Holbrook Racing Engines
in Livonia, MI built
her. Given the engines around their shop I felt a
little inadequate having them build a 349 for me. BTW
- ever wonder where Ford sends their crate motors for
warranty repair ??? The idea was to reuse everything we could from
my 306 but sadly more was replaced than kept.
The 306 block was too badly scored to to be machined soooo....
we started with a new "old" block (1970 302) which is
significantly more robust than the later generation blocks
and weighs around 50 lbs heavier. Since
these blocks did not use roller valve trains in their day,
we had to pay attention to the valve train:
1. had to drill and tap holes to hold the lifter spider...
2. had to go with a new "small base circle" Comp cam along
with new push rods and special Comp Cams "retro" lifters.
Check out he video section.. and turn up your speaker "bass"
to hear her run.
Even though a 427 big block would be nice for bragging rights (and torque), the lower mass of the small block will balance the car perfectly.
A few more changes and we're up to 440 HP / 445 ft-lbs ....it should really move this 2200lb Cobra..... all I have to do is find traction. While
this engine will deliver more HP and torque with a single
plane intake and bigger Carb (670 Holley), I'll stick with
what I have for now - it is certainly no slouch.
