Under Construction

[vtgt500]

My TX 66 notchback going back together with Group II mods.
sat in storage in Ft Worth 1984 ~ 2008

289 +0.040" going back together with 1969 351W heads, exh ports opened up, intake ports cleaned up

I too had a 70's vintage Ford Muscle Parts Stage 5 Dominator 302 build.  Included '69 351W 4V heads cut for GT40 valves,  Crane roller rockers, C90Z-9424-D intake, C7FE-6250-A LeMans cam, 12.5:1 pop up pistons, and Boss 302 balancer.  The combination worked amazingly well enjoying it for many years.  Still resides on an engine stand awaiting a Falcon restoration.  Only imagine what current cam and head designs contribute.

this is still in the collecting parts stage ......67 289 auto originally britney blue with black deluxe  interior. I bought it from a retired d/c police officer  car has a bad 80s paint job on it . but structurally it is  very clean . the vinyl roof has rusted the roof pretty bad . SO if i have to cut the roof and 1/4s off i might as well put fast back parts back (evil grin)  back to brittney blue  and black interior  331 / 347  /427  stroker small block  manual trans . daily driver kinda day 2 car  ......non resto mod   . Something that gets used all summer  and  i can take anywhere .

6R07mi, I didn't know you could put 351 heads on a 289. How much hp do you think it will make when you are finished with it? Can both Windsor and Cleveland fit on that engine? What about the 351 M. What does M stand for? I was told Mitzer.

'69 351 heads had larger ports, but also larger combustion chamber requiring pop-up pistons.  In the old Muscle Parts building guides, it was the head of choice for Stage 3 & 4 builds.  I'll find the pages and post later this weekend.

It is a advantage for early high compression engines to be able to lower their compression ratio slightly to run better on lower octane fuels and also benefit from better breathing. Not a factor back when when premium gas was 98-100 octane but now when you are lucky to find 93 octane lower compression ratios are factor on pleasure driven cars. The 351W head would be a budget minded modification now days. Of course any of the after market aluminum heads are a better performance choice over a stock 351W head.

Snakebit, the old Ford Muscle Parts Catalog outlines the different "stage" mods for the different engine familes,
The 351W heads are a "poor mans" GT40 head upgrade, it requires different head bolts / fasteners, matching the water ports with the intake side gaskets. HP expectations are related to compression ratio, cam selection, porting, carb etc.

If competing in vintage organizations that do not allow modern aluminum heads, only period iron heads it's one option.
The fast guys are likely cheating anyway, I don't have the big budget and wanted to build a true 60's era mod motor.

Mounting a 351 C head = Boss 302, 351M ( M=Modified ) heads are not worth messing with.

Thanks everyone for filling me in on the 351 head info. So, the Cleveland heads are really the only ones worth using. Ok. Thanks.

Cleveland heads can be used on a Windsor block. NASCAR has been doing that for years and has been copied by the other manufacturers. They live at high RPM's.

Of the 60's Windsor iron heads, '69 351W heads are some of the better heads but not the only good Windsor head.  😎

Also will need new headers it all ads up to some $$$$$ but you will like the results.

The new chassis arrived last week - now the fun begins!!

[SNAKEBIT]

Hey, nice, new frame. Is that going to be heavier than the original style one? It'll be nice and stiff.

[kjspeed]

Snakebit - The AME frame is somewhat heavier than the equivalent stock Mustang parts, but I'm going to trim weight wherever I can. Thinking of doing Lexan side windows, aluminum fender aprons & floorpan to save a little weight. Dove is building me an aluminum 427 tunnel port so that will be considerably lighter than the original 390 and have an extra 300+ HP. I'd love to bring it in under 3100 lbs. but I do want to retain the fold down back seat, install a roll bar and Vintage Air heat & A/C so that may push it a little higher. I'm sticking with the original C6 mated up to a Gear Vendor's overdrive (more weight) with a 3.89 rear gear. Hopefully that's enough to move it down the road.

Hows this?

[kjspeed]

Yikes! Get that fellow some suspenders or one of these.

I've not seen a scale model done up as a barn find - that's pretty cool!

Thats what my car looked like the day I got it, I had that made, with pictures I send the guy, notice the color change that was in progress form a previous owner? Here is it today, I went through HE double hockey sticks to get that car done!
