gonna go ahead and do a cam swap, while im in there do most guys upgrade the timing chain and oil pump?

 

How many miles are on it? Some do some don't depends on how worn they are. Alot of the time when putting the oil pump back on the O ring gets pinched and causes oil pressure issues.

 

the truck has 145,000 kms so like 90,000 miles

 

Yeah I'd do both!

 

My chain was sloppy at 73K on the motor I'm working on. Ordered a HD single row chain from one of the sponsors here.

 

ls2 chain and an ls6 pump where reccomended to me.

 

If it's an average build that won't be spinning to the moon, you'll be fine with an "LS2" timing chain, which can be obtained from one of our sponsors such as SDPC (where I got mine, awesome customer service). Don't go crazy on the oil pump, the factory pump is more than adequate, no need to break the bank. I'd either get a factory replacement or check Lingenfelter for their GENIII oil pump, last time I checked they had the best price, pump may have been ported and polished (unnecessary IMO, but it can't hurt), but I can't remember.

 

When I swapped mine I did the LS2 chain and Melling oil pump.

 

ok thanks guys, ya its not a crazy cam just something thats goin to work well with the lq9 and my setup.

 

im leaving the stock oil pump and doing the ls2 chain when i do my swap hopefully soon at 64xxx. dont feel i need a new oil pump yet, i could be wrong though
