Help Needed - Budget 318 Sprint Car Build

Well I will tell you this, I am a die hard Mopar guy through and through and have been involved in alcohol winged ashpalt sprint cars and Mopar engines were just to cost prohibitive to run. We have like almost every one else run the small block Chev, our 650HP cast iron dry sump engines complete with injection and mag ready to run were about $35,000 Canadian and you need two to keep them fresh. Up here in Canada the Mopar would run at least 30% more to build maybe more. We now run a non wing Beast chassis car on gas with a 2 barrel carb and wet sump, makes a bit less than 400 HP but its still fun but a fraction of the cost of the alcohol engines. We have considered building a small block Mopar for this class and so have a couple of other teams as in this configuration the cost would be closer to that of the Chev, we would use the 358 combo.
