I pulled the trigger on a 427 sbc to match Pauldanas build. The major differences will be , intake manifold and i use the EZ EFI 650 hp set up.
Another difference is I have an automatic car .. Currently a stoutly built 700R4 . This can and may have to change.. Any suggestions ?
Here is where I need some help , front end I am going to redo it 100% , clean paint/replace and go to a borgeson unit for steering.
What is best kit for re-bushing of the front and is a coil over system available that is reliable and good ?
Rear suspension > I have a 1980 .. The rear has been rebuilt with aluminum caps replaced (Billet) and gears are 3.92.
Anyone with 600 plus hp and 580 plus torque out here have any solid ideas for a rear set up ? I know i am going to need strength but I also am hoping not have to go to a drag race set up .I would be way happier with a pro touring type of system .. Any ideas ?
And lastly tires and rims .. good grip tires and rims that will work with a made over rear suspension ..EVEN rim style ideas are helpful

The earlier Iron pumpkin fitted with a 12 bolt will fit your car with minor modifications. You can use the Tom's inner and outer 30/31 splined axles 1480 flanged halfshafts.
Beejay put the batwing in his 79 and fitted the iron pumpkin. Batwing is already in your car. See no reason why you can't adapt the Iron Diff. You could go coilover as well. https://www.corvetteforum.com/forums...g-install.html
Thanks 63Mako ! I wonder how he fit that bat wing to that iron diff ... Hmmmm got to read a bit !!
Your batwing is already mounted and the trailing arms are the same and also mounted. Everything for the 12 bolt and the 30/31 splined inner/outer axles, 1480 halfshafts are available @ tomsdifferentials.com. Not cheap! Should get the majority of the info you need to figure out the conversion from Beejays detailed post and it shouldn't be too bad to do. Start a thread!

Toms site is very difficult to use . Ill search around .. I looked at BJ's thread but i can not tell if he is using a c- bat wing or c-3 . I think it is the c-4 because it has a drain plug in it /
Also i do need cash and carry I am never going to fab something myself

I think the iron differential bolts directly to the batwing replacing the rear cover with no fabrication needed. Send Bee Jay a PM. Here is a picture of the 63- 79 gasket and 80-82 gasket. Looks like the 8 perimeter bolts are in the same spot. 84 is a totally different bolt layout. Bee Jay has a 80-82 batwing.

Peoples opinion on this. I have Billet caps holding the carrier together and a eaton posi .. I am also an automatic car .If I use or curently have all the larget big block shafts and u - joints do you think it will be tough enough ...
If you want the strongest advertised 700r4 look up PATC.I warn you now however it won't be cheap.They even offer a closer ratio gear set if you are interested.

600+ is a lot to ask of a basically stock posi. A guy just posted a picture of his twisted off inner axle behind a ZZ4 auto. The caps aren't the main problem. The entire unit just isn't designed for that much power. That said I think Motorhead has a stock 80-82 rear in his behind a 600 HP W/ TKO600. Don't know for how long.

I have an eaton posi in there as well.. I think what I am going to do is confirm the U joint size , if it is already 1350 I will just detail the suspension add drive shaft loops and see how it goes ..
If it is the 1330 joints ill upgrade to the 1350 parts
I admit I don't own a bat wing setup or a 80-82 rear end. Does a c-4 bat wing actually hold the rear end more rigidly than an improved C-3 cross member or is it just all bling?
I've said it over and over again that limiting rear wheel vertical travel seems to make our rear end and parts last. I'm also a believer when things break then install upgraded parts and I'm big on safety items.
As far as front coil overs. You can buy all new tube a-arms and have a true coil over or rebuild your old and have a QA-1 semi coil over setup.

Thanks ,, the front end looks like it may cost 2k plus to go tubular and as I do not road race I am thinking the moog springs ( supposed to lower car 1 inch) and a full replacement of steering parts including the gear box
I just cant justify replacing the a arms at the costs these guys want

I just like the adjustability of my QA-1 and the springs are cheap and in 50# increments from Speed Direct

The "magic" Dana 44 is still alive and well.
IIRC Monty made his only 11sec 150+mph pass on a stock '80 Dana 44 aluminum rear end behind his 1200HP 427ci turbo small block. They can take a lot more than most think
