1.50 isky solid roller valve springs and del west retainers These were dyno take offs from hendrick motor sports. So they basically take a 800 dollar set of springs and do a few dyno pulls then sell them. I paid 300 for them a few years ago and ran them on my 396 lt1 that made 570 na rwhp for about 5000 miles most of it was sat night street racing and twice to the track. I had a 670 lift solid roller which when I got them I asked the nascar engine guys and they said they would never break with that little cam so who knows what they throw at them for cam lift. They are 1.50 out side measurement with a caliper. I had them set up at 325 on the seat and 680 open if I remember correctly and turned that 392 7800 rpms with no valve float. When I pulled them I checked them all and they all were with in 5 lbs of each other at the exact installed height. The retainers alone are 200 to 300 bucks so asking 150 for it all is more than a fair price for some one needing some high end stuff for a steal. I just will never use them again so like to help someone get a project done rather than just let them sit. I have lost most of the keepers 10 degree most likely but have 9 of them still so can match up what you need to get the rest of them. this is a once in a life time deal they are some special tooled steel for 10,000 rpm use so street and drag race will never break something made to turn 10k for sustained use. any questions just ask. |
Re: 1.50 isky solid roller valve springs and del west retainers you cannot get a better spring for the price cant believe no interest on this. Guess no na big motor solid cam cars left or projects. |

Since ran just cleaned and boxed up https://cimg0.ibsrv.net/gimg/www.thi...538f5a3af.jpeg https://cimg1.ibsrv.net/gimg/www.thi...679965add.jpeg Del west retainers in great shape bottoms have very little to no seat wear. https://cimg2.ibsrv.net/gimg/www.thi...352bb8028.jpeg https://cimg3.ibsrv.net/gimg/www.thi...e74123299.jpeg |
Re: 1.50 isky solid roller valve springs and del west retainers Would these be too much for a 355 with edelbrock performer rpm e-tec heads with 1:6 roller rockers with comp xfi 268 cam? |

They are a gm performance part not sure of part number. Know we're setup 130 on seat and around 350 open which is good for a roller cam like yours. Same ones came on a lot of gm performance heads like fast burns at one point and all the bow tie race heads. We were using a solid roller in that car so took of right out of the box and had them since. |
