1999 OLDS ALERO 3500 swap

[nixtux]

Going to get the below on Saturday from the wot-tech store. Hoping to
verify that it's the proper parts for the cam.

260, 206, 0.533, 3118

Comp 26915 Valve Springs
LS1 Valve Spring Seats .553" OD
Valve Stem Seals for LS1 Seats
3500 V6 Valves (LX9)

I'm also thinking about polishing the upper intake and maybe the timing
cover. Also what's good for engine painting? There is a lot of options
but some seems to suck so it's been difficult making a informed decision.

I would rather see you use the Comp 28986 springs and be done with it.

They don't require anything else. Uses all the stock stuff and they are just fine to .600 lift.

And you're likely best springing for the custom pushrods.

And join the slowly emerging group buy for the single roller timing chain.

Why are you buying valves?

[nixtux]

I figured change out the valves since they are lighter and it's easier to do when it's not in the car. In the process port and polish the heads.

I guess I can skip that step to get things moving. Do a more aggressive build over the winter. Probably get a different car for it though.

I've been considering the single roller timing chain. Once I finish this project I want to pickup a cradle and start a slow build doing a 4T65-E HD or a Getrag 282 and a 3500 and add a M62. Just some ideas at this point since I'm still researching what's needed and have to learn the tuning aspects before I consider anything new.

Youre putting 3500 valves in a 3500? I don't get it.

Lighter, less weight on the valvetrain was the idea. If the heads have
to come off anyway why not put on lighter parts?

At least my understanding is a lighter valvetrain is more efficient and those
valves are stock replacements that are lighter.

Waste of money if you don't need them.

[nixtux]

Fair enough, thanks. So just do the Comp Cams 26986 Valve Springs and
use the stock parts. Can't go wrong, a little extra cash for other things.

The recommended was the 26915 but I'm not an expert with this stuff so
just want to be extra safe so I don't get stuck on the side of the road
again.

"Stock replacement valves for the 3500 engine."
Those are stock 3500 valves... They are lighter than 3100/3400 valves. But if you have a 3500, then they are the same.....

If your cam won't work with the 86 springs then it wont... Best to ask Ben.

your confusing the hell out of me with this.

your getting a complete 3500 engine right. if that is true then you dont need to buy the valves from the store as your engine already has them.

whats the specs on your cam other than the gibberish you listed in the post above.

how much experience do you have with tuning a car.
