Re: 69 L78...go pure stock or???????
Eric pretty much nailed. I wouldn't worry about porting/extrude honing your exhaust manifolds...there's easier power to be had elsewhere, and you're gonna waste a lot of time/money and have little to show for it. Also, if you're gonna run at the Pure Stock events, you'll have to ditch the 454 for a correct 396 mill, or move to the "Stock Appearing" class...
