New Stroker Motor for 1967 Fastback

Any of you folks done a stroker for your classic mustang? I'm having a 351W bored and stroked to 427 c.i. Currently, I have about 260 rear wheel horsepower with a 302. This is connected to a Richmond 5-speed (which I will re-use). With the new motor, I figure I should have at least 400 rwhp. If for some reason going from 260 to 400 is not enough, I can always add more grunt.

Here's the grocery list:

• 1969 351W block with 4.060” bore
• Motor was hot-tanked, magnafluxed, line-bored, decked, blue printed and balanced
• SCAT Forged Crank with 4-1/8" stroke and large radius journals
• SCAT 4340 steel h-beam connector rods 6.2” length
• Keith Black hypereutectic flat top pistons
• Crane Roller Cam
• Cam intake duration at 0.050" is 236 with 0.574" lift
• Cam exhaust duration at 0.050" is 244 with 0.595" lift
• Canfield 2.02 - 1.60 aluminum racing heads with 70cc chamber, powder coated old Ford Blue
• Estimated 10.4:1 compression
• Edelbrock Performer RPM Intake powder coated
• Edelbrock 750 CFM carburetor with electronic choke
• Comp Cams roller rockers 1.6 ratio
• Billet steel main cap girdle
• Melling high volume oil pump
• High volume Carter fuel pump with integral filter
• Holly fuel pressure regulator and liquid filled fuel pressure gauge
• Performance push rods
• Crane Electronic Ignition with built in rev limiter
• Crane Fireball Coil
• High volume water pump
• All polished stainless steel bolts with Ford Oval logo

Just wondering how many others have gone down this path...

I know the saying “you can never have enough horsepower.” But, I’m not addicted to horsepower. I do have a taste for it (my daily driver is a 2003 Mach 1). For something more, I’m thinking my next project will be a race car; a combination of a road car and drag car. Yeah, I know, one or the other will maximize the car’s capabilities. But, I can live with the compromises. I already have a car sitting in the driveway begging for mods. Anyway, I know this would satisfy my spontaneous power urges.

My 67 Fastback is strictly a show car. I already improved the cooling and I already have custom sub-frame connector welded in. Four wheel disc brakes and other upgrades will be done before next year’s show season starts. In the future, I may take it to the strip just to see what it does. But, I won’t really “race” this car (I have too much money invested to risk it).

I drive my 67 to shows. No trailer. I my opinion if you can’t drive it, it’s no fun and not worth it. Anyway, I don’t want a real rough idle and I doubt I’ll ever use a power adder (I never say never). The longest drive it’s had is about 3 hours; from Portland, OR to Bellevue, WA for the big Mustang show is July. And I hope to get it there again next year. Most of the drives are less than an hour. The car gets about 1200 miles per year.

As for the pistons, engine components can be controversial; just like the Ford vs. Chevy debate. Some people ONLY use one brand of carb/cam/oil/intake/etc., others ONLY use another brand, and some don’t have a strong preference. It’s been 20 years since I physically built an engine myself. But, I did a little research and didn’t see any negatives to the Keith Blacks. My engine builder use to build race car engines and he likes the Keith Blacks (he also knows how I drive and care for my 67). So, I have to ask you guys, what specifically is wrong with Keith Black pistons? Are the negative comments due to preference? When you state use a different piston, what would you consider to be good, better, best? I would like to see how your opinions line up with mine.

Regarding perceived problems with Keith Black pistons, I still don’t see anything specific. And I didn’t see any opinion on which piston is good, better, best. I’ve know a lot of engine builders who have had problems with a lot of different things. But, that doesn’t necessarily mean particular parts/brands are crap.

I think I understand the concern about “fragging” with a power adder. And again, I don’t like to say never. But right now, I am definitely not considering one. And in the future, I just can’t see me putting a supercharger or something on this car. Who knows? Maybe on the race car. But, that’s a whole different ball game.

I guess I should have known posting the grocery list would create another discussion. I do realize the cam, intake and carb can be changed to improve hp/tq. I appreciate the opinions and input. And I encourage more of it. But, it’s my car, my money, and my motor. I’m happy with this combination/setup. And I can’t wait to drive it home. But, I posted this to see how many people put a stroker in their classic Mustang. I’d like to know who did what, how they like it, and how they use the car.

KBs get an undue rap because they were misused...

If the top ring gap is not set correctly for the application, the piston land will break off and some may think its because the pistons are cruddy when in reality it was installation error.

All rings will have more problems sealing in a stroker due to a short skirt and piston rocking causing instability of the ring face.

No rhetoric...just facts.

You've made a good choice...just be sure they are gapped correctly.

blkfrd,

This is exactly what my engine builder said. He has been successful with many engines using KBs.

What was the question?

I think that's called a two-stroke.
