Supercharged 403ci '64 Bonneville build
 

Hi guys,

I originally built the 389 in my car up to a 400 with a mild combo, then upgraded that with Edelbrock heads and EFI, then chose a different direction as Pontiac parts are too hard to source down here in Australia. I wanted something I could drive long distances, which would make great power and still be easily serviced.

It wound up with an iron 6L LQ4 block, Texas Speed 403ci stroker kit, their LS3 CNC-ported heads, custom cam, Johnson short-travel tie-bar lifters, custom-length Manton pushrods, CHE trunion upgrade in LS3 rockers, PAC valve springs, a Moroso sump, all Gen4 sensors and wiring loom, Haltech Nexus R5 ECU/VCU, Harrop 2650 intercooled supercharger, Raceworks 1500cc injectors and Turbosmart fuel pressure regulator.

I figured it might be interesting to see a "junkyard LS" build that isn't quite Sloppy Mechanics-spec :D

Way cool! Nice work
ETA: Great videography as well.

Very cool nice car.

I applaud you for going with a tried and true MODERN solution to keeping these OLD cars moving.

Seems to work fine - has good pedal feel and never has an issue pulling up.

Curious what you did for an exhaust setup to get it to fit? Did you use headers or manifolds?
