Which throttle body are you going to use? Holley has an 1000 cfm throttle body that is plug and play with their main harness but if you want more CFM than that then you can look at Wilson or AccuFab. You just have to be careful to compare the specs since the Holley throttle body has the TPS, IAC and MAT functions all built in. Sometimes the MAT isn't included so then you need to drill and tap the intake for the MAT sensor. Rich can help you get the correct throttle body.

If you have a 1000+ cfm throttle body and a Wilson ported Victor intake then I think your engine will pick up power over the six pack, especially on the top end. You might lose some torque down low but you should pick up power on top. Not sure if you'll notice the difference or not on the street but you would see it on the dyno.

They dual sync does make the install easy. If you haven't ordered all the parts yet then shoot me a PM. I have a set of smart coils and some wiring harnesses that I could make you a deal on.
