TTI header clearence on a 65 Valiant

65 Valiant said
so 1.06" bars will be difficult,hm??
i have the stock 0.76"bars and could get 0.89"ones from a friend,but everything on the car is for performance on the street and the 360 engine weighs a lot more than a /6
aren't the 0.89"one too skinny for performance?

0.89" was the factory size for A-body with big block that was used with the later heavier body style. They're very stiff on an early A small block but that's just my opinion. Some people like hard tail Harley's.
