Hey, my 67 fastback has the 2 barrel carb on the stock 289 engine, not the HO with the 4 barrel... Its a bit doggy so I want to hop it up a bit with a different motor ( I think ). Any suggestions? Such as a 351W with a 4 barrel? Looking for something to make it even more fun to drive, not looking to race it by any means. Want to add AC to if not too big of a project.

 

Build yourself a mild 347 stroker using a 302 block. It doesn't cost much if any more to build than a similar stock stroke motor. 400+ very streetable horsepower is very doable and they have a TON of low end torque. The plus is that it will look like your stock motor and all your stock brackets and such will still work.

 

You can use your 289 block to build a stroker. No difference from a 302 block.

But I do agree, a stroker motor is a good option. I love my 331. Not to say a 351W based motor isn't a bad idea, but it all depends on budget and goals.

 

Why not rebuild the original motor. As you said, you are not looking to race, so a 400 hp stroker is overkill. You can easily a relatively inexpensively ring out 275-300HP and 350 Ft/lbs or torque out of the original motor, without stroking. This will be more than enough get up and go for you purposes, you will have the original motor ( aplus in my book) and no issues with trying to swap a diff motor (accessories lining up etc) also, getting an AC kit will be much easier to source with a stock set up.

 

Too right! Even if you stay with 289 cubes, you can build a streetable engine with over 300 hp. The 289 was used in champion racing cars.

 

I am in the same boat as you. I have a good running 289 in my car right now, but I also have a low mileage 351W sitting on a stand right beside it. Original plans were to go 393 but I think that might be a little much for a car I want to use as my summer daily. My plan is 351 with forged internals and alum heads. Should make it more streetable and reliable, but a step up from the stock 289.

What has more torque: 331 stroker or 351 stock stroke. both with alum heads.

Sorry to hi-jack, hope my questions might help your decision.

 

This is a good point also. There are quite a few things you can do to that 289 to make good power without sacrificing the streetability of it. A GOOD (read this as NOT a set of those cheap eBay special aluminum) set of high flowing heads will makes a TON of difference over the stock heads as well as a full blueprint of the motor. One things for sure, you have a LOT more options now days than when that car was new for making more power.
