The 170 had a shorter stroke than the 225, but the same head and valves. Low end torque was less, but ultimate power was the same. In addition, with the lower block height it was a sturdier engine, and with the shorter stroke could rev higher with less chance of an rpm failure.
No wounder my 170/ want's to keep pulling after 5.200 :glasses7:
But I was thinking and have seen it said here that a 225/ will give me a good gain in HP being more C.I. / displacement.
My 170/ is a none oil burner and no blow by, a perfect running engine :glasses7:
But I do have a new head Frank built (66aCUDA) took 40 thousants off for me and a bit larger valves, I told him I did not want heavier springs for my aplactions.
My 170/ just has 67.000 mile on it, so you think I should stay 170/ revving engine over the 225 longer stroke and more displacement :glasses7:
So, the crank
is a different throw
ops: it's shorter, so I guess the rod length and all in all the same rods that a 225/ has compared to the 170/6.
:-k so all I will be getting is more low end torque :-k
3.23 gears 2.700 lb car standard shift :-k:-k
I will need a early 225/6 so I can keep useing my trans (pilet hole mach) :-k
But I quess the machine shop can drill that out for me if I go 225/ I quess ?
But they do make 225/6 headers, no 170/ headers out there being made..
Decisions Decisions Decisions !! If my boat comes in Victoria will be gone getting some new metal and skin on and I was looking at building a short block to keep me busy...
