Little mouse that Roared

[kwplot34]

I have a 283ci in the 67 chevy truck i purchased from Darrow. So i have been thinking, why take the motor out and shove it in the corner with the other motors, let's build a high revving, HP making motor out of it.

I can't find to much in my books on building this motor up (they mainly talk about 350's and up) but i am sure it can be bored and stroked.
This will make a good winter project,so lets here what you have,or some building info for this motor.

1. new rotating assy(crank,rods,pistons)
2. solid cam or roller cam?
3.Heads,i am sure these old heads probably don't breath well
4. stroke it???
5.can it be built into a 302?

Stroke is where the torque is, and for a truck, what's what you need for driveability, unless you got a 5+ speed.....

I had one in my '60 vette with a WCFB on it, iron throttle plate and all.....

:surrender:

why take the motor out and shove it in the corner with the other motors,

what other motors do you have ?

A 350 and a 454 and a 327.

 

[MYBAD79]

The 454 would be my choice for a truck. How much money do you want to spend ?
A budget stroker assembly would get you 496 cubes...

 

[big2bird]

What will the truck be USED for?:wink:

 

[Twin_Turbo]

To build a 302 you need a 3" stroke and a 4" bore, your puny little 283 has a 3.87 bore

Why waste money on it unless it has some collector value? Dump that 454 in there and if you have no use for it crate it up, I'll arrange for it to be picked up

If you want to stick w/ a smallblock and have a nice revving engine, use the 327.

Me and Budgets don't work well together,I usually blow the budget half way through the build :suicide:

To answer Birds question,the truck will just be a 2nd vehicle another toy :wink:

The 283,i have no idea if it has any collector value,maybe to the right person it does,it is the original motor for this truck,but when i get done with this truck it will be far from original.
The 327 i have had since 1984,rebuilt it and ran it a 1970 truck for several years, did a 454 build already,several 350's,but i have not built a 283 yet. So just looking for something different .

 

[Twin_Turbo]

it may sound cute, that little 283 but you will regret it the moment you put your foot in it and all it does is putt...putt...putt

 

[big2bird]

The I agree with Marck. I think a 327 with a mild cam , with nice headers and manifold /carb, and very little bling would look nice in there, and serve it's purpose.
It will be easier to find parts for it too.

A Z-28 style 302 is a 327 block with 283 crank. Oversquare, high revving. Probably not really what you want for a truck.
A 301 is a 283 block with a 327 crank. A stroker 283. You don't hear about them much anymore, but they were pretty trick "back in the day". The 383 of the early '60s. It would probably work better in a truck--more torque.
I like the idea of building a 283 (stock cid or otherwise) & make it run good. My '56 Chevy two-door sedan was surprisingly quick with a 283 & M-21 in it.
That truck is pretty light, wouldn't it be fun to build a hot little small block that is NOT a 350?

For my education: Aren't all 283's small journal cranks and only some 327's small journal cranks? That would mean to make a 302 you would have to get an early 327, correct?

Those 60's Chevy trucks are pretty light. I think a small displacement, high revving motor in a PT style one might be a blast to drive.

I don't really know, but that sounds right. The only 302s I ever met were actual Camaro Z-28s, factory built to meet the engine displacement rules for Pony Car racing in the '60s.
I did however know a couple guys who built 301s for their '55 & '57 Chevys.

Heck Kevin, if you want to blow some minds, build a hotrod straight 6. They can run real good too and it really twists peoples heads......

 

[BRUTAL64]

Back in the early 60's 292 Chevys (.060 over 283s- there were some 301s -58 to early 62 283 blocks-running around too) used to be the big thing. Some were getting as much as 500hp. I talked to guys that used to rev them past 7500 rpm.

I thought a 283 w/327 crank was a 307. Isn't the 301 a 283 punched out 1/8 inch?

I found this while looking for some builds,looks interesting and easy enough to build.

It's tough to find affordable pistons that will yield 11.0:1 in a 292 with decent heads. Here's what I came up with just foolin' around on the DynoSim.
283 bored 0.060"
Keith Black hypers, KB166-060
L31 Vortec heads, cut 0.040" for 58cc chambers. Stock 1.94/1.50 valves, springs and retainers matched to lift. Makes static compression ratio of 10.5:1. Heads are bone-stock except for springs and retainers and the 0.040" cut. You can rescue 'em out of a boneyard. Casting number 12558062 in a '96-'98 Chevy truck with 5700 Vortec motor. Look for a saw-tooth design on the front of the heads. Get the rail rockers and center bolt valve covers at the same time you're gettin' the heads.
CompCams solid flat tappet cam. 12-221-5, grind 280B-8, 280/285, 242/250, 507/532, 108.
Large tube stepped race headers
Edelbrock RPM Vortec intake w/750 carb
RPM HP TQ
3000 201 252
3500 253 380
4000 312 410
4500 372 434
5000 424 446
5500 457 436
6000 489 428
6500 502 406
7000 507 380
7500 505 354
8000 495 325
136 mph top speed @8000 w/4.88 gear, 28" tire. Use 3000+ stall converter with auto. Would be way more fun with a 4-spd/5-spd. I realize the original poster asked for a way to enlarge his 283 to pull a truck. This is not the motor to do that. This is a play-toy built the way Scooter might do it. I just wanted to dyno it and see what it looked like. Who says you can't make 500 hp out of a budget 283??? A guy might have to massage the domes a little to fit the chambers, but you'd still make 500 hp even if you dropped the SCR a couple of tenths. Disable the centrifugal and vacuum advance and lock it up at 34-36 degrees. Install a switch through a relay to disable the ignition while cranking, then flip the switch to ignition-on while the motor's spinnin'.

A BUZZ'N 1/2 DOZEN i have seen one of them at the drag races before,a long time ago.

I know the 283 is not a monster motor,just looking for something different,stroker 350,and 400's are every where along with big blocks.

Actually a 301 is 283 block punched to 4 inch bore. A 307 is a 283 bore with a 327 crank.:noworry:
