Trying to get a reasonable baseline of how much a naturally aspraited 13.1 540c.i single dominator motor; fully cnc'd 325 darts w/ matched sniper intake. will make. Cam is a flat tappet (for now....).valve lift is .720. [email protected] 50 is 284* on a 108 lobe ctr. I know a mechanical roller would be superior; Just a ski motor deal. If...... and i say possibly if this combination makes 1.5 h.p per c.i i will be pleased. Would'nt mind hearing some of your opinions.
