Yes , but you would have to change the intake manifold also
check the vin for the 5th number and that will tell you the engine size a or c =460ci f= 302ci h=351ci s=400ci The fifth position of my F150's VIN is an "N". What engine type is that ? ----------------------------------------------------------------------- The truck VIN's are different from the cars I'll give an example of a 1978 Ford F150 VIN # (F14SLRE7485) 1st , 2nd , 3rd , is the series ( F14 indicates F150 4 wheel drive ) 4th is the engine type ( S indicates a 400 V8 2 barrel carb ) 5th is the assembly plant ( L indicates Michigan Truck ) ( " N " Norfolk Va) 6th through 11th is serial number On a 1978 Ford Truck the engine codes are as follows : ( 4th " character " ) A - 460 v8 - 4 barrel carb. B - 300 straight 6 cyl C - 300 straight 6 cyl ( economy ) G - 302 V8 - 2 barrel carb H - 351 V8 - 2 barrel carb ( modified ) J - 460 V8 - 4 barrel carb S - 400 V8 - 2 barrel carb Hope this helps ( Helpfull )
If you have a 400 ci, the horse power was down to 250 with a 4 barrel carb.
scewed in front of carb,the as line hooks into it.
The 400 in the 1979 F150 has a 2 barrel carburetor , so unless your willing to change the intake manifold to a 4 barrel manifold and get a 4 barrel carburetor , I would stick with original equipment
Adjust carb on 400 Polaris 4x4 2stroke
From 350 to 450 depends on carb size and how big of cam u use and put headers on it and a good high rise intake and a 750 Holley to get over 400 and 400 torque Get the thinnest gaskets for those heads u can use and have them ported and polished .
about $ 400
Material and labor... about $400.
About 400-500 dollars
Around $400 for a new install.
Need more info like year, make , model, 2 or 4 barrel carb, standard or automatic transmission.
I'm not sure of what you have looked at already. check your idle pump,if you're still running the two barrel carb.(2100-or-2300). it will be on the right hand front of the carb. linkage is connected to it as you feed the carb.(move the throtle by hand you can see this move). if it leaks even a little bit that's the prob. 4 quarter inch screws and 2.00 part will fix it! toolman-ou812@hotmail.com is me.
