Rebuilding my motor, got a new cam and all so gonna need new timing equipment. is there a better option than the 350 dollar gm replacement?

 

Need more info. What year? What car? What water pump (electric or stock)? All things to consider for a proper answer.

 

1995 firebird formula, stock water pump.

 

Well you can upgrade to a double roller timing set, but that would require the use of an EWP and a '96-'97 crank hub and balancer.

 

i planned to keep the WP i got and dont really wanna buy a hub and balencer, is there a diff set up i can go to thatll work ont he stock lt1, or do i have to buy the full gm set, or buy just a new chain?

 

Never buy just a chain.
You can get a LT4 HD timing set. Otherwise just get the OEM timing set.

 

u got part nums for em, and which would u reccommend? going 355 with cc503 cam and supporting mods.

 

LT4 extreme duty timing set: 12370835

LT1 crank sprocket: 10128346
LT1 cam sprocket ('95-'97): 10206039
chain: 10128485

 

i have a problem/? on this subject. we had my block align bored and now the new timing chain is too loose. another off the shelf one will be the same. so wat do i do? sorry if im hijacking didnt wanna make a new post and i tried to wait till you got an answer

 

not seeing the cam sproket when i enter the part num, get these from sum? found everything but that.

 

That depends on your definition of too loose. It is normal to have some slack in the timing chain. Take a straight edge across the two gears and measure the amount the chain can be pulled away from the straight edge. I think somethig like 1/4 is acceptable, but you'd have to research that.

 

ok. thanks. if its more then that?

 

Find out what it is and post your results.

 

Cloyes makes timing chain set specifically for blocks that have been align honed/bored. You'd have to check to see if they offer one for your particular engine.

Several weeks ago I did a heads and cam swap on my son's 96 LT1 with 120K miles and was amazed at how little wear his timing chain had. The new timing chain set was no tighter than the one I removed.

After finishing the work on his car, I read on another Forum how well LT1 chains hold up in what many consider as high mileage engines. My son's was a perfect example.

Had I know before I bought the new one, I would have skipped buying it.

Rollmaster makes sets for line bored applications, but you won't be able to run the stock water pump with it. They don't make a stock replacement LT1 set.
