Default Little 449ci FE road race engine....664 hp/614 lb-ft....

Dyno'd this one a few weeks back. Not for a Cobra, but just a testament to how efficient the new TFS heads are. They're essentially all I'm using now for aftermarket FE cylinder head packages.

This engine below was built from all new parts, including a BBM block, custom Scat 4340 crankshaft, Diamond pistons, K1 rods, one of my custom solid roller cams, and an assortment of other go-fast parts, including an Aviaid dry sump system, and T&D paired/race rockers.

'66 Galaxie road race car. It's a 3 gallon oil tank, pretty common for automotive dry sump applications.

Are these heads cut off short in the intake ports and the missing parts cast into the intake like all FE engines? The pictures make it look more like most other engine designs where the intake does not have part of the valve cover rails cast into the intake.

The intake is similar to a tunnel port look only the ports are between the valves and does not have a push rod in the center of the port.

Any light you can shed would be appreciated.

The bottom photo shows a front on shot, where you can see the intake has the valve cover rails.

It has a motor plate on it, powercoated black, so it looks funny from the front-on shot.

Yes, electric pump....

Yes, harmonic balancer, just doesn't show up in the picture that I posted because I hadn't bolted it on yet.

Dry sump is 4 stage.

Why did you go with that size engine? Is it to meet some class rules?

I like shorter strokes on engines that see higher rpms for long periods at a time. It has nothing to do with longer strokes not being able to rev, but it has a lot to do with longevity of the engine. A shorter stroke has less piston speed and a shorter stroke has less weight to throw around, so it's easier on bearings. This engine wants to live in the upper rpm range. It made 664 hp @ 7000, but was still gaining horsepower.

The owner is an older gentleman and just wanted an engine that makes plenty of power but is easy to maintain and doesn't require a lot of freshen ups.

This is a 4.350" x 3.780" combination. It's the shortest stroke that Scat would let me make on a custom 4340 crankshaft.

I think the old 391 large truck engines had steel cranks that you could turn the front down, for high performance use back in the day. Last one I saw was 15 yrs ago. Maybe they are all gone or maybe you trust new stuff more. Anyway it was a thought -- not necessarily a good one though.

You can do it that way, but you end up with thousands of dollars in them. Not only do the snouts have to be turned down, but the flywheel flanges too, in addition to converting the rod journals to BBC.

The custom Scat has undercut pendulums, gun drilled mains, scalloped flywheel flange, and only weighs about 55 lbs. Plus they make it to fit your bobweight so it doesn't require $700 worth of metal like the 391 crank can.

I see the gauge on the intake breather port. What's the purpose of that? Check crankcase pressure on the dyno? What numbers do you expect to see?

I'm just curious, never seen this before. Seems like a good idea for many reasons. Thanks

Kinda...

Not checking crankcase pressure, but crankcase vacuum. The dry sump pump pulls vacuum on the crankcase and we have to make sure it doesn't pull too much.

I have DLC coated tool steel wrist pins and coated bearings, but higher crankcase vacuum can actually do damage if it's not curbed. I try to limit it to about 12" of vacuum. This one pulled 15" out of the box because the engine is sealed up well and I had to regulate it.

I figured it was pulling vacuum, never would have guessed 15”! Very cool. Thanks for the info.

I was wondering if anyone had ever fitted a dry sump to a FE. Now here's one! Cool!


Why so much oil? My FGT tank (working backwards) probably held 8 qts.

A better question is why dry sump? The Galaxy has plenty of room for the pan. I thought the FEs were designed to tolerate the sloshing from side-side motion.

CSX3002 had a dry sump.
