What is the difference between a 429 cobra jet and a 429 thunder jet. Internally, HP ratings, which is a better buy. Is there any way to tell the difference just by looking at them from the outside.

Yes and thats about all I know about them. masterbeavis 10-19-2005, 06:39 PM the thunderjet is the same motor as any C8-DOVE headed motor. 365 Brake HP on 110 octane gas. (for the 460) | |
