LS Rotating Assembly - Callies Compstar 8-cwt Crank & Rods, Manley 4.030 Flat Tops
This rotating assembly features a fully counterweight Callies Compstar crank with either a stock 3.625 inch stroke or 4.000 inch stroke with matching Compstar H-beam rods. The Manley Platinum Series, flat-top pistons with 4.030 inch bore are ideal for naturally aspirated applications. For an additional charge, this set can be computer balanced on our Fentech balancer to +/- 1 gram. The stock stroke and 30-over pistons yield a displacement of 370 cubic inches. The 4.000 inch crank brings displacement up to 408 cubic inches. The rods in this combination are Callies Compstar H-beams with stock length and journal sizes of 6.125 and 2.100 inches respectively. The Callies, forged, 8 counter-weighted crank is a very large step up. The additional counterweights reduce harmonic vibration and increase the stiffness of the crank by about 25%. It's increased stiffness and reduced harmonics minimize flexing thereby protecting the block, bearings and rods from excessive wear and fatigue. Get
