budget time.
Sorry for going on so long I hope this add"l info provides a better idea of what I want to do, I want to get it right the first time. Thanks
