Putting the new S10 together with LS 5.3. Not a max-effort project. Cam, PAC springs, CNC ported heads, Victor Jr intake. Just shooting for around 500HP but want alcohol so we can double in a couple brackets.

While I am on here, what elec fuel pump for this combination? I was thinking #10 line with #8 bypass or is that overkill on this horsepower.

Thanks.

I run dual flying toilets. I only use a #8 to the barrel valve with a #6 return. It supplies more than enough fuel.

I have a buddy with a cathedral port 6.0, stock heads with spring upgrade, stock bottom end and small cam, running alky carb. He has it in a tube chassis vega wagon running 6.50's footbraking.
