Atk lq4 hp93
How about this engine from ATK? It's the LQ4 HP93. Has anyone put that in a 99 nbs? Summit Racing thought I might need an intake from an 01 or newer and possibly modify the wiring harness.

Nice. Yeah, I was going to call Thompson. The power ratings are right where I wanted to be with this one though. what are you making with yours?

I understand not everyone wants a max effort engine. And no doubt that engine would run well and be fun to drive. But they could've at least used arp hardware and 243s for the price.
My engine's numbers were disappointing. It was pulling vacuum on the intake after the heads went on. Only dyno'd 404/408. It still runs good. Kind of at a crossroads on what to do next with it though.
