I am very interested in learning all you can tell me and the community about your engine swap to the 2019 LS2 L96 Silverado engine and 6L90 trans you installed in your 63

Any details you could provide about HP cubic inches and costs involved Etc especially since you did drive the stock 390 in the car as well for comparison ( sure there is little ) 

There have been others who have considered  doing a swap of this kind 

Being able to connect the stock creature comforts of the 63 would be another interest of mine

The stock engines for these cars will be more  and more difficult to be using as time marches on 

Thanks in advance for any info you can offer 

Stay Safe

Hi all, 

Sorry I missed this question yesterday.  Some great questions and I am happy to share all the details in excruciating detail, if you'd all like.  The original 390 that was in my 63 was not untouched prior to me acquiring it.  A rebuild had been done about 8-10 years before and at some point the original 4-speed automatic transmission was swapped out for a 64's 3-speed auto.  I say all this because I would have kept closer to original had the work of mismatching the powerplant and drive train not already started.  I have a lot of receipts and inventory of all that was involved in getting to a finished product.  The engine and transmission were easy to source - required fabricating mounts, enlarging the transmission tunnel and ordering a newly machined custom driveshaft.  Plus 3-4 dozen assorted parts from different performance / custom manufacturers.  I'll detail this with some pictures tonight. It's worth it for me to write out the whole story and I hope you'll find it worthwhile to read.


That is wonderful and looking very much forward to the details 

Thanks and Stay Safe

1964 power steering sector rebuild

Posted by CHRIS CARLSON on March 20, 2023 at 11:32pm 3 Comments

 I'm having my steering sector rebuilt, and considering changing it from 20-1 ratio 4.2 turns lock to lock to 3.5 turns lock to lock @ 16-1 ratio, If i change from a 3 1/4" box to a 3" box i could have a 14-1 Ratio steering response would be faster, shorter distance to turn the wheel to get a response,   has anyone done this? and how do you like it? thank you

Need help with a hood latch

Posted by Curtis Dover on January 2, 2023 at 5:23pm 0 Comments

Hey guys, I need some help.  Could someone send me some pictures on how the first hood release lever on a factory 1964 Cadillac is set up, where it comes though the grille. Not the secondary one. I need to know where the thumb or finger position is located through the grille. Is it above or below the center grille molding piece? Mine seems to be positioned behind the center molding piece and will not adjust above or below the molding. I have a wire tied to it to release it…
