Throttle body help

Post by 81J10 »

I recently bought a truck with a 4.6L stroker, mild crane cam, and a carb. I have purchased a Mopar EFI kit for it that has 19# injectors. I
have read that most use 24# injectors for these, I'm not looking for major HP but need to know if I need to increase the size of the throttle body
for this setup to work. Do you need to buy a unichip or other for all of this to work right? Is the 62 throttle body important or something that
can wait? What about injectors? do they need to be done right away or will the injection work OK as it stands with the 19# injectors? 91 Block ,12 counterweight crank. Also I have no idea what the guy used for pistons, And not sure I understand why I read that your dishing pistons and decking the head. Seems like you raise compression with the decking and reduce it by dishing. What's the advantage?
Thanks For the help.

You deck the block to get a better quench. The pistons are dished to lower the compression...that decking the block raised. Most are decking the head just enough to make sure its flat.
