Ordered the GM crate engine from JEGS, should be delivered to the shop on Friday. Also ordered a set of long-tube headers (with new O2 sensor bungs welded in) while I was at it, will have a local muffler shop install a new mandrel-bent system from the collectors back, probably a true 3".
I'm debating on doing away with the catalytic converters, and having BlackBear do a tune deleting them. Any idea on how it will affect performance, with just the new engine and the headers? I'm guessing about 20HP added with the headers, so I'd be at 275 before the tune. Calling BlackBear later today to see what expectations I should have...
Any other recommendations on bolt-on power mods that won't lower my mileage for reasonable coin?
