Default wish i could help

we have only been building these for 16 months so it would be hard to find one S/H, you say the one on the dyno sheet has ported heads, it is a 6.0 litre with no head work but rolla rockers and crow cam, i will send all the details to your PM so you can go over them, o and have a look at the new car for this week

I even have been trying to join a board in aussie land but the email to activate my account wont come though. Dont tell me I havent tried fucko.
Email me via ken@harrop.com.au and I will send you some comparative dyno sheets (independantly done by a well-respected Aussie race engine builder).

I caught this thread a little late. Your manifold looks great! I have always thought an 8 throttle body would beat a single throttle manifold. However, I have a question. I remember in the 90's that the turbo Buick was one of the more powerful engines at Indy. I remember one year that they came out with a mono-valve manifold that made more power than the 6 valve manifold. They said the only downside was it was very peaky. Do you remember this manifold and why it made more power than the multi valve units?

Thanks,
Glenn
