Ls376/480

[rsk68]

What would you do to a new LS376/480 motor to increase the HP and torque a bit, maybe just a different cam and FAST intake? I have been looking at 418 strokers from some vendors but am a little short on cash! Would I need to upgrade rod bolts also?

Thanks for any info!

Hey Rick,

Have you seen this article? Its two years old but should give you some ideas on what a cam change can do for power in an LS3.

An LS3/480 already had a bigger cam than an LS3.. something like GM HotCam.

And that number is low.. on a engine dyno, with long tubes it's way over 500hp. You could go with an even bigger cam and maybe have the heads massaged.. but in that case just buy an LS3 since you're paying extra for the larger cam/springs.

I have one sitting in the shop waitin to go into a 71 Chevelle wagon..

We talked about the 418. Just do one of our LS3 / 540HP instead of the 418 Rick With forged pistons is only a few hundred more then the 376 / 480HP and with forged pistons you can force induction it later or spray it with NOS!

If your really considering LS3's, keep in mind that our motor already comes with a $425 road race pan to fit first gens and A Bodies, so the cost is technically the same as the 376 / 480.

Same engine I have Rick, though Iam still selling old parts,and need a 4L60E trans to finish and get the damn car running before the end of summer ( I hope) But don't worry, I went for a test drive in a buddy's car with the LS3 and all he did was add some headers and a full exhaust, all I can say is the power is scary in these engines and it pulls hard! I hope to find out for myself soon lol..Congrats on the new bullet!

Two long weeks Rick.

Rick got this one

She is on the way Rick, Ain't she purdy!

Frank...what serpentine kit is that? I like the way it looks.

[ProdigyCustoms]

That is our Wegner Drive

Here is another better view of the front drive

The belt wrap is the best in the industry with special attention to the PS which is a BIG issue with fat front tires.

Very nice Frank, thanks for everything!

Been making some progress on getting this into the car, today i modified the fuel rail to us a AN fitting, i didnt like the snap on OEM type.

[Samckitt]

How did you add the AN fitting to the fuel rail? I like it!

[rsk68]

I took a 3/8 pipe to 6an fitting, machined the pipe threads off and bored the hole to fit the rail then had it brazed on.

[The WidowMaker]

one of the mags just showed the fitting to go from push to an, but it doesnt eliminate the push part. i like what you did.

[vstol]

keep it going I plan on ordering one in Feb, just not sure if it will be the LS3/540hp or the 418 620 Carb

Where did you find the original part? I've been looking with no luck, did you use stainless? Want to make another one, what would you charge me?
