Yeah....

I haven't done too much research into this, but my understanding is that you're pretty much screwed, lol.

You can mill off the intake manifold and have a different one put on there that will allow for a better carb setup (triple weber sidedrafts would be cool), or you can go to fuel injection (maybe).

You might also be able to find a different head for the motor (maybe off a 250 or a 300).

Good luck with it man.

If you use the clifford 2v adapter you can get the Holley/Weber 2v carb from langdon's stovebolt.

The CI adapter is for carbs like the Holley 350cfm 2bbl.

use the 250 head.has a bigger log runner for more air flow and bigger valves.76 granada 250 is good.300 will not work.

with the 250 head, don't you have to perform some mill work? I have heard that it involves a lot of machining to get it to work properly.

If you use classic inlines adapter go with a Holley 350cfm 2bbl.
If you use clifford adapter go with Holley/Weber 2bbl.

Ok, 6 cylinder performance guys. So far, I have a clifford header leading to 2.5'' exhaust with flowmaster 40 series mufflers, flexalite fan (for the hot summers), and pertronix ignition. I just spent a sh*t ton of money on a ponycarbs Autolite 1100 to make the car run smoothly. I am seriously considering throwing on the 250 head (I found one in really good shape) and switching to a two barrell carb. It is worth it? Will drivability suffer? I just want a car that is fun to cruise in, but has enough power to get down the interstate with ease. Let me know what you think. Thanks in advance.

Mike

i also have a 289 under the bench. but i have been told the suspension and the 4 bolt axels can't take the stress ? as far as the weight the v8 can't weigh but a couple hundred pounds more . but ive been warned so there must be a reason. and off topic maybe replacing the 6 cyl. would take from the value. i dont know. just want a more responsive ride. so give me some ideas. thanks.

the i6 and v8 have different steering components, including spindles, tie-rods, centerlink, idler and pitman arm. The coil springs for the v8 are beefier to hold up that motor, and the 4-lug axle and brake system is different. And the Rear end is different.

You CAN keep the tie-rods, centerlink, idler and pitman IF you go with the CSRP Swap kit #2 from discbrakeswap.com. that will upgrade you to beefier spindles, with 5 lug Disc brakes. You will still need to replace the front springs and the rear-axle, though.

The Upper and Lower control arms for the 6 cylinder and V8 are the same, so you can leave those alone...though if they are older, they might require some inspection and freshening anyway. I recommend a new LCA, Upper Ball Joint, and Moog UCA Shaft Kit.

you're probably looking in the 1k - 1500 range BEFORE you build and install the motor, depending on how well you source your parts

Do you have to machine the intake manifold before using an adapter plate?
