| | | | Joined: Sep 2004 Posts: 201 'Bolter | | 'Bolter Joined: Sep 2004 Posts: 201 | Looking for some info, I got a early Chevy 292 inline 6. I want to beef it up and put it in my 54 chevy truck with a NV4500 and 3:08 rear. I want to get the most power and economy out of it. So far im wanting to bore it 60 over (brings it to a 301), RV cam, it has a 8:1 compresion and i want to at least bump it up to 9:1. I have fuel injection for it, offenhuser 4 bbl intake, full length dual headers.
Ive never build a motor before and this is just an idea that i have. If anyone has a better idea or a better way to build this with great power and economy for street use please reply. | | | | | Joined: Sep 2006 Posts: 2,393 Shop Shark | | Shop Shark Joined: Sep 2006 Posts: 2,393 |

Buy it! | | | | | Joined: Dec 2008 Posts: 319 Shop Shark | | Shop Shark Joined: Dec 2008 Posts: 319 | For any build, make sure everything inside is clean, properly lubricated, clean, properly torqued, and clean. And oh, yeah, did I say clean?
Stuff on the outside can be changed relatively easily, but you don't want to have to go back inside, after squishing gaskets and putting on a nice paint job, just to fix something that shouldn't need fixing.
I'd go with a Holley 500 carb and cast iron headers. I think the limiting factor will be head flow, so you might consider some port work, to enhance the cam. FI might give better mileage, but I don't know much about the setup.
Good luck, and have fun.

If you can't fix it with a hammer and screwdriver, you need a bigger hammer.1965 Chevy C10 | | | | | Joined: Sep 2004 Posts: 201 'Bolter | | 'Bolter Joined: Sep 2004 Posts: 201 | So this sounds like a good build? Sounds OK to me. Im sure i will be doing some extensive work to it. | | | | | Joined: Nov 2002 Posts: 1,002 Shop Shark | | Shop Shark Joined: Nov 2002 Posts: 1,002 | All the previous is on target, especially the clean.
The fuel injection you have is a TBI?
Federal Mogul natural gas pistons will get you a little over 9:1 compression.
Starfire4 is right on with the head being the limiting factor. Another limiting factor is getting a quench in the combustion chamber.

All I can say is as I leave the V-8's behind is "C ya later!" This thing is fast!. I shift it a 7,200 RPM's and it just keeps going on using a triple intake with Weber carburetors (expensive but trouble free) and a set of custom made headers. How many old '32 Chevy's do you see run all day long at 70 MPH on the Freeway?

So, those were your pistons I ran over on the freeway? | | | | | Joined: Sep 2002 Posts: 158 knuckle head | | knuckle head Joined: Sep 2002 Posts: 158 | The drag race 292's rev much higher than 7200....But drag engines run for very short durations and get frequent tear downs. An inline 6 can beat any V-8 that has less power  A 292 with less than 250 hp is somewhat easy to build and is mildly expensive.More power than that is much more expensive. | | | | | Joined: Sep 2008 Posts: 130 'Bolter | | 'Bolter Joined: Sep 2008 Posts: 130 | I picked up the special collector's edition Hot Rod Deluxe, best of the best.

Good luck Beast I wish I could hear and see it run. I'm doing some head work with gasket matching and have talked with Larry in FL http://www.t6racing.org/ about him doing lump ports on the head, but that's a winter project(maybe). I'll send a pm as i progress.

I have used Sissell's for years now. Every head or inline OHV engine they have helped me with is an exceptional performer. Good luck.

Do you have a ballpark figure of what the head work costs? I have a 292 in my '63 Chevy II. I am running a Holley 390, Offy intake, cast iron headers, and a schneider racing cam (264h). I'm told that with the stock head, it should be making around 210hp and 290 tq. For $800 in head work, I'd be at 250-260 hp and 325 tq. Here are some pics: 292 in a '63 Chevy II | | |
