What engine?
 
Can anyone run this serial number and tell me what this engine is? C600517. I just bought a sunsation rocket and the motor has the 420 air cleaner cap and the guy says its a 420. im thinking someone converted a 330 or 365 into a 420. I know the 420's came with cast aluminum valve covers and I beleive a weigand intake. This has an edelbrock high rise and taller edelbrock valve covers. I would just like to know what this motor started as so i know more about the internals. I'm hoping it was a Mag. Any help would be GREATLY appreciated!!!
