Yeah, maybe I should have picked a different car to play with in this regard, but its what I got, and I still think its the coolest body ever made by GM, so I’ll keep feeding the beast as $$$$ allows.
The rear end from the differential to the outer axles, including suspension is costing me as much as the engine in the Maiden.
How much does a 4 link 9” setup cost?
Toms differentials just got a long awaited backorder of the 31 spline 1350 joint outer axles in today, talk about luck, they’ve been on order for months.
A little back history, Tom the owner died a couple years ago, and its been a bit of a struggle to keep the business running, but Desiree is taking orders and keeping the business alive.
So I got the axle kits and double offset trailing arms ordered and sending them to the guy (Gary) that built my diff. During our conversation today he got into the details of blueprinting the bearing assemblies. These new 31 spline axles (OEM was 17) have a larger bearing surface and the 79 trailing arms have a bigger radius on the legs for attaching the bearing housings. More stronger to rotational forces. They also have 1/2” ARP studs instead of the oem 7/16”. This setup will be much stronger overall than whats under the car now...all rebuilt 1964 trailing arms and bearing support parts.
The double offset trailing arms will allow a wider rim/tire...only to the limits of the frame and rear spring. These arms will move the rear spring inboard a little over an inch on each side. Far enough that the frame itself becomes the interfering factor. I have to get a 2-1/2 inch narrower main leaf to use these trailing arms. A lot of expense for another 2 inches of tire.
I gotta get in line for Gary’s expertise, he’s in high demand.
the present setup shows the rear spring close to the 16x7”, 4” backspacing wheels.
a couple pics of the bearing support/axle assemblies being sent out.
After talking w/ Heath about different heads...Brodix, AFR, Dart, Edelbrock, we thought Brodix made the most sense for me.
After talking with Brodix personnel, the flow numbers favor the 180’s over the 200’s up to about .450 lift. And not a whole bunch more over .500. My lift is net .490/.511 w valve lash factored in.
with my small engine and still wanting streetable performance, the 180’s made a better choice.
Yes, in 1964 90% of Corvettes had a 4spd.
mine did too when I got it, raced a few times and hotrodding on the street had me changing trans or clutches 5-6 times in 3 years with the old 327. But the drivetrain was 20 yrs old and Im not sure how many miles on it.
I thought I was going to be doing a lot of drag racing when I rebuilt the car, had built an L88 for it, and an auto was much easier on drivetrain parts.
I use it to remember things too, back when we had to remember phone numbers and addresses, etc. You can usually pick out an engine or a caliber or something from it to help. And how can you forget there are 454 grams in a pound...(makes it easy to convert to kg, just divide in half and then subtract 10% of the half and you are almost dead on, or add 10% and then double it)
Dis-assembled a caliper...already have a stainless sleeve in there, a nice upgrade! Those are usually 400$ for a set. Genuine Delco-Moraine castings.
I will clean, sandblast, powder coat, and reassembly w new seals.
The pads look pretty new too.
It was actually an L72 427/425. Iron heads.
I bought it in an abandoned 66Chevelle, guy quit making payments on it and the credit union took $50 to get rid of it and close the loan. RIGHT....$50! Not sure what direction the guy was going w the car, but this was 1975. It was rusty, half the interior gone, 3spd manual, non posi rear, not a 12 bolt.
When I opened the hood and saw M/T 427 valvecovers I was pretty geeked. Didn’t really know what it was until I tore it down. Took me another 10 years to build it up again as the pic shows.
Bored .030, Decked, line bored, deburred, 12.5 pistons, Open Chamber big ovals, .570/.600? Solid cam, roller rockers, balanced, etc.
Fired it up in the car, after a couple minutes steam started coming out of the breathers....in the end, the block had a crack in it next to the cam, the length of 3 cylinders. Nobody thought to pressure check it before machine work. Junk block!
Bought a 454 from a burb, and ended up selling it all for 2k plus a complete running 396/325 that I traded for a numbers matching 327/365 short block for my Vette.
