My vote is for the 4.5 as well. I've used the 4.5, 5. and 8.3. The 4.5 will make that power no problem, it's super efficient, and lower profile. 565514

Looks great. That should work very well for you, and I bet upgrading to a quick fuel 1050 4150 carb or something similar down the road will pick up a fair bit more power too. Nice build.

Looks like you could've pulled a few jets out for sure. For cam duration vs cylinder head comparisons, here's a very similar combo with a lunati 238/248 114. Same cubes, same heads, a little less...

The hp rating is just based off of the injector sizing. Theoretically it will support 650, but depending on the bsfc, and airflow requirement of your combo it might be less.
