fitting exhaust header on 2.0 stock 73 body
« on: January 20, 2016, 12:22:34 PM »
does anyone here have info about what needs to be done to the motor mount to fit the Schoenfeld header to a stock 73 pinto with the 2.0 engine?

does anyone have photos?

or is it possible to adapt the header by re routing the tubes to fit the stock motor mount.

Big waste of time & $$. Better fix is a 2" exhaust all the way out the rear. The header you talk about is a race car header and will hurt more than it helps. 2.0L Pintos are torque poor and a header like the one you want will take away torque till you get up in the 6000 rpm plus range. Been there / done that! For a DD, forget big exhaust / header and just in joy the very nice ride you have.
Its better to be a has-been, than a never was.

Thanks for the input...

I had forgotten about needing back pressure in the exhaust

I'm not really interested in hot rodding the car, just want to have a reliable DD with good mileage that I can pass along to my grandson some day.

The car already has 2"  exhaust and a small muffler , I put in a pertronix ign and opened up the primary jet in the carburetor.

With the stock cam it starts making power at about 2500 and pulls to about 4500 to 5000 if i push it

The car has a 3.40 rear end and 14" tires so its not a ground pounder off the line and a bit sluggish on hills in 4th so i do need more low end.

I Think ill just keep the stock manifold

Thinking about switching to an early 350 CFM hollly 2 bbl. but have had issues with the power valves in hollys before (lots of 55 fords, falcon sprint, etc)

I also have a pair of really nice SU HIF4 side drafts with all the linkage that should flow about 350  cfm and am thinking about having a manifold built for them

Back in 1980 i had a 2.0 with isky cam, mallory dual point, holly 390 4 bbl, header, 10:1 compression in a 72 capri and it ran really well, just started making good power at about 4000 when the secondaries opened and spun up to 7000 but after about a year the booster venturies kept working loose from the vibration and the power valve kept failing.

At that time I was in so cal and there were a lot of parts there for cheep money for 2.0's

Also had a stock 72 pinto that I bought new in 72 and it had all sorts of carburetion and ign problems

I'm also looking for a block to build as a spare while there are some still available.

Again thanks for the input
