Cast iron: 3919840
Aluminum: 3919842

Of course, the numbers I posted above and here, are for the high horsepower cars. Yenko also sold lower horsepower cars and bone stock configurations as well. Just because it has "Yenko" on it, doesn't necessarily mean it's a Yenko high horsepower car! He offered 427 conversions in different horsepower ratings, depending on what the customer wanted and what he/she was willing to pay!
