A SuperCar stock cubes build would be the way to go with the parts you have. (if you don't stroke it) You will have plenty of competition in your E/T bracket. FYI, the current stock cube Hemi record is 12.61 @ 112MPH owned by Billy Atwood and his 1969 Hemi 4Spd. GTX. Billy's GTX is not a max effort. I am sure if you build a stock cube Hemi you can get it into the mid elevens without all that much cash.
Also, when and if you go Cam shopping, we have the best ever cam guru on the payroll. Let me know of you need his expertise.
We have been very focused on car count and series name recognition, we are very excited to say we have seen a significant increase in car count, web traffic, forum traffic and participation after every event. With all the success we are seeing in SuperCars, we plan on giving and adding recognition for stock cube builds on the web and in certification.
