Hello all
Thanks for trying to help.
It's definately a B not a 3. I have also seen a list (can't find the link right now, did a search on another puter) where 34R9716-3 is ekvivalent to 122-56. 56 is a very small jetsize and i think not the original one for a Holley 600 model 4160 ?
The problem in the first place was a slight pinging when I stomped the gaspedal hard and mostly on lower rpm. I have, in the meantime I gather some information about the secondary plate, changed the primary jets from the original 66 to 68 and voila' The pinging is gone and theres even more G forces when accelerating
My setup is 351C 2V heads with 4V Edelbrock performance intake and a mild cam which lifts 0.500 " with 1.73 Harland Sharp rockers (I have no clue about the the degrees and overlap of the cam)
I use oldtime TRW 2408F forged "popup" pistongs which give me about 11.5:1 in compression ratio :devil: . Mallory comp9000 @ 18 degree BDT on idle 900 rpm and 40 degrees @ 4000 rpm. Vacum at the carb foot is 10.8" HG idling. I use the yellow spring at secondary vacumports.
Isolated headers and then straight out trough one muffler at each side.
I live in Sweden so I use the 98 octane we have here from the pumps :ylsup:
It's my first V8 rebuild and I wonder how many HP I have with this setup ?
I don't think I have ever felt a better push then in this car. It's also really streetable. Hell breaks loose at about 3500 rpm up to 5500.:flamer:
I want to document as much as possible so it would have been really nice to know about this plate. I want take te carb of one more time to measure the holes
. Anyway, we don't have drills in inches easily available here.
Come on now, there must be someone who knows about this jet-plate ?
Oh and Catman, I have been at Holleys and searched without result. I have also asked them and will maybe have an answer when they start to work this week after the weekend.
