555 CI Big Block Chevrolet

Being installed into a street driven 1970 Chevelle. This Big Block has a Callies rotating assembly, JE pistons, Brodix BB2x heads, and a hydraulic cam. We ended up with 675 HP and 700 TQ which should equal Big Fun!


Before the 340 there was the 273. These were available in Darts, Chargers, and Barracudas as well as other models. This one came to the shop for a stock rebuild. Most came with a two barrel carburetor but this one has a four barrel manifold. We swapped the Carter AFB 480 for a Edelbrock 600.
