Opinions, lots of opinions.
I do like to build ZVH engines, my opinion is the oil system and the block on the Zetec blacktop is considerably better than the CVH and silvertop. The CVH head once you modify the rocker stud holes is totally reliable at 7500rpm, it also is mechanically strong internally. My findings are just the same as Karls and agree with pretty much everything he says (never met him or even spoke to him
.
Scotts engine is my old engine just freshened up and put on new management, my old box also. Its on standard valves and springs with solid Newman follower and a big cam to suite the GT30/82 turbo.
If Scott was to take the final drive from a Mini Copper S (same box) that would give him a higher top speed as it revs out at 155mph currently.
Also been thinking about Scotts build this winter and would like to take a bit further.
It was running 28psi and that was the traction limit on my old dyno with 4 people on the bonnet and ratchet stapped to the ground (205 40 17). My new single roller Dynojet should not have any issue in getting it wound up more. (fingers crossed)
