Opinions on what options to purchase

[Herkypilot]

I am looking at purchasing a 351W High Performance Engine W/420HP from Performance Unlimited in NJ. This motor is "turn-key" and is specifically built for Cobra kits. The motor will be about $6,600 after applying the 3% internet discount to the order. Looking at the spec sheet at the following web page:

Performance Unlimited

I plan on purchasing a Hurricane kit to put it in and this motor matched up with a TKO 600 should work nicely.

Is there any options worth considering that this motor doesn't have and should I go with the electric choke and 650 CFM carb as indicated below?

600 CFM Edelbrock Carburetor. (Manual Or Electric Choke) Or The Edelbrock 650CFM AVS Series Carb For $75.00 Additional

Is this motor worth the money?

Thanks
