go with a front mount I/C for a little bit more money you can't beat the performance gains over a stock location i/c
i have had the following i/c on my car
stock
stock modified ( dutt necked)
V4R dequik stock location i/c
RJC mega cooler FMIC
the stock location dequik worked great compared to the stockers but when compared to the RJC there is no comparison. i no longer have a interheater and the stock location resides where the hot-air is even with the crank fan and all the scoops and stuff.
If you are looking for a stock location IC, I *think* it was one of the Florida guys (Roy Garcia?) that went 9's with a PTE stock location. Ask 86Brick, I'm sure he'll know who I'm thinking of.
