Accel or Bosch injectors?
I need a set of 36lb injectors for my new "sort of" L-98 build - no more TPI, Holley single plane EFI manifold, aluminum Vortec's .560/.581 lift. I'm wondering if anyone has used the Accel injectors or should I just stick with the Bosch injectors.
It should be in the 425-450 hp range, hence the 36lb requirement.

Probably, but I'm doing new parts wherever possible and since these aren't stock/OEM parts I think I'd rather just pop for new. I thought about getting new LS2 injectors, but I think I want a little more flow. Still waiting to hear back from Mark at PCMofNC when he gets back to work on Tuesday.

I used 30# injectors on my 383 with a larger cam turning low 11's spinning 6300 rpms. I am now using 36# on my 406 turning 6700 rpms running low 10's. Might want to double check that you need 36# on a 350.

I'm running Accel injectors in both my 99 Suburban that has an 0411 PCM (GM EFI) and 85 Corvette with Holley EFI. The ones in the Suburban have been it for a few years now and perform well. (Has a mildly built 355 Vortec and the same model # injectors you're asking about.) The ones in the 85 have been in for three seasons and have also taken the punishment of living in the high heat under the hood and higher fuel pressures during boost quite well. I've got no complaints with the sets in either vehicle.

Mark said to go between 30 and 36 pound, so I was leaning towards the high end thinking it would reduce duty cycle. I'll double check with him.

It will reduce duty cycles but that only matters up to a point. AFAIK, you need to keep it about 80 to 90? You don't want it too low either
