Holley Carb Bolt on to Stock Intake. #2596745 12/25/18 02:40 PM 12/25/18 02:40 PM

TimS OP top fuel Joined: Jan 2003 Posts: 2,179 Walton, Indiana	I've tried a 4160 series carb that would not bolt straight up to my 69 Roadrunner 383HP stock intake. Is it possible to get a 600 or 750 Holley square bore that will bolt right up without an adapter plate of some kind? 1968 Barracuda Fastback 318-2BBL 904 2.76 Frost Blue Survivor 1970 Roadrunner 440+6 BBL 727 AT 4.10 SG Dana Blue Fire Metallic 1971 Cuda 340-4 BBL 4spd 3.91 SG Curious Yellow 1972 Barracuda 318-2 BBL 904 AT 3.23 1 Legger Tor Red/White Vinyl Top 2007 Dodge Ram 1500 5.7 Hemi AT Patriot Blue 2011 Dodge Challenger RT 5.7 Hemi 6spd 392 SG Triple Black 2014 Dodge Charger RT Max AWD 5.7 Hemi AT 305 Billet Silver

Is it the bolt pattern, or the Holley linkage getting in the way of being able to tighten the carb properly? It might not need an adapter, but a small spacer to raise the linkage so it doesn't hit the intake.

The carb I started the fit with also had an electric choke. The choke idle screw hit the intake on the rh side. The LH side throttle linkage that hangs down hit on the left side of the intake. I suppose I need a spacer to raise that carb up a bit? 1968 Barracuda Fastback 318-2BBL 904 2.76 Frost Blue Survivor 1970 Roadrunner 440+6 BBL 727 AT 4.10 SG Dana Blue Fire Metallic 1971 Cuda 340-4 BBL 4spd 3.91 SG Curious Yellow 1972 Barracuda 318-2 BBL 904 AT 3.23 1 Legger Tor Red/White Vinyl Top 2007 Dodge Ram 1500 5.7 Hemi AT Patriot Blue 2011 Dodge Challenger RT 5.7 Hemi 6spd 392 SG Triple Black 2014 Dodge Charger RT Max AWD 5.7 Hemi AT 305 Billet Silver

I need 1 11/16 for the 750cfm I want to use. 1968 Barracuda Fastback 318-2BBL 904 2.76 Frost Blue Survivor 1970 Roadrunner 440+6 BBL 727 AT 4.10 SG Dana Blue Fire Metallic 1971 Cuda 340-4 BBL 4spd 3.91 SG Curious Yellow 1972 Barracuda 318-2 BBL 904 AT 3.23 1 Legger Tor Red/White Vinyl Top 2007 Dodge Ram 1500 5.7 Hemi AT Patriot Blue 2011 Dodge Challenger RT 5.7 Hemi 6spd 392 SG Triple Black 2014 Dodge Charger RT Max AWD 5.7 Hemi AT 305 Billet Silver

Put a carter on it and everything works. I ran the AVS my '69 383 Super Bee came with for a while. It was "OK, but wasn't exactly impressive, either. Some BB Mopars came with factory Holley 4160s in 1970 & 1971, so it's not like the factory wasn't open to alternatives to Carter.
