351 Windsor bored/stroked to 427? Or 460 de-stroked?

[250r'en +TCB]

Has anybody ever done this or know anyone that has? I have been trying to research this but you can't find much on things like performance and reliabilty factors........ I am considering building up a 65, 66 or 67 mustang (whichever deal pops up first) and using the 427 with a 5 speed. I have a LOT of reasearch ahead of me before I start buying and assembling, so any input you guys have on the project like do's and don't's are aprechiated.

For right now I'm concentrating one the drivetrain. I need to know if taking a 351 Windsor and punching it out to a 427 is worth doing, in other words, am I going to have a time bomb under the hood? It's not going to be a dragster engine or anything like that, but I will be demanding some performance from it of coarse!!! I have been known to put my foot to the floor every now and then I'm not looking for a ton of low end like your typical muscle car, concentrating on mid-range power but with good bottom-end as well.

Lastly does anybody have any machine shops they would recomend for the job in New England???

Thanks guys!!! -Devin

I have a friend that was going to go with a 427 from a 351 and was talked out of it by an engine builder in Alabama. They guy said he could build it, but made some other recommendations. My friend was looking at 800-1000 HP with a ProCharger. So the 427 wasn't the best option for him. He bought a complete engine from the builder in AL for about 13k that dynoed at a lil over 800 HP on pump gas and a lil over 1000 on racing fuel.

I wish I could remember the builder's name. Apparently, he is a very popular builder of Ford engines.

Good luck with whatever you decide. I'm sure it will be a money pit. Hope you have deep pockets.

Im no gear head, but know a little. If your not looking to build an all out dragster, just build the heck out of the 351 as it sits.

If it were me, I would get a stroker kit, work the heads, get some good pistons and manifolds, new ignition, ect. ect. and call it a day. That work should leave you sitting real pretty.

You dont need a 427 make serious power! If you did take the 351 and stoke it out, you would have plenty of all around power!

Like a 3-wheeler, only bigger!!!!

Yeah I'm not going to be supercharging it or anything that extreme!!! Just alluminum heads/manifold and a decent carb will do....

The reason I want a 427 is because they are famous for putting out high RPM's, but still having good torque (after all it is 427ci ) But if I find enough road bumps along the way I will call it off.....

Why not just buy a 460 or 429cj?

Are you sure the stroker 427 is the famous one, or are you confusing it with the original 427 FE from the 60s? The stroker motor isn't really a high RPM engine considering it is undersquare (bore vs. stroke). Most 427 stroker kits are for a 4.030 bore and 4.170 stroke, whereas the old-school 427 had a 4.232/3.784 bore and stroke. Plus, the strokers are built around a 6.200 inch rod, which yields a 1.487 rod-to-stroke ratio. The 427 FE has a r-t-s- ratio of 1.715, much closer to the ideal of 1.750. What that all means is that if you twist a stroker too hard for too long, the thrust faces of the pistons and the bores will suffer because the leverage seen by each is much greater than that of an FE given the same RPM and degrees of crank rotation.

Should you build a 427? Sure, why not? They're awesome engines and they make a lot of torque (and consequently a lot of horsepower). If you plan on driving it on the street, build it for bottom-to-mid power as there really is no use for a high RPM beast on the street. I've got a very mild 306 in my 93 LX, and I can tell you this, Fords love to eat rice! A 427 will have a big appetite, so you'll need to feed it quite often.

That particular 427 is no RPM screamer. Just the opposite actually, from what I understand. That displacement is arrived thru an offset ground 400 modified crank and Chrysler 6 cyl rods.(If memory serves me correctly). Most Ford engine builders recommend staying at or under the 408 mark for good rod to stroke ratios. Even at that dont expect big revs. 6000rpm max without a HUGE cam.

I like the budget 408 w/ Pro-Toplines for a big torque monster motor.

[250r'en +TCB]

Yeah 69hemiGTX your right about the FE, I was confusing the two somehow Been reading so many damn websites and books latly my brain must be giving out If I studied this much in school I'd have straight A's in all my classes, not just automotive class

Is there a bigger ford block that can be punched to a 427? Or maybe de-stroke a 460ci?? That way I could get the higher RPM's!! Here's a list of Ford blocks Jegs sells: http://www.jegs.com/webapp/wcs/store...tegoryId=10719

hey, my brother in law has one in a 67 mustang, ready to roll. He had a brain tumor, is on chemo now, could use the money to pay bills. anybody interested, I can get pictures.

Ford already made a de-stroked 460 (if you wanna look at it that way). The 460 is a long stroke version of the 429.

429 - 4.360 bore, 3.590 stroke

460 - 4.360 bore, 3.850 stroke

The 460 also had a 0.022 taller deck height, so it will be slightly wider and heavier than a 429, but it doesn't make that much difference. The cool thing is that every bolt-on for a 460 will work on the 429.

[Billy Golightly]

Personally I don't see the fascination with such a high RPM v8 engine. You can make 450-500hp out of an old 460 with a set of good heads like nothing. Seriously, a 69 460 makes 365hp with the D0VE type heads and thats before you do any other tweaking. You've got torque comparable to a diesel and a hp rating potential that will satisfy any street need...I just don't see the point in going through all the extra work just to make less power but more RPM thats going to make it more likely to fling something apart? I dunno. Hell just get a cummins 5.9 with a couple plugins and be done :P

i got a block for you.perfect for your applicatiion.it's a 97 351 roler cam block.it's stamped f4te,good blocks,and hard to find i've been told.we were gonna build a 408,with afr 205's,and a super victor intake.big power combo.but it's all went to the backburner now,and this block is for sale.lmk if you want it
