Made it back to the dyno today. Original numbers with Xhead 302hp,323tq as delivered from BDR. This had 10-11 air fuel ratio. After only the head swap to AFR185's and no tune, numbers increased to 383hp, 375tq. The air fuel ration leaned out to the 11-12 range. After making about 10 pulls, and playing with timing and jets, I am at 415hp, 415tq.
One thing we did notice, is that my fuel pump is getting near its limits. It has a Carter Electric pump with a gold top. I have tried to find information on it but have not found it anywhere to see what its capacity is.
