I wanted the broad power of a 'Real' FE 427 without all the weight and heat of a big block. Works perfectly with the Tremec 5 speed and the 3.50 gears. It's got a pretty mellow hydraulic cam but it was matched to a specifically ported Twisted Wedge head and Victor Jr intake that flows really well in the .300-.500" range. Mid lift flow is critical for broad torque and if done right can make more average torque and power than a bigger cam with peak lift flow heads.

I realize I replied to this 15 Years ago and I'm happy to tell you my 427 Stroker Windsor is still going strong after a few thousand trouble free street miles.

IMO having good cylinder heads and a mild compression and cam (my motor is 10:1 and have 232/237@.050 duration and .515/.515 lift) is the key, don't over-compress and overcam it and you'll be very happy.

The larger port window 11R Trick flow twisted wedges (mine are actually the smaller original TW's but max ported to 11R flow rates) and a ported victor Jr with a well-tuned 800 Edelbrock AVS has a nice choppy idle (10-12" Vacuum @ 900rpm) with a Tremec 5 speed and 3.50 gears makes for wall-to-wall 'Big Block' torque and easy 2000-ish RPM highway cruising. i can't be happier with the way mine runs, you can roll out on the big torque very tractably or stab it harder and haze and fish tail the tires at will all you want.

Sure you can do this as well with a 390-410" Windsor just as easily but for me i wanted the "proper" 427 (which was really only 425 from the factory) in my ride.

tony you can get really close w/4.100crank/4.040bore&6inch rods comes out t be 423cid & the rod ratio is not to bad.with afr 205 heads you can get 530hp w/576lift cam

Tony,

I don't really know, but theres a fellow in Dawsonville, Ernie Elliott, who does. They say he's pretty good with Fords.

Guys,
I think Tony Radford has probably made his decision already. His initial request for input was posted in April, 2003. But it's still good to hear this kind of talk.
I agree that using a Dart or similar racing block is the safest way to take a 351 all the way out to 427.

427 to 460 cubic inch World blocks and heads or complete crate engines.
No issues. Up to 600 HP for 11K.
It's an alternative to consider,

Yes, Tony did it, and I saw his car a couple of weeks ago at the Unique 2006 Homecoming event. As I recall, SA did the conversion. He drove it down to Gadsden and it ran like a champ

As many of you know, I did pull the trigger on a 427 stroker upgrade. That was about 12K miles ago. I've been just as tough on this engine as I was on my previous non-stroked Windsor, only now she's a real "neck-snapper". I disagree with comments regarding the dangers of punching a stock block out to 427 cubes. You just have to select the right parts (which Bill Parham did). I've met a number of folks who are running 427 SBs on stock blocks.

The "proper" 427 would have been an FE.

Building a 427ci Windsor doesn't make it any more original, nor does trying to disguise it as an FE by putting valve cover adapters on it. It blows my mind the lengths that people will go to, in order to make things look like something they're not.

An all-iron FE may be heavier, but they certainly didn't have any issues with weight back in the day.

The "heat of a big block" is a wives' tale. Why would a 427ci FE put out more heat than a 427ci SBF?

Well being the Thread topic is '427 Windsor stroker' it's what I replied to.

This is all my opinion only:

The Heat of an FE would be more in reference to its larger proportions which put the engine in closer proximity to the footboxes and Firewall, not related to its BTU output for a given HP.

for a street Cobra Replica the lighter weight of the smallblock somewhat offsets the typically heavier fiberglass replica bodyweight vs a factory Cobra aluminum skin, an FE only makes a heavier replica even heavier all else being equal.

As for the Valve covers on my motor? They were gifted to me (someone assumed it was an FE 427) so I used them.

Im just stating I am very happy with my motor and the car's reliability and performance. Period.

Because, just like me, it's carrying a little extra weight. LOL
