I assume you’re going to go with direct/straight linkage. I just ordered some #48 and #49 jets and 5.5 psi PVs for my 2 x 2 direct/straight setup from Vintage Speed. I’m also going to try a progressive linkage. For that setup, went with #51 jets and a 5.5 psi PV for the primary. For the secondary, went with #48 jets, and a plugged PV for the secondary. I’m using a vintage Edmunds 2x2 intake which allows for the stk generator mounting. Charlie from Vintage Speed recommended the stuff for the progressive setup, and I just Googled the stuff for the direct/straight setup. Will know in a couple months how each works once the snow melts and I can get my speedster back
Outside.
