Is there anyone who knows anyone who races any of these engines? My uncle used to get big power out these engines back in the 60's (for the time)
He built several the largest a 60 over 292 with 12.5 forgings a 530 lift erson sollid roller and the heads had been opened up to a 2.02 Valve. 4bbl intake with a single 750 carb. In a 52 chevy this engine ran 13:0's NO port work on the head at all Nothig really trick. Now all things considerd by todays standerd a race gas inline 261 6 runing 13's sound like no big deal if anything a burden caus of the cost of even 108. But back then this wasnt even considerd and this engine beat almost everthing factory small block cars had to offer. And he beat alot of them. Given I know there was factory SB combos that were faster but he won 26 out of 28 (steet) races with this little thin 6 all against V-8's

He lost to a 409 in a 56 chevy My pop lied to him and told him the 56 had a 283 in it he lost by only half a fender two times. And that engine was a 261 six the 292 (never ran the 292 for E.T) they claimed would have smoked him. The other loss he claimed he broke 2nd gear. And lost to another 52 chevy on the strip.

Like I stated by todays standerd this is not impressive but imagine what could be done with todays advances there are a few links on the net one where some guys took to sbc heads and cut one cylender of each head and put them back together. I on ocason see where some one has built a 250 but not many 292's
Just a touch on a old subject some of you old timers may remember things like this.

The inline six cylinders have some advantages over the V8 except for the cubic inch dept.
7 main journals makes for a very strong bottom end.
A naturally balanced crankshaft, it doesn't depend on the "bobweight" to balance.
Getting a crossflow hemisherical type head on the engine is easier due to fewer intake and exhaust constraints.

The disadvantages are the length of the crankshaft creates issues with dampening the torsional forces along the entire length. You MUST use a good damper on these.
You also must loctite the flywheel/flexplate bolts in place and a smart man will also safety wire them.

Glen Self ran a 292 Chevy I-6 in the 70's and 80's in NHRA and set a few records, beating a bunch of SBC's in the process...

6=8 (www.cliffordperformance.net)

i got the old 292 inline six in my 66 C-10...strong little motor..tough little sucker...got it sounding like a V8 with flowmasters..lol

And fwiw, a 261" to 300"+ Gimmy, 6-banger was hard ta beat back then too!

Yes, try 6=8 and also Leo Santucci's modern 6-banger book that you should be able to buy off ebay!!

And I got my tail kicked by a hopped up '51/'52 Convert 261"er in it back in high school, me and my 2-barrel '57 283, 3-speed stick so I know!!

Next time I talk to him I will compile a list of cars he ran. I know he won two event's one in Mannassas,Va and one in Colonial beach. he said in Man they had him runing against everything. He later had the engine in a 64 chevyII but he didnt race this car as much as the 52.

Back about mid '64!!

There's an old racer out in the Sacramento area that build all his hot rods and racers with Chevy 6's. 292's are his favorite I've heard and he's played with a few 302 and larger builds. His name is Dick Bertolluci.

I think Clifford Research and Offenhauser still have parts available for them too!
Egge Machine is producing basic engine parts for them too.

Right EGGE!!!

Sorry for bringing this back from the dead. Is this the book you are talking about?
http://www.amazon.com/Chevrolet-Inline-Six-Cylinder-Power-Manual/dp/1931128154/ref=sr_1_1/002-1718290-0049608?ie=UTF8&s=books&qid=1190384995&sr=1-1

I have this book, and it has some pretty good info in it for the $17.00 price tag. I have a 250 in my 71 and plan on turbo charging it. I need to fix the electrical gremlins first though. It was turbo charged from the dealer originaly. (I know very weird) My car had a 350 from the factory, but they pulled it and replaced the 350 with a turbo L6. The previous owner lost the turbo though. Right now I have a Clifford 4 barrel intake with split headers. Talk to the guys at Clifford for some good info though. They are a big help, and the one guy definately likes to talk.

There is a way to put the OHC Pontac 6 cyl head on the 292 block.
Most OHC motors are 230 and 250 CID.

rare71,

Right, that's it!!

And I do figure that a 6 the same size as an 8 all things being DESIGNED equally the same except for piston count, the 6 will eat the 8, only b/c of LESS engine friction!!

Straight-6 vs Straight-8 vs V-6 vs V-8 sorta deal.

And a later P/U engined Gimmie V-6 can be turned into a REAL terror IF you have enough money and wanna do it!!!!!!!!!!!

IMHO!!

But that said, the old straight-6, 261 Gimmy's and up to the 292 Chevy 6-bangers in the 1/8th were hard to handle back then and even today w/ class racing!!

And don't ever sell a Hudson Hornet straight-6, flathead short!!!!!

My dad had his 250 bored out to a 4 inch bore. He is going to use 327 pistons because the 250 and 327 both have the same stroke. He got the idea from a guy who had a hopped up 250 at the dragstrip.
Joe

Excuse me if I'm mistaken, but wouldn't that make it smaller than a 250. That is if they have the same bore and stroke.

I've never heard of an OHC Pontiac 6 cyl. Do you have any more info on this. I'm intruiged.

Sure, do a seach for "ohcScott" (Sp?) and his engine!

As well as here.

And wikipedia has an article on them too...

Very interesting. Thanks.
