New G3 Hemi Block...

That’s all of 750 HP and then some. How long has he been beating on it?
Over a year now. He had a 5.7 stoked to a 6.4 with 13.5.1 compression. Dont remember the size of the cam it had in it. But with the same intake,carb headers and maybe the heads. His 71 Duster ran right at 10 flat in the 1/4. Ran a few 9.98 I think.
