i have a 65 mustang with a 200 cui six and have been reading a vit on them and thinking of keeping it and making a few changes to get a bit more power. i have a c4 tranny in a coupe, what i am thinking of doing is junking the lod o maticd junk dist. and going to a hei, but need to get vacume for the advance and my question is if i t off o f the vacume lind going to the tranny will mess up the shifting of the trans. there ios a port just below the carb butr not sure what the size and threds are the person that i got it from put a bolt in tht hole and may hve messed up some of the threads. if some one knows the size of that port i can get a fitting and try to use it or maybe rethread it and use. i am planning on using a webber 2v car and not sure if they have a prot for vacume if they do i will be ok. any way any info from those who have mor experiance with the six than i do.,
thanks jim

what size is it?

i'm not sure exactly what your question is . . your distributor vac line on a non load o matic typically goes to ported carb vacuum, nit directly to the intake . . with a non load o matic you do not need a distributor vac to make it run properly.
i would not spend the money for a weber.
i would take a compression test and if it is around 140 or less, i would mill the head to increase it if you run premium gas.
a header might help a little or maybe a 347 stroker...

the webber carb is cheaper than a new stock ford carb and its progressive so only using 1 barrel till you get in it, am also thinking of the header route also from classix and they have the adaptor for the webber carb aslo and may be a mild cam latter on was thinking of a v8 but read a few articles and think i can get t decent amout ov opwer from the six at a cheaper investment thanks fo ryou imput jim

unfortunately you can not get much poewer from a 6 unless you at least install a 250 head and mill it around .090" and possibly use a thinner head gasket to get the compression up.
a weber carb will do very little to increase perf on a 200 head due to the small intake runner . . it will only flow so much no matter how big the carb is . . also, the hole on the intake where it mounts must be the same size or larger than the carb.
if you want quicker acceleration with a 6 you must install 3.23 rear gears and/or a 5 speed trans and the gears are only available used.

Pertronix in the distributor and carb change...maybe... But my unsolicited advice on the subject of souping up a six is to save your money and enjoy the car as it was meant to be... slow and reliable with reasonable gas mileage. Put your money into a five speed conversion and you will have alot more fun with the car.

I have to completely agree with MS. I spent a lot of time and too much money years ago trying to get some "cheap" performance gains from my 6 cylinder. I finally installed a V8 (still an expensive project) but I have been MUCH happier with the performance and driveability of the car.
If you want a V8 car the best and easiest way is to buy one. You could also buy a V8 donor car where the body is shot and then transfer all the V8 components to your (good) V6 car. Sell what you can of the removed V6 parts to help offset your swap costs.
Or, as MS said drive it as is and save your money for that V8 car.
REMEMBER!!! When posting a question about your Mustang or other Ford on this forum, BE SURE to tell us what it is, what year, engine, etc so we have enough information to go on. |
