Btw... Here's the 661 idling at 850 rpms.
We swapped it because the low compression was very hard starting. Sounded great when we got it running, revved like a beast. If we just used 9.5:1 pistons...
Another option was to keep the cam with a 4 or more degrees advanced crank gear. That would've increase the static and cranking pressure. Oh well. Hind sight 20/20.
