Starting a new post since a lot changed since I started this one last year.

Need cam advice based on actual availability due to current cam shortage from lack of cores.
Have:
70 GTO
5 speed
400 block
4.25" stroke Eagle crank
#12 heads reworked by Butler with Crower 68404 springs and 7/16 studs. All new Ferrea valves, etc. 72 cc

Plan to have block done 0.035 over with Icon forged 30 cc dished pistons. ~9.5:1 compression. Forged rods will also be purchased.

The heads limit power as they are unported, but that is OK. They are original and I plan to keep them as is. The springs limit lift to 0.520. Budget calls for HFT.

Looking at what's out there in stock, there is the Melling SPC-8 041 Ram Air IV clone that I could use with 1.65 rockers but will I need to elongate pushrod holes?

The Lunati 704 has a little more than 0.520 lift and probably wants a little more spring pressure than the 68404 springs provide to control its aggressive ramps.

I am willing to sacrifice a little power for reliability/not modifying the heads further.

Would you do either one of the above or wait on another cam option in 6 months or more?
