Inline 6 question for you
Got a question and I am hoping not to take too much crap for it. Would a 292 crank fit in a 250 block? Is the 292 a "stroker" version of the 250? I am looking in to keeping the 250 that is in my truck just to be different, but wondering also if I could get a few cubic inches out of it.... Let me know if this is possible or if I am just sniffing glue. Anyone know where to get a reasonably priced gear vendors overdrive?
Josh

Re: Inline 6 question for you
The 292 has a taller block to accomidate the stroke of the 292, so I don't think it would work. I could be wrong...it wouldn't be the first or last time
![]() I have no clue on the gear vendors stuff. Sorry. Mike

Re: Inline 6 question for you
There was such a thing as a "cheater 292". IIRC it was a 250 block overbored with a 292 crank, and possibly custom length rods and special pistons. It is prohibitively expensive to machine it, I hear. The main reason was to bend some racing rules so you could get more cubes on a STD-LD block if the taller [292] HD-TD block was prohibited by class rules.
You could get a clearer answer over at www.inliners.org (I never saw one, just heard about it on the Inliners board.) But you could bore out a stock 250 block to .030 or .060 and come up with an aggressive 266 CI... Check out "Chevy Inline Six Cylinder Power Manual" by Leo Santucci. He's got a lot of tricks in that book.

Re: Inline 6 question for you
I saw something like that on ebay just the other day (a 250 which had been "stroked" to a 292).

Re: Inline 6 question for you
Santucci's book is what you need for building a late model six. The biggest obstacle is getting them to breathe properly. The head design is horrible. You need a cross-flow head, but most can't afford the 2-4 grand for one.
I will warn you, building a six is costly and addictive.
