Big Inch Smallblock

I hadn't either until today. Brett Miller has been working on some preliminary W5 work with intentions of having a new casting done. Last week he was looking for Virgin W5 head castings. By Wednesday already had some and 2 day's later had a finished port going [email protected] which is already more than I've seen and better than Indy CNC -1/-2. I'm sure with a better casting without the deep spring pockets plus other fixed areas this will be a wicked head to make some steam. Hope it works out.

I’m sure you read the Facebook post and were I asked him if it stalled or backed up at .600. He said the head was done and he was questioning going with that big of valve. Look at the .300-.400 lift numbers and check out how bad the valve angle he used hurt the low numbers.
