I am building a 65 Coronet that I was going to race in Nostalgia Super Stock. With the current block situation for gen 2 Hemis and Big Blocks I am having second thoughts and am now thinking of doing another retro looking gen 3 and just racing a 10.0 class with it. I have been checking out the Hilborn deal has anyone used one looks like they have a EFI version and a mechanical version. Any input is welcome.

No input but would love to see pics

Uchoog on here has an EFI version.

Done several and they work very well as long as they are setup for EFI. What I mean is that individual lines are run to a vacuum accumulator block so you get a good map signal (note the lines on the picture). You must run sequential injection but that's normal with a Gen III because you have a cam signal. I can post pics if you want but there's real no drama.

Both Holley and Fast offer plug and play kits now.

I was thinking of using the mechanical old school setup

On alky okay, but mechanical systems on the street never run well on gas.

This is me. Good picture find, GTS340!

Yes, I'm running it as EFI. It's quite easy to tune on the MS3x. ITB's make for easy tuning with large camshafts (though my current cam is small around 235/239 @ .050). Alex's 6.1 is much harder to get to idle.

Is there anything specific you would like to know, Biff?


The motor is out right now. I would entertain offers for the Hilborn, if you're interested. The purpose and theme of the car is changing, so I'm considering induction changes as well.

Where would one look for a set up like this?

Uhcoog I sent you a PM what are you using for a fuel pump/regulator? Do you have any dyno numbers or track numbers?

Borla and Hilborn both sell them for the G3's.

415 rwhp at 6800 rpm on a 348ci on a mustang dyno (stock 6.4 challenger with bolt ons did 402 on same dyno). With a baby 218/224 @ .050 cam.

Current fuel pump is walbro 460 lph in-tank
Previous fuel system was walbro gsl392 fed by accumulator and carter low pressure pump using a factory tank.
Both times I used a wix 33737 filter/regulator and deadheaded the fuel system

Im sure it would be expensive, but has anyone experimented with the tube lenghts and how much would it effect rpm range, torque and hp
