main girdle

[farmerz24]

who would be intersted in a main girdle? This would probably fit the 3x00 engines, and would be around 3/8 to 1/2 inch thick. Once i pull my engine ill be making one up out of mild steel. It will be laser cut.

I will be doing this in the next couple of months and was wondering who would be intersted. The cost would probably be around 80US i would imagine.

Ive looked at this a little bit but it does seem like there is not much clearance for it. Once i pull my engine and turn it over i will let you all know, just wondering who would be intersted in this.

I am going for 450-500 wheel on the next build and dont want the bottom end to be the weak link.

your goal is the same goal i set for my 3400 build. i plan to get rid of the 3.4 and go 3.9. with the girdle did u keep a scraper and the windage tray in mind???

[farmerz24]

im thinking that with longer ARP studs the windage tray would bolt on after the main girdle. but, the windage would be lower in the pan, but only by 1/2 inch or so.

the scraper im not sure on, ill have to take a look in the 60deg6 store and see how it looks. it may or may not work. Infact, the girdle may end up being so close to the throws on the crank that it may work like a scraper as is.

anyone know what the clearance should be on the scraper to crank?

The clearance between the front main cap and the front/bottom of the oil pan before the sump may be a problem. (it gets prety shallow right there).

You may want to modify the windage tray so that the girdle and tray are one piece. This could be accomplished by cutting the outline of the girdle into the windage tray and then wielding the girdle's outer edges into the windage tray. This would leave extra clearance and allow you more freedom and simplicity in your girdle design.

PS. are you also the one who sells 3400 header flanges? If so, how much?

I know that Im reviving a dead thread from over three years ago.... But has anyone tried or had success with building a girdle for a 660.

Ive been knida curious since the idea was posted to see if anyone managed to to build one.

[geoffinbc]

I have never seen one yet. But if anyone is able to get to the power levels they claim and then see signs of cap walk then I think a girdle is on order. Until then someone needs to really work these engines because so far they laugh at every horsepower they crank out.

doesen't the oil pan kind of act like a gurdle? i thought some bolts go though the oil pan into the caps that why i can not use a RWD oil pan on a 3500?

[mfuller]

The oil pan is structural on the 3400. You have a bolt going through the side of the oil pan into the side of each cap.

This gives you an idea:

oh ok

With a decent set of studs, I dont think that the 3x00 would have any issues with 500+. Im building a 3500 motor with the goal of reaching about 530hp at the crank. (eqivilant to 450hp to the wheels)

I was just curious to see whether or not more work had beed done on this. I would definietly purchase one if it was available.
