95 Z28 6.0 swap
This car was mine at one time with a 355 carbed and dynoed 311 RWHP and 348 TQ, nowadays, it is getting the GEN III treatment, but here is a pic of it with the LT1 when i bough it:
The work done to swap in a carb and distributor:
This was done in order to retain wiper function.
This was to retain the stock hood before a aftermarket piece was installed:
Then with a hood:
Now, trans was a T56, but it is not going to be a TH350 with a 3000 converter from Jegs, still has 3.23 gears for now, but i am not sure the rear will live forever with the new 6.0
Specs are a stock 6.0 GEN III, when we went to install a cam, what do you know, cam bearings looked like junk, so we tore the engine down, polished the crank, installed ARP bolts in the rods, checked them for out of round, 2 were, so i had a couple extra that replaced them.
New rings and bearings later, we had a goog short block, fresh.
Heads are stock 317s we ported out, cam is a cammotion grind, 238/242 @.050, just over .600 lift on a 112 LSA.
Still waiting on pushrods and will have the flexplate spacer i think tonight, we used the 1 inch Ebay set back conversion plates and the stock LT1 mounts, had to modify the block a touch to clear the bottom of the mount and grind the mount so it would not hit a bolt that mounts the adapter to the block, all on the driver side, passenger side went fine. The LT1 K member as you can assume is re used. The F body alternator even clears the PS lines with not much fuss:
This was the side the needed some grinding:
Direct bolt in:
This will be using some mac mid lengths ad Y pipe. Cannot wait to get this thing rolling again, it has been a fun car when i had it and it is going to be faster than ever.

The 1 inch set backs are to ensure the GEN III/IV sit in the location a GEN I or II would sit in so trans and exhaust alignment will be as if nothing was moved.
the are 1 inch set back on bothe sides, i used the straight up mounts in my 89 RS and the while engine and trans is 1 inch further up than stock, not that it has been a issue, bt i wish it was back where it should be.

We are hoping, we are going to use a spare converter to make sure the trans is good before we put his good one in, kind of allot of work, but the converter that we will use is a mystery, no part number, is supposed to be a 3500, but it is a 12 inch, but has a really thick mounting ring, so it could be stock for all i know.

Update with pics, got it running last night, but needs a carb rebuild and had a ticking noise for a few turn overs that is gone, i suspected dry lifters we never soaked in oil:
Had to get the 150$ truck starter, but everything went good, need to finish cooling system and get the gear selector arm for the B&M shifter, otherwise, it is nearly done.

If I may ask, what was the reason for needing the truck starter. I picked up a LY6 6.0 minus starter and have been wondering if ANY LS1 starter will work or if they are specific? BTW, the build is coming along nicely. Nice work. Eric L
