Forgive my ignorance, but a 351W is only ~125 lbs heavier than a 302 (stock), and generous use of aluminum components can about square that account. Does that require suspension work?
Just wondering, I havent heard of this before. ::
Not front end.
Rear susp./tranny/rear end/rim and tire.
My rear end floats enough with the 347. I didn't want to slap in a big motor and go in strieght line I want it to acctually handle too. I dodn't want to have to burn up a clutch everytime I launch the car.
I didn't want to half @$$ the install I wanted everything to work together and not have a weak link in the setup.
I'm considering a stroked 351 for my '65 someday, and the only suspension work I ever heard about is done using a big hammer. The 351 is big in the 65/66 bay, but not that big. Stock hood won't close and the shock towers need a little "modifying for headers to clear.
There is no suspension work required. Headers are a little tricky, and manual transmissions (clutch linkage) makes it a little more of a challenge. Other than that it's largely the same as a 302 swap.
I wouldn't hesistate to do it again.
Mine's a 388 inch 351 - 3.75 stroke, .060 over. There are several on the forum with 408's, but I don't know if I remember anyone with a 427 W. I do know a guy with a '57 Chevy that has a 427 W in it though !! With an intercooled turbo..
what some may be referring to as "suspension work" in relation to transplanting a 351, especially a stroked one putting out EVEN more cubic inches, is the amount of TORQUE produced by one of these "potential" torque monsters. While upgrading the chassis on Xtremestang (ie subframe connectors, Stage III Global West setup, 8 point rollbar/cage), my friend who constructs racecars pointed out several areas on the unibody where STRESS TEARS had begun (requiring gussetting), all of this with a stock C-code 289-2V....
keep in mind that these 30+ year old unibodies were never designed to handle LOTS of horsepower and torque. True, some of the more "elite" (Bosses, Shelbys, Cobrajets) received "add-ons" to help cope with additional power. In today's age of techno this, that and the other, it is not uncommon to hear people pushing for 300, 400 and yes even 500 REAR WHEEL HP and beyond in an otherwise stock chassis Mustang. Like with anything else, when you upgrade one system (ie drivetrain) then it is reasonable to expect upgrades in other areas. As you add more and more power (especially torque) you can see the potential to literally turn your old Mustang into a driving "pretzel". In the past, most were concerned with stock restorations with primarly stock rebuilds and MAYBE an upgrade of a set of headers or maybe 4 barrel carb and intake. In today's world, we are now pushing for large cubic inch engines in smaller, lighter packages putting an enormous strain on an outdated chassis....
I would STRONGLY suggest anyone contemplating on building a stroked 351 potentially making gobs of horsepower and torque CONSULT someone who is well versed in strengthening the chassis to handle any increases.....
I assumed that the 57 Chevy had a stroked 351W (427) in it from your post. That being the case, I'll bet it tightens the strings of the bow-tie boys, particularly being intalled in such a bow-tie icon. Regarding the strokers.... I gave serious consideration to a 351W for the 66 (even collected several), but opted for the 302 stroker in the end. This was mainly a size, maintenance, and weight decision (65-66 cars). The 351W can be made lighter, but the 302 is that much lighter again with the same aluminum parts. Everytime I change plugs or adjust the valves, I'm happier with the decision. Besides, the 342" is scarey enough for this old geezer anyways.
I was running out to lunch when replying last that is exactly where I was going with that. I would have been making some serious chassis bending torque if I would have used all the components I wanted to. I apologize to everyone for not saying "making the (What I feel to be) necessary mods to the chassis."
Do they burn oil like the early 347's used to stuff like that is what I am looking for. Thanks and sorry for the confussion.
I'm running a 393 Stroker. It's making about 475 hp and has massive torque. I can outrun my buddy's 502 c.i. '68 Camaro and it's supposed to be making 502 hp. It's the best upgrade I've done to my '69 yet. When you open the hood everyone sees my ho-hum 351W, little do they know i'm packing big block power. ::
FOr the cleveland stroker I put in my 65
I added 620 coils for the weight
5 leafs and under rider track bars for the rear and axle wrap prevention
and the most important...2 front torque boxes which the 65-6 don't ahve.
1 1/4 front sway bar
3/4 rear sway bar
Disc brakes to stop
