Bill,

Thanks for the link, looks like a neat installation. Re the driveshaft angle, I guess when the car squats under acceleration, the d-shafts would be pretty straight..

I assume then that a clutch housing & adaptor plate are available from DRB?

Julian,

DRB can supply everthing from soup to nuts
if you want. In my case, They are supplying
the adapter plate, clutch,throwout fork,
throwout bearing, pressure plate, pilot bearing w/adapter,ring gear, flywheel and starter. The other components, slave cyl,etc., will already be fitted to the car
when it arrives here in 3 weeks.

Bill,

What ratios are you running in the G50 (standard or modified to the G50-50)?

Any idea of what the G50 and the adapter stuff costs from DRB?

thanks,

 

[Bill Bayard]

Mike,

I have the standard gears in my G50.
The adapter plate and associated costs are
listed below in Australian Dollars(AUDx.515+/-=USD)(DRB figures of 7/2001)
Adapter plate: $540
Throwout fork: $356
Throwout brg: $292
Flywheel: $616
Pilot brg: $ 80
Ring gear: $287
Clutch: $358
Pressure plate:$592
Roughly $1600 USD for all.
I don't have their price on the G50 itself,
as I sourced one here in the States.
I hope this helps.

largest stroker kit i've seen for a 351W that would run pump gas (10:1CR) is 428. siamese bore blocks are nascar blocks (read: clevland)

 

SVO / Ford Racing blocks that can be bored to 4.125 are siamese bore. There is no water jacket between the bores, and more room to achieve a larger diameter cylinder. There is some net horsepower gain with the larger bore, claim most engine guys. To my knowledge, the siamese blocks are all 4 bolt mains. The 351s are available in both 9.2 and 9.5 deck height. The 302 are available in 8.2 and 8.7, to the best of my recollection. Most of these blocks require final machining, bores, mains, lifter bores, etc. They're great, will hold up to a ton of power, but are not cheap.

As a point of interest...the largest displacement engine does not always yield
the most powerful engine. There is a tradeoff
in the rod ratio (max rpm) vs the additional
cubes to be had. Depends on what type of engine you want...a 9,000 rpm screamer
or a 6,000 rpm torque monster.

And that's just for naturally aspirated.
When you toss in power adders (blowers,
turbos, NOS) the combinations are mind boggling.(as well as some of the price tags)

If it's any indication; I raced a modified GTD40 with a G50-50 box with the addition of an oil pump and a Quaiffe straight-cut gear set without any transmission problems for 3 years. http://www.quaife.co.uk

 

Hi RD
here is the photo of an engine with Gurney heads. I think 400 cu/in is plenty for the street.
I just got back from Hamburg Germany with a ZFDS25/2 tranny 3.77 ratio.

 

 

 

Sorry 1 last time

 

ZF DS/25/2 gt40 Bell housing

 

Has any one got a GT40 top plate for the ZF25/2 box with the two mounting points? If so please e-mail me
