Hey guys, so now I'm in the meat and potatoes of this build and so far its going nicely.

I purchased a bone stock lowered 07 silverado regular cab with under 55k miles and immediately sold the motor and trans. It had a p1 that was not on it yet when purchased but I sold that and upgrade to D1.

Purchased a low mileage bone stock LS3 and had it built to a 418 stroker. Just got motor back from the shop and everything else is here or on the way.

Here is a list of what I have purchased so far.

Motor:
LS3 418 Stroker
LSA heads
Holley Sniper sheetmetal intake
NW 102mm tb
Tooley Cam
headers sw exhaust

Fuel: e85
ID 1300
dual Aeromotive 340 pumps

FI:
D1 procharger
HOB 8 rib bracket system

Trans/driveline:
Jakes Performance 4l80e level 3 with trans cooler
Jakes Performance triple disc billet converter 3600 stall
PST 4" driveshaft
detroit locker
4.56 gears


no idea what power as long as it's more than 700 whp.. D1 because of its street manners and it's boost through the rpm range. This is a difficult step for me not to go f1..lol

 

And here I was excited to boost my 4.8 lol. I cant wait to see how this goes!! Sounds like its going to be fun. Oh wait your going with a supercharger, it still won't be any match for my turbo 4.8

 

It's a lot of engine for that blower... it will be a power house, but you may struggle to make 12PSI believe it or not.

 

Lol you can spin that 4.8 pretty damn hard and turbo should be nice! I've always been a whipple guy and had a 2.9 then a 4.0L whipple on my gt500. After the oil pump shattered, pulled motor and rebuilt entire motor again. This time I went with a single precision x275 promod 88.

 

Tell me more about this. I wanted to stay with a d1 for better street manners but why would you think it will be hard to get that boost? I'm just looking to get north of 700+ whp so what would you suggest I pulley it at to achieve this?

 

What pumps are those? AEM makes a 340ish pump, but I like the walbro 400 and 450 pumps a lot better. If you want E85 I would highly recommend dual walbro 450s.

 

Hey Mobbn,

Friend of Thyssen Rob. Building the 07 Silverado with the 5.3. Can text me @772201172.

 

Yes I'm wrong, they are dual Aeromotive 340 pumps. I have two walbro 465's at my house from my gt500 that were only used under a 1000 miles. Doing larger fuel setup in that car now so I was thinking of using those but my buddy is going to use them in his 5.0 nitrous build.

 

Hey, number is not complete missing a digit
