Apperently this motor is rebuilt with a performer intake, 600cfm edelbrock performer carb and it had hooker headers on it. The owner thinks its a 390 and it's in a 68 pickup. He bought it this way.
I have seen alot of stuff on the internet that say this could be a 390 or a 428 or a "330"????, or a 428PI(police interceptor)
Does any of this info help with what motor it probably is?
Thanks
