[68-408]

I have been viewing posts on this site for a couple of months now. This is my first post.

I am accumulating all of the parts to build a 408W. My 68 mustang has a 65 289 in it. Would the timing chain cover fit and work with the included pointer on the 84' 351 block?

Hello Welcome to the Forums.

Yes your timing chain cover would be the best one to use on it. so you could use the same water pump, with the water kneck on the passenger side still. And you use the pointer set up from your 68.

you might want to look at this site to see more info on a great 427W stroker motor.

It is a great motor for the price.

Thanks for the offer. I bought this mustang with a hope of having a hobby to occupy my extra time with. I have always wanted to build my own V8. I have already accumulated all of the parts for the build. I am just waiting for the machine shop to clearance the block then I will start assembly.

Good Luck,
Anything we can do to help just ask.

yah haha that car will still move good luck

now that you mention the water pump; mine was back ordered and just showed up. Guess what the water neck is on the drivers side. I was going to replace the radiator anyway, but I wanted to wait a little while.

-So now I suppose that I need to replace the timing cover to one with the pointer on the other side? Is this possible, would the marks line up?

-Also any good suggestions on a radiator that would bolt in easily and use the drivers side pump?

-Then how big of a pain is it going to be to get hoses that fit this swap?

Ok, As we look at Pandora's box.

a few thing I learned the hard way on a 408 Stroker build.

It is not a very cheap to build one from a 69-74 351W Thing are just diffrent. The new stroker kits are made for the newer 351W. We use the roller motors from the 80's.

If you use a 68 Timing chain cover you have to use everything from the 68, water pump, water pump pully, Crank pully.

If you use a Timing chain cover from any other year above a 68, Just remeber that you need to use every thing from that year.

ok the next big thing.

28 oz or 50 oz Balance

28 oz is what the older motor use from 69-76

This is important because the fly wheel are diffrent. 28oz is smaller 50oz is Bigger.
So if your using a older Transmission set up from you car you need to go 28oz.

Thanks again,

My new 351 block is out of an 84.

I decided to return the water pump for one that has the outlet on the passenger side. I wanted to use the 289 chain cover in order to save the stock oil dipstick. This will help keep things closer to original. Now I can at least get the engine started with the old radiator.

One thing to add is if your 351 block was made before October 1969, it has a different eccentric for the fuel pump that will not work with a double roller timing change. It's an easy fix, but can cause headaches if you don't know about it.

What kind of compression are you running with that engine to get 486 hp at only 6000 RPMs with that relatively small cam, and cast iron heads? or is it just that those heads flow that good?

Small Cam? If you heard the the car Hitting your wouldnt say that.
Cam Spec,



the motor is right at 10.2:1 , Runs on 91 Pump gas

This motor is just crazy fun. I just droped 1k to try to hook up the rear end. It is kinda cool that you can spin the tires at any speed.

I just install Cal-tracs and Nitto 245/45/17 GT555SR Tires Replacing the Fuzion 245/45/17 ZRI tires




RHS™ Pro Action™ cylinder heads are the perfect bolt on head for medium-displacement Ford Windsor-based engines. Ideal for 302 to 351 CID and 5.0L street/strip engines, Pro Action™ 200cc cylinder heads are the hot ticket to making up to 550 flywheel horsepower

[69fastback]

Well, I say small cam in realtion to some of the cams you see out there with those kind of CIs. A .500 lift lift straight across with a 230 at .050 duartion staright across is not what's considered a "big cam." I've heard the video and no doubt, it sounds awesome, and a lot of that sound comes from the 110 LSA, and 106 centerline, which is great for an engine with no power adder. That's close to the same cam I had in my white car, except I had a little more lift, and it was a roller cam.

I read all the specs on the enigne and heads off your website. Those are some impressive numbers for the specs on the engine. I wouldn't have guessed the numbers to be that high. Just another perfect example of no replacement for displacement. The more I toss the idea around, I'm considering driving up there and having you build me one. I'm so busy at work, I haven't had much time to spend on my 408 build.

[69fastback]

What do you think those TQ numbers would do to a stock toploader with a good clutch and flywheel?

[MustangOne]

We have 4 of those 427W going right now, I think you would like the tour of what we do here.

The Stock Small block Toploader be fine as long as you didnt put sticky tires on it.

Big block top loader be fine.

I think if you just feel the power you would be sold. The price is great. We have twice as much in the 408 we did.

I will be driving my car up there sometime to see your place. I'm debating on motor or paint.....

[68-408]

OK now a new round of similar problems.

On the 289 the timing pointer is on the drivers side. On the 351 it is on the passenger side. Is there a different set of marks on the balancer? Am I able to interchange timing covers?

[MustangOne]

This is the balancer you can use. It has both sets of timing marks and 3 or 4 crank pully.
