Was the block decked significantly... how far were the slugs in the hole? Good TQ numbers down low where it will spend most of it's life.

Good solid engine. In a decent chassis that would run mid-high 12's all day long in the mid 100's mph. Had a similar 360 build with a XE268h, LD and 750DP and it ran 107.5 IIRC in crappy air in Las Vegas. 350hp/400tq
Go have fun with it!
Post is very encouraging as I'm hoping to match those TQ numbers down low, my heap spends most of it's time booting around town or on the highway. I don't wind it up to more than 5k rpm very often... no need. Rev limiter is set to 5500. So max HP not a concern for me.
I'm up at 5k ft. elevation and it's possible I might hit it with EFI. Getting and keeping the carb dialed in can be a chore. Seeing the diff between the 2 carbs is very helpful. I have a 750 DP I pulled off my 390 I was thinking of tossing on to see if it made a difference. Not going to bother now. OP just saved me some tuning time.
I'm picking my ride up from the transmission shop on Monday, 727 was bleeding. My 360LA has the midler 268H cam (.450~.450) and less duration @.050 to boot. Will be replacing the original cast heads with a set of Speedmaster 63cc closed chamber, 1.6 ratio Harland Sharps rockers (will add .030 lift)and an Air Gap intake topped with a 625 Holley vac. sec. carb. CR should be just under or at 9:1 with a stock thickness gasket.

If I can come close to the numbers in the OP's build I'll be very happy.
The engine I posted was done on the dyno at about 5300.
The block was not decked at all. The pistons were .050 in the hole. 10cc 4 valve reliefs. Heads cc'd surprisingly low at 67cc I believe. Stock early 1971 360 heads.Was the block decked significantly... how far were the slugs in the hole? Good TQ numbers down low where it will spend most of it's life.
How was the block deck height? By photo looks like deck surface didn't have to be machined.Thanks again for posting up your 360 build and dyno test results for us all to see.
I can see doing a build just like this for the stock compression 360s.
Nice Results

This photo of the Silver 360 is a stock deck height, with .030 over stock style pistons.
I noticed that there isn't much activity going on, no new questions and no comments on anything."Stock" seems to be a relative term with 360 LA blocks.... I've read of measurements on untouched blocks from .050 to well over .100.
I've always liked the factory original cast pistons. Very heavy duty. They will take a lot more abuse than they are given credit for. Especially "those".Stock 360 Truck Pistons
Notice the heavy duty wrist pin support castings with the large oil holes to provide lubrication to the pressed on wrist pins.

Are the stock pistons dished?
Yes stock pistons are dished. 1976 360 here out of a '76 W200 truck.

Believe it is an 8.0 - 8.5:1 compression ratio piston engine.
