Hello, I have a 1969 fastback and recently I put in a 302 bored .30 over, B cam, roller pedestal rockers, and a Holley carb with the number L6R1B (Not sure on the CFM size, assuming 600) and that is connected to a T5 Ford Racing Transmission and Ford 9" with 3.73 gears. Sorry for all the information but I am trying to narrow it down since I know all those questions will be asked anyway. The current carburetor is a regular $320 one from Autozone and recently it has been studdering under mid RPM throttle hits. That is not the question that I am wondering, I am wondering what the best carburetor setup would be for this car with the given info and that it is also my daily with mostly city driving and a decent amount of short distance highway. I know this might sound redundant but I want to have the best MPG's and also the most power possible. I would rather sacrifice the MPG part of course. Thanks to everyone in advance as I am new to the forum but not new to the daily driven classic car struggle!
Decided to go the full Holley Sniper system with EFI throttle body and HyperSpark ignition. The Sniper ECU now controls my air/fuel, idle speed, spark timing and cooling fans. There are many ways to do this. Here is my way with pictures and part numbers. (My thanks to Chris at https://www.efisystempro.com/ for the tech support).
So I'm days away from rebuilding my engine. 351W I'm going to put a 400hp edelbrock top end kit in bored 30 and redo the bottom end. I bought a 650 Holley carb a little over half a year ago. Should I just use that or put a FiTech EFI/Holley EFI on this? I've heard great things about the Fitech and to buy it before Holley buys them out. I've heard that people have a hard time tuning on them at first. Has anyone had experience with this?
Hi guys, I've been looking at this site for a while and just decided to sign up. I've been having problems getting my car to run while in gear or in idle sometimes as well. The motor is a 331 stroker with tri y headers, weiand intake, holley 4160, procomp heads (yeah I know), an edelbrock 351 cam, and msd box (not the 6al) The car hasn't been started in about 3 months and during that time I put in a new gas tank, and changed the pcv system to allow use of a breather. I have ford racing slant valve covers with a breather and a oil cap feeding to the carb on the other side. Before it ran fine. I've tried to adjust the idle mixture screws and the idle speed screws but to no avail. It idles fine above 1000, but lower it and it wants to die. Put it in gear and it starts choking right away. I was wondering if I should get a rebuild kit and try that as dust may have fallen in the barrels, and I know I have a carb to msnifolf leak as the rpms shoot up when spraying around the base of the carb. Any ideas are welcome! I'm not too familiar with carbs and this is my first one. Thanks
