There are heaps of 308s out there running at +0.060 but they do seem to get hot - might just be a co-incidence. If you are going to the expense of a stroker I wouldnt use a block already at 40 thou. Id go looking for a standard bore block and build it at |

Stroking to 350, not 355. 355 is boring AND stroking.

Just to expand, from memory they were Repco? designed/modified F5000 blocks and used by Holden for the L34. An NZ prefix is also a good one to have.

sounds good, just need to know engine letters and first 3 numbers. because it could be a vk black block. going off the date castings doesnt tell you which decade. eg 74 or 84 .regardless they are good blocks
