At the moment I'm running a 4 barrel holley on a 253 holden, duel fuel. I'm getting an Electric Dizzy installed today as my previous vacume dizzy has no advance.
She farts (backfires) around so much, it's driving me crazy. this happens even when i've run all the fuel out the carby b4 switching to gas. maybe a leak in the carby???
My mechanic says to change the carby to a Rochester 4 barrel with teh smaller primaries.
I've also been told a 2 barrel stromberg would be better.
she is my daily driver, and i'd like to run her on gas mostly. any ideas from anyone with similar setups?? Thanx

What Carby to use?
Pimpin', it ain't easy but it sure is fun
G'Day mate,
I have just taken a 4 barrel 'Aussie' Rochester off my 253 V8 to go EFI
I also have the original 2 barrel stromberg (which I took off to run the Rochester
)
I had the 253 with electrnic dizzy and the Rochester on an edelbrock performer manifold. It was a good setup. But I like the reeeeeally steep stuff, which no carby likes .
Dont get me wrong, the Rochester will do 99% of what you want, but for competition, I am going EFI !
So, if you wanna talk 'turkey' on the Stromberg (which is still on the original 253 manifold) or the Rochester (which was setup for the 253 ), PM me 
Dan

hey Shorty...
i have the original strom on my 253. i am pleased with the fuel econ so far. what did it cost you to swap to the EFI?
do you rate teh rochester over the strom?... how does the fuel use compare?
mine is also my daily drive...
thanks mate

ohhhhh shite... it really didnt look that deep!
The EFI swap has cost me 2 - 3 months of searching to find all the bits to convert it 
Holley wanted nearly 2 grand for the setup - then I would have had to pay for the install
Not sure about fuel consumption - but offroad and onroad performance were SIGNIFICANTLY better The Rochester is/was better in all ways ! Having driven both I would say the QJet wins hands down 
I cant wait to see what the difference is with EFI

Unhook the line gas line from the carby, connect it to your BBQ, cook some snags, have a few beers with mates and pnder over how your going to put a turbo diesel donk in your shorty.
