I just got my holley 6231 carb in my fifth ave and it runs great. had one little problem with the electric choke not working so i took it off and will be replacing it with a manual choke tomorrow. even though the carb was meant for a 413 motorhome engine it works great on my 318. now it has better torque and overall hp on the top end. not sure how much ive got now but its definately noticable. next will probably be a 100 shot of nos or a cam swap. still looking for a useable 8.25 inch rear end.

 

I know, I dont like electric chokes ither, I never hook mine up. even the manual s, I dont hook the arm up from the choke well.

 

it gets pretty cold here in the winter so its kinda something i need.
