Nice tight packaging using the mini-Sanden. Will have to determine if that compressor will work for this vehicle. Going to check out Holley brackets too.

Thanks again JJ.

[lower50's]

Well it will be a very merry Christmas for you guys. That is some amazing news that your wife beat it and it could not be better timing. There aren't enough success story's. Wish you both the best!!

Doug please get a handle on the best LS bracket set up would you? I would like you to do all the hard work then I can come in a duplicate your set up.

Good stuff

Marc, I am off now until Jan 4 so am planning a lot of shop time. Figured on dragging my feet doing piddly stuff like hinge rebuilding and following your lead. Ha!
Ok, thanks to a lot of good input from our friends here I am thinking:
Using Corvette or Camaro accessories will put the alternator or ps pump (whichever is on top) into the left inner fender. Would have to make a cut out.
Using truck accessory I think will eliminate the problem on left side.
KWIK has an a/c bracket that pulls the mini sanden in pretty close and high so I think it will clear on the right side.
Stock a/c mount will need a heavy frame notch.
Holley has better looking high mount brackets than KWIK and I've asked them for dimensions from vertical centerline to outside edge of compressor.
Holley has a bracket for an R4 and a Sanden.
I have to determine if the Vintage Air I plan to run will work with an R4 or the mini Sanden.

So bottom line for me is...I think I want to run the truck accessories since I have them with what ever a/c will work. Still have to find some answers on A/C. And to do that I need to move my engine back and up. Figured I can stand around and stare at it with a measuring stick for a few hours or just move the darn thing in a few hours.

Here is the high mount Holley bracket.

Thank you Lower! The last year has been incredibly difficult and stressful, so I've spent a lot of time on here which helps. She spent the morning grocery shopping and all afternoon baking for our Christmas goodie plates we give away to friends and neighbors with Christmas music blasting. Awesome! God is good and we pray it stays away!

[FarmerSid]

I'll look for some dimensions too. Do you still have your inner fenders on? if so, what dimensions do you get from the crank center pulley to the inner fenders on both sides? what about the same but from the water pump pulley to the inner fenders? Cheers!

I do and was thinking those dimensions would be handy so I will get them. There will probably be variation depending on engine placement....up, down, fore, aft.

[FarmerSid]

From the few minutes I have to search. It looks like earlier Vettes (1998) had the alt up top and a newer (2002) had it down low. Still on the look out but thats what I found so far.

[Advanced Design]

Here is Camaro.

[Advanced Design]

Here are the dimensions in my Burb. The dimensions will be varied based on engine placement as the inner fenders are not squared up and down or fore and aft. You can see that in the second picture.

This engine is 2" above radiator support cross member as measured from the outside bottom of the truck balancer. Left rocker cover is about an inch forward of the toe board.

I heard back from R & D, their radiator measures 3 1/2" from mounting flange to the back of the slimline Spal fan.

[FarmerSid]

Thanks AD. That will help a lot. It's gonna be tight with the rad and e fan in there. Hope it fits perfect.

[99 to Life]

Nice specs you dug up there doug! helpful stuff, I like to keep stuff simple if possible. LS stuff is far from simple! I personally don't even like the look of full serp setups. I still like the ol' two belt sbc stuff! ironically I do like seeing coils and the modern look of an LS, just not the front of it. Its always something, I'll be on the hunt and or right in your position in a few weeks when I get engine plopped in and start seeing what the heck I gotta REDO.

[reaper71]

Really nice info Doug!
The truck setup is much tighter and cleaner look. (my 2cents)
Mark...

[Advanced Design]

Sid, thank you for doing the research too. I didn't know about the different Corvette configuration. I think working together we will all figure out what will work for our builds.

99, This information is probably in a sticky somewhere though I didn't find it in one place. So many variables here. Sometimes I think I would like to build something that bolts together without all the configuring and fabrication. We dropped an LS in a friends 65 Pontiac wagon in like 10 minutes. Would have been 5 except we had the engine mounts in backwards. So easy.

Mark, I agree on the truck set up, especially for an AD truck. Corvette is way too wide and I think the Camaro will put the alternator into the frame. Rub is the Camaro intake won't work with the truck accessories.

Thanks to a member here who pointed me to the instructions for the Holley A/C bracket to see the dimension from cl of engine to outside edge of R4 compressor is 16 1/4". I am pretty sure that will put the compressor slightly into the inner fender. Sanden dimensions are 18 1/4 inches. Tried to copy the picture to here and couldn't figure it out on this Ipad.

Here is my engine location to firewall...about a finger width. Pretty sure I am going to copy Iceburgh for firewall modification. Right after we deliver Christmas cookie trays to neighbors.

[Advanced Design]

Just for reference comparison here is the firewall modification Iceburgh did on his Burb. Biorn123 is going a similar route.

Thanks guys. I am copying shamelessly!

[FarmerSid]

There is a way where you cut a portion off of the truck ALT mount and relocate the idler in order to put a car LS intake on. Check this out.

http://www.ls1truck.com/forums/front...take-swap.html

Maybe I'm fussy but the ALT sticks up quite high above the intake.

Any chance you can try again to post the pictures of the Holley bracket dimensions?

Happy cookie drive'in!

Isn't copying the best form of flattery.?

Great information Sid! I agree, the alternator sticking up doesn't look great.

Since I can't figure out copy and paste from the pdf document, here is a copy paste of the post from another member who helped me find it.

I did quite a few little things to mine to get it to fit how I wanted it. I did a similar firewall mod, trying to make it appear somewhat factory. I took a leftover piece from a patch panel and used it to fill in the gap, worked very well.







I also ditched my stock inner fenders in favor of custom ones I made. I just couldn't stand how much wasted space there was with the originals, and also didn't want all the road debris thrown by the front tires to hit the back sides of the fenders. I ended up with a lot more room to stuff things.



Lots of room for the compressor:


And I'm left with a nice place to be able to run wires and hoses that won't be seen:

[Advanced Design]

Very cool mod's Blue Jeep! I like them!

Is the box on the left one for PCM mounting? Looks like the fabricated ones completely replaced the original inner fenders?

[BlueJeep]

Yes and yes. The PCM mounts between that inner fender and the firewall, on the driver's side. The truck harness is the perfect length to do that with, and it uses the flat s10 mount to fasten the PCM down.

Lots of room for mounting it down there:




Also lots of room on the front side for the air filter:

[Advanced Design]

Great ideas and fabrication BlueJeep. Love it!

The fabrication shop in town just installed a new waterjet. Exciting for we folks out in a rural area to have this available....so I had them cut out new frame tab engine mounts. Really, nice, clean and precise cuts.

Will someone please remind me to build in adjustability on the next set of mounts I do? I did the current mounts out of what I had in the shop. They will work fine once I get the engine in the right place. Just too much work when I need to make an adjustment because I didn't plan ahead properly.

Christmas cookie trays delivered. Wife is wearing me out...she is making more fudge tonight. Awesome! Praise the Lord!

[65sub]

I'm glad yo hear Mrs A.D. is feeling better and it's also good to see you back in the shop. Fitting the accessories looks like an interesting challenge. If everything just bolted together everybody would be doing it.
