Great, thanks Scot. Did you see my post that I am using the hooker ls swap headers with 1" setbacks mounts?
Yeah I did, thanks, that's awesome. When you get a chance, can to take a pic of the passenger side to show me how much room is between the motor mount towards rear of the car until the headers? I need to move that side motor mount back to allow me to put AC compressor down low. It's a b!tch since I have Vette accessories & motor is 1" back. Trying to add supercharger, & want to use OEM belt drive, & I dont want to push motor forward.
Yes later today I'll get a couple pics. I'm using the stock 305 mounts with ebay adapter plates, not sure what your using but mine seem pretty bulky, but were cheap and do the job.
Who has BRP 207-1302-00 motor mounts? Anyone have them still in the box? Need some pics/dimensions please.
Thanks
I am using these MetalTek mounts with the Holley 302-2 pan. They don't give quite enough room for a low mount compressor with Corvette accessories. I also want to use a supercharger, but I don't think I can notch the crossmember because top bolt on the mount is so far forward. Below is the passenger side mount. Those BRP mounts look like they might work.
Here is a dark picture of the passenger side mount installed.
Scot, here’s a couple crummy pictures. If you use a simpler mount you should be able to slide it back an inch or so from where mine are right now. I had to clearance to stock clamshell mount to clear the #2 primary because it pulls in so close to the block.
I like the price of the Metaltek ones much better than the BRP ones, $119 vs $299. I have a piece of paper I used & then colored over it to find the hole edges. I'll get some dimensions of it tomorrow & work on my own mount design. I'll post some pics. Thanks all for the pics.
Here is a pic of the right side BRP mount i found on the internet. I'll make something similar to it.
You can also re-position the stock clambshell mount further back on the crossmember using the existing factory holes that are present. This is where the clamshell mounts are attached when using the Hooker G-body engine brackets and it should create enough room for the notch to clear the low-mount A/C compressor installed at the Corvette offset.

i have purchased both the hooker G body mounts and the low mount AC bracket, at the Vette spacing either the AC comprwssor or bracket hits the motor side motor mount bracket.
That is a bummer...so close. Can you move the clamshell further back on the frame and make a new engine side bracket that emulates the design of the Hooker bracket?
Did u try the dirty dingo low mount Ac bracket? If the compressor is hitting now , it would probably be the same. Hard to tell from pic. You can use the Holley spacers on the factory corvette alt/ps bracket to space out to f body or truck. Swap out the balancer/wp then you could use the low mount Ac . This is what I did . I have a whipple 2.9 /ly6 in my cutlass with low mount Ac
That would be a good way to go also jimmyg, the Holley low-mount A/C compressor will definitely clear the G-body frame at the F-body spacing when using the Hooker engine brackets. That set-up is currently on the Holley Monte Carlo SS.

That was my first thought too. I think I will make a new frame side bracket too that is narrower than the OEM style, that will give me more room. Then I'll put these on & weld were they fall.

Agree, whatever mount I use the compressor will be in the same position front to back, so frame notch is required. Problem is that the frame side mount it in the location where I will need to notch. Doesn't help that I have 1" setback plates currently, trying to avoid moving engine, then I'll have to redo exhause, driveshaft, shifter moves yada yada yada. I thought about moving the Vette brackets forward with holley spacers & put everything on the truck spacing. But trying to put LSA on it & decided I don't want all on one belt.
I think the most straight forward method would be to attach a 4th-gen F-body mount to the engine and build a bracket up from the frame to attach to the mount. The 4th-gen mount is centered over the 4-hole pattern on the block, so it should give you the room you need to clear the A/C compressor.

That is a thought I had too. Do you think there is enough room for the Hooker headers to fit if I did that?
I found an idle LS engine on a stand and performed a quick mock-up of the Hooker G-body right side header and a 4th-gen F-body engine mount...it'll work for you by just trimming the top edge of the mount down by about 1/4". Once that is done, it will clear everywhere else by a mile.

Even keeping the 1" setback that it is currently at? Thanks for checking.
My answer pertains to the clearance between the header tubes and the 4th-gen F-body engine mount only. I can't say how well the mount will be able to be picked up by a bracket coming up off the frame as I have no ability to mock up a car with this particular combination of parts. You could get a cheap aftermarket 4th-gen rubber mount from an auto parts store to check the fitment and return it if it happens to not work out in the car.
Ah gotcha. Not sure what I was thinking in relation to the 1" set back. No matter where it is, the motor mount to header clearance is the same. Cool, thanks.
