Hi Gary,
Do you remember the contact person at CSS who is familiar with your order? I would like to purchase a set based on the specifications you sent them.
Regards, Terry

Impressive. I learned  something here then. I have been around racing, but not nearly as long as many of you. I had no idea this was used as an alternative or in even purposeful in racing. Thanks for the education.

. Can I use oval port intakes over rectangle port heads? .

This is generally the preferred method when trying to gain velocity in the intake track, at least it was 20 years ago.  Buddy of mine for years ran his street/strip 68 chevelle this way.  427 with square ports, then ran a Victor Jr. oval port intake on top.  Tony Bischoff (multiple EMC winner) built the engine and it made fantastic power for a small engine.  The all steel chevelle ran 10.60's at 125+ with a  small tire and stock suspension (no back half) and he drove it on the street everywhere.

Looks like I lost the Ebay bid anyway. Might look for an oval port next time. I have never ran a big block tri power but I think it would have that day 2 cool factor. Keeping all the real stuff on the shelf if I do it.

Not the most efficient as you mentioned but with the right set of gaskets it seems like it would work. If you swapped one way and the water jacket and ports lined up pretty close, it would seem you could do the same in reverse. Have I ever done it? "No."  That is out of my comfort zone. I have Mickey Moused some things on cars over the years to "make it work", but even if the car ran just a little inefficient, it would just rub me the wrong way.

They are installed, but parts of the car (fenders, hood, core support, radiator, etc) are not installed as yet, so ride height not finalized...  Since I had them match all the physical specifications of the  factory EY spring I sent them, I think I will be happy with them... certainly more happy than buying OTS springs which perhaps match the ride height (maybe), but none of the other physical specifications...

PS.  I do have the physical characteristics listed herein (0.610 wire diameter, 8.125 Total coils, Inside Diameter 3.675,
Free, or static, Length 15.00 +/-, Load Rate 370#/in).  .. and here is a photo of the one original EY spring, along with the pair from CSS...  (one of my original EY springs had a broken coil necessitating the new ones).

Hi Gary,
Do you have them installed on your car and are you happy with the ride height?

Yes, I am familiar with it and would love to have one if anyone has one they will part with.

Thanks,
Rex

I had Coil Spring Specialties (Kansas) build me two EY springs to match my originals in static height, spring rate, coil dia, and number of coils...  as recommended to me by Steve Shauger (PaceMe)...
