hi black sheep, the inner dia is the same on the stock springs and the 340 springs (mopar p4120249 red with a damper)i know you have elgin, but they are the same as the 340 springs. to sit properly on the 8 degree spring retainers. . the wire dia is thicker on the 340 springs with less coils . to keep the inner dia the same to fit the retainer ,the spring od goes from 1.39 stock to 1.50 od ,so the spring overhangs the retainer all around , but is centered inside on the retainer. ron |

Don't worry about a little spring exposure around the retainer, they work fine that way. Carefully check the clearance between the top of the valve guide and the bottom of the retainer, around the keeper area. This tends to hit when using a higher lift cam. DD

All valve stems wiggles like twanged strings. So keep this in consideration also. I saw a high speed video of valve vibrations while ago on youtube. http://www.youtube.com/watch?v=i_NpzU4p ... re=related Cheers, Wizard |

I have never-ever broken a spring retainer. What are your spring pressures, on the seat and at full valve lift? DD |

Quote: 91-101 lbs @ 1.650 & 231-245 lbs @ 1.220 lift
If these springs install at this rating, you will be fine.They will be fine even if installed slightly "taller", like at 1.700 "on the seat". How much valve lift is on your cam? DD |
