If you’re looking for the latest in technology to put under the hood of a street rod here it is: Ford’s new 5.0L Ti-VCT.
Unlike most activities that fall under the motorsports heading, street rodding doesn’t have a rulebook to follow; there are no clearly defined regulations. About the time our hobby seems to be growing in one direction it branches off in another. From our vantage point that’s what keeps it interesting and why it continues to grow. Case in point—it wasn’t all that long ago that one of street rodding’s new directions was putting a Ford engine in a Ford, evidently a Bow Tie powerplant in place of one wearing a Blue Oval had run its course with some. So, despite the fact that the venerable GM small-block V-8 fit an early Ford like it was made to replace a Flathead, in an effort to be different more and more builders began to put Fords in Fords, but there may be a change in how that is done as well.

It took some work, but we installed a 5.0L Ti-VCT, aka a Coyote, where a pushrod 302 once resided.
A number of years ago we did a series called the 5.0/’41 and showed what it took to put a small-block Ford in an early Ford chassis. The lesson we learned was simple enough; there was a real good reason to use a Chevy. In most cases the Ford’s oil pan created clearance problems, which often required either crossmember or firewall modifications; a remote oil filter was usually necessary and connecting the steering shaft to the rack-and-pinion on an IRS could require two hands full of U-joints; finally a late-style OEM front cover and pulley combination, or an aftermarket compact front drive system was needed to reduce the engine’s overall length. In short it took some extra effort to put a Ford in a Ford, but for many Street Rodders being different was worth it.
The initial test-fit was a...
The initial test-fit was a little disappointing; to get the engine down and to the rear where it should be was going to require firewall surgery.
When Ford introduced the new 302 Coyote V-8 engine or the 5.0L Ti-VCT to use their nomenclature, we were impressed at the technology it represented. The all-aluminum V-8 produces 412 hp at 6,500 rpm and 390 lb-ft of torque at 4,250 rpm and in the new Mustang it is rated at 17/26 mpg city/highway with a six-speed manual and 18/25 with the automatic. Everything about the new engine was appealing but our first thought was the lack of availability would mean it would be some time until one showed up in a street rod. However it seems that what we’re up to hasn’t escaped the notice of corporate America and more than a few folks at Ford have taken exception to the competition’s engines, showing up in their cars no matter how long ago they came down the assembly line. As a result Ford Racing Performance Parts has included the Coyote in their crate motor program as we outlined in the May issue of SRM. With the availability issue of the new engines resolved our next question was, “What’s involved in getting a Coyote into an early Ford engine compartment?” To answer that question we dug out the same ’41 that once housed a Windsor-based 302. Like many projects, once we were done with the Ford in a Ford series the 5.0/’41 was shoved to the side and has sat neglected while we turned our attention elsewhere.
Rather than replace the entire...
Rather than replace the entire firewall we elected to recess the portion directly behind the engine.
At first glance, installing the new 5.0L Ti-VCT looked like it would be a challenge, and the truth is it did require a few nips and tucks, like notching the Fatman front crossmember, recessing the firewall, and installing a remote oil filter adapter. Certainly there will be some extra effort involved in shoehorning one of these engines into a fat Ford engine compartment when compared with other options, but the benefits of an all-alloy four-cam V-8 with the latest technology will be worth it when it’s done. And it will definitely be different.

Following our taped outline,...

Following our taped outline, a cutoff wheel in an air grinder was used to remove a section of the firewall.

The chassis had been equipped with a Fatman Fabrications front crossmember. A test-fit indicated there was interference between it and the oil pan.

A substantial hole was necessary...

A substantial hole was necessary to house the Coyote. As the X-member had already been widened to accommodate an overdrive automatic no other modifications were necessary.
We fabricated these motor mounts from flat steel plate. Note they are different side for side (the larger plate bolts to the right side of the engine). The rubber cushions are early Ford V-8 style from Speedway Motors (PN 720-9314).

To accommodate the pan an 8-inch notch 3 inches wide by 2 inches deep was made in the crossmember. The section removed was flipped upside down and used to box the opening. The open ends will be capped.

These are the stock Ford motor mount plates. Made from aluminum and cool looking, they’re slightly too wide for use in early Ford frames.

With the crossmember notched...

With the crossmember notched and the firewall opened up the engine sits down in the chassis as it should.

The location of the oil filter...

The location of the oil filter is problematic. In our installation it interfered with the rack-and-pinion.

Ford Racing and Performance...

Ford Racing and Performance parts offers this oil filter relocation block that also accepts the oil pressure sender under PN M-6881-M50.

An inside view—the engine protrudes a little over 3 inches into the passenger compartment however there’s still plenty of legroom.

Removing the stock oil filter...

Removing the stock oil filter mount leaves plenty of room for the rack-and-pinion and steering shaft.

This is the section of firewall that was cut out. We will add a flange to it and put it back, but first we had to fill a variety of holes.

Some holes were small enough to simply close with our Lincoln MIG welder.

Before welding any holes closed the surrounding area was made flat with a hammer and dolly.

For larger holes we cut plugs from sheetmetal and welded them in place.

These copper backup plates from Eastwood are helpful when filling holes as the welding wire won’t stick to them. One is handheld, the other two have magnets to hold them in place.

A hammer and dolly were called on again to straighten the cut edge of the stock firewall. We then measured for the flange that would recess the centersection.

With all the holes plugged, the firewall section is ready to have the flange added.

To fabricate the firewall...

To fabricate the firewall flange we used a length of 16-gauge sheetmetal 6 inches wide. We don’t have a sheetmetal brake, so we used the next best thing, our drill press table with a chunk of angle iron clamped to it and made the initial bends with a body hammer.

An adjustable gauge was used...

Basically the plan was to use this strip of sheetmetal to recess the centersection of the firewall. A test-fit proved it fit close enough for welding in place.

The gauge was then used to fine-tune the bend in the flange.

An electric shear was used...

An electric shear was used to trim the filler strip to its proper width, which turned out to be 3-3/4 inches.

We tacked the filler strip...

We tacked the filler strip to the centersection of the firewall then tacked the recessed portion in place. A test-fit of the engine verified that there was plenty of room so all the pieces were welded together. We haven’t decided on a transmission yet, we’ll finish the toe and floorboards when whatever we use is in place.
