Sticky?

This could end up being pretty cool and useful. I'll add any responses to this first post. Please post a reference with your post to verify it's a truthful claim. I'll try to keep the lists sorted by size.

OEM SB - 305
SB - 307
OEM SB - 350
Stroker SB - 383
Stroker SB - 396

Ford 418 is a 4.100 Crankshaft 4.030 bore its a 438 I believe in a 4.125 bore block. There would be a ton of these if you go by bore size....
 
Not sure where you are going with this but for sbc add 305 307 283 and 265. Was 400 on there. As for strokers there are a ton of combos based on over bore... Then there are oddball cranks. For instance a 3.75 crank is a common stroke for a sbc but GM had aftermarket 3.80 (or were they 3.85?) .... There's also a 3.875 crank....

Maybe just a list of common bores, typical max overbores and common aftermarket strokes with a link to some common engine calculators online?

We have not even started in on the LS engined yet....

Oh 289 should be added for SBF...

3.900 bore 3 inch stroke on the 289.
 
how about de-stroked combos? 377 sbc = 400 block 350 crank. Also for ford you got 393 windsor strokers
 
Not sure what you're looking for in this thread, because any V8 can be almost any displacement. Especially now that stroker cranks are so cheap and even custom pistons are reasonable.
 
I've owned the following SBF engines:

289
302
306
347
348
349
351
353
357

A few of them I've had multiple versions of. You could literally build any size you wanted...and you could build any specific size many different ways.

Other way around, you get a 377 with a stock bore 350 (4.00) and 400 (3.75) crank. A 400 bore (4.125) and 350 stroke (3.48) is 372...

The combinations are pretty damn long depending on overbore. The list might be more worthwhile if you include the bore and stroke used to get those numbers.

This can go on forever, here's a paste for a quick spreadsheet I slapped together, I only included common overbores, and I skipped small bore strokers.. don't know why somebody would put together one unless bore limits gave them an advantage. I also skipped other overbores that usually only work with custom pistons, but for example I am building a 0.020" over LT1 stroker, which comes out to 381 instead of 383. I did this to leave room for as many overbores. I would have gone 0.010" if there were boost friendly rings in that size.

It probably won't format very well, but here goes:

Adv. Disp. Bore Stroke Actual CID

350 4.000 3.480 350

+0.030" 3.905 3.000 287
+0.060" 3.935 3.000 292

Strokers
350- based 4.000 3.750 377
+0.030" 4.030 3.750 383
+0.060" 4.060 3.750 388
350- based 4.000 3.875 390
+0.030" 4.030 3.875 395 Usually rounded to 3.88 which gives you 3.96
+0.060" 4.060 3.875 401

400-Based
400 4.125 3.875 414
+0.030" 4.150 3.875 419

If this is sticky-able I can keep compiling a spreadsheet if people want to keep putting out bores and strokes. Acceptable overbores for an application is another good thing to include, like 400 chevs don't like to go more than 30 or 40 over unless the cores were lined up well, and the block sonic checks out..
