Slant 6 engine builder in Ca?

Smaller engines and inline sixes in general like lower gears, so you got the right idea. I'm going 4.10 ultimately in mine.

10-4! should I just go straight to 4:10 than? What Rpm would I be at going 70? Either way only going to be in the highway max 10 min.

where do you get these gears at?
