um what exactly is a challenger class engine, i saw an add ina magazine and was just wondering. its a 350 .030 over. other parts im not sure of but whats the diff between a challenger and a reg 350?

 

... stock car engine. Depending on where it ran, the track rules dictate what parts, combination, cam, heads etc. that could be used in that division.

ok so from what you say i guess its not really a good streetable engine more for the track and stuff. or i guess what sort of components it has i guess

 

I guess it depends what you are looking for. Are you looking for a drop in motor or a project?
Your best bet is to inquire with the owner and determine what internal components are in the engine ie; you already said it is supposed to be a 350 + .030, but you will want to know what casting # on the heads, type of cam and specs, pistons, # of seasons of use, etc.etc.etc. Keep in mind stock cars are often required to run smogger heads, cast pistons, two barrels and limited cams. The engine spends its existence between 3500 and 6500 rpm, from full throttle acceleration to engine braking into the corners, pretty hard on cranks and thrust bearings! The cams are often either custom ground to maximize hp at a certain rpm band and/or degreed to move the power to a higher rpm.
