Yes, That's at .050. I'm not sure how MM installed it. I was going to check how it was installed and If it was installed straight up I was going to try advancing it to increase cylinder pressure. I will be pulling engine next week and get it ready to return to MM.




If your correct on your specs your @ 4* advanced installed at a 110 ICL with a 114 LSA cam with a intake duration of 283 @ .050 and a exhaust duration of 295 @ .050


Yes. Cam card reads .050 duration at 283/295 on a 114 LSA installed at 110 . Duration at .020 is 314/330.

PSO headed 632 from MM. Cracked cylinder, loose valve seats, low oil pressure, low cylinder pressure.
