Oooo, thank for the info on the spacer.
I’ll throw another option into the discussion; FiTech fuel injection. It’s a bolt on operation, and I think you will be pleasantly surprised by the performance and fuel economy improvements. I put on on my ‘55.I need help. My friends are split on which is the better carb. Most of them do not have tbirds. Would appreciate other opinions on this. Thanks Spider
Hi, I just installed an Holley Street Avenger 670 cfm yesterday and boys what a hell of a difference! I have a Q code 428 ci and th original carb was Autolite which is 480 cfm if I don't mistake. I never been able to get the tranny shift at 4600 rpm and my engine rev it this afternoon. I had to calm myself! Next step will be Edelbrock Performer RPM Intake #7105 or Blue Thunder FE Intake. MSD A6 box and distributor. New 3.50 axle gear, mild cam and maybe Sanderson Headers FF394-SEC specially made for T Birds (390 or 428ci). Actually, my rear tires height are 29 inches, it's gonna help the engine with the 3.50 gear. Don't be shy to go with a 650, 670 and even a 770 cfm if you are planning to update your engine. Good luck!
Hey guys, these are double pumpers, not vacuum actuated secondaries, right?
