86_Turbo_Hatch

Hey guys I got an 86 5.0 single turbo 70 mm. Runs 8 psi, fuel is maxed, it's got a 750 carb, 255 wall bro but the lines under the car is stock, I do also have a regulator, idles at 6psi and rises upon making boost. My question is how can I get a 10 an line to hook up to stock tank no restrictions, right to my pump. I'm looking to make 600 maybe 700. Also is a 10 an to big.

Pump:walbro 255
Regulator: idle 6psi. Steel braided from pump to carb.
Carb: 750
Stock lines to tank.

Thanks for any help.

Summit sells a new pickup with 10 supply and 6 return fittings on it you will need to swap to a external e700 or a1000 pump.

You want to make 600 to 700 what ? Horse power ?

Forget it with that 5.0 block.

I'm curious as to why you say that, explain?

5.0 blocks are known to split at 500-550WHP range.

With over 500hp rpm is your worst enemy on a stock block.
