Re: bbc 494

It would run just as good as any other BBC build. It all depends on the quality of the build and how well the parts are matched. Based on the parts you have listed, probably in the mid to high 10's.

Sounds like you're building a race engine. So, why that choice of intake? A single plane (and I'd take an Edelbrock or Holley over Professional Products any day) would probably do you better.

Transmission?
Rear end?
Tires?

If all of those are "stock", I'd say 14's.

Got a 6-point in the plans?
