Small cube? 241 Hemi?

:rofl::rofl::rofl: NO! NOT AT ALL! Exactly the response I was hoping for, and I'm not disappointed! But I did once see a 273 in a barracuda drag car that sounded like a Honda CB750 twin cam with an open 4 into one header. Blap Blap Blap Blap Blap at idle and WHHAAAAPPP!!! when they winged the throttle. Pretty sure that was a destroker build.

The super small cubic inch deal does have a place in professional drag racing. The Nickens Brothers and Gene Fulton small block pro bracket cars come to mind. But I'll be the first to point out that those engines all use very large bores, super short strokes, and some even use decreased deck height blocks. Ten and a half thousand rpm is the norm for that type of engine.

Like the early pro stock Hemi's. They were a modified 383 block. Big bore, shorter stroke than a 350 Chevy and those awesome Hemi heads. This is a Gary Ostrich block.

Bore it 4”, stroke it 4” and call it a 4x4

The Mopar 403! Very easily accomplished with a 5.9 magnum block and forged pistons because most magnum blocks still have the cross hatching. Torque plate hone to round for piston to wall clearance. Also easily accomplished with any of the 318 blocks that will hold a 4 inch bore. Some people will ask why not build a 340 or a 360, I'm one of those who would ask why not build a 318. It's fun seeing what was originally a grocery getter economy engine that average people see only for that get turned into so much more. It's about as different as I view practical to build because I've seen the results, and they are impressive! The parts are already out there that can make it happen, and probably for less than it would take to build in the small bore engine.

I could spend hours looking and measuring to see everything they did to make that work. My favorite "Mad Scientist" engine ever!
 
If I remember right there's a holden engine piston that might work with a 3.58 stroke.

Absolutely! Hell, even if it won't take the overbore, you can take a basically free teener (or 273 for that matter) block, sleeve it to 4 or 4.040 (or more!) and have a relatively fresh block ready to go for less than some people are asking for a roached 340 block that's been sitting in their garden shed for forty years that may still need all that work (and more) done to it anyway...

I wonder how much cast iron is left if you bore a 273 block to 4.040 and then another .250 for the sleeve?

yet when I saw someone talk about their 8,500 rpm 273 people were jumping down his throat with the same "Build the 360 blah blah blah" not everyone wants the same ol' HOORAH build. Uniqueness turns heads, commonality doesn't.

So install a stock 360, and tell people it is a stroked 273, I am not sure you will be able to tell the difference.
 
No reason to go with a 3.79 cause that basically gives you a undersquare 318 and a 4 for an undersquare 340. 3.58 gives you a slight oversquare, knocks peak power down 500 ish rpm which would help if your shooting for 350-400+ hp 5.0l.
 
I’m surprised at all the naysayer’s here! So what if it costs a few bucks you guys sound like a bunch of wives cackling away. I think it’s a cool project the only concern I have is the same issue the /6 has with spark timing. The small hole long stroke means you have a smaller window to fire the spark down the hole, aluminum heads would help here.
I’ve got a 455hp 292 cid 289 in my 64 Fairlane yes I’ve herd plenty of naysayers also.
Have fun good luck
 
Nothing wrong with being different,I was criticized for years about wasting money on Slant 6 engines.
I had window decals made that said,,
"You laugh because I'm different,I laugh because you are all the same."
