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.
302 heads
lelo, that was my next question, if i port the heads i have based on the head porting sticky on here and have them milled slightly that should be a big help theyre supposed to be 60-62 cc's am i correct in this thinking. and does anyone other than kb make a higher compression piston for the 318?www.forabodiesonly.com
and one just on the current build
I've seen A LOT of posts about making HP with a 318-So why is it so ???
There is a stock 318 long block low cr build that made 282hp @ 5000 rpm with 4bbl and headers and a xe262 cam, add some cr and bigger cam can't see why you can't get 300 hp out of stock heads, but if your buying pistons for cr might as well go to with better heads. Doesn’t that defeat the “Cheap...www.forabodiesonly.com
Thanks, great write ups there by CPDave. Good detail of components and results on each engine combo tested.
He put a lot of effort into gathering that information.
Thanks
