Got a few questions about your car...
Do you have a build sheet for it?
Do you know if the M-22 is original with the car?
Does it have a metal fan shroud and aluminum radiator?
Do the brake calipers have one or two brake pad pins?

one-72

build sheet destroyed. came with m21,fiberglass composite shrould ,not sure on the brake pad pins. are you looking for the zr1.

Had to ask!
Was hoping to make your day!
Maybe make. ZR1 clone?

I've done a 68 ls/richmond 6 speed also done ls T-10/muncie swaps. Are you wanting to know tech aspects of the muncie/ls combo?

Just asking but will that M22 stand up to the LS7 if you beat on it a bit and have somewhat sticky tires?

one-72

Im sure the m22 will take it. ive had one behind a zz502 in my 67 chevelle for some time only went to a t56 magnum for the highway speeds .tires and rearend i believe will be the weak point '

one-72

I did build the m22 using an after market case that I purchased from the Gear Box co. a real nice piece extra thick and a much larger input shaft bearing .

I’m just curious for my own knowledge, why go thru the hassle of sticking with the Muncie behind the modern LS7, instead of a modern 5 or 6 speed? Nostalgia?

Bikespace

It's less of a hassle. It will bolt right up. You only need a new clutch. You Don't need a new driveshaft, trans crossmember, or $3-5K for a new transmission.

after talking it over with my son today Im leaning towards the t56 magnum its an easy install,just a little glass work.I do these projects to keep me busy and I really enjoy it.and like he said cant take it with me. and swap out the 3:70 gear for a 3:36 .1st gear in my 2013 vert with the ls7 was almost not needed for takeoff with Can the3:43 that it came with. Hard to sleep with all this going on .thanks for the input boys .Think i,ll mount that m22 next to my chair to rest the remote onn.

This will be a good setup. I swapped a LS3 / 480 & T56 into my 1978 corvette, added a 3:36 diff to match as closely as possible to my C6 2010 Grandsport.
Here is my swap info.

Changes since install, used a Tilton hydraulic release bearing part # 60-6105 and a Tilton ST246 Twin disc clutch. Tried to setup same as C6 clutch pedal. This didn't work out, clutch is heavier than a C6.
Spend some time looking at the clutch choices. If you like the feel of a C6, then you might look at using GM parts. But go with twin disc setup or the pedal will be very heavy for a rated clutch for a LS7.

LS3 / 480 Install. 2 area's of issues. FEA (front end accessories) clearance from control arm, Gas tank so you can run down to 1/8. Full. My install still has the factory tank. Works but doesn't show proper full level and cannot run on a road course without 1/3 tank full.

"it's an easy install,just a little glass work". Famous last words? We'll see how you feel later on.

Exactly my feeling, I can only take on so much before I own a project that never gets finished. Myself, I put a carbureted LS3 in my car because I figured old school car, old school solution. I didn't want to have to mess with a number of ancillary issues. The biggest drawback was I had to swap out the hood for something with more rise. Looks pretty good from most angles.

Some random info for you

Somebody long ago started this thread to which there were lots of contributions early on and then I guess everybody forgot about it. Haven't browsed here for LS7's, but if it helps you, fine

My swap was an LS376/515 and a 3:36 rear with original but rebuilt drivetrain. Lightweight flywheel and pressure plate. Rev's quickly. Original driveshaft. Great autocrosser. Clearance issues as above, all reasonably easy to solve. I have the factory tank with external fuel pump at the rear, never had a problem. You will have a very different solution .

One consideration, with the block adapters to get factory mounts, the motor sits higher and I had to mess with driveshaft alignment to get rid of an annoying vibrations.

That's the big stuff

the thread you sent answered many questions thank you .glass work comes easy to me (boat builder ) among other trades machinist, welder fabricator .this is all great fun for me.What we do will be a lost art some day sad to say. keep turning wrenches never quit .

71 Vert LS1

On my 68 C10 I swapped in a LS6 with a T56 magnum. I used a 2002 Camaro bell housing. LS7 clutch, pressure plate and flywheel. 2002 Camaro slave cylinder. Tick speed bleeder. Worked great.

Not to be churlish, but the lengthy thread I referenced (not mine) was meant to be a resource for those who would make LS conversions. Posts in these threads which quickly vanish have no lasting value.

I always thought that thread should have been a sticky.
That said, I am not sure if I am guilty of that same crime.

There was another one on swapping aftermarket seats, same deal. As a result we don't always get a more complete picture of who did what. The forum search function is very tricky to get a search that gets good results, stickies on frequent questions are better.

Sorry just my editorial comment!

shopping for headers ,not much available,American racing 12 weeks plus behind .working on billyboat now. their behind also. I assume not many of these swaps being done at this point. I would like to get 1 7/8 primarys and stainless long tubes. any suggestions?

Bikespace

I saw the Billy Boat headers:
https://www.bbexhaust.com/shop/chevy...der-fcor-0580/

I'm sure they are very nice, but $1500 for short-tube headers seemed a bit steep.

I bought these for my LS6 swap. They are, ironically for you, LS7 takeoffs. @cagotzmann used the same ones in his build.
