Re: Urgent: Need Advice On 454 BBC Headers For 71 Nova
A 454 is a big motor and it needs big headers. Me and my friends make fun of big blocks when we see small block-sized 1 3/4 headers on a nice Rat motor. Might as well keep the exhaust manifolds. "You need back pressure" is a myth that header companies tell you when they want you to buy their inferior cheap, small tube headers or small mufflers.
