Thread: 460 street machine

Tweet

Assuming you are building a naturally aspirated engine, 700HP would be quite a radical 460 in a street-driven application, unpleasant to drive in stop & go traffic, very obnoxious to the motorists around you (and eventually to yourself), etc.

Have you ever had a 700HP V8 engine and are you sure this is what you want for the street? And for your "first performance build?" If this is definitely what you want to do, then be prepared to spend some big money and also do more maintenance than what would typically be required of a street vehicle, especially in the area of valve train maintenance.

I would absolutely vote for a big stroker in this case, because the power can be made at lower rpms, and also there will be a much wider overall usable power range with the big engine. (Conversely, the little 700 HP 460 would be piss-wound all day long.) How you get to your desired HP range may be handled a variety of ways, depending on stroker kit size, heads used, etc. I would lean toward 4.3 stroke minimum, and possibly aluminum heads (would make acheiving the HP goal easier), etc.

I already know what I would do in this case, but don't know enough about your needs in such a build. What will this engine be going into? Must it run on pump gas? Aluminum heads or max ported factory iron heads? Perhaps most importantly, what is the cap spending limit on this engine?
