I have been trying to find a 454 block cheap instead of building this 427 tall deck I have. No luck. The tall deck is in great shape and really think I should just use it. Especially since it was free. It has a steel crank (stock), as I mentioned before I purchased car pistons that should run about 10.3 or so compression with the heads I want. If I purchase a set of 6.5 rods, can I use the stock steel crank and the car pistons? Is there anything I should know before I purchase the rods? I noticed that Edelbrock makes a TD intake manifold (454-R) has anyone used this? Where would I purchase a distributor for this motor? Does anyone have an idea of what HP range it will have and how high of a nitrous shot I will be able to safely run?
