283 Stroker??

Ok, new here, hope this post isnt too dumb, here goes-

I realize the cheapest way to make power is to increase cubes. Ive seen all sorts of stroker variations on the 350 that are very effective and effecient.

Im in the process of buying a 63 Impala SS, with a 283. Being such a heavy car, im thinking a torque increase would be real nice. Figure one easy way to do that is to stroke it *if possible*

What i currently have to work with is on the current engine is the following-

Edelbrock Performer intake
Edelbrock 600 carb.
K&N 14"
Hedman headers/2.25" exhaust system
MSD ignition system

At a minimum i am going to add the following work/parts-

bore .030 (or more if needed)
Comp Cams 270 (or maybe 280)
Forged pistons (want to have final net compression between 9.5:1-10:1+/-)
New valves (1.94)

Will do all proper tweaking/tuning on heads/intake etc...

My question - is it possible to install a 3.48 stroke (350) crank into a 283 block? If so, what are any potential issues that will arise?

Thanks in advance.

"My question - is it possible to install a 3.48 stroke (350) crank into a 283 block?"

Short answer, no. Main journal diameter on the 283 crank is 2.300", on the 350 it's 2.450. Counterweights are much larger on the 350 crank and there will not be enough meat in the webs to clearance the block. With any bore smaller than 4", custom pistons would be required (read...high-buck). Rod journals are larger on the 350 crank, but you could skirt this issue by using 350 rods.

Even if these hurdles were not in place, you'd have breathing issues using the small-port 283 heads with much larger displacement.

This question in one form or another comes up often on this forum and I'll give you my standard answer. Yank the 283, wrap it in plastic and store it in the corner of the garage. Locate a good-running used 350 (do a compression test on it before laying down your green) and start with a valid player. Want more power? Bolt in a Scat or modified Chevy 400 crank.

There are others on this forum, like Scooter :), who will disagree with me, but that's the way I see it from a common-sense point of view.

Thanks Tech. i figured it would be a "no go" or it would be common practice already.

I have been thinking about yanking the 283 and the 3 sp. and installing a strong 350, 383 or 400sb, along with a 4 speed Muncie.

Another question i have, unrelated to the original is final gear ratio on the 3 speed trans. the same as a 4 speed? (just trying to get a higher final ratio to run lower rpm at highway speeds etc.).

I dont want to go through the cost/trouble of putting a 4sp. in if the final drive ratio is the same as the 3sp.

If you're talking stick shift, yeah they're both 1.00 final drive in the earlier boxes. If you're talking auto, the late model 700R4 four speed had an overdrive 4th gear.

stick shift... so im gonna stick with the 3sp. thanks... now to find a good clean 350/400 locally:rolleyes:

Lamey, for the 400, start checkin' full-size Impalas, station wagons and pickups beginning in 1972. There should be a ton of 'em around Biloxi that those good ol' boys have parked in the weeds. :LOL:

HELLOOOOOOOOOOOOO....... if you still want to build your 283 and do it the right way get ahold of me through my email you wont be sorry................scooter p.s dont worry about tech he is dillusional:whacked: :LOL: :LOL: ....scooter p.s 283's is not a wasted effort. i mean ive got the proof:3dSMILE: also if not ill take ur 283 hehehe..........

WHAT????....ME?????.....dillusional???? :whacked: :LOL:

Hey Pro60Chevy, can you post that picture of the fish with the hook in its mouth???:LOL::LOL::LOL::LOL::LOL::LOL:

So . . . . I want in on this. Can I destroke my 350 to 283? :LOL:

All im wanting is a good strong daily driver,time and money are an issue so for now im gonna stick with the 283. If it doesnt work out (lack of power) i will find a 350/383/400 to build.

Just need to get it on the road for this summer.

Fellas, why does this post draw so much sarcasm? I just dont get it. I know when some one asks me about Bladesmithing, Gunsmithing or anything else im knowledgable in,, the last thing I do is give the person posing the question comic relief.

We're just pickin' on Scooter because we love him and he's easy.

oh i see... my humor is just low tonight, guess its the rain:rolleyes:

:3dSMILE: someone on my side finally!:3dSMILE:

"just give him time" ........... :rolleyes:









:LOL:
TL

I think gasser wants a pair of 283's for earings...

:whacked: :whacked:

Lets go thru several questions here.

Speed-o-motive offers a 383 stroker kit for a small journal 327,
so They may offer something simular for the 283. the journal sizes are the same size. You could call them and ask. You would need to do some block work to stroke the 283 and You would need to use a little better head than the 283 heads,although the 283 -4bbl. and the 327-250hp shared the same head in 1963.

The cheapest way to go here is to purchase a good used 350.get the complete motor. If it needs to be rebuilt you can buy a complete kit for a 350, including cast pistons for less than $200.
I have build several 355s with a performance cam for less than a grand.They run good and would be fun in your 63.

283s are no slouch either.You are missing a lot of cubes there but you can still get around 275 to 300 hp for the street.

I think 1963 may have been the first year that the 3 speed transmission had a syncronized low gear.It was a vast improvment. A 3 speed and a 4 speed both have 1 to 1 high gear

But, Buy the 4 speed anyway, It will make the car! You will enjoy your 63---- TEN TIMES MORE :LOL: :LOL:

Here we go......

400s were built from 1970 thru 1980. 70 and 71 were 4 bolt blocks with 3 freeze plugs on the side of the block.72 on were 2 bolt main blocks and most only had 2 freeze plugs per side. The 2 bolt is just as strong as the 4 bolt and many feel the 2 bolt may be stronger. I think this applies only in the 400.

Because all of us believe bigger is better,even some of us old dogs seem to have fogotten how good a 283 could be made to run. Way back when, I shocked quite a few of the Big Boys with a little 283 in my 56 Chevy. :LOL:

I think he's hooked really good, go ahead an pull him in !!!!! Oh, by the way. I could maybe let 2 or 3 more investors in on this real estate deal I got going!!!!!!

:confused:

Dave, Are You directing that at me??? If so ,thats O.K. Hope You have have a wonderful Sunday with your friends and family.

Oh, If you can guarantee the same results I got on my last real estate deal, Please, Please ,tell me more!

I made 3 purchases at one time.I have recently had an offer on one of them for 6.52 times what I paid for all 3. I think they will pay more. I guess I could have asked if he had a nice hot rod to use as a partial payment.

Unlike old cars, I dont know of any reproduction companies on land. The valve will only go up.

I am normally in Church at this time on Sunday. Could not go because of illness in the family. Think I needed it bad. Maybe I wouldn't be quite as ugly.

Have a Blessed day! Gene:)

Gene, let me bring you up to speed. Scooter is the 283 king on here and I pick on him and he picks on me for downplaying the little 283 motor. He was trying to convince lamey to do the 283 and said if lamey would contact him via email, he'd detail the build. Lamey sent Scooter a PM and I asked pro60chevy to post the hooked fish because Scooter was settin' the hook in lamey. It's all in good fun, just trying to lend a little humor to the board.

Nope Horse, just directing that comment at life in general !!! Scooter be the czar of 283's, the king of the mini-mouse, the only one here who looks at a 10 grand tach and wants to know where the ones with the big numbers are!!!!! Scooter makes the mouse scoot!!! (And I never pass up a chance to mess with him!!!!!!!)

On the real estate deal, just send cash and I'll fill ya in on the details later. Trust me, it's a slam dunk, can't lose, money tree, cash generating double throw down killer deal!!!!!

Thanks Fella's !:)

Dave, That sounds like a Great Deal!

Why am I hesitating? :confused:

Sometimes you just need to grab that hook! :LOL:

Go for it Gene, it can't cost THAT much to drain the water off it :LOL:

well someone has to keep you 350 guys inline:LOL:

Hey do this if you want to run a 283....

Use the 283 as the base and throw in a set of vortec heads? these flow really well on small motors....or? get a set of torquer 305 58cc castings....bothe are relatively inexpensive and when combined with a high winding small motor can produce upwards of 350 hp with a 270 series cam....

I have 10 or so 283's lying around and will take any than anyone want to sell for a reasonable price.....

With either head choice I have suggested and a "good" cam 350hp is easily obtainable in the 283, 307, 327 and you can easily knock down 22-26mpg....something that takes work to get that kind of mpg out of a 350....Think about it....

Hey Tech, it's not a lot of water!!!!! And besides, I'm holding first option on a bridge to go with it!!!!! I tell ya, can't miss on this one.

im in a better mood today and still dont get all the smarta@@ comments.. maybe i need therapy:whacked:

Its quite obvios to anyone that can think, cubes are the easy power, that is not in question here. I just want to work with what i have (the 283), for this summer at least. For my "winter" project i will probably rebuild a strong 350/383 and 4 speed. I will then mothball the 283/3sp in case i sell the car or want it restored to exact original condition etc.... Hell who knows it may wind up with a 502.

This can sure get confusing and addicting.... fast.

any how, for those that have given good advice on the pros and cons of the specific question i originally posted, Thank You.
