'58 - 348 Tri Power

['37-4D]

Holley 94's are even harder to find and get parts for,but both Edelbrock and Speedway Motors have new,more modern replacement carbs[about 900 dollars for a set of three] available.Add linkake,jets,and a 3-2 manifold,plus breathers,and fuel pressure regulators, and you're still .looking at 1400.dollars to complete your set up.One of our more "senior" members[wrench?] may have a complete W set up,already done using modified 2 gc's that I think he said would run about 1500 dollars,which would bee the best,easiest,smartest way to go for your application.The 94's were made for flatheads where 300 inches was a big engine.This where you'll trade "looks" for performance,kinda like those Thumper type cams trade "sound" over efficiency.A poor trade off,especially when you consider cost.An Edelbrock PerformerRPM small port intake new will cost you just under 400 dollars[new],and a Street Demon 625 will set you back less than 320[new],the Eddie 600 is just a little more than the Demon until you add the extra 20-30 dollars for the must have pholic heat spacer that you'll need for the Eddie carbs.You just have to decide.

Would you be able to help me find out if it is available? That would save me a lot of aggravation!!! Thank you
All this is costing me a lot more with the exchange rate

Don, my car guy says he's got lots and lots of Holley 94. Would they work?
If not your suggested speedway option will have to do.
Are you referring to these: http://www.speedwaymotors.com/Set-of-3-9-Super-7-3-Bolt-2-Barrel-Carburetors-Plain-Finish,50602.html
And if so will they produce enough CFM for this motor or should I say for my application.? Since I will probably use the motor to it's full power!
Or is that why you mentioned jets?

Yes they could be made to work for a cruiser,but they're too small to reach the potential of your 348.I'll send you a PM later as I'm checking with a couple of members about a 348 set up.If you're gonna make full power,you might want to rethink that transmission,they run from pretty weak for the units that came behind the 4.3 engines to for the ones that came behind the 2.8's.Yes,if you want to have good drivability and power,you're going to need jets for any of those 3 bolt carbs.

Thank you Don for all your help.

I have a new only ran twice Edelbrock 600 cfm 1405 4105 with hard line and chrome air cleaner I want to sell if your goin with a single carb. Also have a 409 single intake I want to sell. $400 for both.
Not sure if it was said but Edelbrock does make small port heads and I believe there is a block plate for the 58 - 59 348. I ended up parting my 59 out due to cracked block.

Thanks for the offer sycsteve, but in the thread I do mention that I'm going tri-power. Thank you though. Cheers.

I ran 3 off Holley 94's on a 60 over Ford FE 390 (401), the carbs were off a 56 Ford, each carb was rated at 185 cfm each with a total of 555 cfm, I am of the belief that the effective cfm is lower due to the triple set up.
I ran the carbs all on all off, no progressive linkage, the outer 2 carbs had the power valves removed and blanks installed, I ran this setup for 10 years with no issues, to be fair I could have got an extra 60 HP out of the engine if I went for a 2 x 4 setup, but I was after the 3 x 2 look.

Love the FE motors, also.

Now that the cat is out of the bag, I thought I'd just leave this right here.........

One of the inspiration trucks:

Still a long way to go but getting there.
Cab is getting lightly dusted now, when it gets back we are chopping away, patch parts have arrived, motor goes to shop. And hopefully by the time it's stripped and cleaned, all the upgrade parts will be here on time. Stay tuned for motor rebuild pics....

 

[Don Jacks]

No doubt about it,this truck is going to be cool when done.

 

['37-4D]

Thanks Don......I think the motor will be the main focus though!!!! Lol people won't take notice of the rest of the truck....and that's fine by me

That right hand picture about halfway down the page with the close up of the engine mount(very nice mounts,by da way),clearly shows that that head is a '58 only casting. The two small bulges in the block protruding out from the deck of the block under the spark plugs shows no coolant hole, so this is a replacement block, or maybe in late '58 they started using that block in production engines. At any rate, you're lucky. You can use any 348 or 409 factory head or an aftermarket aluminum head with no problems. That should clear up a lot of issues for you. Incidentally, nice headers! Also, what rear end is that?

Greg thank you very much sir!!!!
I checked the heads and block casting numbers. Block 872 and heads 971. I see what you mean from the pics
The rear end comes from a 1965 Bronco, it's a 9"

Here is the most recent picture of it after stripping and the custom mounts with final welds.

Little update:
Thanks to Tom Kotchtanek I was able to acquire this early '58 tri intake and 2gc carb set up.
I can't thank you enough Tom. Many thanks as well to Don Jacks for all the information and help.
There has been a slight delay starting on the motor, but I will be posting updates very soon.
