Early LA 360 Blocks

well you seem to already have all the answers so do what you want.

Something intellegent, preferably from actual hands on experience, that a more experienced engine builder than myself would know. But thank you for your ingenious answer to my rlr cam ?

MRL--Thank you. That does help. Is there enough material in the early block to modify it to magnum oiling capacity? The mag appears to have larger main web supports also, is this due to difference in metal strength/composition vs the early? And are the lower cyls less likely to crack in the early block in higher hp stroker apps without block filler vs the mags?
