hi guys

how are you today ?

i have everthing someone need for cam install exept the cam itself

here is my mod list :

cai , LT headers . custom 3in dual exhaust with magnaflow muffler . milling oil pump
heads are 862

what do i have for supporting cam : PRC 650 dual spring kit . Chromemoly pushrods 7.4

for Timing Chain what will work great in my setup single or double ?

for the cam itself i am thinking in comp cam 281LR HR13 is to big for DD ? do you think i will face flycut with this cam ?

i will upgrade all my engine and heads bolt to ARB , i am planing on single 91mm turbo on next summer so if there is better cam outperform the 231-239 617.621 113 please give me your advise
