hi trying to decide on a foundation for the build in my 95 delsol... can't decide on either a d15 y8 mini me, d16z6 block y8 head, or a d16z6 block y8 head w/ d17 stroker... i know the d15 has the best rod stroke ratio of the bunch but does the added displacement of the others more than make up for this advantage that the d15 has? plan to stay n/a if at possible...not planning on building a drag car or anything just want something with more balls than the d15 in my delsol right now...thanks for any advice/ thoughts u may have
