The V8 Owners Forum -

I have the complete system off a Griff, the ones that go forward expand and then go to the rear.

After some rough measurements they seem like they would fit my Tomcat with some mods to the car.

I was thinking that with the Griff manifolds i would cut down on the heat transmitted into the cabin as my left leg is approximately 30mm from the off side manifold!!!!!

However, i currently use Hedman Headers and i wondered if the TVR manifolds would loose low end torque?????

I am running a 4.6 with V8D St3 heads and an MC1 cam and soon twin plenum inlet and MSnExtra.

I would't use the TVR manifolds as the primarys are too short,I bought some aftermarket ACT manifolds and picked up 25ftlb of torque! on my 5.5 Griff engine.
