3.2 Block - Engine mounting position?

[3d914]

Just need to verify the engine mounting positions on the 3.2 ATX block for a custom install.

I have two mounting hole just beneath the A/C mounting holes on the left side.

I have two, possibly three, on the right side beneath the PS pump.

the ones you have identified on the a/c bracket are the stock mount location.

the ones you have identified on the p/s bracket are for the transmission mounting bracket. the ones that are farther out away from the engine are where the stock mount is located. you could use either for your engine mount location.

What he said.

Cool, thanks.

Unsure how it fits in your body. But this is how I solved my problems. Also motor looks real nice. Since going to use the AC I retained compressor. This is that side.

Street rod bisquit mounts. Have sleeve thru box section to prevent stress on unitbody
Couldn't use the SHO mount holes too low on engine and nothing under them to mount to unless fabricate off the K-member. Maurice

Maurice,

I like the biscuit mounts. I've got several types in mind, but will need to model the engine bar first. Here's a weld-in kit.

I also like the small interlocking mounts typically used on the Chevy V8's.

I like the way you tied your mount at upper and lower positions. I just have over a foot to traverse on each side of the engine, from motor mounts to framework. Pics to follow.

 

[3d914]

OK, here's some dimensions from my model showing the distance from the mounting points on the engine to the engine bar receiver. Over 12 inches on the left & 14 inches on the right.

Also a couple samples of engine bars used for V8's.

 

[3d914]

Maurice, your left side pic seems to be the right side with PS pump. I'd like to see the left side - and how the compressor mount fits so it doesn't interfere with motor mounts.

Tom - how do the mounts fit on the Other Woman?

 

[Shovert]

Well just found out I made mistake. I usually proof read after posting. I didn't on this one.
I posted same picture both side. Fiqure that.

Edit I went out took a few pictures of the compressor area mount. Also took a video of it. Hope this helps if not just ask for more. Since several and video it is in the build page on photobucket. Maurice

Gerard,

Here is a pic of the bottom of the mount at the frame rail. Keep in mind the The Other Woman's mounting is all rigid, no urethane or rubber at all. I'll try and find a pic of how the mount attaches to the block, but it's pretty simple. I'll also find a pic of the engine mount I was making for Another Woman; it will apply more to what you are trying to do.



This is how Extreme Performance used to do it when they used the SHO motor in their rails.

Here you can just barely make out the top of my mount.

Tom, thanks for the pics. I need to use some type of padded mount to ease any engine vibration. With this uni-body construction you can feel everything. I'm planning to use 1-1/2" sq tubing x .12 thick. This should be sufficient from what I can see there.

Maurice, do you have the part number for the biscuit mounts you used? They look thinner than those I found. I've got around 2"" clearance with my current config, but I could adjust a little if needed.

I'm working up the model now and I'll post some pics later.

Thanks

 

[3d914]

OK, here's my first configuration based on the biscuit style mounts. I'm using a 1-1/2" sq tube horizontally across the mount points.There is a 1/4" ****** welded in at each end to conform to the surface of the mount. The angled pieces are 1" sq tube up to a 1/4" plate.

The bar is installed from the front, after the engine is in position, as the back of the receivers block the bar. I can use this config to improve installation using the rolling engine test stand I'm designing. It will have a set of rigid mounting brackets that approaches from behind the engine bars position. On the left it will mount to the same points but at the back side. On the right it will mount to the two mounting holes that are slightly higher and extended.

I'll think about a couple more possibilities, but I think this looks like it will work best. There is plenty of clearance for the shift rod, and it sits forward of the exhaust headers. The centerline where I positioned the engine turned out to be precisely where the center of the engine bar would be - too cool!

I won't be able to mount the mini-radiators here though, so I hope I can get a custom radiator built. If I go with my front design, it needs to be 40" long x 5" high, and curved with a 54" radius.

 

[rubydist]

what's the wall thickness on that square tubing?

 

[Shovert]

Trans-dapt 9314. I just bought mount only. I fiqured I couldn't used rest. Maurice

 

[3d914]

ruby, steel tube is 11 gauge (.12) thick. It's well proven on the V8 installs in 914s.

Maurice, thanks for the info. Those will do nicely.

Also, I think I've worked out a configuration for the engine bar that will allow me to continue looking into placing the radiators there. The other main feature I need is to enable installing the motor, so I want the engine cradle mounts to not interfere with the engine bar. Since the cradle is used to lift the engine it will be hard-mounted. I'll post some pics one I get it modeled/mocked up.

 

[3d914]

OK, did some additional thinking and came up with another mounting option that enables me to still work for the rear-mounted mini-radiators, and also enables me to install the engine using an engine cradle design I'm modifying.

Here's what it looks like from the rear. Green is the engine bar with vertical 1/4" plates supported by 1/4" gussets. The dark red is the vertical support bar for the engine cradle, and the orange is the mounting bracket on the engine block. I have the gussets facing inward to allow space for the mini-radiators to the outside.


The right side shows four mounting holes. The two upper are spares used for the cradle vertical support bar. The lower two are for the engine bar. The cradle support attaches from the rear, allowing the engine to be move into position and the engine bar installed from the front.


The left vertical support for the cradle required a slight 1" sq. extension added to support that side of the engine when the mounting plate is removed (Two thru holes for the vertical support and two for the block with bolts form the outside). Once the cradle's mounting plate is removed the engine bar's plate can be slid into place and bolted up from the inside.


Next job is to gather the needed material and start fabbing the engine cradle and engine bar.

I love those diagrams. [If I know how to do that I wouldn't done mine] Just not use to looking at that kind of drawing. I assume [Remember never seen under hood of 914] the radiator going near rear bumper. I am just wondering with weight of motor, radiator and fluids would a front mounted radiator be better. I know more tubing, getting air to them, and ducting, etc. I am thinking in term of weight balance for the car. I am just thinking out loud. Thanks for letting me be dumb. Thanks Maurice

 

[93rev2sev]

It looks like you could just hack up the passenger side of a Gen1 SHO subframe, no?

 

[3d914]

Maurice, since the 914 is mid-engine the weight distribution is easy to maintain. With the way I'm mounting the SHO motor it will actually be better balanced then all the V8's out there because they move the tranny back an inch or so. I'm actually moving it forward about an inch.

I'm down to two options for the radiators:

1. A pair of mini-radiators mounted above the engine bar
2. A custom radiator mounted up front w/o losing the trunk.

Thanks for the radiator mounting links. I've not seen either of those. The reason these methods are so unappealing is they take up too much of the front trunk. I know it can be done w/o losing the trunk. Just gotta keep diggin.

Since the SHO motor is mounted transversely and I'm going longitudinal, I'm not sure that would work. Plus most of the SHO under carriage is heavy and bulky as needed for the car, but this needs to remain lean for a <2200# car.
