Cam and timing set install question

Looks and sounds like a great combo.
I once had the next bigger cam in my 360, 223/230/110 and it was and still would be my favorite cam, except it dropped lobes one morning. Like you say "crazy low-end power."
When i bought that cam early 90s the split pattern 268 wasnt around and i had 3.23s i knew nothing of the .903 lifters i debated going with the comp 270h but with 3.23s i pussed out that cam only has 1 more degree ica that would have been a nice cam with the 3.91s
with a freshened short block id prolly be over 170 psi highest stock rated 340 was 175 i guess i got lucky
