Looking at buying a complete 434 Shafiroff like the one below.
Its a complete package and has anyone bought one of these engines.


i never had a solid roller motor and from what i see on youtube this is a pretty good street strip engine. And takes the hastle out of buying parts,,piecing everything together,, paying a pro engine shop,,,worry about if its good..


this shop has good credibility and real good service and this is a tried and proven package..

Id buy one from them before the cheap ebay junk dealers
Anyone can turn out a mistake but overall they are known to be pretty decent
Being in Australia you have to minize your risk of having an issue and need to ship back and forth pay more the first time hope for the best.

I wouldn't hesitate buying a Shafiroff engine.

I'd like to know the specs on their "street roller" cam.

The compression is a tad higher than i can get pump gas for,,,,,yes 10.5 is ok for computer cars with knock sensors and timing adjustment is done automaticly on knocking,,,,


Because of the 8 to 12 octane number difference between RON and MON noted above, the AKI shown in Canada and the United States is 4 to 6 octane numbers lower than elsewhere in the world for the same fuel. This difference between RON and MON is known as the fuel's Sensitivity,[4] and is not typically published for those countries that use the Anti-Knock Index labelling system


The shop looks very honest and this is a killer engine and any feedback will be appreciated,,and thanks again...we love america..


i am running believe it or not a 408chev with 8.4 to 1 and it flys

10.5:1 is fine for cars with automatic timing adjustment " anti knock sensors..
we dont have them and i would prefer this motor in 10.0:1 absolute maximum


that extra 1/2 point may be nothing today but it will be in 2 years as fuel is lowered again worldwide.


Anti-Knock Index (AKI) or (R+M)/2[edit]

In most countries, including Australia, New Zealand and all of those in Europe,[citation needed] the "headline" octane rating shown on the pump is the RON, but in Canada, the United States, Brazil, and some other countries, the headline number is the average of the RON and the MON, called the Anti-Knock Index (AKI), and often written on pumps as (R+M)/2). It may also sometimes be called the Posted Octane Number (PON).

my current 408 fly,s at 8.4:1 with the cam fitted and completed..

Those are usually very well tuned when they leave
tell them requirements they will make it work
WIth a very modern chamber you can run compression these days without a lot of octance. I run 11.5:1 albeit with a rowdy solid roller and only 34 deg timing on Ca 91 pump gas. I do add good stuff when its warm or I want to run it hard just in case.(maybe 95 octane) Some cheap sources of REAL octane booster. Wth 02 kits and a quick reading of the band on the plug not like th eold days. They will take the guess work out of it. Drop it in adjust the idle and go.
Compresion makes all the difference in the world. Dont pay attention to "its only xx percent". Your throttle response, the way it "hts", idles etc are all compression related if you follow.

Concat them they can do anything you want.
10 oe 11k seems like a lot but if the tuning machining is spot on, nice parts youre ahead of the game over some mismatched Chinese crap on ebay that probably takes a ton of balancing. I wont say the name but hes very popular. EVery single one I know that bought one has had Massive failures and NO customer service. Get what you pay for most times. Helll I put 15k in my 383 carb to pan. Yup.

A 434 will me a monster on the street.

I have got to keep this engine simple and turn key..plug and play style..

i see 2 on youtube with this engine and one is a brown metalic 3rd gen car and the other a 69 in silver and red..both are wicked and sound like get out of my way type stuff..

yes tire smokin road burnin like an old funny car from the early 70, s used to do.....a very good price for an engine that would cost 30 k 15 years ago..AND THEY USE THE DART LITTLE M BLOCK not the chinese hsp block...and i am requesting manley 4340 crank and top rods....a friend i dont see much bought without consiltation from us older guys..he bought a world products 427 motown engine..it came with no paperwork and no documentation and wouldnt start..or run...cam was too big and had no cylinder pressure..what a joke and he paid 15k...like 5 years ago...

All the Shafiroff engines I've seen and raced against we're very strong and dependable. Haven't seen the their 434 in person, but other 434's were very strong. I would contact them about your fuel concerns first. I'm sure they can get it worked out for you, as long as they know before you order. They may do one with lower CR.
