Cam is 230/236 113 and I’m on stock heads.
ive actually got everything together to pull the heads, coz at 135k I want to renew the lifters.
Im thinking a lot more compression and a little porting , and I just picked up a 218/228 118 .6lift cam. It’s a bit Stinky with the cam it has now, so porting/compression to keep the top end, and a smaller cam to keep the low.
thats the plan anyway.

ITB explained

ITB’s are great but variable length intake plumbing is where it’s at :p
The Mazda 787b race car was one example. F1 also uses such but there are other examples.
The following (annoying) video explains some aspects and shows a pic of the 787 4 rotor engine.

Road cars tend to use dual length runners with a valve selecting the length at a given RPM.
The following video may explain that

Sounds good. Good luck with the changes, sounds like it should be a great street car.
