Inline fuel pump

[walkmang]

My build is almost complete and im looking for some advice on a fuel pump and pressure ratings. Still need the pump, pressure regulater, and blow thru carb. Any advice from you gurus is greatly appreciated. Stock 4.1 with 86-87 turbo setup

 

[WarWagon]

Any 255lph will be ok on this build. Pressures will be low enough to keep volume up for a carb.
Mallory 4309 or equivalent for FPR.

How is the ignition stock?

 

[supstanman]

Yeah stock, a good friend gave me the info on changing the regulater to a four pin.

I think you can get Holley carbs already set up for blow through and E85.

 

[supstanman]

Do you know any good low priced ones

 

[WarWagon]

Low price is not something to be found in performance. Especially something as precision and fine tuned as a HP carb.

 

[walkmang]

Where should I start looking and who should I stay clear of

 

[dr_frankenstein]

what are you controlling your timing with?

I would do home mods to a holley first. devlop some kind of baseline before jumping to an expensive HP seires carb.

 

[walkmang]

standard hei dissy

 

[dr_frankenstein]

I see your using a standard HEI... But how are you controlling the timing under boost. It will need to retard under boost

 

[supstanman]

Recommendations accepted, don't know, New waters for me

 

[walkmang]

Warwagon, are running HEI with any type of timing control

 

[WarWagon]

I am using a Mallory Digital 6 control for timing now but in the beginning I used only the 4 pin module and let the VR sensor do the retard control. It would work for boost up to high teens like that, with 19* initial ignition timing.
