<IMG SRC="smilies/question.gif" border="0">Has anyone put the Offenhauser intake with a Holley carb on their 258? Is this thing worth a damb? Are any of the Holley 4-barrel carbs better then the Carter BBD I'm currently running? How are they off angle? Any near as good as fuel injection?

i ran this on an old 258 i had.. i loved the setup.. the holley isnt that great off angle.. even with the tric kit.. but.. i still enjoyed it.. just had to pigeon toe it.. <IMG SRC="smilies/biggrin.gif" border="0">
the holley was still waay better than that carter p.o.s!!!

So only one guy from NC has bought this thing? I would like more than one vote before I spend the money. Help!!

How about Holley carbs in general? I've spent the last 3 years dick'n with this Carter BBD, I don't know what others might be like.

Jeepgod: When you say "pigeon toe it" you mean tap the pettle a lot? Did the Holley carb stall out on hills & angles every time?

I think you'll find that the average POR poster doesn't spend a lot of time working on 258's. Most around here tend to favor BIG displacement.

I however am running a Clifford 4BBL intake (very similar to the Offenhauser) with a Weber replacement carb. From what I've seen/heard, Holley is great for street applications, but not so hot offroad. If you are looking to spend the $$$ I would say slap a Weber on it with a fuel pressure regulator.

Had I to do it over, I would probably have opted for a Motorcraft 2100, but that was when I was young and stupid in the ways of the junkyard swap. I have since grown more <IMG SRC="smilies/massey.gif" border="0"> in the ways of the force.

258's not a bad plant, makes a lot of torque.. but its heavy.. if you can go with a 2100 or maybe a quad.. avoid the holley for offroad IMHO.. course I run a v6 with a quad *shrug* I do have an offy intake though.. sweet <IMG SRC="smilies/biggrin.gif" border="0">

The Holley is hell offroad. A tricked out Holley will never run as good as Q-jet out of the junkyard on a hill.

For best results run the Q-jet wrong way round on the intake. This makes hooking up the throttle a bit of a pain but '82 crossfrie injection 'vettes will yield you a throttle cable about 2 states long that should work to make it all good.

I run a Holly 390 4bbl w/ Clifford intake on my 258. it did stall occasionally on steep uphils @ idle when I only had a 55:1 crawl ratio. no problems on sidehills. With my 102:1 ratio it very rarely stalls. I made no modifications to the carb.
