Nope no type-o, check out the link, they already make a version for the conventional SBC, and one for the late-model GEN 1 87-up blocks. Are the LT-1 crankshaft different than the regular 87-up 1-piece RMS cranks? If so what is the difference, I would like to know please .

 

My question is why? Why do a 367 when you can do a 383?

Bret

 

1 pc RMS SBC is a SBC w/1pc RMS is a 87 and up all for one and one for all.







....excluding a LT5 of course

 

I did check the link, hence my opinion that it's a typo. Are you trying to tell me that on the same line that they spelled stroker incorrectly that "363" is not a typo and wasn't meant to be "383"??

"LT-1 CHEVY 350 TO 363 CID STEROKER CRANK KIT"

Boy, can't wait to get one of them steroker 363s...

Do you have any idea how ridiculous building a "363" is? It makes no sense whatsoever.

 

did I see a "hi" output pertjob job option on that site?

 

ACTUALLY Jim it makes ALOT of sence for some people. You being in the hart of Auto_X country and all I just figured you would know the rules

I got a feeling 363 is legal for a 6.0L limit class(Street Mod comes to mind) and 383(6.2L) is not

 

I've never had anything against traffic cones, so I've never felt the need to go run over some in a big parking lot...

 

If I were building a motor that was limited to 6.0L, I'd use a 400 style block with a shorter stroke
4.155" bore + 3.375" stroke = 5999.25cc
or if one of the newer Motowon blocks were available
4.25" bore + offset ground 327 crank (3.226" stroke) = 5999.58cc

Should be able to fit some big *** valves in there to move LOTS of air

 

If you're running them over then you're doing it all wrong


Ellis,

Your "feeling" is dead on, 6.0L is the max allowable displacement for a pushrod V8 engine in SM.

Dodging traffic cones (poorly) since '00

 

Ah... so you're supposed to miss the cones? Interesting concept.

I "autocrossed" when I was much younger, but it involved half ton vans and shopping carts...

 

 

363 is not a typo. They use a 3.563" stroke and a 4.030" bore. But it is an oddball combo.

If you're building to a 6.0L (366 cid) limit, why not go with commonly available parts? Like 4.060" bore and a 3.500" stroke. Or better yet, a 4.165" bore and a 3.300" stroke.

And if you're not trying to meet class-rules, why would you spend any money just to gain 13 cubes?

 

Hmmm that's my thoughts too but it's more along the lines of a 383 vs a 396.....


Bret

 

I am suprised Bret did not mention most newer SBC motors become unstable at 4.060 bore. This is a extended high RPM sport. Last time I went tach never dropped under 4,500 the entire run and was over 6,000 for most of it. noit long say 1.30 Minutes

I believe After market blocks are not allowed nore are other then stock castings.

I was just trying to point out why they would do it.

One day I hope to see jimlabs car move

 

That's true.

Hey I drive Ricers in AutoX so I can't talk, but still put up a good amount of 1st places when someone gives me a ride.
