IF you're on a facebook there a few good sniper pages too. Don't be scared when you see "everyone" has questions and concerns or issues. They are tech and help pages, so that's the type of questions that get asked. Good info on tuning, set up, etc, Holley is an active member of at least of them too. EFI systems pro site has some good write ups as well.

You will also most likely need a throttle cable bracket, either lokar or FAST both make one that fits well.

Will the EFI unit bolt onto a spreadbore intake without an adapter? Holley recommends a sealing plate.

The Snipers are dual pattern, so it will go on without an adapter/spacer, though you should make sure the blades aren't hitting your intake, which would then need a spacer for sure.

The sealing plate recommendation comes after some complained of a whistling sound. Some like the whisle. Some have such loud beasts under the hood, they cannot hear the whistle.

This will do the trick and help keep heat away from that little computer in the TB. As I see it, keeping heat away from the computer can only be a good thing.
