Thread: 62' 283 Biggest cam???? how can i get more power?

Tweet

I'm building a 283 as a budget motor for my truck until my monster big block is done. The 283 is a very versitile engine, and while I'm no expert on them, I know quite a few people who have worked these mouse motors from one extreme to the other. Right now I will be putting on a Edlebrock Performer RPM AIRGAP Dual Plane Intake, 500CFM Edlebrock carb, comp cams Magnum Hydraulic flat-tappet cam with 224 duration at .050 and .470 lift for both intake and exhaust. A friend of mine built the exact same setup, and was making 360hp and about 350 ft/lbs of torque one the stock crank rods and pistons, and he also has done nothing to the heads and hasnt noticed any problems with running unleaded gas, and he pulled the motor apart at 35000 miles. This is just my 2 cents on this situation.

[B]That cam was originally in a 265 punched to 301 with a set of heads that matched double humps. And yes, it had one hell of a rough idle.

I should leave this alone but I cant! Were You casting your own blocks back then? A 265 could just barely be bored to a 283,and a 283 could just barely be bored to a 301. A 265 bored to 301 would have been bored .250. Dont think so!!

What is a set of heads that matched double humps?

I didn't build the engine. It had a 327 crank in as I was told and the guy that built it had done quite a bit of work on the heads and I've still got the cam.

one of the biggest mistakes i see people do is OVER-cam 283's

Go ahead build it....but

Parts are gonna cost more....but what the heck....You Will need more converter to get this going but you can and save a little mileage....

when I did my first 283 I used a Cam Dynamics 495 lift 280 duration cam... I also used 492 heads and flat tops and a re-worked Q-jet....I use a 3500 stall conv.

I also helped a buddy build a 350 with a Comp Cams 292 cam (501 lift 292 duration) and stock 882 heads and flat tops

My car was a 4door 57 chevy with 3.73 rear gear and his car was a 68 pontiac lemans with a 3.73 rear gear....we both used the same converter 3500...

Most times I could pull him by a car length...I was a 1/10 faster in the 1/4....

Being a heavier car and a smaller motor....hum musta been magic...

if thats was true it would have been magic.

Go with the 283, 350 horse 327 juice lifter cam, and aluminum manifold. With the Power Pack heads and decent springs, that thing will rev like crazy and stay together.

No magic here! It doesnt take a rocket scientist to figure this one out.
dr bowtie. You had the better heads and more compression to go with your big camshaft. 3991492 (492) 2.02/1.60 valves ,proberly no more than 68cc's. used from 69 to 72. Compare those to 882( the biggest junk head chevy ever made)Thin castings,most had 1.94/1.50 valves and 76 cc's .Your friend would have picked up by using a smaller cam with that combination .

64 Bel Air, 69C-10, R Pope , 27RAT and M1-2600 are all on the right track for what You want to accompolish with your 283 on a budget.

A 327-350 cam is 222/222Dur @ 50, 447/447 lift , 114 lobe center

Check this out, Competition Products 1-800-233-0199 sells an Elgin Cam Kit( Elgin makes cams for many companies including ford and chev) $129.95 includes cam, lifters, Z28 / LT1 valve springs,valve locks, umbrella seals and assy lube . A great price for all of that. Check these out.
Part # E903= 223/223, 447/447, 114 Street/strip .4bbl,headers
almost identical to the 327-350 cam
Part# E923= 204/214, 420/443, 112
almost identical to the Edelbrock performer cam
Part# E922= 214/224, 443/465, 112
They have several others to choose from that you may want to look at. With these I listed ,headers,duals ,4bbl. some gear would help, but you shouldn't need much of a converter.You may have a good gear ratio since the car came with a 6 cylinder.
When You purchase the cam kit, make sure you purchase a decent double roller timing set to go with it. A cheepie timing set, just does not cut it. Remember, You are working with a 283, Bigger cam does not always mean better cam.
I would love to have tried a little less valve and a little less cam in dr.bowtie's 57. Im betting his 283 would have been even faster.
Have a Good Day !
