George has it listed as as a substitute for the SVO A341 cam, so specs would be similar.
IF you are looking for a stockish cam with a little more, look down his list at the Crane hydraulic roller. The numbers are right where they should be to answer your description of what you want.
It looks good to me.
As far as domed pistons with the open heads, I used the TRW ones.
They had way too much compression with the closed heads without using leaded racing gas.
I swapped those heads out for the 4v open chambered heads and they STILL needed octane booster with the domed pistons. Trade them away to someone. There will be people that want them even used.
I personally think the best combination to run on the street with pump premium is the closed chamber head with the dished 72-74 pistons.
With the standard Fel-pro head gasket it will put you right around 9.7-9.8 to 1 cr and runs fine on pump premium with a fast-ish distributor curve. It pulls really nice but you need some over lap on the cam to help out which should work out well.
Something in the 50 to 60 degree overlap range which puts you right in line for the above Crane cam.
Sounds nice at idle too. Very much in an Italian Exotic period idle sound.
To go with more overlap you are going to need to deal with the poor Pantera exhaust headers. Even the GTS ones are restrictive and the ANSA mufflers are nothing but resonators that in effect work as are limiters.
A 650 carb would be better. The 750 primary bores are too big. A spread bore Holley in theory should be the carb to use but you need to figure out how to make it work, which ain't easy.
The Chevy guys just trash those things so you might find one cheap use that's almost new AND it will fit your original intake manifold.
