You're not going to make 300whp efficiently on a stock D-head...for one ask Derka on here, for 2 my buddy built his single cam and was LUCKY he made 300whp. My stock boosted b20 would have walked a stock boosted single cam...and by the way I spend $400 on my b20 swap food for thought if your going to try and compare prices.
