RoB's Ton of Boost Build.... Day 1

Foose04 · 08-01-2012, 08:00 PM

It's here, the chevy's next "little" mota. Goal? Ton of boost and keep it together. I've gone pretty far on the stock stuff, really excited to see where I can go on a forged setup.

Looking to be a little different then most LS builds. Won't be the standard 370/408 iron block and 90+mm. It will be a small cube build. I want to keep the walls thick and the weight down. I plan to use some thick deck heads and let the boost make up for displacement. The way I always have.

The block is a L33 5.3/327 Aluminum block. Looking to get a light bore and clean up to get me started. Need some recommendations on a good local machine shop. Next will be ordering a forged rotating assembly and picking out the crank stroke.

The build won't happen over night, i'm currently in no rush as long as the 4.8L can hold on the rest of this year. I'd like to have it ready to fire off first of next year though.

Thanks guys, I'll keep this thread updated along the way.

Very nice, looking forward to seeing what you do with it!

schardbody · 08-01-2012, 08:56 PM

what made you decide on the aluminum block? i couldnt imagine it will handle the load you are putting on the iron block now.

DolSVT00 · 08-01-2012, 08:59 PM

Nice Rob!

Simmons does all my machine work, their about the best around with mod motors. Not sure how the do on the GM stuff, but I'll tell you this, if you rush them you may have bad luck. if you let them just do it, ive never personally had a prob.

Yea but they certainly don't reuse the stock sleeves lol.

1998ta__1991rs · 08-01-2012, 09:22 PM

dons is the only local place i would trust.

Foose04 · 08-01-2012, 09:27 PM

The sleeve have enough meat on them to be bored to 3.905 and still handle a power adder. I'm just looking to clean them up to 3.80 or so. Thats one reason I went 5.3 instead of ls1 was for the sleeve thickness.

slowgreen99 · 08-01-2012, 09:28 PM

id say S&R for machine work, and good luck on the build Rob! I can only imagine what its gonna do now lol.

id hope everyone knows my background on "the 2" places lol

ShawnBoyMoody · 08-01-2012, 10:25 PM

Lol he might not! Careful lol.

Foose04 · 08-01-2012, 10:32 PM

Is that the place who "Race Balanced" a set of pistons for you?

And it would be nice if a couple people could agree on one known Ls shop. Lol

i'm certainly not questioning Rob, just curious. i cant see how an aluminum block could withstand the same or more power as an iron block, but i'm not daily driving a 600+whp 4.8 either, he is, so its obvious to me he is no dummy! i'm basically asking if he knows a secret...

Honeycutt on a serious note rob

No secrets, just personal research from the net to a couple LS engine build books. Examples from 8xxHP and over 1000TQ on a stock aluminum l33 setup to forged ls1's making over 1000HP, usually with the walls being the weak spot, not the block.

I've also read and been told the 5.3 was the strongest stock LS aluminum block. The have the most meat in the sleeves and I think paired with the right heads it should be one hell of a boost engine.

It's a different way of going about it, but I really like the 80+ pounds removed from between the front tires and taking a different path.

Only one way to find out.

Info on the bores from "Motorbooks/Workshop, GM LS-Series Engines"

Thanks for the info Brandon, ill check into those guys.
