    Alky VS Gas

    Ive got a 632 BBC, 15.5 CR with BB3 Xtra heads ported. Im currently running a Birdcatcher enderle alky injection on a ram. I have been offerd to swap for a Dart tunnel tall deck ram with Twin 1360 Chuck nuytten modified Dominators on C16 race fuel. What do you guys think? Now this is my first drag motor also. Is it worth it????

    You will make more horsepower on gas. I would switch to a fuel like C-14 or C-14+ instead of the C-16 however.

    It takes the right setup on a bigger motor 600+ inch's. Mainly the cam for alky, there is a difference which most dont realize. I wouldnt be suprised to see that size of a motor with 2 gas dominators pick up HP for sure. I am going to disagree going to C-14, run C-16 in it. Remember the cost difference in alky vs the c-16. Both can be made to work to there potential but its harder with the alky just because it takes a perfect cam.

    You can run the C16 in this engine without a problem, however you will be leaving power on the table. C16 is designed for forced induction engines or nitrous engines not naturally asperated engines. If yougo to VP's website and look at their fuel recomendations you can pick the fuel that you need for the application that you have. also if you still have questions you can call their tech line and they are pretty helpfull. If you run the C16 and the C14 or C14+ back to back on the dyno with this engine combo I will bet the farm that the 14 will make more power and still be very safe against detonation.

    I agree with Hammertime on not using the C14 or C14+. But I would use Q16 instead of C16. My dyno guy gained 20 hp on his 540 by changing from C16 to Q16. He had to jet 3 or 4 sizes. I also know of a lot of people switching over to the Q16. I don't know any prices on it, but I believe it is a little expensive though.
