Modern Custom Built LS Engine with a Classic Look!

This sexy, modern custom-built LS engine is designed is going into a very cool build, a family-owned 66 two-door Chevelle that’s been in our customer’s family since it was new!

This Mamo Motorsports-built block features a 4.070” bore and 3.900” stroke that delivers 406 cid!

It’s a great combination of modern tech that looks period correct. The block features a 4.070” bore and 3.900” stroke that delivers 406 cid. It is outfitted with a user-friendly Hyd Roller Cam, and we chose the single-plane intake for a proper look, then finished it with the sweet Chevrolet-engraved valve covers from Holley that tuck away the ignition coils.

The single-plane intake on this Mamo Motorsports-built 406 cid LS delivers a proper, classic look for the 1966 2-door Chevelle it is going to power.

It runs 11.5:1 CR on pump gas an should make around 675 HP on the engine dyno! Hope to get some dyno numbers on it in the future that we can share with you in the future.
