All you guys runnin C-4's.... I have a C-4 i am wanting to put in my 84GT. i have long tube MAC headers for 5-speed, and world products iron heads. My question is, can I use the 164 tooth setup? will the bellhousing cause major issues with the header clearance or trans tunnel clearance? I want to try to use this setup, because I already have a 3000 stall converter for the larger 164 tooth. Thanks in advance for any help!
