Hey everyone, I apologize if this has been beaten to death but I recently acquired a 63 Nova 283 4 spd through some circumstances. Id like to do a 327 for it in period correct-ish form. After some searching an early 327 block was out of the question price wise and I came into a large journal block with standard bores and a (based on my research) forged 1130 crank. My question is can the rod journals on that crank be turned down enough to give me some h-beam rod options? My goal is to build a mill that would’ve been respectable for its time. Not interested in 1.3hp/ci stuff, I built enough of that on Harleys. But something in the 350-375hp area that will probably not see much action north of 6500 that is mated to a Muncie with 2.52 first. Id like to stick with some original camel humps but those are for another thread.
how about some pictures of the crankshaft? just curious what it really is...that number pops up as a 307 crank, they were cast. and the block numbers? just curious what you have. and why would you want to turn the crank down for strange rods? Factory large journal rods will work ok for what you're doing.
Any 5.7" rod from a 350 chevy [2.1" journal] would fit that engine. Why turn it down when 2.0 journal rods are more difficult to find than 2.1 rods https://www.summitracing.com/int/parts/sca-6570021/overview/make/chevrolet
Ya know what, just realized I was thinking of the wrong journal size. Thansk guys. Need. More. Sleep.
You can also turn down the mains on a late crank to use in an early block [and keep the 2.1 Rods] Or bolt a set of late model main caps onto the early block, and get the saddles Tunnel bored [line bored] for the large journal crank
LOT'S of racers used the large journal mains with the small journal rod throws. No problem for machinists to do that. That's basically what you're asking. I have a set of large journal rods for shipping only if you'd care to go that route. Why a nodular iron 307 crank? Lots of large journal, forged, 327 cranks out there; I have one of those also I'd make a deal on. I am Butch/56sedsandelivery.
My research has shown the 3951130 crank to be a forged large journal 327. Is there other literature that indicates differently?
The circumstances are that the car was supposed to go to my best friend when he turned 30 years old but he was killed in a motorcycle accident 6 years ago. The car was owned by his dad for 33 years and recently said he was going to sell it. I didnt want it to go to a stranger.
Best pic i can do of the crank. I do not have the actual crank in my possession yet https://m.ebay.com/itm/1968-1969-Ch...-Crankshaft-Fresh-Grind-020-020-/391831249933
Sorry to hear those are the circumstances. Glad you were able and willing to keep it in family the best you could. ...and it is pretty effing sweet.
A 3951130 crank and an 1130 crank are not the same. 3951130 is forged large journal. 1130 is cast large journal. Both are listed at http://www.nastyz28.com/sbcmenu.php
Welcome to the HAMB, neat Nova, you don't see many with those teardrop hood scoops. I see you just joined so you probably haven't seen the Chevy II thread yet, we would love to see your Nova here also. https://www.jalopyjournal.com/forum/threads/chevy-iis.397699/ HAMB 327 threads here. https://www.jalopyjournal.com/forum/threads/the-hamb-327-thread-index.1090356/#post-12359849
[ Yep, several sources say the same thing. Sounds spendy for the Ebay one until you start figuring out what the 327 part peddlers at swap meets want for one and the current cost of having it turned. I love the looks of that car and wouldn't change anything on outward appearance.
how about just using a 350 crank.............cheapest, easiest way to get the "look" and those hp numbers.
Ahh i didnt even notice there was an “1130” crank I just shortened the casting number to the last 4 digits, just my luck I was able to cause more confusion than clear up. I dont mind spending money (wife can verify this) so I can have piece of mind on things holding together even though I dont plan to twist it up often. Going for early 60’s performance so a 327 it will be. Thank you for the compliments on the car. I know my bro would approve of my plans.
So I got the crank yesterday but have some questions. It was sold as being forged but not sure if a forged unit would have the full 3951130 number on it as this one only has the “1130”. It has the wide parting line and other forged characteristics though. Thoughts?
Not sure if GM cross drilled the large journal 327 forged steel cranks..... Might be something to look into......
I just found your old Post. I have the same crank 1130 is cast into the crank not the full # so it can be confusing but the thick casting line tells what it is. Here's picks of my 1130 Forged steel crank. Hope you get your 327 up an running. I owed a early Chevy II back when I was younger it had a 400 with a 4 speed muncie and 4:11 posi I traded my 56 Chevy 210 with a 454 in it for the 64 Chevy II I'd like to have them both back but long gone now. I crashed my Honda into the side of a cube van back in 1985, I was in the NCU for several weeks so I traded my Chevy II for a nice stock 84 GMC pickup I was afraid of speed for a few years after crashing my Honda. I later put together my 79 Z/28 and that was my last Hot Rod back in around 1998 until I bought my 63 C10 pick-up in 2016 now doing a 327 I've posted about it and the not so good speed shop doing me wrong but that's in the past now. But I can't find a picture of my white Chevy II maybe I'll find it someday?? But here's pics of the 1130 crank an my 56 Chevy 210 and my 79 Z/28. Good old memories LOL... And my 63 C10 pick-up, needing new Windshield in Pic with my youngest Granddaughter & me. Have fun with that sweet "Loose Deuce"... 1Nimrod
