Component machining, block clearancing, balancing rotating assembly.

We go through the process of clearance grinding Holden V8 cylinder blocks to fit a 383 Premium Stroker kit. Keep in mind this video was made prior to our development of our more compact Stroker design billet 4340 steel H beam rods now supplied in all our Stroker kits. These rods used in the Holden V8 reduce the clearance grinding requirements significantly. Hitting the water jackets has been made a thing of the past due to these wonderful con rods.
The only possible reason for breaking into the water jackets is EXCESSIVE clearancing (you need only .040" to .050" clearance). The only other reason would be a block that has very severe core shift. This is actually very rare in Holden V8 blocks from the HJ (1974) model years when Holden began using patterns made in house at GMH at Fishermans Bend in Melbourne. The original patterns were made in the U.S GM factories and frankly left a great deal to be desired. This was the reason for inconsistencies in blocks made from 1969 to 1973, the HT-HG and HQ model years which all had the Chev Small Block type rear main oil seal. It's a better idea to use the later blocks made from patterns built locally.

We look at the minimal clearancing required for the LS Chev blocks to accept our 383, 408 and other stroker kits.

We do a detailed look at component balancing for the rotating bottom end assembly.
