Who to go for SOHC Head Porting ??

[chunkhead]

300Bhp is easily acheivable with the SOHC as is a heap more power! 500 would really be straining it, but no reason why it shouldn't for a dedicated drag car! I'm aiming at about 300bhp atw for a street car and i will NOT be going to the DOHC! Waste of time and my money, not cheap...! I still have to work out how to keep 300 on the ground!
