Valve Springs research

[CZLN6]

Howdy:

I hope some of you have seen and read the article in this months issue of Hot Rod. It's the issue with the rat rod roadster pickup on the cover. Incidently with a Ford 300 six with three Falcon glass bowled Holley one barrels on the cover. Will wonders ever cease! Anyway, they ran an excellant article on valve springs, in general. It is a very good read.

Along the same line I recently received a tip that Chrysler 3.3 V6 engines have a beehive valve spring and retainer that is compatible with our 5/16" valve stems. I haven't had the time or the opportunity to check it out, so Please!!! Anyone with Mopar 3.3 V6 parts laying around, check it out and share your findings. Details like free length, diameter at the base and the top, and, If possible spring rates at open height of 1.22" and closed height of 1.59". And any other details of interest.

Thanks, in advance.

Adios, David

Here's an update on the 3.3 Mopar V6 conical valve springs. I still have to check out the pressure at heights.

A new spring/retainer combo that may be an option has recently come to light. It is a conical spring and one piece retainer from a Mopar 3.3 V6 engine, from 1996 -99. Comparing the stock 200 spring/retainer to a Mopar 3.3 V6 spring and retainer is as follows;

stock 200 Mopar 3.3
Springs
Free height- 2.06” 1.97”
OD @ base- 1.36” 1.39”
Wire dia. .162” .19”
Weight 66 grams 70 grams

Retainers
Weight 30 grams 12 grams
Height .45” .39”

Spring/retainer

I've got some stock beehive springs from 4.0L amc sixes and some from some 5.7L Hemis they are both 8MM stems.

I'll measure these and report back. The 4.0L should be very easy to find if they are the same.
