I'm putting my straight gas 351 XC on the dyno on Friday to sort out the gas mixture. How much or little hp do you think it will have. 351 2v open chamber stock heads. Impco 425 on standard manifold, cam hyd 194/201 @.050 .439/.464 lift 112 lobes. Std ignition, p/steer,A/C, fmx, 4 into 1's, dual 2inch exhaust. It's a very mild combo for heavy towing I rebuilt 9 years ago. 160-180 hp???
it was a Dynomax dyno, the result 115kw or 154hp. Pretty poor result for a 351 started out at 111kw, after leaning out the mixture a bit it went to the mind altering 115kw! Strange thing is it keeps up with a friends BA xr6 manual and pulls away from BA autos.
