looks like things are moving forward
, I found a reputable private seller on ebay with a short block that was willing to respond to me with some much needed info! FINALLY, what a rare breed of a seller in this day and age!
So he has two 350 short blocks, one that will give me .030 quench, and another that will give me .040 quench, and bored .040 over. The .030 quench block will give me 10.56:1 compression, and the .040 quench block will give me 10.3:1 compression.
When I get the short block, ill be sure to inspect and double check his work.
Even though ill have better quench, with aluminum heads and 91 octane, would 10.56:1 compression still be too much? It comes with a cam, but I might use my own since it has 288 advertised duration, which apparently could help with lowering the dynamic compression.
I was reading in other places, and apparently with aluminum heads, anything below 11:1 should be ok, anyone have experience in this?
