Quote: You guys are talking about a 4.25" stroke. We couldn't put that much stroke in our Ford motor due to rod to cam clearance. Read that we don't have enough. We have to slightly grind the big end of the rods for 4.09 stroke.
Bob, on other forums I've commented (and questioned) the combination of this low rod to stroke ratio on this package in regard to ring seal and ultimately life span... Any comment on a 1.3 compression height and 1.5 R/S? My assertion is that it should be expected to live a shorter life than a 4" arm and that the gain in power for that little more stroke isnt worth the expense.
Dave,
We ask our motor to live 30-40 runs so longevity isn't in the equation. Since there are other aspects of the piston/rod/stroke that are much more critical to making power we don't even concern ourselves with that stuff. BAE doesn't either. They have a shelf piston that works for almost everything. Compression is controlled by rod length.
