i have a 622ci..big chief pontiac 14 degree heads...i run on gas a pair of 1200 dominaters....this motor was dynoed and made it max hp at 34 degrees..i have the dyno sheets in hand...1186hp at 7600..it also made 950 ft lbs of TQ..
Hope this helps...if you want to pm me a fax number i can send over the dyno sheets if you feel this will help you finger what your motor will make at what rpm etc......
just for the record..i tinkered around with the idea or placing this motor on alcohol and i was advised by several well known engine builders that this motor would make more hp on gas..i run c-16 vp fuel.
i do know that majority of the injected systems run on alcohol.
i woulsd still think your timing would be closed to where mine is ..if anything with the alochol you may get away taking 1 or 2 degree's out of it..
IF I WERE YOU...i would start out at 31/32 and go from there..this way you cannot go wrong..i would not think it woulf like no more than 34 or 35 tops..i get this idea from my 622ci.
Good luck
Brian
