Stock rails can flow plenty. I'm at almost 900rwhp through an auto on E85. Thats plenty of fuel.

I've made well over 1000rwhp on stock rails. ECS has made over 1000 on stock rails. Plenty of people have made 1000+ on stock rails. Anyone saying 600-800rwhp is a limitation of stock rails needs to lay off the crack pipe.

Or they want to sell you some fuel rails

Great point. Way too much of this going on.

Better make sure to upgrade your trunions, stock ones can't last...

I don't know about the holleys but when I had to get new fuel rails I only wanted ones with billet mounting feet so I called RSI and they had a few vette rails still laying around. I ended up with red (euwwwhhh) but their rails are artwork.

honestly though I would just use stock. only reason I got aftermarket rails is from some unique stuff with my car

I would be willing to bet the stock rails and line could support 2000 hp if you can keep the pressure up. Most people don't really understand that but there was a great write-up on here talking about it like 10 years ago

Stock rails here with Fore dual pumps. I just removed the schrader valve on the rail and bought an adapter fitting to make that a return. Car is on pump/meth and makes 850ish with a YSI.

I didn't have any issues with the stock rails but when I upgraded the fuel system I order the Holley rails cause I was already buying stuff and they are fairly cheap.
