Hey everyone. REally enjoying the site and I'm stoked to be starting an efi conversion on a chevy engine. I'm looking at either a built 350 or 383.

I've read some articles saying "the 7747 isn't good". I've also read "its hard to tune".

Here's some questions.

Can the 7747 run a more powerful engine than it was originally designed to run?
Can I run a built up 350 with up to 400 hp?

Are there any books on tuning that the members here would recommend?
the forums are tough to learn.

Do guys just download tuner cats or tuner pro and get the gear from moates and dive in?
i want the swap to be successful... Thanks for reading.

Jason
