re home porting.
I dont discourage anyone from trying anything,,,,Ive done it myself. My only point is or question:How do you know how much in the way of improvement you gain by home porting?
I start with a 150 HP engine,add better intake carb,cam,headers=now I have 250HP
the home ported pos heads add how many more HP?lets say another 30,now round that up to 50 with a super tune.I now have a solid 300 HP engine(unvarified)
this equals good experience,because,,,,next time I will start with a 300 HP engine and apply my past experience.
when you start to make bigger power IE more than 1 HP/cube then parts will need more attention to detail.The more HP you make,the more it costs per HP.This is where the phrase "no replacement for displacement" comes from.We all have to work within a certain budget and these discussions need to be geared towards that part of the engine build.
With me I zero balance all engines as to me,the smooth running,especially at higher RPM and the added life make that process essential to me
maybe with you,a hydraulic cam,though giving up power is worth it for the nasty idle and not having to make adjustments
