Stroking an FE -- Questions!!

-Are the Edelbrock FE heads the best available right now?
-Who's making the best weber-style induction setup for the FEs these days?

Bryon,

It seems like 482 ci or so is a pretty straightforward FE stroker combo. This sort of setup should reach 600 - 650 hp with comperable peek torque on pump gas. Webers can be very difficult to get and keep in tune. You migh consider EFI though. This can provide a similar look and should run better than any sort of carb setup if its tuned properly. Keith Kraft (on this BBS) is a good source for a setup like this. He did my 482 ci FE with and EFI setup. Keith does nice work. On heads, the Edelbrock alum heads seem to be the best starting point for performance and affordability. Many outfits including Keith will port them to improve them someone over the out of the box versions. Are you looking to build a street motor or race? What are you looking to put the FE into?

What was the price for your engine, including the EFI computer ?

Anthony,

Its probably best to go to Keith Kraft for a quote. Folks seem to prefer that pricing on Keith's work not be posted in these forums.

Does anyone build a standard bore and stroke 427 anymore. Isn't that the point replication of the original? Yes I am running a Boss but will change back to FE in the future, std of course.

If cubes are what you want the new larger crate engines will give you the thump with more reliable advances in technology.

More torque, more horse power at a useable rpm and everything outwardly appearing the same as the original? I think that sort of epitomizes what I'm looking for (one of the things anyway..) in my replica.

1985 CCX Jeff can you tell by looking at any FE motor in a car what size it is? The only way I have seen a possible size differents is how long the burnout is and how many gears are pulled. Except for the race gas in some of the cobras at shows and smelling it, they all look big in the engine compartment. For the price it takes to build a 427 cubic motor, you can add another 55 cubes and get more power at a lower RPM and have less maintainance overall. I think that we, sorry ( some of us ) That you can do more or the same with a different gearing in the rear of the car and less compression. The trade off is a lower RPM limit. IMO I don't like turning my strokers over 6,200 rpm with a 6,500 max. It's easier to change the gears in the rearend or get a double overdrive trans, then rebuild a motor. The new street Richmond 5 spd is a great gear ratio for a cobra with the 2.87 and .77 overdrive. With a set of 3.08 or 3.31 you have the best of both worlds. Add a KCR roller cam and the cars idle nasty and sound like a solid roller camshaft. In the end does it matter, when the cars look as nice as yours with the big GY tires and knockoffs. Rick L.
