It'll piss 150 on 40's, assume they are 34mm chokes/venturis ?, you'll be looking nearer 165-170.
With a fast road cam, the only thing you will need to watch for is coil binding on valve springs and make sure you get/use the extra long posts, otherwise they can rip the ball studs out the head, try to get long pad followers, and if you can get your cam reprofiled, as it has already been work hardened due to age/use, I have never in 25+ years had a reprofile fail but have a few new cams.
The amount to take off the flywheel for your car is as much as is safe, not sure the weight of a pinto f wheel, a cossie one was 8.9KG, this was machined down to 6.6KG, as it's a cossie one I didn't slot it, but you could for yours without problem.
You will have to sort out a different ignition system, I would go back to clockwork, but with hall sensor trigger, that way easy to adjust advance retard curves diy, takes a days messing but easy, to get a lot better than a stock iggy curve, the ultimate would be a mappable system, but depends on budget.
A 1" deep manifold will be interesting, tuned length on carbs esp make or break a engine, and I expect this is way way to short by a long way, and will cause problems with some set ups.
Just make sure you use some decent filters.
I would use a felpro blue HG, never had one go pop myself, despite the abuse!!
The pinto is a ace lump, as is the X flow 1600 etc and evenb better the 2L X flow, yummy.
