How many grounds

Just attatch it using the threads in the aluminum heads, my negative cables have been on mine for about 6 years and havent had any issues

I'm just going to attach it to the block for a cleaner look, shows off the engine a little better. I already have a 12-ga wire for engine-to-firewall, also going to do engine-to-subframe probably in 10 gauge.

@skep419 I'll have to double-check but I'm pretty sure my car still has the steering column ground. I do have the first-year collapsible and locking steering column so it might be a bit different.
