Finally after almost 7 years finally going to get this thing back on the street.

2011 LS3 bored and stroked to 417
4340 Liberty Crankshaft
4340 Eagle H Beam Rods
Mahle Pistons
BTR Stage 1 Cam
Ported the heads
Magnuson 2650 Supercharger with 103 MM Throttle body
120 lb Holley injectors
1 7/8 -> 3" Headers with Spintech mufflers
Holley Terminator X Max ECU
Wegner Drive Assembly (Yup I got the AC I mean at this point why not)
4L80E
Trick Chassis Differential 3.5 ratio with 35 spline Strange Axles
upgraded the brakes to C5 Corvette brakes
20x9 Wheels
Dakota Digital Dash

Figured might as well replace the brake master cylinder, brake booster, and heater core and dropping the fuel tank to replace and put 2 WAHL fuel pumps in new tank.

Still need to freshen up the paint and will have the seats redone as they have 30+ years of wear. New Window motors, trunk motor, and will need a new radio and keyless entry.

Just kidding. Sweet build specs. Let’s see some pics of the car it’s going into.

Yeah good point. And the Mustang for sure is not getting that engine.... just the exhaust

I figured I have waited a long time to build a hot rod and figured might as well do it right.... YOLO

I am worried that the stock hood is not going to work... I am wanting to keep it as stock-looking as possible.... you know for those Dodge Demons

Very cool build. How much boost are you planning on running? And is that cam the blower cam version or the regular BRT V2 stage 1? You are going to make a ton of power for sure, but I am not sure if you'll hit 1000.

15 psi @ 6000 rpm

For the cam this is the exact one I am using https://briantooleyracing.com/btr-pd...-camshaft.html
Until we get it on the dyno and get exact numbers but we expect it to be close to 1000 HP if not 1000 HP.

E85 mostly but putting 2 fuel tables in the Holley Terminator for 93 octane if I for some reason have no other option.
