Thread: Stroked 283??

Tweet

Anyone ever heard of boring and stroking a 283 block out to a 327? Bore the 3.875" cyl to 4" and use a 327 crank (turn the journals down).

Someone brought this up on a Studebaker forum and I was curious if it is possible.

Is there enough casting in the cylinders to take off .125"?

If you want to build a stroker engine just build a 383.This would be very expensive and you are still down in size.

Lots of 283's got bored to 4", makes a 301. The small journal 327 crank will fit the main bores as is.
That said, there's not much point in spending the time and money when there are lots of 327's and 350's around.

Erik, I agree. I'm not wanting to build one (currently building a 383), just wondering if it was possible.

I think some of the Studebaker guys might think that using a 283 to build a 327 has a connection to original Stude equipment since the 283 was used for a couple of the later years, where if they put a 350 or straight factory 327 they might be violating the Keep It Stock Stupid oath many have taken. (just my opinion, no offence intended (chevy rules!, offence deliberate and intended!)).

Risking the wrath of the purists and my elderly father, the 383 is going in the '65 Commander this spring.

Yeah, I've seen 283's bored to 4" forever and ever and I've also seen 'em overheating like hell from the thin walls. If a guy bored the 283 block 0.030" just to clean it up and installed a 400 crank, he'd have a 360. If I did it, I'd use 400 rods to keep the clearance issues to a minimum.

just cause you put a small journal 327 crank in a 283 doesnt mean its a 327. that makes 302 if bored.125 BTW tech ive got a 160 thermosat and it dont go over 165 the late blocks 64 and up are good for boring out because of higher nickel content the early blocks 57-63 and some early 64's arent so good lower nickel and they would get hot faster. and if you really want to go crazy make a 402. use a 1 inch stroker crank grind the pan rails down for clearance and with a bore job you've got 402 that combo is courtesy of big yohns racing in there olden days with the "shubert & herbert" blown sbc rail. anymore questions?

Sure I have one.So what you are saying is all I really need is a 40+ year old 283 block to build a 402.Then I need to grind the pan rails out.Then I need to find a crank with a 3.75 stroke.Do I need to buy a crank with the 2.3 main size or the 2.45 main size?How about the rod bearing size do I order a crank with 2.0 rod bearing size or do I order the crank with a 2.10?Let's not forget you will have to grind the rod bolts or get a small base circle cam.Wow!!You left out some important information.Wait,I know what some of you are thinking.You would have to run a 2.3 main size.Have you tried to find a small main journal after market crank?Oh, here is another one.What about 4- bolt caps?

Scooter, actually a 283 bored to 4 inches and using a stock 283 3 inch stroke is a 302. (in the 50's and 60's we called a 301, don't know exactly why) A 283 bore with a 327 3.25 inch stroke is a 307 which Chevy produced from 67 to sometime in the mid 70'2. Had one in a 72 Chevelle. Decent torque for a family car and decent gas mileage to boot.

just wanted to see if you guys were paying attention

You have to get up very earily in the morning to fool some of us.

This all is sounding more and more like a F*rd solution

(I know, I'm bored and am trying to start something)

Hey watch your mouth.Shame on you. On Christmas eve.I wish you would not use the F- word like that

Peace on earth, good will to all American owned car manufacturers!

Speaking of F*rd's, check it out. Last year my dad's place was wiped out by hurricane Charlie. Look which building survived, the Model T barn. The garage around the Buick exploded, but the car was soo heavy it just sat there. (Just property damage, no one hurt)

What year is that Buick?It has (Pro-Street) written all over it.I can just see the wheeltubs and 4-link if I owned it L.O.L. BUT WHY RUIN A NICE CAR?

If I remember right it's a '42, and I imagine it will remain purely stock and factory correct until they bury him in it.
