That makes it easier, it's 2.6 to 2.8 grams per CC of 2618 alum.
The 434" is ready to drop in, i was just waiting for the end of the season. I've got to make some changes in my motor mounts and front plate due to the 2" to 2 1/8 step headers, in fact i have to cut the stock motor mounts off the chassis to clear the headers. They are Lemons and i don't want to beat up a $1400.00 set of headers.
