I can have a free ls3 cam from a friend that I would like to stab in my budget LQ4 6.0L engine. I know the cam does not have the reluctor on the back to work with the GenIII engine but Can I install a Gen IV timing cover and a 1X cam gear to make it work? I have not seen a single bolt style cam gear with a 1X reluctor only 3 bolt gears. It would be a good and reasonably inexpensive upgrade from the tiny cam in the early LQ4. The engine will be going in my 55 chevy with a 4 speed stick. I think the cam specs will work nicely with what I have in mind for mods. Any help would be great. Thanks.

An LS2 conversion is probably what you need to do hear.

^^^yep, you need the front cover, LS2 sensor, and the correct sprocket. Then you must extend the sensor wiring.

How is an LS2 conversion going to help him install a single bolt cam in his Gen3 block? What he's wanting is a single bolt cam gear, with a 1x reluctor. Such a part, to the best of my knowledge, has not been made. If it has, it has not been marketed much if at all.

No other way to run a single bolt cam except to run a single bolt sprocket which would move the cam pick-up to the front of the engine. Which may prove way more pricey then its worth. The cam he is speaking of has no rear cam pickup, any other way you think he could do it?

You're missing it...there has never been a GM vehicle made with a 1X reluctor and single bolt configuration. Any single bolt gear is 4X.

Obviously it'll have to be like all gen4 with the cam sensor up front....the issue is the sprocket doesn't exist.

Can a 1x sprocket be modified for single bolt usage...?

avmechanic

Yes. That is exactly why I was asking the question. I have only seen 4x cam gears for single bolt cams.


I was looking at a 3 bolt 1x cam gear and thinking I might just Tig weld up the bolt holes and enlarge the center hole on the lathe to fit the gear on a single hole cam. I think it could work. I was hoping by chance that something was available.
I have to check my friends stash of take off parts. I am wondering if he might have a LS2 cam stashed away in his stuff. It would simplify things. Anybody know the Cam specs for a LS2 and a LS3 to compare?

Pretty sure a stock LS3 cam is similar in specs to the old Gen 4 Z06 cams that were in the 405 hp spec'd LS6s.

From what I've read:
2001 LS6: 204/211 116.0 -2.0 .525/.525
2002 LS6: 204/218 117.5 -2.5 .551/.547
2005 LS2: 204/211 116.0 -2.0 .525./525
2008 LS3: 204/211 117.5 -2.5 .551/.525

They are close enough that it he had one it'd be a no-brainer to run that instead. But he got this one for next to nothing and is asking for help getting it running.

I don't think that the time and money in parts would be more cost efficient than just buying the correct cam....

LS2 single bolt sprocket wont work?

Sales2@Texas-speed

No LS2 with a single bolt ever has the 1X signal he needs. They were all 4X.

joecar

3 bolt sprockets came in 1x or 4x... and also in 0x.
1 bolt sprockets came in 4x only.

Might also look into putting beads of weld between the two larger raised timing pads and the closer small one, then milling out the lone small one. Also should check the orientation to be sure it's the same.

Thanks for the info guys. It was just food for thought. I was attempting to save some bucks that I don't have. Sometimes doing stuff on a budget or trying to use something that is free or cheap can cost more in the end. Just trying to research the option. There always seems to be used LS roller cam takeouts around to take advantage of. I just thought there maybe a option to go this route.

It is posible to use a 05 GTO 1X
uou need to machine the center whole so that the 1 bolt fits but you also need to machine the inside of the dish from because the gen 4 cam sticks out, so when you i stall it the chain dont align with the crankshaft, two step deal and thats it.
