My 273 in my 66 Barracuda. When I put the vintage Offy intake and Holley carb on it, I couldn't use the super cool stock air cleaner. So I bought a black crinkle air cleaner and a 383 commando pie plate from Mancini Racing. Then I had a local sign shop make a 273 sticker to go over the 383. Not OE but I felt like it is a respectful representation.
What are the specs on that 568hp stroker? Those are the numbers I'm after.
I asked the builder for a reliable high-performance street engine that runs on 91 octane, and has a smooth idle.
0.060 over magnum 360 block. 4.125 stoke crank. Crank is made by K1, but I don't think K1 makes that stroke any more, so you would need to find another manufacturer.
Ported Eddy magnum heads, 308 cfm at 0.50 lift.
10.2:1 compression ratio.
Molner rods. Diamond pistons. Hastings rings. Morel lifters.
Indy intake with 1" carb spacer. Holley 1000.
TTi 1-7/8" headers
Comp hydrauilic roller. 0.586 in/ex lift with 1.6 rockers. 112 lobe separation. Durations at 0.50 lift are 242 in/248 ex
MSD ready-to-run distributor. Best HP was at 31 degrees timing
568 HP at 6,000 RPM, 545 Ft-Lbs @ 4500 RPM
Just for fun, we also tried some other intake/carb combinations: Eddy air gap rpm with Eddy 800 carb produced 534 HP and 544 ft-lbs . Eddy air gap rpm with Holley 1000 produced 550 HP and 559 ft-lbs.
Wow - through exh manifolds to boot!! That's just awesome!!
Here's my 318 - bored +0.060", 9.8:1 comp, KB167 pistons, prepped factory rods with arp bolts, reground factory crank, windage tray & baffled sump. Alloy heads with minor port clean up/bowl blend and good valve job, 1.6 ratio rockers with B3 kit, cam is a howards SFT [email protected]" & .574" lift. Ported weiand action plus intake and 650cfm AVS2.
@RogerRamRod Here is a pic of one of our "off the shelf" RHD headers - options are pretty limited

Up till 2:00 am with the engine hoist so I could close the garage door but my 360 crate is in its dirty home(71 Demon).
Just have to put all extremities on.
Should make a fun little s#!tbox.
Small blocks in A bodies rule!

Long time viewer... first time small block.
Working on a 65 273 to replace the 225 in my 64 Valiant (Yes, those are B-body exhaust manifolds...engine came out of a 65 Belvedere)

This is the 1970 318 in my Dart. As a kid, I set it up with a competition cams 268H, single plane intake and Holley 750, and 360 J heads. Not the optimal combination for power, but it was still fun. Hopefully I get it running again!
All those mud dauber nests ought to make that fun to work on...if anybody's home!

X block, 436”, W2, made 652 hp and 590 tq. Should have never sold this engine.

Correct it’s cruise control, I’ve installed a few of them now.

I added CC to mine as well, but I used factory stuff.
Working on a plan to use the original turn signal stalk and CC buttons when I do my G3 swap so cruise control works like it does in a 2009-10 Challenger without a module in the engine compartment.

I am seriously impressed with some of these engine bays. Some of them look like there are zero wires, very clean
My current Dart looks like it has enough wiring for 3 more cars

Work motors
Mine are never pretty but they run pretty good.
