All, am in the process of finally putting together my 451 stroker motor for my 64 Sport Fury. I am using using a set of Keith Black 280 stoker pistons withe the quench pad milled to fit my heads (ported 462's) with Total Seal gap less 2nd rings. My problem lies with the oil ring groove on the pistons, they come with a supprt rail (.030" thick) to cover the wrist pin bore gap. With this support rail it is impossible to install the oil ring (upper/lower rail plus expander) due to lack of clearance. KB tech says run with out the support, while Total Seal tech recommends not doing that ad getting the oil ring groove milled/widened the required .030". This is my first stroker and thought I would throw this out to the group. Opinions? Comments? Thanks in advance Nico Over Va.
