Isky will sell you the cam with the gear drive as a set. I'm guessing this became available in 1963. Oh, you also need to use a reversed distributor drive gear with a reverse helix. Do whatever you want, just throwing out that gears weren't a "70's" thing.
Ok. How about another question.... Do I need to run a 4 blade fan? Or are there other period correct fans that will function better? Posted using the Full Custom H.A.M.B. App!
Based on the choices you have favored so far, I think you would prefer it and a 4 blade shouldn't be hard to find or expensive.
Here's my 1957 283 in my A pickup. It's a front mount only block with a hurst mount and an oil canister. 3731539 heads Howards hydraulic cam similar in specs to the GM 30/30 cam Vintage Fenton 3x2 with oil fill tube and three 97's and vintage frog mouth scoops Vintage Segal progressive linkage Corvette valve covers Vintage Mallory dual point Chevy 4 blade fan Delco generator Rams horn manifolds Here's a couple pics:
I like the 4 lobe Mallory dual points. Point wear is very low; although finding points may be an issue.
I have a 283 in my digger. The heads are from a late 70's 264. The intake is an Off 360 the dual Webers didn't like the intake so I switched back the a 600 Holley. The cam is a 350 horse cam. Car runs mid 7's in the 1/8. I've got a set of the 305 4 barrel heads on the 307 in my 37 Plymouth and they are great but require 93 octane.
Thanks. I don't care for the look of flipped firewalls on 30-31 model A's for engine clearance. When you lose the rounded edge to the firewall at the cowl it just doesn't look like a model A to me anymore. You also lose toe board too. Not a lot but 4" of leg room in an A pickup is a lot. Just under the valve cover clearance area my recess angles forward to the stock toe board location. No modification to my floor.
Depending on the casting #, a 283 block will bore up to 4" with no problems, so your engine at +.040 gives you LOTS of leftover walls for future rebuilds. If you want a streetable 283 that you don't have to rev to the moon to make any power, DO NOT use camel/double hump heads or a "performance" cam (not even the Duntov 097 or the L-79 327 cam). Use the Power Pack heads, and upgrade to 305-sized (1.84) intake valves. Your 283 needs the smaller ports and valves. It also needs less duration than a 327 or a 350. Over-cam it and run heads with too much port, and I guarantee that a stock 2bbl 283 will outperform it in 99% of "real-world" street driving situations. FWIW, if you swap to 305 heads, you ain't building a traditional 283...might as well build a 350.
Weiand and Nicson cast 2x2 SBC manafolds back in the day. Very hard to find. That would cool and unusual.
Here are 2x2's on a small block. Not mine but a very cool set up. I have a '57 power pack motor from a Belair that I am doing the 270 hp deal on it and I am keeping factory (small) heads on it. Won't race it........much.
C Here's mine mocked up... 1960 Corvette 283 being set up to 270 hp specs, 1961 power pack heads, 097 cam with solid lifters and a Man-A-Fre intake. The block is .060 over. My machinist put in slightly larger exhaust valves and some port and polish work on the heads. I have a T-10 4 speed and a 1960 Chevy rear in it too. I have some repro Fenton headers. I am going to use reproduction Corvette "off road" mufflers to get the sound of an old dual quad Vette. The fun part is that a '40 pickup and a '60 Vette weigh almost the same. It should be fun if I ever get back to work on it.
I just bought the last set of Patrick's repo Fenton SBC headers for my 1957 283 project. the rest will be 4 97's on an Offy intake, 10.5ish compression, ported '62 power pack heads, 1.84 intake, stock exhaust & L79 cam from comp cams. Can't wait to get mine together. --Louis
Got a stuck complete 283 with power pack heads from a friend. Pulled the heads......full of rust. I'm not smart enough to know if there salvageable...guessing not.
They should be salvageable. Have them cleaned at a machine shop. As has been said, hard valve seats should be installed so even if the valve seats are very rusty it shouldn't matter.
Resurrecting this thread for a quick question..... Anybody know what the compression ratio will be on a 283 using 462 casting/1.94 heads and stock pistons? The pistons are typical relieved flattops, probably TRW and the motor is 0.30 over, not that it matters. I believe they were 8.5 from the factory.
Assuming 64cc chambers & .041 piston/head clearance, about 8.7 to1 Sent from my iPhone using The H.A.M.B. mobile app
