Default Think it should hit mid 9??

5.3 Lm7 block, with stock crank, ls2 rods with L33 Flat tops, ported 806 heads, truck coils from a 6.0, NX3 and a carbed setup with a 750 Dominator carb. Going to a 250-275 shot on a cheater plate and NX bottom drop solenoids. Car weighs around 2900 and has a glide with a brake and 4.11

What's an NX3? I think going with any 4500 flanged carb is overkill and not needed.

It should run easily into the 9's with a good tune and if it hooks well.

Edit: I just found out what an NX3 is. An old line of Nitrous Express camshafts not made anymore. 235/239 is a healthy duration on that cam for a 5.3 Throw it in there! car is light enough for it.

yea im getting the complete top end from a member on here who has been a ton of help for me so far. reason im using the 4500 flange is becuase thats what i have from my last motor and it being only a 750 i figured i would try it. Dont really want to shell out for a 4150 at the moment. Im anxious to see how it runs tho!

In my experience, Dominators are not very good street carbs. They are more on the strip only side of things.
