I'm building a new 350 Chevy Street Stock motor and am looking for input. In the end, I want an honest 425hp and I want to be able to turn 6500 rpm comfortably. I had my last motor built for me and was kinda unimpressed, so I'm tackling this one myself.
I've assembled street motors before, but all I know about this engine is that I want forged pistons. I have a '69 4-bolt block. What should I use for rods? Do I need a forged crankshaft or can I reuse the stock one? Dependabilty is of foremost importance.

Also, the heads will be cast iron Dart II's with a solid lifter cam. I will probably run out of money before I can port and polish the heads, so they'll be "as-cast". Any advice on a cam selection? The track is 1/4 mile, moderately banked. One set of turns is pretty tight, so I need a good amount of low end to get off those turns. The other set is pretty big (its the dirt Darlington of Illinois). The rmp range will probably be between 4000 and 6500. I know there's a ton of questions here, but I wanted to give all the info in one place. Thanks.

What are your track rules as far as motors go? can you deck the block, can the pistons stick out the hole, can you run after market rods, can you run any head/ with any work, and what are the intake rules......what about cam rules, and rocker ratio rules?
Those would be the questions I need answered before I feel anyone can give you a good honest opinion of what to build.
