im puggting together my stock shortblock with TFS stage 1 cam and gt 40 p heads... i was wondering what would be a good rocker to go with for this ecombo for the money? also specs on this cam are .499-.510... what would 1.7s bring this up to??? thanks!
0.31875*1.7=.541875 lift. This is over the supposed threshold of .544" of lift before contact. You need to clay that motor with 1.7's to make sure they will clear.
Unless the P's are ported for additional airflow at higher lift you may not benefit much from the additional lift you get from 1.7's vs. 1.6's with that cam.
