Should I change my lifters, pushrods and springs?

I was looking in Jegs and the lifters cost 170.00
pushrods are another 94.00
springs another 45,

So this 'cheap' mod is now looking like a $365

 

Leave the lifters and pushrods. Just change the springs.

 

The way I look at it, the question is whether you plan on keeping this engine around a while or trashing it while you wait to replace it... I haven't found any reason to replace the lifters, but I plan on at least taking a close look at the old pushrods (maybe just replacing all of 'em, can't hurt). Springs, I'm gonna replace with stronger ones when I do my cam swap in a couple months. I'm also going to replace my valve stem seals and timing chain/gears.

You could do the swap w/o any of this and just replace gaskets, coolant, and oil, but it's a good opportunity to do at least some of the above and extend your valvetrain's life a bit... it would suck to have to deal with something deeper down wearing out soon after you did all that tho!

 

You can do a lot better than the stock lifters, but again as stated above it all depends on how far you want to take the engine. The stock lifters and pushrods will be fine. You can even re-use your valve springs but I recommend you change them if you are anywhere above 100k miles.

 

I reused my stock lifters, push rods, and springs and haven't had any problems yet.

 

What is the new timing chain for? What's that supposed to help with (other than durability) I noticed that Dynogear? has one that's a true-roller and CAN give and extra 10 horse from eliminating chain stretch. Now, I figure this is probably for the big boys, but would it matter that much to get a new chain?

It keeps your valve timing in closer sequence with your pistons. Your car will run better all around.

 

That's what it "helps" with. Broken chain = verybad news for engine, may as well play it safe.

10hp from a timing chain? Maybe if your chain is streched and your timing has been a bit off b/c of this and you fixed it, but not because it'll be any improvement over a properly functioning timing chain...

 

I reused everything when I did my Melling Cam. Even the springs have held up since April of 2000.

 

Just out of curiosty, would '94 LT1 lifters work with the 305 TBI?
with a '97 Camaro SS LT1 cam?

 

Thanks for the help guys. I guess I am gonna go ahead and just get a new chain too. What the hell, right? Besides, I've got around 120,000 miles on, and I'm sure it won't hurt anything.

The lifters should work. Same block, same roller stuff
