I run a solid, flat 246/260 @ 050 on 112 straight up with the sniper efi (dual quad) on a 030 over 360. The system allows for quite a bit of tuning flexibility, just need a laptop and time to watch YouTube videos on tuning it. Steep learning curve is all. Lots of good info on the sniper forums as well. Oh, and definitely run a locked out distributor and let the sniper control the timing. Last but not least, get a converter that’ll allow you to run the “gnarly” cam. Mine thumps hard idling at 1,000 and about 14.5 AFR.
One of the biggest things you’ll want to get comfortable with is the acceleration enrichment (AE) vs TPS rate of change so you don’t lean bog when hammering the the throttle. This was probably the slowest part of the system’s built in “learning”, so I helped it (after reading enough about it to help myself). Can’t speak to other systems out there. Good luck and have fun!
