Is this good Compression and Cam Specs In my 360 Engine? Please see pictures. I purchased this engine and the guy said it was rebuilt two years ago. Does the compression seem like the engine was built 2 years ago? Thanks

I say that is really good on the compression % differance between cylinders. I would think it is a possible rebuild.
Cam is about a 4 bbl 360 spec piece.
Jmho
 
The compression numbers look good, but will probably come up some once it's running again & the rings expand back to the cylinders again after sitting.
 
110* OVERLAP? Are you sure that's right and not LSA?

But yes, the cranking PSI is good and even. All the cam is, is like an Edelbrock Performer.

So I put the engine in my Dart. Seems like it doesn’t have much power tho. I stomp on the gas and it takes a little while to get going. I Definitely can’t burn the tires.

If that overlap figure is correct, that's a lot of your issue. "Where" is your initial timing set?
 
you got lucky run it
Edelbrocker performer costs the least and sells for the most
performer is an oxymoron
but worth changing???
one thing to check is to see if it is degrees in correctly
ONCE you get spark advance and carb tuned
some advance that cam degrees which picks it up some but hurts mileage no free lunch
you could advance it 4 degrees and see if it makes any difference
if it does then get a cam 8 degrees shorter with more lift
I have no idea where that overlap came from cam card or measured I have all the specs on Edelbrock cam but they changed from single pattern to dual pattern so part number would help
you can check the .050 cam timing with a degree wheel and a dial indicator
check with me or slantsix64 or others before you do it
 
The compression looks ok, that engine needs to be tuned in...

There's no way that cam has 110° overlap, that 110° has to be intake center line or lobe separation... That cam is slightly smaller than a stock 340 auto cam... .429/.444 268/276 44 overlap....
 
does it have a 2.41 rear gear and stock converter? does it idle real smooth with high engine vacuum like a 114lc

What teringer said.

If you don't know what rear gears you have, that needs to be the first thing you check. Not gonna be quick off the line with 2.76 gears.
Also, what torque convertor? You don't need a super high stall converter with that cam, but a low-stall stock 360 2-barrel converter won't help off the line either.

Yeah, the compression numbers are good; good cuz they are even and that is all .
Take it up to 3000rpm in second gear, put some toe on the brake pedal and feed in the gas. Record both the rpm and roadspeed simultaneously.
Then, take it back to whatever roadspeed you recorded, and mash it. Now tell us what the power feels like.
