I payed 500 for one with all acc and wiring, and a grand plus with some extra crap for another , one has 18k and the other in in the low 20's
and those were not really hook ups, just good deals, i plan to have the harness reworked, tuned and change the intake out to a vett intake..do the 90 mil throttle body and a few other goodies.
I want to build one or both into a 402 stoker for the work trucka dn the buggy and yank my new motor out and save it for when the stroker goes ka-BOOM!

IIRC....the 366t has the same crank as a 427...i have a 366t sittin in my shop ...was heart broken when i pulled the pan and the crank casting # told me it was a 366 instead of the 427. i was told that, that casting # is the only way to tell a 366t from the 427t. that they look identical, and only way to tell which 1 you have is by the crank casting #. since mine turned out to be the boat anchor, i've been thinking the de-computerized 6.0 is my next k5 engine.
The blocks have different bores between a 366T and a 427T, they are both a 3.76" stroke though.

oh yea, i meant to mention to those of you wondering on here.....the 409 is a bb
the beach boys sang..."shes so fine, my 409." prolly 1st bbc ever put into a roadster, and very rare, i've been told it was/is a torque monster. you will know when you see 1, weirdest valve covers i've ever seen...iirc one of the 1st tri carb motors built, right behind 327 i believe...3-2 barrels
the 402 is also a bb...it is a .030 over 396, gm try'n to squeeze more power out of engine...396 and 402 both have same crank as 427p. 427=454 block+396/402 crank..which btw is my favorite bowtie(427!)

the carb intake
that carb intake looks like it has gm cast in it, right behind what looks like the gmpp checkered flag, but the electronic box says edelbrock, i'm thinking of this swap, whats the lowdown?
different..
modern junkyard 6.0 with an eldelbork intake to bolt on a carb and msd control box.. and suprise surprise..it aint a million bucks!
power..higher rpms...aluminum heads..

409's were big block yes and had valve covers shaped like a w.

just look on google for carb kit for the 6.0, a few mags have done detailed wright ups, some also mention dyno results as well

the 366 cranks IIRC were all nitrided steel striaght from the factory.........now yank the cranks from the 366 get a regular run of the mill 454, slap the good 366 crank into 454 to replase the cast junk crank and make a hot 427.
if you wanna build domething diffrent how about de-stoking a 400...a 377 is not a comon motor and they are badass...or you could build a 434 thats a sb too...
odd SBC cid
Isn't there a 262, 267 and a 302 in there too.
how abt 283,305,307,348?,402. all of those odd numbers of engine that i have seen or heard of over the years. except for 283 305 307 i have seen alot of them. 402 is rare. but i think i have heard of 348?? maybe the numbers are wrong, but something like that that is related to chevy. as matter of fact get a 250 or 292 I6 and build it to be a racing motor. and u will amaze people if a straight 6 smokes a v8

yep i was sure i forgot other motors. but yep.
Here you go. You can take your pick of stock engine sizing of....265, 267, 283, 302, 305, 307, 327, 350, 400 on the SBC side of things, or you could go 348, 366T, 396, 402, 409, 427T, 427, 454, 502, 572 on the BBC side of things.
Ah heck, don't forget the 430,465,495,509 bb's that you will never see, and are worth there weight in gold. All factory aluminum race blocks with iron liners, very rare. worth the mention, since they just sound cool.

Theres a completely differnt family of engines you guys are forgetting about.
The 348 and 409 where differnt from both small blocks and big blocks. They have a funky valve cover as well. Heres a pic for yall to drool over.

I spotted a few more gaps in there. There was also a 454T but they are hard to find because they was the favorite engine to build the 540cid most of the early monster trucks used. And are also the base designe for merlins 540 blocks. The 6.0 was mentioned I dont know its cid for sure but i belive its close to 396, but its consitered a small block, also the 8.1 was a 497 or 498cid alot of people think they was a 502 but they are not.
Now the one that I cant explain is GMC's new 6.2 gaser available in their denali line, 416hp from the factory, that would be differnt but probably expencive as I havent seen it available in anything else.
More expencive options are Bill Mitchells custom crate engines. he offers 350, 415, 427, and 454 cid SMALL BLOCKS! Then the big block range is 454, 509, 540, 572, and 632cid DAMN! Also there is a LS line available in 427, 454, and 481cid SWEET!

If you realy want to be differnt (weird) drop one of the mid 60's v6's, cant remember what displacement but its a HUGE v6 something like 305cid? Maybe someone else knows more about them than I do, and can splain that engine. lol

i've been thinking about this
from what i've read, the crank isn't the only part to rob off of the 366t....i read that the crank, main journal caps, and rods are all worth putting in your build up w/454 block. if you use the journal caps, i would assume it would need to be align honed. and i thought the rods from 366t, would be different, due to the 4 ring groove piston. but i was told to put my 366t crank, main caps, and rods into a 454 block to make me a 427!(my fav).. not sure what pistons, heads, or cam (i'm thinking a comp cams Xtreme Energy XR276HR Cam) and then what harmonic balancer and flywheel?
guess i'm on the hunt for a 454 block and a new complete 6.0L, i do have more than 1 project! any ideas on best bang for buck building the 427 w/my crank,caps, and rods?

Now you start with swapping cranks and blocks and mixing and matching parts. A friend of mine who is a GM mechanic at the local dealership was telling me about putting a 454 crank in a 396 block to make a 427 But its a differnt engine all together because now its a small bore long stroke engine. witch he claims is a torque monster. He said you have to clearance the block the same way you would with a 383 stroker.
His story was he had a 454 and a 396 and was building both a truck and a 71 nova he wanted the 427 made by the 396 crank in the 454 block witch is basicaly a factory 427, for the nova. Then he thought that makes the 396 block and 454 crank useless, that is until he looked into makeing it work. And once he had it done, he was very impressed with the bottom end grunt the long stroke 427 made.
Personaly Im not a big block fan, and I have my own theory on long stroke small bore engines, compaired to big bore short stroke engines. I do think in theory a car built to be fast should have a big bore short stroke engine, to rev faster and gain RPMs quickly. and you cant say a long stroke dont make more low end TQ so it seams to me for a truck you would want long stroke small bore for the low end grunt.
Of corse that brings us to another engine witch has equil bore and stroke. This engine still realy depends on the stroke lenth. I mean you could have it either way, long or short stroke providing the parts where available, and depending on your desired displacement. For example you could have a small block with a 3" bore and 3" stroke and it would be a short stroke engine but tiny displacement. On the other hand you could build a big block with 4.5" bore and 4.5" stroke and be a long stroke engine and have big displacement.

heres a good link to bore x stroke chevy specs:

i agree longer stroke engines are more torque orientated....and short strokes rev faster.
best of both worlds?
i have a dirt track car that i posted a thread about the engine earlier, where i asked if a small journal 327 crank could be used in a 400 block using some sort of spacers, just like they do to build a 383.
i want the large bore of the 400 block for the power of the larger bore and the short stroke of the 327, to get me out of the corners faster. every1 said no go, but it would work if i had a lg journal 327 crank and use same spacers as a 383.
i have a sj 327 and was trying to use parts i already have, but am now looking for a lg j 327 or 307 crank to build this motor and am selling off the parts from the smj 327(some of which are # correct for corvette applications :-) )...it will need custom rods and pistons,(i believe, but may get by with 1 of the 2 being off shelf part) but would be a monster on the track..as 400 bore would produce the power and the short stroke of the 327 crank would give me the quick rev, i need out of the corners and would keep me below the 360 cid cutoff.
just using longer rods will help produce more tq, w/stroke the same....its the same principal as using a cheater bar on a wrench. the longer the rod, the more leverage the piston has on the crank, producing more tq. with the same stroke. so there are a # of different combos that can be fashioned!
i would like to try a 265 v8 crank in the 400 block, that would be a 3'' stroke with a 4.165 bore (@.040 overbore), use as long of a rod as possible to help tq #'s.
the 632, which has truly monstrous 4.600-inch bores and a lonnngggg 4.750-inch stroke, is a gm lovers wet dream! i've given alot of thought to swapping parts to build specific application motors.
i even have set down and figured out the firing order for a 350 if you could get a 180* crank. that would be when the piston on left bank is firing the piston on opposite bank on same journal would be on exhaust. only thing special, crank of course and the cam, but w/ a simple cam swap and dizzy cap, you could get the v8 to fire 2 cylinders at once, which would be a low rpm motor, but (on paper at least) it would have twice the power by having 2 cylinders firing at same time. possibly good for tractor pulling. i've spent alot of time, speculating different crank and block combos, even with custom cranks as mentioned above. any1 else ever gave much thought to making 2 cylinders fire at same time for a competition and swap cam back to have a regular firing v8? a 180* crank in a 90* block? can and where could you get specially made cranks like this?
