SBC 400 questions

I should have this memorized ,but I'm sure someone here will know.

Can you tell me the stock bore,stroke,
and connecting rod length on a 400 SBC ?

Thanks.

Ian

 

400 = 4.125" x 3.75" (Gen.I, 5.565" rod)

refresher for everbody: from mortec

262 = 3.671" x 3.10" (Gen. I, 5.7" rod)
265 = 3.750" x 3.00" ('55-'57 Gen.I, 5.7" rod)
265 = 3.750" x 3.00" ('94-'96 Gen.II, 4.3 liter V-8 "L99", 5.94" rod)
267 = 3.500" x 3.48" (Gen.I, 5.7" rod)
283 = 3.875" x 3.00" (Gen.I, 5.7" rod)
293 = 3.780" x 3.27" ('99-later, Gen.III, "LR4" 4.8 Liter Vortec, 6.278" rod)
302 = 4.000" x 3.00" (Gen.I, 5.7" rod)
305 = 3.740" x 3.48" (Gen.I, 5.7" rod)
307 = 3.875" x 3.25" (Gen.I, 5.7" rod)
325 = 3.780" x 3.622" ('99-later, Gen.III, "LM7" 5.3 Liter Vortec, 6.098" rod)
327 = 4.000" x 3.25" (Gen.I, 5.7" rod)
346 = 3.900" x 3.622" ('97-later, Gen.III, "LS1", 6.098" rod)
350 = 4.000" x 3.48" (Gen.I, 5.7" rod)
350 = 4.000" x 3.48" ('96-'01, Gen. I, Vortec, 5.7" rod)
350 = 3.900" x 3.66" ('89-'95, "LT5", in "ZR1" Corvette 32-valve DOHC, 5.74" rod)
364 = 4.000" x 3.622" ('99-later, Gen.III, "LS2", "LQ4" 6.0 Liter Vortec, 6.098" rod)
383 = 4.000" x 3.80" ('00, "HT 383", Gen.I truck crate motor, 5.7" rod)
400 = 4.125" x 3.75" (Gen.I, 5.565" rod)
427 = 4.125" x 4.00" (2006 Gen.IV, LS7 SBC, ***anium rods)

 

Bore = 4.125-inches

Stroke = 3.75-inches

Rod Length = 5.565-inches

Note- Main Bearing diameter is different than other SBCs - "typical" 350 etc. is 2.45-in, 400 is 2.65-in.

 

Is that list telling me which is using the early small journal crank and rods and which isn't and I'm just missing it?
And what are the #"s on "small" and "large" journal rods and cranks?
In other words, If I just pick up a bare rod, with no piston, and no bearing shells, what measurement tells me, (or anyone,) which is which?

 

Print them out and save them...All rods on 1st gen are 5.7 except 400 which is 5.565.
