760hp 450-cube 1976 Holden HJ GTS

Laki Tsutsulis bought his HJ GTS as a rolling shell for a project car

“I BOUGHT my HJ as a rolling shell back in 2005 as my first project, with the intention of just tidying up the paint and building a 355 stroker for it.

CK Racing Developments provided the chassis connectors and the removable chrome-moly rollcage. It’s currently running 15x10 Weld AlumaStar double beadlock rims on the back, and 15x3.5s on the front.

Holden HJ GTS engine bayI decided the little 355 stroker just wasn’t cutting it anymore, and went looking for a tough street/strip engine. We ended up building a 450ci tall-deck Dart small-block with Racer Pro 13-degree alloy heads, high-rise manifold and a Dominator 1150cfm Bob Book carby. Big thanks to Dino Cecere, who fine-tuned it to get it pumping out 760hp.

Thanks to my mate Sotiri for always helping me out with the car; I couldn’t have done it without him.”
