this was on a Holley 850 dp. 1 3/4 throttle blades. As well, does anyone know if the accelerator pump cams available work on the 30cc and 50cc pumps? Thanks
Yeah the throttle bore spacing looks 850 and they use 1-3/4" blades . From what I can see looks like front cam is 30cc narrow cam . Rear looks like wider 50cc cam . Looks like a #330 pink cam which is ok . #664 is normal 50cc cam . Rear arm looks like a 50cc arm . Not sure on the front cam . Kinda looks like a speedmaster unit . I've used one before on an 850 - QC was a little suspect in a couple areas . Definitely don't use the metering blocks .
Post the Holley list number from the front of the choke tower . If a 4 corner idle body make sure the rear metering block is also . That base should be a 4 corner style . They all have to match to be 4 corner .
yep , body should be 4 corner . check rear metering block and i think it should be rear power valve also . if you need oem spec for jets etc let me know .
