The Holley systems are a bit more money but Holley offers after the sale support and replacement parts a LOT longer than Edelbrock. If you have one of the earlier Pro Flo systems, say from 5+ years ago, you can no longer get replacement/service parts.
S&J engines is local to me and I know 2 people that have purchased engines from them with excellent results. I would not hesitate to buy an engine from them.
If on a budget, I agree on keeping the stock intake since you can now purchase the EFI spiders with larger than stock. injectors
