sounds fine Bruce and must be a little beast in mid range torque-wise...
I guess you also used the 300 rods to keep the same engine height...
however a couple of things still make me wonder... stock head has tiny intake ports and valves for oem displacement...if still stock there, with the extra cc doesn't it "choke" on the high end ?? unless you mean 300 stock... did you need to evaluate anything concerning mean piston velocity or is it safe (250 18,23m/sec 300 cranking on 250 electrics 21,64m/sec for the piston at 13250rpm...)wiseco piton lighter than stock (stock is 124grams, 130 with rings plus 36 with oem pin)??
I bet you still have some upgrades to go...well done !!
can't wait for those figures from the dyno...
