Solid mounts front and rear. Then you can hang a transmission off the back with a floating crossmember support or none.

The solid is better as it doesn't flex robbing hp or torque and is easy to set the engine back or over to where you want. Also cheaper and can be repaired if needed, and reused over and over again by not wearing out. But if you mount it only on them and the transmission you will need to have something flex. If not in the corners when the frame binds or twists or you will snap tranny cases. Just make sure what your rules say you can or cannot do.

Run solid Moroso #62500 and use steering tubing for the frame mount. I would not use the cheap imported Moroso knockoffs because they bend easily and are hard to find to replace if you break one also they are not an exact copy so you can't interchange them with Moroso.

Decided to bring this older post back rather than post a new one. How do you attach the solid rear engine mounts to the frame? I've always ran engine in stock location with a rubber tranny support but this time I'm moving the engine back to #1 plug to balljoint and using solid front mounts and was thinking either solid rears or a motor plate with no trans support. If anyone could post or e-mail me a pic(s) of their rear mounts it would be much appreciated.

use the flat style solid mounts on the sides of the block and a rubber mount under the tail shaft of the tranny. Just leaving it hang puts alot of stress on the bellhousing when you get hit of stuff it in the wall.

Blanep,

We just welded in ours on solids last night. We dummied it up with an empty block, hung the rear engine mounts off the side of the fram and used thick angle for the front moungs off of the cross member. I was able to set the engine back quite a bit, plus with a little sledge hammer work the distributor has about two centameters clearance from the fire wall with the cap on. I plan on hanging the tranny off the rear and not using a cross member mount. I've been told I'll not break ears on tranny's as bad with this set up. we'll see.

Using that style mount on front, but really wanting to try rear mounts with no trans crossmember for reasons that I'd rather not get into. I know alot of people do it this way without problems, just haven't ever payed attention to how they go about it.

Mikey14,

The rear mounts are actually big enough to reach the frame, or at least close to it? I just had in my mind that I'd have to weld long tubes coming off the frame somehow coming out towards the engine for the rear mounts to bolt to. Thanks for the info.

Any chance anyone could snap a few pictures of this and post them or email them to me? Always nice to have a visual of something new.

I'll look at my CD of pics when we did this (rear mounts) and if I have the pics, I'll e-mail you guys. They are too larger to post on here, sorry. What we did was dummy up a block/bell-housing with rear mounts bolted to them, bolted the engine in place, then I fabricated frame mounts and welded them onto the frame rails for the rear engine mounts. I had the frame mounts going vertical, with a thick hollow tube and nut welded on the bottom (1/2" bolts) so when engine swap time came, getting the rear mounts unbolted was a lot easier. I know non of this probably makes scense, it's hard to explain I guess.

I can take pic's but we are in a snow storm right now so it'll be a few days.

The rear mounts dont reach all the way to the frame but the rectangle tubing we used for rear mounts are only 3 or four inches long.

Hope this helps.

For those like me who are needing to see something to actually understand, check out sixwillwin's post titled 2005 pics. He has a link to his website and in the 2005 photos section of the site he has some real big pics and you can see how it was done on his chassis. Those rear frame mounts go out alot further from the engine than I had it in my head. Would still like to see others pics if you're able to get some... just to see the different ways of going about it. Thanks all.

Snow storm or not, here they are (I sent them to who has requested them). If anyone would like pics of what I have done, let me know!

Race on.

I liked six will wins pics but to be honest, he's running in a severly higher class than the car I drive. His looks more like a modified with the skin off then what I'm dealing with.

It also appears he can sit his engine back further which means his rear mounts have to be longer due to the bend in the frame rail. My rears are right near the bend, his are several inches further back then that.

Just an observation. It sounds to me like the people in this post asking about the mounts aren't running anything as fabricated as six's car.

I could be wrong though.

Wow, glad my post and pics caused some interest, just some more info, my engine is about 4" back from stock position and yes, it is pretty close to a modified w/o skins, although we still use the stock 4 link in the rear. It will be about 2 weeks until i have new pics with the new alum body. I would suggest anyone to use the 4 solid mounts and leave the trans hanging. sixwillwin

does any stores have kits for the solid front mounts, the tubes that weld to the frame. if not, how long do they need to be. i am currently running stock front mounts and a solid transmission mount, and would like to change to this setup. any help is greatly appreciated.

Hamilton: Just get a set of solid front and rear mounts from Speedway, Jr Motorsports, Midwest, ect. The rears mount to the bellhousing where the bolts go into the back of the block (two bolts each side). Then just fabricate the mounting "pads" that weld up to your frame rails so there is somewhere to bolt the rear mounts up. It's not that hard really, just kind of depends on what you have laying around for steel stock so that you can make the mounting pads.
