I have a brand new HSR 7540 base and plennum, but need a vortec base in order to fit the motor I am wanting to put it on. I'm looking to buy a vortec base or trade the base I have. I am replacing a superram with a SDPC vortec intake due to needing space (only 800 miles on it). I will trade my setup (superram and base) for your vortec HSR+$ on your end.
