Those interested in actual 318 testing and development should bookmark
@CPDave's posts.
When he bought the Dart from Josh, it had a Dick Ott built 318 with a 262 adv duration, 420/420 lift cam.
My experience was that it had a
very responsive throttle.
The reason for developing the 318 was that he (Dave) was able to get it into the SVRA rules. (Otherwise he'd have to use an engine under 305")
Anyway. here's the post that outlines the development.
