CBM NA 490 RHS TALL DECK
Introducing the new CBM Naturally Aspirated 490ci RHS Tall Deck racing engine, this build will be going in a 4400 class
Ultra4 car. We started out the build with an
RHS LS block with a
4.165 bore and a 4.5 stroke. After balancing our rotating assembly which consists of a set of custom
JE pistons, a set of
Callies Ultra connecting rods, and a
Callies billet crankshaft we moved forward with the installation using
ARP fasteners through out. In the camshaft department a CBM/
Comp Cams custom grind solid roller was used, with our compression ratio @13.7:1 we now have a solid foundation for this tall deck beast.
Check out part two of this featured build in the up coming 2020 July issue.
