Asking on behalf of the "modders" out there. Will these springs work with a Crane H272 cam (.454/.480 lift), without additional head work for spring clearance?
Asking because stock (and most other "single" springs) require machining so that the coils won't bind at full lift.
Just realized I had the wrong part number listed -corrected. They are 980-12 springs. I have used these springs with a 272 Comp Cam . It was a custom grind for a 3.4L turbo application but IIRC the lift was something like .440/460. The lope with that cam is very noticable. So lets add a caveot. For 90% of all PRACTICAL
street strip applications these springs should accomodate any 60* V6 cam that can be used. No valve spring can be used as a direct fit with every single camshaft made plus if you decide to put a .480 lift 272 cam in your 60* V6 good luck with the ECM handling it and kiss goodbye to smooth running emissions and mileage.
