If the two-fours cost $225, I wonder what F.I. cost?

Cool car, don't see many factory dual 4bbl cars, but I guess that engine is long gone. Almost had a new engine every two years!?

Re: '57 Chevy LS3/4L60E, Thought Id share.
 

Traded years ago for a alcohol hilborn/enderle 301 set-up.
The engine count isnt to bad considering the hardcore 7000 to 8500 rpm drag racing in the last 55 years.

How many rearends?

Re: '57 Chevy LS3/4L60E, Thought Id share.
 

Not sure....I will have to ask him.
It's had the car 12 bolt for along time, It's blown up once since ive been taking care of it, But the case was unhurt.

That's way cool, not many raced cars look that nice, especially 55yo ones.. I would imagine with that much use it's had to have a rear or two.
