I am replacing my stock timing chain (162,000) with a comp cams true roller chain and have a few questions. 1) do I still need to use the timing chain tensioner? 2) While I am in that far I am also replacing the cam (comp cc67234-4) the lifters, pushrods and valve springs and upgrading to a high volume front cover, does anyone have experience with this cam? Also I am thinking about purchasing a 200 amp alternator, would this still require the use of a volt booster to maintain adequate voltage to a larger fuel pump I.E. walbor 340. Any tips or advice would be appreciated
