Wow!! Awesome engine cant wait for the details and pics!

 

Awesome John!!

 

John, let me know if you guys need any help.

 

Sure thing Chris.

We are still working on my son's 69 LS2 car and I bought a 67 project last weekend that I'm building a new 383 Stroker Roller motor for.

 

This is the Car and what coming out. It only has a couple thousand miles on it.

Man, I'm sorry to say but an LS3 isn't going to help that car any. Now if it was a 67 RS that would be another story.

 

Hey! That looks like my car! Oh it is! Can't wait John! And you're right, the engine that came out was nice, but an LS3 is awesome! Always wanted to do one and what a car to put it in!

From the outside it looks like a stock 1969 Z/28. but when you lift the hood........!!!!!! :hurray::beers:

Steve, that is going to a very nice upgrade for sure...and seeing what John can do with these cars it looks like you have all your bases covered. Are you going to leave the Corvette covers in place.....just asking?

 

Ka BAM!
:thumbsup:

 

Sweeeet

 

Dibs on the 355?

...but that LS sure looks pretty...

 

thank you thank you thank you!!
i was hoping someone was going to document a swap with all of the new swap part choices that are out!!!

 

I'll post the parts list and cost. I am using the existing TKO 5 speed. It's on it's way to liberty gears for a tune up. McLeod clutch flywheel (made to use with the small block bell housing) and hydraulic clutch master and slave conversion kit

We are using all new parts. GM Performance LS3 480 hp. GM accessory drive without AC. Holley AC bracket to accept the Sandon Compressor that was in the car from the Vintage AC install.

Dynatech swap headers that will clear the stock steering box. LS radiator with dual spal fans from a radiator shop I buy from and a Tanks Inc EFI fuel tank. I use one on my built LS7 and it works perfect. Also the quality is very nice.

 

John,

Great timing, I got the same motor and it literally just showed up today!

Couple of things:
- What computer & harness are you using?
- Holley just released all components - new oil pan just for 1st gen, mounts, Trans crossmember, and headers the tuck way up in the subframe.

Went with the GM performance kit. I think it was $1170. Includes the muscle car oil pan, wiring harness, ECM, all the senors inluding O2 sensors and MAF

Complete plug an play package specifically this LS3 so no tuning will b needed.

Based on my research it's the best bang for the buck.

I'm locating the motor in the exact same position as the 355 so the crossmember we have will work and the shifter will be in the exact same location.

 

Regarding the GM muscle car pan - I've been told the sump hangs too low.

 

I have that pan and yes hangs lower than I want. There are a couple sheet metal pans out that dont, but they are sheetmetal.

 

Update LS3 6.2L 376ci/480HP Engine Install Thread

Still getting Parts together.

I'm using Dirty Dingo Slider engine mounts. They are adjustable from 1/2" back to 2 1/2" forward.

I'm installing the LS in the same (stock) position as the 355 was so I will be able to use the existing crossmember and the shifter will be in the exact same location.

These brackets will allow me to make fine adjustments if needed to make it all work perfect.

I'll post a complete parts list soon

 

This is going to be awesome. What are the specs on the old motor?? I just put a new 350 in mine. Can't wait to fire it up

 

Old motor was a 4 bolt main 355 roller motor. 10:1 compression. Edelbrock performer rpm alum heads comp roller cam. Air gap intake. Holly DP and Hooker Procomp headers. Approx 420 hp

 

Wow john that sounds very close to my new motor. ZZ4 short block edelbrock etec 200 heads comp xr288hr cam air gap Holley dp. Hopefully it runs good:yes:

 

John, can you tell me what size tires are on this blue camaro. Thanks

 

BFG TA Radials

255/60R15 Rear
235/60R15 Front

 

I can wait for the next update, some questions already,

What bell housing? using a Hyd clutch and not the stock mech? what parts cost and photos.

It bolts right in to stock location? Great, so some motor mounts and what cross member?

Sorry just wanting to do this to my 69 and don't want to reinvent wheel when you have done it and have the bugs worked out.

Thank you so much...
JC

 

some update pics

This is the Dirty Dingo Slide Mount. Allows you to adjust the engine to any location from, 1/2" back to 2 1/2 " forward.

I'm using the SB Bell housing/scattershield that was on the 355 along with the McLeod Flywheel that is machined to work with it. I measured the engine mount on the SB and set the LS swap mount so the bell will be in the exact same location in the car as it was with the SB. This will bring the shifter up is the same location as well as no changes to the crossmember or driveshaft.

The mount will let me adjust slightly if I need to for header or other clearance. So if I need a 1/4" either way it's easy to do.

I'll be test fitting the engine into the car next to check all clearances.

Installed the front accessory package. GM without AC and the Holley AC Bracket that accepts the Sanden AC Compressor that was on the 355. The Holley Bracket is cast and looks like GM Factory

The Oil Pan is GM "Muscle Car" which is actually the Hummer H3 Pan. The Engine came with a Corvette Pan

Dynatech Headers

 

John, told you the Holley bracket was a nice piece. Give me a call when you get a chance.

 

It's nice for this build although by the time you buy the required install kit it does cost more the Kwik or Dingo which I also like

 

Had a great day yesterday.

Started off with a spirited drive in my car for inspiration then a test fit of the LS3.

Car had the 350 frame towers. (1 /1/2" frame to bolt hole center) These were too low and the pan was on the cross member.

I had anticipated this possibility and had a set of 307/327 frame mounts (2" frame to center of hole).

Set the motor in and good clearance all the way. about 1/4" pan to cross member.

The Dynatech headers have very good clearance. I'll post some pics later. I set the motor in the stock position so that the shifter, tranny cross drive shaft etc and go back as it was with the 355.

The engine could be moved 2" forward if a guy wanted too and the headers would still clear easily.

The headers hang a little lower then the Hooker Procomps we have on our other 2 LS 69s. When I install the tranny and tranny cross the rear will come up a little and we will have about 6" ground clearance. Car has 2" drop Hotctkiss on it.

Looking great John :thumbsup:, I am sure Steve is getting anxious :yes:

 

Yes I am!:yes: We dropped the engine and new tranny in this past weekend. Fit's just like John said it would! Awesome! The shifter is in the same spot as before and the driveline all matched up!

I decided to upgrade to a new TKO600 5 speed tranny. This gives me another 100 foot pounds of torque over the old one. The delay on this project was the company we sent the tranny for inspection, sat on it for nearly a month before telling us it needed a complete rebuild. I decide enough of this and opted for a new out of the box TKO600.

I'm sure when John gets time, he'll post more pic's for you guys. I'm not much of a gear head but John's painfully turning me into one! LOL!! He and another buddy of ours have taught me a lot these past few months. I was beginning to wonder if I bit off more than I can chew, but it's all coming together now and I can't wait to start her up soon! :beers:

 

What is the ground clearance going to be when it's on the ground?
Ron

 

About 6" The 69 has hotchkiss 2" drop installed

 

Looks great. :hurray:

No bone yard motor here.

Very informative thread John, I'll be following :thumbsup:

 

I would like to see you make a YouTube video of the rest of your work. Just a suggestion, looks like a wonderful project to be working on. I think it would be a blast to put an LS3 in my 67 RS convertible. I am looking forward to seeing your itemized parts & price list showing a first hand cost account.

 

Good idea. We'll do some video.

I'll have some time today probably to post a parts list.

The new EFI Fuel tank from Tanks Inc. was delivered Friday. You can do an inline pump but they are noisy and more prone to failures. Tank looks great and installs with the same tank straps.

I use the C5 Corvette Fuel filter/pressure regulator mounted close to the fuel tank. It returns fuel to the tank before it runs to the engine bay so the fuel does not get heated. Makes for a neat installation and only cost about $40.

 

I think this is fairly new http://www.holley.com/data/products/pictures/OilPanComparison_302-2.jpg

 

I think the Holley pan is the best. But it's not cheap.

 

Here are a couple pics of the Dynatech Header installed.

They fit very well and clear the steering box and a-arms easily. We will need to use either 45* angle or multi and plug wire boots on #5 and #7

Don't mind the old fuel line on the pass side. It's going Bye Bye.
