414 Stroker?? Okay up at sonic last night I was talking with all the local lt1/ls1 guys and this one lt1 corvette owner starts talking to me about strokers. He says he has a 383 stroker....I believe that....however this winter he's going to freshen it up and make it a 414???? 
Is that even possible? I've seen ls1 cars up to 427ci...but how come the LT1's don't get that big? And also if there is a 414 LT1...how come there isn't a glamourized short block like the 355,383,and 396? Sorry about the newbie style questions but I am pretty interested in this

It just isn't done much probably due to durability issues. I would venture to say 414 is max for the LT1. The LS1 design is drastically different and is the reason for such large stroker applications. The 414 LT1 would require a lot of machine work and some of the parts are a little more speciality which would mean more $$ and why the combo isn't offered up as an off the shelf short block/crate motor. 414 cid is 4.00" stroke and 4.060" bore, pretty much maxed out.
I am currently building a 396 and it alone wraps up wayy more money than even a 383 cuz of the odd ball issues of off the shelf stuff for a 338 makes too high of a CR, so you have more custom parts....but IMO well worth the more "RARENESS" over a 355, or 383
There would also be no point to have a "414" other then saying "Hello, I have a 414". Your going to have to do a lot of work to even make that work, wouldnt be suprised if you pushed water either.

There's a place in MN I remember seeing while looking for pics of bare LT5s and they make 427 LT5s I'm 90% sure of, and that's for a LASTING motor.
427 I think is also the max on a standard casting SBC. Won't last long though with that thin cyl wall. Maybe not LT1s, but I'm pretty damn sure there were quite a few 427 SBCs back in GENI days.
