Is the 390 high performance exhaust the same as 428 Cobra?

Although the 390 High Performance and 428 Cobra Jet exhaust manifolds may look the same, they are not the same casting. What it comes to factory cast-iron exhaust headers, Ford had it all over the competition with these early Galaxie 406/427 iron bananas. Found this pair at John Vermeersch’s Total Performance shop in Detroit, Michigan.

What kind of exhaust manifold does a Ford truck have?

Ford Trucks: 1965-’83 300 6-cylinder w/o thermactor emission; 1981-’85 351W both sides interchange; 1980-’85 302 left and right interchange; 1968-’76 360/390 Truck manifolds interchange.

When do exhaust manifolds interchange in a Pontiac?

Pontiac: 1941-’54 8-cylinder manifolds interchange; 1964-’68 V-8 manifolds interchange, with driver’s side continuing to 1972; 1969-’74 V-8 passenger side manifold; 1971-’74 V-8 driver’s side manifold. Obviously, these are not all the exhaust manifold interchanges that are possible.

Can a 427 exhaust manifold fit a Galaxie?

Only the 406 and 427 High Performance exhaust manifolds flowed well, thanks to their cast-iron header design. The thing is, these huge “bananas” don’t always fit every application. They fit a Galaxie or Marauder well, which is what they were designed for. But they won’t always fit a Mustang or Cougar due to space limitations.

Do you need an exhaust rocker on a Ford FE?

Dove FE heavyduty rocker shafts are more durable than stock parts, but should still be used with an end-support system. On an FE the end exhaust rocker is unsupported and prone to flex. An end stand provides a measure of added support and prevents failure. The FE is unique because of the pushrod arrangement.

Can a dove Fe be used as an exhaust rocker?

These FE rockers are slideon replacements for adjustable or non-adjustable factory parts. Dove FE heavyduty rocker shafts are more durable than stock parts, but should still be used with an end-support system. On an FE the end exhaust rocker is unsupported and prone to flex.

When did the Ford 390 engine come out?

Although Ford’s 390 cubic inch eight-cylinder engine was first produced for the 1961 production year, it was not a popular engine choice until the mid-1960s. The 390 is perhaps most notable for being the first big-block engine installed in the Mustang in 1967, although it was replaced by the 428 engine in the middle of the following year.

Where can I get rocker arms for my Ford?

Can a 390 flywheel be used on a 460?

You can use a 390 flywheel (I did) if you have a pre-75 early internally balanced 460. Two pilot bushings (bearings) can be used, the large one that fits in the very back of the crank or I used a 5.0 Mustang pilot bearing that will fit in the crank about 3/4″ deeper to allow you to use a small block transmission.

Can a 400cu engine be swapped for a 460?

Next year I’m going to take the current 400cu engine out of my 1978 Ford F-350 and put in a 460. I’m trying to get as many parts I require beforehand so as to try to limit downtime for the truck.

Do you need an exhaust system for a big block Ford?

Exhaust systems remain an area of interchange with the most performance potential. Ford big-blocks are no exception to this time-proven rule. If restoring to stock, then your answer is clear. You need stock exhaust manifolds and a stock exhaust system.

Is it possible to interchange an exhaust manifold?

Obviously, these are not all the exhaust manifold interchanges that are possible. Other manifolds will fit with adaptations to the exhaust or the addition of accessory brackets that may be missing from an earlier year manifold.

How much horsepower does a new exhaust system add?

Here’s how you can figure out what to expect: Horsepower is calculated by multiplying torque by RPM. Therefore, if a new exhaust system adds just 10 lb-ft of torque at 5,000 RPM, that will result in a horsepower increase of 9.5 hp.

Is the 390 high performance exhaust the same as 428 Cobra?
