    $5770 shipped to you from JEGS, (357 hp/400Tq) complete with frontrunner and all accessories! Sounds like a pretty good deal to me... If one wants more power, they also have 375 and 385 hp versions! Power probably is based on headers since exhaust manifolds is about the only parts the engine needs which isn't included. What is the best iron exhaust manifolds for Vortec heads??

    PS. Curious why a 9.0 compression engine requires high octane fuel?

    Carbs aren't that bad..........My 56 has a stock rebuilt 350, 700R4, and 3:42 gears. 29 inch tall tires. I've gotten close to 20 miles to the gallon with this set up with the A/C on. I don't know that I'd improve it much with FI. I'm afraid to change anything.

    Yes that is the engine I got and I got it at Jegs.

    I also wondered about the premium fuel requirement. Is it possible that is required for maximum horse power?

    I'm thinking about the 2 1/2 inch rams horn exhaust manifolds. I think they will work okay.

    I believe you, my 55 with a 396, 2x4s and a TKO-600 with a 3.54 gear get close to that on highway.

    If the exhaust port locations/bolt holes are consistent with old style Chevy heads, then the 2.5" ramshorns would be a good exhaust for this engine. Let us know what you do and how it works out..
