Installing 48 IDAs

[Pmccooey]

I’m planning on installing a set of Weber 48 IDAs that I picked up from an estate. The carbs were done by Jim Inglese but I have no idea what type of engine they were jetted for. I plan on stripping g them down, cleaning them up and setting them up for my car just to get it started and tune from there. So I’m looking for a little help as I’ve never ear done Webers before but have been reading and going through as many tips as I can find.

Currently have a Contemporary Cobra with a 427FE, mild cam, 750 double pumper, mechanical fuel pump on the block, toploader, Jag IRS at 2.88 (but looking to swap those gears out this winter also for 3.54 or 3.73). I’m in lower NY so about 300’ above sea level. Car just sees local driving with an occasional spirited blast to open her up.

I’ve been looking around for same base setups for jetting and pumps on the Weber to get rough start. I’ve found two for a 427FE but they seem to be quite different.

Can I run my mechanical fuel pump to a pressure regulator dead headed to the Webers? Otherwise I’d need to pull the fuel tank and start a whole new fuel system.

Any other tips or tricks from some Weber people would be greatly appreciated.
