17 second 1/4 mile

that's a big call for anyone to make. to many other things that can affect the times.

Bige.

What sort of 1/4 times could you expect with that setup in a 1200ute?

all the above, but with a a14 crank & 76mm bore.all in a A12 block NO ENGINEERING, "GOTA LOVE THAT"

Valve springs oval port head oval port head/manifolds and ute diff 4.1:1 ratio and you would have a nice little toy that would rev when you wanted it but still return good economy if you stick with the stock cam

if you want a bit more fit the falcon Weber but make sure you spend the time to jet it up right or it will be hard to drive

you should be able to get the head and manifolds for a couple of hundred and the valve springs for hundred more diff probably couple hundred

pretty cheap fun good luck

Spacers are indicated if you are revving over 7,000 RPM.

Go with a mild cam for low RPM usage.

If you want a power increase over the stock cam, which means revving the engine higher, use a GX cam or equivalent (6500 RPM usage).

I recommend the stock cam. It is perfect for reliable power in the 3000-6000 RPM range.


> what's a reasonable over bore size thatd still give me some room in the future

Well since you can go 76 mm in the future, any regular overbore size is fine: 73.5 or 74.0 or 74.5. If the bore are still good, skip overbore and just hone it and new rings. (a +1 mm overbored is good for approximatly 9-tenths horespower (.9) increase).

now that sounds like the best idea! bit of decomrpession and away you go!

or save a heap of cash and make more power and still be 100% drivable and do an a12 turbo

easy and cheap! ,just did a turbo setup on a toyota 4k and it was well worth the 200 dollars spend doing it

just buy a stromberg cd175 carby or a 1'3/4 su carby and then make a j pipe off the stock manifold ,then use a carbon seal equipt turbo or even one without a carbon seal ,then theres oil line and stuff

super easy to to and goes like a shower of #OOPS# ,plus its not hard to srive like a cammed na motor can be and is still reliable is its tuned ok

we found if you use a stromberg off a volvo the jetting is realy close for the 4k and should be just the saem for an a12


cheers

well i was told that if your getting up high rpm it keeps the rockers from shifting side to side. because it replaces the spring between each rocker

hey Dion 120y sorry Im not familiar with the concept of rocker spacers what do they do to help performance?
