289 OR 351 for '67 Fastback Mustang ??

I would like to hear some opinions, my '67 fastback currently has a nearly stock 289 2bbl with only a mild cam, no headers, 3 speed manual.

I have this '75 Granada with a stock 351W that I'm thinking of swapping into the 'stang, which is not a race car, just a street cruiser, I think the 351 would make for a more pleasureable ride becuase of the added torque of the bigger motor, and I may also add some performace goodies to it, the usual manifold, carb, cam, headers, ignition, etc.

the thing is it will cost me the same for performance parts for the 289 and the 351, which engine would you guys use?

thanks for replying.

Augusto.

Personally, I would go with the 351W from the Granada . Why not rering it while you have it out and have the heads rebuilt ?

I went with a 351 base motor in my 66. But then i stroked it to 408. The engine bay is a tad bit wider in the 67 so you will have no issues with sticking that motor in there. Plus it will give you alot more room to grow in the future. Some people try to say that a 351 adds alot more weight to the front verses a 302 but you really wont notice the difference. Its only a difference of about 25-40 lbs. Swap the heads and intake to alum. and you have just about covered that right there. Go with the 351 and you will never regret it....

Always - a 351W if you have a choice. While a 289 might be a high revving engine, you don't always need those revs and torque ..... nice pulling, especially if you like to tour the Andes.

Weight wise: 289=460 pounds (209kg),
351W=525 pounds (238kg)

I'll definitely go with the 351, and I'm also thinking using the C4 that is already attached to it, I bougth the granada to get the power steering that the 'stang lacks but now I think I'll use the whole front end, disk brakes etc, a little more modern stuff, I'll also need the pedals and steering column to make it automatic, this will make the mustang a very nice cruising car, that will perform as good as it looks, (ferrari red with two white stripes) the granada rear end is the WER-T 3.75 inch with 3.07:1 ratio but I believe the 'stang's 9 inch is a better choice, not sure if it's a 3.50 or 3.89 but any is a better choice, the power brakes may be nice also, not sure if there's room for the booster though.

thanks for answering.

I vote 351w also plenty of room since they did come out with the big blocks in the 67s. JMO

Hang on to that 289 though.

You will be very happy with that setup in that car, My vote would also be for the 9" in the rear. Chances are it has the 3.50 gear which would be a good cruising gear. If you have a little extra $$$, check out this company here http://www.autoworksparts.com/brake_systems.htm The electric Brake Master cylinder system might be what your looking for. takes up the same space as a normal master cylinder and the pump can be mounted any where out of the way. Personally I am using the dual brake master cylinder. My car isnt on the road as of yet but I'm very interested to see how its going to work out.
