dollar for dollar, you can't beat a swap to a 5.3 these days. even after you buy the carb intake and ignition controller and put them on a junkyard motor, you will be right at about the same price point as a stock rebuild on a 327 or 350 and have a whole lot more motor under the hood.. i wish i had been smart and gone that route instead of sinking $1500 into a basic overhaul of the 305 i put in my 86 Camaro..

also, San Antonio was a neat city, too.. we saw a lot of history within walking distance of the hotel, and the river walk at night was one of the coolest places i've ever seen.

Years ago I built a small journal 327, bored it 30 over - stock flat top cast pistons (9 to 9 1/2 - 1 comp) with cast rings and balanced it.
Cam was Chevys 350 H/P 327 hydraulic.
Heads were camel back close chamber 194ís - had the exhausts cut out to 1.60 and a three angle valve job done.
Intake was Chevrolet aluminum hi rise dual plane unit with a 650 holly double pumper and a set of headers.
I put it in a 68 Chevelle with a four speed and 373 gears, what fun.
I would drive it to the local drag strip and with full exhaust system and stock size tires it would do consistent 13.90s @ 105 mph. It would also get 16 mpg down the road.
I built many motors over the years, gotta say this was one of my favorites, just put gas in and drive.

I pretty much had the same exact engine in my camaro with worked 210hp heads, 13.9 was what it ran, very reliable and fun to drive. Boil the tires and rev to 5,500 quick. Fun, not a whole lot of top high revs, but still fun. I like novaderricks idea of the 5.3 late model engine, a little more difficult to do/wire, but you can buy a tuned computer cheap and plug it in, alot of guys out there doing them, ie megasquirt computers.

Greetings from Arizona
When I put my wife's 67 Elcamino togather I rebuilt a 327, 202 heads, nice cam as I'm running factory ac and power brakes, with 700r4 and 12 bolt 3:31 gears it gets about 20mpg freeway

My 69 Camaro had 327/210hp, I installed GM Crate motor, 350/330hp, 700r4 and 67 Transam 10 bolt with 3:31's also gets over 20 mpg freeway

Both cars are drivers with Camaro on the road for about 5 years and Elcamino 3 years. Camaro motor cost about $2500.00 at local GM dealer and 327 cost about 1500.00 but I had heads already

Good Luck, hope this gives you some ideas, My son has a 66 Chevyll with 383, 700r4, 4:10's turns 12's street driven, but power brakes required vacumn reserve tank due to low engine vac. FUN to drive haha j

Just wanted to add that I very recently sold the 327 engine from my '68 Camaro and building a 383 over the winter. I was told in no uncertain terms that you need a 4-bolt main block to build a solid 383. I asked if we can use my own 327 for that purpose and was told, no. Most (if not all) 327s were two-bolt mains.

All 327's in production were originally 2 bolt main. But it isn't a problem to convert them into 4 bolt main blocks. Almost any machine shop can accomplish this task, not expensive either.

The 383 should be okay in a 2 bolt application, GM used the sbc 400 with 2 bolt mains lots of times.

If rebuilding the 327 keep the duration around 210-215* @ 0.050"
Go with the Vortec heads, or the RHS Vortec type heads. Get the proper intake for it.
Compression builds torque. 10:1 is pump gas friendly though it may need 91 octane. Keep your quench tight. 0.040" is great for the engine.

A CHEAP stroker is a 350 crank and pistons. 350 cranks are a give away, your rods are the same in both engines, you'll need pistons anyway if you bore it 0.30.

Go with the same heads with any size build you go with. Keep lift below 0.470" lift and the heads won't need any mods.
