CNC-Dude It was a real awesome experience to have been able to be exposed to such racing icons as Jim and Cotton. It also was a daily surprise to see what well known racer would walk thru the door also and go to lunch with us just like one of the guys. Guys like Charlie Lee, Sonny Ray, David Rampy, Floyd Cheek, the late Bobby Hamilton, Larry Pritchett and of course all the Labbous'....I could write a book on all the racers that came in there on a regular basis. It sure was a sad time when Jim passed. His son Sandy and myself ran around, so I think your racing days were quite a bit before my time. Im sure I would recognize your name or face though. What memories....

I got to see cotton and Jim run many times Hated to loose a great guy ,always like to see the faces on people who would run and Cotton the first time,and loose. at that time I was running a 67 Silver Dodge Coronet R/T I was running head to head with John Laboose ,Loose Caboose 68 Plymouth, JR. Quarells ,Little Scooter 64 Galaxie bring back the heads up racing ,NO DIAL IN, guess I am giving my age ,you probably already know who I am.Later in 1970 I ran a 1970 Black and Gold Duster with a 340 six pac 4 speed held track record at paradise B/SS .

I want to make this engine as strong as I can on a budget, but still have something I can depend on. Give me some suggestions on a cam, intake (4BBL or 3 carb), compression, Should I mill the head or buy pistons, ect.
I'm shooting for at least 300+ HP~ 1HP per CI
I want a good daily driver that can occasionally burn rubber, but I don't want to go the SB route just because everyone has one and I want to stand out a little. I've seen 292's that can easily do a 10 sec 1/4 mile... OH, this is replacing the stock 216 from a 1949 chevy 3/4 ton pickup

xxllmm4 Eaton m90 supercharger from a mid 90s buick or T-bird. If you have some fab skills it's not too hard to do.

Now that's perspective!

vinniekq2 I did not think 600 N.A. HP was possible with 270 cfm with only 6 cylinders? That engine I would like to see running,,,very nice
05-01-2013 12:32 AM
CNC-Dude Vinnie, the head was right at the 270 CFM mark,this is what most anyone can achieve when they install the bolt-in lumps and 1.94" valves along with basic mild porting.

cnc 292 N.A.=600 hp?

We tested (8)different cylinder head combos in various stages of porting and valve sizes. 300 HP will be very easy for you to achieve. We started with a bone stock 292 to establish a baseline, and even in bone stock trim(160 HP) yielded 300 ft. lbs of torque right from the 1800-2000 RPM on up in a straight line across the RPM range. All of these tests were done with a "pump gas" compression ratio of 8.8-1, and all parts were off the shelf components. The best HP combo was with a Clifford intake and a 4 bbl Holley carb, and all combos were still easily streetable, this combo also yielded 330 ft.lbs also. Stroking isn't necessary, and any rod other than a stock one is going to have to be custom($$$$), since it shares absolutely nothing in common with any other engine to do a swap with. Plus the bearing journal overlap on the crank is not very good on the stock crank anyway, and stroking it is only going to reduce it futher. I've built many of these engines for Comp Eliminator guys and have made over 600 HP with the 292 N/A, so you have plenty of power potential without having to stroke it. There is a guy on Inliners right now that has a Turbo 292 in his race truck that makes over 700 HP/800 ft lbs of torque, so there is plenty of ways to go to get power out of these engines.

The main key to power in these engines is in the head prep. You will have to consider large valves(1.94 intake) and removing the intake port bolt bosses and installing some bolt-in lumps. You can easily increase the flow from the stock port with 160-ish CFM with a 1.72 valve, to around 270 CFM with a 1.94 valve by doing this simple modification. Race heads can be made to flow 330+ CFM with even larger valves and more aggressive porting.
what CFM rating did that head have?
04-30-2013 03:49 PM
gearheadslife I'd think an 292 as is(solid rebuild) with a blow through turbo, or efi..
would get you over 300hp and enough torque to rip the tires off..

Excellent stump-pullers, especially when coupled with a SM465 (compound-first). Had two pickups with that combo. Now that I look back on it, I regret giving one truck away, and repl. the 292 in the other, with a 350...

CNC-Dude One of the best combos we recently dynoed made 330 Ft Lbs of torque and was 300 HP. The RPM was well below 6000. The torque curve was almost a straight line from 2500 to 4200 or so. I looked at the Engle link, but didn't which grind you were meaning specifically. I'll look back at some of the dyno sheets and see what cam we used for the best peak HP and TQ #'s we got.
