4.3(262 cdi) v8 value

Postby jim327monza » Sat Sep 30, 2017 11:49 am

A locked up water pump on my 4.3 has accelerated the instillation of the 327 . The 4.3 has 120,000 miles on and still runs well. Other than the exhaust manifolds and the Rochester 2 barrel, is the engine worth any thing as a 262 or as a running sbc v8 or am I just looking at scrap value.
Thanks Jim H.

In all honesty I doubt a stock 262 with a 120,000 mikes has much value. Most people aren't going to rebuild a 262 and being the smallest of any smallblock there is not much demand.

Many years ago people told me you couldn't do anything with a 262.5. NEVER TELL ME THAT! .030 overbore .010/.010. Clevite 77 everywhere. Crane 350/327 cam. Holley Z-series manifold and a vac-sec 600. Hooker 2135s and true duals with three-chamber Flowmasters. TRW double roller chain. Melling M55HV oil pump. Fed by a Holley 40gph pump in the back after the stock in-tank pump puked.
Carb tuning was a "challenge" but that little puppy ran like a raped ape! For over 100,000 miles after the rebuild. And it's a 4-speed car.
350 in it now but the 262.5 is in my garage. Maybe a ring/hone and new umbrella seals. I'll freshen it up one of these years and find something to drop it in.

Of all the "baby" (SBC's 262, 265 and 267), the 262 is by far my favorite. I had a few V8 Monzas as daily drivers, and one Vega with a 262 swap; always enjoyed the quick to rev 262 (as compared to the lazy 305). Not a ton of power, but alway fun to drive. The one in the Vega had a 4-bbl intake and a Quadrajet, along with custom bent 2.5" single exhaust. Easier on fuel than the 4-cyl it replaced, but I'm sure by today's standards it would feel unbearably slow.
Worth anything? Maybe to someone trying to restore an early Spyder.

Thanks for the reply's. Art I could a dozen Krispy Kreme donuts and a high end Starbucks if i dont count the cost of gas to go to the scrap yard!
as for building the 262, the thought is intriguing but I have more projects than time and money. If someone is interested in the block I would probably let them have it. Right now I need to move forward with the 327 installation and get om the road.
Thanks Jim H

A friend of mine told me the crank has value as it can be used in a 350 block to make a high RPM engine. Don't know for sure, haven't researched it.

It isn't supposed to be a very tough crank, but I never tore mine down so that is second hand, so I ran the calc. and it spit out 316.3 cubes [@+ 0.030" over],that is lots of bore for that many cubes. They were supposed to have the same "Main Bore" so it should be possible. Probably better would be 4" [bore] heads on a 0.030" over "400" block with the "Thick Bearings" and you end up at 340.7 c.i. There is an online write up about the two 350's GM did and could have built, the one we all know and LOVE and the other was built with a "400" block with the 327 crank, the latter was up about 30(?) HP [and torque was up too] as I remember to the one they did build.* [Same everything just the block and crank were swapped out, reasoning given, valves were way less shrouded, this was with a conservative HiPo street build. Anyway back on to the secondary topic, that would be a "Screamer" in a nice light platform such as ours! I also had a 4.3L in my '76 and like Spencer and others have said, while not really fast I LOVED driving that car, enough to have fought hard to have at least one for 35 consecutive years starting almost straight out of high school!

Harry brings up the subject of "de-stroking" a 350 with the 262 crank. In theory, a shorter stroke engine will rev higher,but the 262 crank is only cast, so it wouldn't have anywhere near the capability of a forged one. The only place you see destroked engines these days is in NHRA Competition Eliminator where classification is done by LB/CID. So a short stroke engine can make nearly the same HP as a long stroke one, just at a higher RPM.
With the widespread availability of decent quality aftermarket crankshafts in any stroke you wish, most racers opt to get their cubes from longer stroke engines, like the Chevy 383(a .030 over 350 with a 3.75" stroke, 400 size) crank. Being able to make the power at a lower RPM puts a lot less stress on internal engine components; valve springs, lifters, etc. last a lot longer.
