"Ok here is the best bet to fit under the stock hood, no guarantee's but it may work as you can tell in this pic. You WILL have to run a box upper intake which will kill your torque down low, however it MAY fit."
This will not work with the stock hood.I have the Downs upper and gt40 lower, and I have a cowl hood and it still rubs at the back closest to the windshield. As soon as i get my heads finished and get it all back together i will try to post some pic's.

. The other consideration for me personally is if I can get a 408W to run well and still squeak through emissions (have to pass an actual sniff test here in Orygun). That may force the issue, a turbo should be easy to get through the sniff test.
