forgive me for asking a question that may be obvious to some...I have a 65 fastback that allready has a 9in. 4 wheel disc. I tosted the 302 and it seems the 351w is the way to go. I would like to do a little road racing with the car but still stay streetable. Would it be wise to stroke it? If so how much. The 408 and 427 strokers seem to me It would wear the motor more than use it. Will a built c-4 hold the power? Any info, remarks or links would be greatly appreciated. Thanks Dave

Dave,

The 351w built with aftermarket heads and a built c-4 will be scary fast for a street car and awesome for the ocassional road race. We're going to a 408w in my daughter's '66 from a 351w, but it won't be very streetable or last as long. How fast is the 351w you ask? Plenty fast for the street, 0-60 in 4.something, 0-100 in 10 seconds the 1/4 mile in 12 at 110mph. Now the 408 should do the 1/4 in 10 something at 125mph+. How fast do you want to go and how reliable do you want to be? The 351w unstroked can and will last a looong time. BTW, a built c-4 (rollerized w/hardened input shaft and the best parts) is good for about 550 h.p. or more. Good luck,

SteveW

Yep, my c4 has lasted 350 passes this year alone running low 10's every pass with a best of 9.97 @ 135 mph. The c4 wouldnt worry me one bit in a street car. Thats what will be going back in my street car once I get some funds to put it back on the road.

ok now that my brain is more warped that before from all the research and reading.
It seems that a stock 1969 351 "W" 4V

Maximum Horsepower 300 BHP @ 5,400 RPM
Bore & Stroke 4.00" X 3.50"
Compression Ratio 11.0:1
Mains 2-bolt

Intake 2.185"-2.195"
Exhaust 1.7045"-1.7145"

Long Block Weight
530
QUESTION??? suposedly the windsor heads are junk so if I use aftermarket aluminum heads and intake, bigger cam won't this pony move?
IS this too much compression for pumped gas?

What are these specs from? A 351 Cleveland maybe, a 351W no way.

It's real easy to build a 351w with aftermarket heads to 400-450 h.p. and still be streetable. Keep compression around 10-1 w/iron heads and 10.5-1 w/alum heads.

Good luck, and don't let the facts snow you. You're thinking too hard.

69 4 barrel 351W was rated at 290 HP and 10.7 to 1 compression.

Yeah but, look at the valve sizes.

The info came from thecarsource.com claiming to get their info from multible Ford sources???? either way 290 to 300 is still close.
Q: are you talking about getting 400-450 from a 351w. Is this with stock crank or a stroker?
thanks Dave

Just keep in mind, you're feeding "big block" cubic inches through small block cylinder heads.

If you are going to install the required heads to support the extra inches, go for it! If you're going to try to feed the stroker with a set of stock or aftermerket "street 302" type heads, don't bother. Using the available large volume aftermarket heads out there, stroker 351W's are tough to beat!

Good Luck!

I'm leaning towards the 408 stroker but that still might be too much power.(heh who said that) I don't want a tire spinner I want usable horse power.
I have heard you can compensate by cam and carb-by not using a double-pumper and using a vacumm adv. carb you can roll out of the hole for traction purposes

what do ya think

What kind of road racing? Autocross, SCCA stuff? Either one and a std. 351w built to 400+ ponies will make you a happy camper! And will last a long time. Look at the Edelbrock RPM Package, but don't use their carb! Use a Holley 750 vac advance, w/10-1 compression. A proven package for the unstroked 351w with over 400 h.p. If that's not enough we can improve on it with some different parts up to near 450 h.p. No need to stroke it for what you're doing.

Chip,

A 351w is lighter with aluminum heads, intake, and tube headers!

I think a stroker would be counter productive in an auto cross car. I would put the lions share into the unsprung weight, and build a trick little 289 rod 306 with killer heads and run a bunch of gear, especially if it's a weight to cube deal. A hooked up, good runnin 408 is gonna go straight no matter where the front wheels are pointed . JMO .

yeah, I live less than 1 hour from Willow Springs.
I was not aware you could get that hourse power from a non-stroked. Stock does sound better for my application.

Thanks everyone
