[QUOTE=rpmextra;1589999222]Same. This couldn't be more timely (ported heads and a cam going in my ls3 in about a week)!

[QUOTE=SEVINN;1589999344]Just a little FYI unless you have the drysump LS3 which i think only comes on the grand sport, if your gonna changed the timing chain, you'll need to drop the oil pan in order to clear the pick up tubes of the pump. if you keep your oem chain, then don't remove the pump.

[QUOTE=rpmextra;1589999382]Thanks, that's good to know. I have a c5r chain going in and I hadn't seen that mentioned anywhere before.

rpmextra

[QUOTE=SEVINN;1589999395] yeah that pump is right over the cog blocking the chain. the ls7 pump and dry sump version ls3 have no pick up tube so they jusy carefully wiggle out.

Mods lets get it in our DYI sticky....

James might be worthwhile to let people know what you do for a living (in case they haven't figured it out).

Thanks Joe G
Yes for sure. I'm a auto technician that works on all makes and models but I'm passionate towards GM. I have been in the trade for about 14 yrs now. If anyone needs help mechanical help, diagnostic charts, wiring diagrams, Re&Re produces, GM catalog diagram and part No., trouble code diagnostics, I can be of help. just PM me and I will try my best.

Did you mention to put locktite on the cam bolts?

I've seen those back out on more than one build and it ruins the engine. I meant to ask earlier when I was reading but got side tracked.

rpmextra

Good point Joe G, no it looks like didn't include that but yes use loctite on the cam bolts and the retainer plate for sure.

Wow, awesome job! While already having the cam and heads done, Im going to use this to get to the back of the intake and replace the vacuum line. Thank You.

What a great post! So much info! Thank you very much for it.

rpmextra

Thank you .
In that case, I think you can get away from from disconnecting the fuel line. Pull the rail and swing it over. If you have stock rails that is. I had mine done and running and the oil pressure sender failed. I was so worried cause I thought something was serious at first. Sender was oem with 30000 on it so didn't expect to to fail plus I just had the engine apart. A little panic for sure. Pulled the intake and did a little diagnosis and had relief lol

rpmextra

Thank you and you're welcome

I do have stock rails and from what I've read I don't need it completely off, just moved a little. Little project for weekend, thanks again.

rpmextra

pulling the intake is very quick. should be a breeze for you. almost tempting to throw an intake on there if you don't have one already

Joe_G

I've swapped a ton of intakes and never removed the fuel line. I just set a towel on the windshield and flip the fuel rail over onto the towel.

rpmextra

Even at that JoeG he just needs to swap a vacuum line from the rear of the intake. I'd just pull it up, and forward towards the front of the car. Only need a bit of room. The towel is a great to keep it tidy

I went all in with heads, cam, headers, intake exhaust etc., had all the work done, but this I can handle lol
