Title: Holly 390 Post by: Grah on April 14, 2003, 05:31:13 AM G'day Gurus,
I prattled on about the dlieghts of a 350 holly as suitable to fit to a 186 (192). Well I can get hold of this 390, which I believe is a 4 barrel, a nice polished manifold and lovely shinny filter casing. Looks very impressive and the price is right, but will it work on my 186? The motor is fitted witha bathhurst 6000 head, extractors, a mild cam, balanced bottom end, etc. Am I better to stick with a 350 or go for the 390?? Don't keep me in suspenders for too long!! Grah. Title: Re: Holly 390 Post by: weedy-burton on April 14, 2003, 08:47:51 AM Yep,
go for the 390,should have similar top end if not better and will be better on fuel for everyday driving due to nice small primarys.I ran a 350 then went to a 465 vac sec,same as a 390 but a little bigger and found it heaps better on fuel.

Title: Re: Holly 390 Post by: Grah on April 15, 2003, 01:34:20 AM Thanks Guys,
Sound like I had get the release the moths and buy it then. Is an electrically operated chock easy to change to a manual? We have got a Holly guru locally so I buy it and let him fit and size the jets properly. Thanks again. Grah. :) Title: Re: Holly 390 Post by: Grah on April 28, 2003, 04:45:43 AM Well,
I finally released the moths and bought the carbbie. Its got a beautiful CAIN manifold and looks huge. I have since been told, by local "experts" that its too big for a 186 (192). Time will tell! Apparently its got 51 / 2 jets and 4.5 power valve. Can anyone enlighten me as to what jets and power valve I should start with to see if I can get it to run?? Thanks in anticipation. Grah. Title: Re: Holly 390 Post by: Digger on April 28, 2003, 11:28:39 AM Hi Grah,
These carbies have been around since the late seventies and are a very good unit, The main jetting is right (standard for the 4160) but the power valve I belive to be to low you should try 6.0 to 6.5 these would be better suited for the holden Red 6, the 4.5Hg will open way to early and possibly over fuel the motor. And hey the work thats been done to your motor it will run fine. Hope this helps Steve Title: Re: Holly 390 Post by: Grah on May 01, 2003, 05:31:45 AM Steve,
Thanks for your advice. I'll try and get a 6.5 power valve and fit that, then try the carbie on the car. The guy who sold me the carbie said it ran like sh.t on his car, much the same engine, and I reckon it was because of the power valve. I'll let you know how I get on. Thanks again. Pic of engine attached. Grah. Title: Re: Holly 390 Post by: Digger on May 01, 2003, 02:29:23 PM geees, very nice :o ;)
Title: Re: Holly 390 Post by: Glenn 'Stinky' Stankevicius on May 01, 2003, 09:13:28 PM How do you get the engine bay so clean, oil must go everywhere without a rocker cover ;D ;D
Title: Re: Holly 390 Post by: Grah on May 02, 2003, 12:33:39 AM Whats a rocker cover????
Should there be one?? LOL. Will the 6.5 power valve and revert. Grah. Title: Re: Holly 390 Post by: Grah on May 04, 2003, 05:43:38 AM Well,
Got it fitted to the motor and guess what, it actually runs. Fitted a 6.5 power valve. Have to sort out the throttle linkage as the mechanism is all wrong with the larger carbbie. However so please to actually get it to run. Regards, Grah. Title: Re: Holly 390 Post by: Grah on May 09, 2003, 06:04:46 AM HELP HELP
Anyone know of any throttle linkage kits to enable the 390 Holley to be connected to what appears to be a standard 186 motor throttle linkage?? Its giving me the sh.ts big time!!! Grah. Title: Re: Holly 390 Post by: brads59 on May 09, 2003, 09:01:47 AM Hi Grah,
Nice engine bay. Have you thought of going with the HZ accelerator pedal and cable set up?Works a treat with hollies. ;) Cheers BRAD. Title: Re: Holly 390 Post by: nicko on May 09, 2003, 09:36:17 AM you can also use the LH -LX torana set ups
Title: Re: Holly 390 Post by: fccool59 on June 18, 2003, 12:35:50 PM sounds like your having some problems, mate if it's giving you the shits just get rid of the peice of shit, like ya grandpa probably told you, stick on the stromberg, my email adress is mljulien@optusnet.com.au if you want to sell it.
if you decide to keep it i would suggest a commodore pedal, I have a VB-VL style pedal in mine wich replaced the HZ one I had before, if you buy a cable make sure it's gonna reach as the 6 cyl commodore cable is usually to short so try to get a V8 cable, V8 stuff goes faster too, i believe the 390 is more suited to a holden 6 than a 350 becuase the 350 is to big for power low down so if some one tells you to get a 350 instead tell them to shut up. |
