And he did it with stock 273 heads (ported, I know...). Impressive! I would think the bigger bore of the 318 and better heads may get the 42 more hp needed for 500 hp @ 6500 rpms..... Just food for thought
More piston speed, say 7400 or so.
The example giving has fudged numbers, it was more like 7400 .
and I question the ported 273 head
There is a 273 dyno sheet in the 8000K thread. lol
