i'm with vlad. valve springs.

Since the last Dyno day I've installed a HEI coil, installed a kinugawa wastegate actuator with a 5psi spring in there (should work out to around 4psi boost), an adjustable fuel pressure regulator and a set of 440cc injectors should be arriving tomorrow.

Crowcams have a set of springs that'll fit though that does mean the head needs to come off. I'll see how far I get with the lower boost and maybe the HEI coil picks up a little up top otherwise it's time for springs.

No luck with cams or springs, crowcams don't carry anything for these motors anymore. I'll pull a spring and measure it and try find something close.

Still waiting on a boost tee so I'm stuck at 3.5psi wastegate pressure. 71kw at the wheels is pretty good from 50kw and at only 3.5psi.

Idle bpw is under the minimum injector pulse width so fueling at idle isn't very good. Even using single fire mode. Compromises.

Looks good, I love this project.... For the injectors struggling at minimum it can help to adjust the idle AFRs up a bit for a slightly rich idle. You'll get slightly more fuel injected without having to cheat the VE table or anything else, and you might find you can get it to idle not quite too rich but more stable with slightly longer injection pulse.
