11 second street car?

Shipping is cheap...

There are good builders in every corner of the country. Find the one you are comfortable with, know your goals and go with it.

It doesn't really take a bunch of engine to run high 11's. Building a 360 would be the easiest or a HUGE shot of juice on that 318. :)

Don't know a budget. A stroker would be cake to get there and would run in the 6K+ range is my guess. Here's something that would get you there and likely a little less $ than a stroker.
360
kb107's 9.5:1 ish
RHS 2.02 heads
Comp XS282S cam
RPM/air gap
750-950 holley
Headers

Should make a solid 450hp and capable of moving you in the 11's, deep in the 11's, with a good chassis set up. A decent size hydraulic cam would do it as well. ET is about chassis efficiency/converter and less about engine.

Have fun with it!
