is there usually enough PTV clearance in a stock 5.3 to run a .600
lift cam with a short dur. ? 224 deg. dished pistons. 799 heads
this is a running motor in truck that i want to put the cam in.

 

I ran a 223 226 610 605 110+4 cam in my old L33 with flat tops and 799s with no problems at all

 

219/223 607/610 112+2 in a LC9 with flat tops and 799's

 

i think its safer to run the cam stright up.

 

the cam has a 105 int C/L with 114 lobe sep and it's a VVT cam
forgot to put that info in, sorry

 

i think thats too much lift for a vvt cam i was checking that out when i first got my truck a couple years ago. one of the phaser limiters is safer i think the older version. check with tsp im thinkin 570 max on the 5.3 with flat tops and #799s. let me know thats probably in my future to igot the 1.8 yella terras. i was gonna get a cusyom ground vvt from sdpc with about 530 lift to ba safe. rite now i got the dod/vvt 500 lift comp cam with my 1.8s its about 536 lift.

 

I have .556/.568 right now, going to put the 1.8 rockers on it.
moving it to .589/.602

 

guess youl find out at about 6200 rpms.
