That is a lot of years in development!
Wish Ford had kept up work on the Boss 429 engine for a few years.
Now,Jon Kasse has taken up the task and is building new Boss 429 heads that will work on any 385 series block.
Dyno runs with stock 429 cu in,and a single carb(no blower) have shown to be an impressive 778 HP at around 6200 rpm.
1.81 HP per cu in
His 521 incher made over 900,both were on pump gas at 10.5 to 1 comp
As we speak he is putting together an 08 Mustang with his new engine , goal is 1000 streetable HP on pump gas.1.92 HP per in with a 521.
Still no substitute for cubic inches. |
