Hi! I'm building my first truck. Want to build street truck. 454 with 100-150hp NOS.
Now It's old farm truck: 1980 Chevrolet C10 LWB with 350 diesel imported to Russia from Finland.

I've just bought 454 with th400 from '70 chevelle. I would like 4" drop in front. What headers should I use?
Thank you in advance,
Denis.
