TQ questions

I would use the 9811s. It is calibrated for a 318. It should work the best with your combination. It has ported vacuum port for the distributor. Plug everything but PCV, vent tube, and distributor. I tend to use the KISS principle, so I would not use the 9265s there is too much complication there. The 9080s does not have ported vacuum and is calibrated for a big block.
