why not a weber 32/36???

k.klein

cause im not the best with engines and holley is much more simple

Have you ever had your hands on a Weber 32/36? It's a really simple carb that gets a bad rap sometimes because it does tend to amplify other problems such as vacuum leaks, timing, and fuel pressure variances.
I can change out every jet on the Weber and have it reassembled in 15 minutes with the carb still on the rig.
It's also more appropriately sized than a 465 cfm. I believe the best Holley would only be the 350 cfm, and the 32/36 is something like 325 cfm if I recall. It could save you the cost of the Offy intake, not sure on the comparison price between the carbs themselves.

so if im buying a new intake any way .i have holley 465 cfm i dont see whats wrong with holley could some one give me a good reason. i know offy claims the holly 350cfm set up 18hp gains and good amout high and low end

JonnyBoy

Well what else are you gonna do to the engine? Performance will suffer at the low end and not be any better at the top end compared to something like a Weber or the appropriately sized Holley. 465 cfm is just too much carb unless you're putting a pretty big cam, high commpression pistons, and at least a header on.

I have a '69 F250 with a 390 in it(6.4 Liter displacement) with a decent cam in it, full 4 bbl intake, dual exhaust with no cats and glasspacks, and a 750 cfm Holley is too big for it. Yes, it's a little lower revving than the 22R, but not by much, and it's 4 Liters more displacement.

I'm not saying it won't work, but I think it won't nearly meet your expectations unless you build your engine as an all out race motor.

Edit- To answer your question about what's wrong with Holley, nothing.
To answer your original question,"wondering how well this is going to work", Not very well. You'll probably get alot of noise from air going in the engine, but the engine can really only move so much air without it being forced in like a super or turbo charger.

thanks alot you actually made sense . but i putting a carb header cam distributor intake getting the engine redone every thing . this is every thing im getting http://www.summitracing.com/checkout/cart.aspx

Both Holley and Weber are great carbs. I myself love my Weber easy to tune. I think 465 CFM might be even over for a mild built 4 banger. I think the outlaw 38/38 Weber might be still a lil over kill for a mild built 4 banger. The 38/38 flows 390 CFM. Only 75 CFM difference. I think going with a 2bl would be better. Do as you like as long as you are happy that all the that matters

BTW Link is not working.

k.klein

okay well ill be selling that then . what about 390 cfm holley

k.klein

and why does every one hate holley

Rollz79

390 would be a better IMO. 75 CFM may not seem like a lot but on a 4 banger it is. I wouldn't say people hate Holley. I myself think the weber is a lot more simpler than a Holley. Also i think the fact of wanting to but a 4bl on a 4 banger might be part of the disagreement.

Like I said do as you wish.

k.klein

just so you all know its my grand fathers truck he had it for 20 year and im putting alot of money into it in the end im looking at about 10000 4-5 just on the engine

k.klein

well thanks every thing you said helped alot

JonnyBoy

Nothing against Holley at all, I sort of lucked into the Weber cause a buddy didn't get it to run any better on his '84 Runner than the stock carb. My stock carb was not rebuildable, so that's why I went Weber and learned a bunch about them. Like I said, I have a Holley on my Ford.
Now, a bit of help, hopefully.
The advantages of using the Holley-
Probably better part throttle response due to having 2 smaller venturi opening at once keeping intake velocity up
You can get parts and jets and such at virtually any auto parts store
You will have a better selection of parts available to you(air cleaner setups, snorkel parts, spacers, etc.)
The design of the dual port Offy intake will also help keep intake velocity up for better part throttle performance
Can be converted to throttle body efi if you put the time and money into it

Advantages of Weber
Probably slightly better fuel mileage than the Holley
Don't need to buy a new intake manifold
Very simple and tuneable carb(so is the Holley, though)
There are kits and parts available to convert progressive(1 venturi opens at a time) to synchronous(both venturi) or the Weber 38 which already comes synchronous
Modifications are possible to make it operate at slightly higher angles than a Holley

Hope that helps, and we'd all love to see pics and video of it when you're done, of course!

yeah so now i think after talking to lots of people im going to go weber i save 130 right of the go cause holleys need a linkage kit and the webers are cheaper as well. plus a new intake is cheaper then the one for a holey soo im going to listen to every one and go weber plus alot more people know about weber so when i need help it will be easy . in a few weeks the engine wil been rebuilt and alot of mild mods put on her
