what to get 350 Holly or the xe carb

[TY318]

ok im not sure what to go for for my 202 either the holly 350 carb or the carbs off the xe 6's has anyone had any experience wif these carbs and what would be better for my 202 iv already got 9 or 10mm leads with platinum plugs apart from that the rest is stock

[MY_84_VK]

Depends what you plan to do with the car? I just put a 350 Holley on my 202 in my VK but its had a fair bit of work done to it. Also depends if you want fuel economy, lol

[TY318]

im looking for more power i dont wanna run the stock carb tho and i can decide what carb i want

[MY_84_VK]

I went with the 350 Holley for more power and performance, now my car doesn't just start is roars to life, lol

[Baphomet]

350 holley

[delcowizzid]

stock 202 go the webber off a falcon good economy and more power good bang for buck .350 holley does work well but not straight out the box its jetted badly for 202 and you end up with the idle screws nearly right in to get them to run sort of properly .if it was worked head and cam comp etc yeah 350 it but stock go the webber

350's blow the donkey imo. There a v8 carby and even when jetted down to suit the 6's they dont work the best. Iv spent so much time effort and money trying to get mine to do what its sposed to do with out succes. There good for nothing except burning unesscery amounts of fuel.

Go the webber is that straight enough for ya ???

gotta disagree with you a bit, but also agree a bit.

the holley WILL use a bunch of fuel. no doubt. but 350cfm to run a V8 is a little on the mild side. maybe on a bog stock 253, but the minimum for a stock 308 would be around (just under) the 500cfm mark.

also, and this is gonna sound crazy, but when you have a carby that is too large you should be looking at jetting it UP, rather than jetting it down. the reason being that your AFR's should remain the same whether its a 454 or a sr20. you cant change the size of the venturies, so jetting it down will just put your mixture into the lean side, which in turn will use more fuel because you are not within your correct powerband. if its running too rich on part throttle or cruise you should be looking more towards the enrichment side of things (power valve and pump) too rich at idle adjust your idle mixtures and too rich at WOT then revisit your enrichment circuit. jets are just jets.

personally, ty318 i would go for a holley, just because they are a leggo carby and are really easy to modify by any joe schmuk. ill bet the ford carby is a better choice, but personally i would stick to what i know. but thats the problem. your asking a forum to decide for you something that you need to decide for yourself. and sorry, without a MUCH better understanding of an engine and modifications to what you seem to have, both options are a bad idea.

no offence. but i think you should buy a couple of books about engines and get the basics first before you start playing with the lungs/heart of your car.

thanks for the info and yess i know its my decision but everyone seems to have the differences between the holly and the webber i wanted to see what is better and will stay running well i dont wanna be opening my bonnet every time i head out somewhere and i know quit abit about motors to keep me out of trouble

Tripple webers are the best $$$
Triple Su's are second best.
500 holley on cain manifold if running cam extractors etc, 4 barrel carbi.
350 are gay , and flood when turning left hand corners if the needle and seats are not sprung loaded propperly.

A single downdraft weber with an adaptor plate would be much better if on the cheap, as stated.
Even an X2 manifold with twin strombergs would be better than a 350 Holley, good luck finding one of them tho.

How do i know, cause i have owned them all and know what works.

Hey Ty,

If u decide on a webber, I've got real good one I pulled from a friends XF - only done 93,000 K's & a set of headers, both of which will give a bit more poke, drop me a line if ur interested 9763 8881.

Cheers

Hang on,so you have a 100% stock/tuned and probably underpowered by factory stds 202 and you want to start at the carbie,Im sorry but thats just plain stupidity imo.The varajet will be doing more than enough for what you require right now,heck that probably overfuelling it lol.

Until you have some extractors,exhaust,manifold r/rockers and 12port head you have no need for a carberetor change,if the one in it aint broken then dont fix it.As you state your looking for more power then head,cam,exhaust,mainifold,dizzy ect will be needed first before a carb.Find out a complete goal for your engine spec wise(be a reallist please)and that will point you in a rough direction for the carby needed.I suggest you look at what the HQ racing engines use and go from there,this may be a little pricey for you though.

Also,no amount of boltons for a 202 will require a carb change.Unless internals ect are changed the Varajet in good order will be fine and provide better throttle response than all of the above when stockish.

Budget around 1k for some basic good quallity boltons before even considering the carb if you can.Do you expect to spend that sought of coin for basic rd1 mods?

[soop]

LOL, How many varajets have you seen in good working order???
They're near farked from the factory. Frankly a I'd go with the SU's can find them sitting in the mud at wreckers... fairly straight forward to rebuild too.
