holds back the 250 from reving freely & smoother is the stock damper
Do the 194/230 use the same dampers as the 250?
I believe the stock 194 damper is a single groove.
Not too sure about the 230's,but I think depends on what year the 230 is for t to be single or dual??? Anyone care to chime in?
The problem w/the SBC dampers, is ,they require relocation of your water pump pulley,alternator,power steering brackets.
Or @ the very least you could run a SBC 6.750" damper @ have the "V" grooves machined into it. That would be fine for a daily driver.
What type of pistons did you install in your rebuild?
Dished w/a big chamfer on the top sides of the pistons?
Or dished & the rest is a flat top?
26 degrees of total timing is a bit low by about 8 - 10 degrees.
As far as drilling the crank for damper retaining,if you have room for a drill,you can drill it on the car. They are not hard to drill.
Stock fuel pump should be OK,but I think for an upgrade you ca use a 292 pump,they sometimes have a 3/8ths outlet instead of 5/16ths? But ask here from the BB for a more definate answer.
