Fe vs 385 ?

Post  boker on May 18th 2013, 12:41 am

I am building a 1964 f-100 , I plan on going with a dove headed 460 , my two brothers are big fe fans , for good reason . He has a 1975 ford 3/4 4x4 that smokes most street strip 5.0 mustangs . I was just wondering has anyone ever done a , honest side by side 390ish vs 460 with a basically same engine specs , ?? We all know the 460 would be on top but what I am wondering is by how much ??

I own both (429 and a 390)
Pros for the FE that make it better than a 385:
1. Little bit lighter with an aluminum intake
2. They looks SO much cooler. Nothing looks better than an FE with pentroof valve covers an an oval aircleaner
3. Pretty stout in stock form (with the exception of some smog units)

Pros for the 385 engine
1. Can be made freaking huge, a 390 can be made into a 445, but a 429 can hit 100ci larger on average
2. Nearly all 385 heads can be made to flow a substantial amount more than the equivalent FE heads
3. The aftermarket has continued to support 385's. There is plenty of stuff for the FE, but it is generally more expensive, and the development hasn't had the r&d put into it like the 385's.
4. Fe's require a good bit more specific knowledge to install and run.
5. 385's have a massive bore compared to an FE. a 429 has over .100 larger bore than even the FE's 427. Obviously, you can have larger valves etc etc on account of this
6. 429/460 block = $150-$300 427 block= $2000


In the end I love them both... if I had the money, I'd strictly be into the FE's. my 76 F100 has a 390 and it is an awesome engine. Runs hard enough for a daily driver and gets 14mpg doing it. My 63.5 Galaxie has a 429. I'd have loved to had a huge 427ci FE in it, but I simply don't have the $10k needed to get there, so i went with the cheap power.

Good info , I was looking at the ports on a set of eldbrock 390 heads 170cc ???? My 5.0 had bigger ports than that , looks like they would've went a little bigger ???

You cannot compare ports between different types of heads by looking at runner volume. Part of what usually is the head is the intake on an FE. There are some real FE power houses out there, but gets expensive in a hurry. FE is easier to shoe horn into some cars and tend to be lighter than a 385 series. For a pickup those things don't matter too much. The 385 series is just less expensive to build until you get into all the race and exotic stuff then it is about all the same - expensive Laughing

Yeah, dont' accept a challenge to race a hot FE Razz

Honestly the 445 stroker kit made an easy 500hp FE possible. Up to that point I'd say the engine choice is a wash... want to hit over 600 + hp? the 385 is cheaper/easier simply due to being able to use a factory/junkyard block.

Thanks .. I hate to admit it but I am kinda starting to then to the fe side . I am not out to build the fast street /strip truck , a fe would be more at home in a 64 than a 385 , it be a little different to stick wirh fe

I have seen a lot of engines of all kinfds and I have yet to see ANY Ford FE engine making anywhere near 1,000 horsepower NA no matter how much money gets spent.

Guess you don't understand how Blair Patrick made 900+ HP with an FE?

You better stay off the FE forum. Those guys are pretty serious about those boat anchors Laughing

At what cost would be my question. You could do 1000 hp on a 385 series engine for a bunch less money, at least in my experience... Idea
I don't have a dog in this fight, spend your money as you wish. It just seems you'd get more bang for your buck with the 385 series. Jmho...worth exactly what it cost you Exclamation Laughing

Not saying the FE engine is better but there are FE engines making close to 1000 n/a hp . The FE is expensive to build and very under estimated. Just my two cents!

Blair Patrick's FE 506 cid!
:



Photo quality of the dyno sheet is poor because it was taken with Blair's cell phone camera. I have never seen an 800 lb-ft FE except for my big SOHC, and that engine was 585 cubic inches. This engine is only 506 cubic inches. That is a very, very impressive torque number. And the horsepower peak of 911 HP from 6400 to 6600 RPM is also really impressive.

I spoke with Blair on the phone tonight for a while about this engine. Apparently it is basically one of his Super Stock FEs, but with more cubic inches, less compression, and a smaller cam. His normal 427-based super stock engines turn to 9000 RPM to make this kind of horsepower. Compression ratio on this engine is 13:1, and the cam is a 270@ .050" duration cam with about .700" lift. The idea behind the engine is that the reciprocating assembly and cam can be changed and the engine will turn into a legal super stocker. The heads are Blair's pro-port Edelbrock heads, and the intake is a tunnel ram style intake with two 715cfm Holleys. Blair pointed out that the heads and intake were ported and tuned together on his flow bench, to really optimize the combination.

That's about all I know at the moment, but I'm sure we'll hear more in the coming days...
