The ( 2005 ) was the first model year that the Ford Mustang Gt 4.6 L had the 3 valve ( 3V ) heads
about 50 hp
There should be no difference The difference between the two are the different set of heads and intake used on the 1999 that was not used on the 1997.
there is no adapter. vortec heads were cut at a diffrent slope than standard sbc heads. you can swap the heads on the 78 350 for vortech heads or get a multipoint fuel injection intake for a 85 - 95 350. you can get the intake from summitracing.com You will have to swap the heads and the intake
96-98 Mustangs with the 4.6 Liter have 215 Horsepower, the 99-04 Mustangs with the 4.6 Liter have 260 because of newer better flowing heads than the previous body configuration. If desired a 96-98 Mustang can be fitted with heads cams and intake off of a newer Mustang to net a higher HP rating and higher compression to gain a bit more.
A 350 SBC with aluminum heads and intake would weigh approximately 450-500 lbs. Adding carburetor, headers, alternator, water pump, and other accessories would increase the weight to around 500-550 lbs.
Intake valves are in the cylinder heads.
It is under the intake, between the heads.It is under the intake, between the heads.
In 1996 Ford converted the Mustang GT base engine from a 5.0 liter pushrod engine to a 4.6 liter modular engine "overhead cam design". This was Ford's first go with the modular engine and the new 4.6 liter was less than pleasing with only 225 hp to the wheels. This version of the 4.6 liter 2v engine was used in the GT's until 1999 when Ford released the 4.6 liter power improved "p.i." engine, thus deeming the previous 4.6 liter 2v engine "non p.i." The improvements consisted of larger and straighter intake runners "the cambers through which air is delivered to the combustion chamber" in the heads, larger intake manifold runners "the chambers that deliver the air to the heads" and larger intake and exhaust valves. With these improvements of head and intake manifold air flow as well as exhaust flow the P.I. engine yielded an additional 35 hp to the wheels laying down a respectable 260 hp. Other than these improvements the engines are identical, leaving the option for the 1996-98 Mustang GT owners to swap these heads and intake to their Mustangs, which is often referred to as a "P.I. swap". (NOTE: The P.I. swap will raise the compression ratio of the non P.I. engine to 10:1, making forced induction almost impossible without running a higher octane fuel. If you plan to do this to you're 1996-98 Mustang GT and use a supercharger or turbo it'd be in your best interest to use a dish style piston.)
will 1995 Chevrolet 350 intake fit a 1997 vortec heads
the fastest way to tell is if the center intake bolts are not there.the vortec heads that everyone wants for performance have no center intake bolts.
Into the heads only.
