Updating Carbs

I used the Price Motorsports 351 dual quad intake with Holley 1848-1 carbs. Ran like a raped ape.

Just to clarify, the Edelbrock setup is going on my 408. The heads are Victor Jr's. I ordered 2 of the 1940 kits from Summit. BOTH freaking kits came in already opened/used (one kit the person using it had dirty hands). Summit sent out replacement kits next day, then the warehouse forgot to send them on a Friday, so it ended up taking til the following week to get them, but they're here and ready. My 351 has the Price setup with Holleys and Promaxx heads.

I have Victor Jr heads as well. Just the cams are different. 235/238 @ .050, 299/302 dur, lift I=.573 E=.582, LSA 112, 10in of vac best case.
Timing at 12deg initial, all in at 3000, 36deg full.

I only switched the primaries jets, rods,

#4 on the tuning plot page 33 of the tuning guide.
part#1424 (.089") primary jets
part#1445 (.065"x.047") rods
Just switched yesterday from orange (stock 5hg) step-up springs to yellow (4hg) to see if the orange springs are lifting the rods and adding to the rich.
Have not driven yet.

Linkage: Holley Sniper dual quad kit. Use the 7.25" rod. for the Price intake, 5" will work on the Edelbrock intake (I think) https://www.summitracing.com/parts/SNE-20-43

Linkage bushings: 2 each kits. You only need the washer and step bushing in the kits. https://www.summitracing.com/parts/MRG-1512

I use heat shrink on the rod jam nuts/shaft to prevent loosening.

Just wanted to take a minute to thank Sycraft for starting this thread, and Spdbrake for your input so far. The inclusion of pictures, part numbers and the results, good or bad, are saving me and others like me not only money, but TIME. I for one, really get into the minutiae (ex., changing out secondary springs, linkage part numbers, et al). Even if I don't go with exactly what another may have, seeing a part actually installed and reading the user's feedback is like gold. In my case, I now have a much clearer picture of what's needed to get my engines finished off, into the dyno room, and ultimately nestled between the frame rails of their respective cars. I will post future updates in my 3-engine build thread, so as not to further hijack this thread. Keep the info coming and thanks again.

That's a great look, just wanted to post it to appear without clicking a photobucet link (I'm a Caveman trying to learn about this scaaaary world) Wondering if you used the Medicemfg.com adapter set to fit the valve covers? I'm still not totally nailed down on which of the 6 sets of valve covers at my disposal I'll ultimately use, but I have a set of these adapters, but no chrome pent-roofs. Not sure but i believe my Holleys are 390cfm each, looks like you have 465cfm each. Curious as to how well theyll perform. Were going to find out in the very near future.
