I understand the draw of a big block cross ram they are rare and just look badass. But as previously stated if top numbers are your goal in a normally aspirated motor tunnel rams pretty much are the top of the food chain. I have seen test s on unprepared cross Rams and the numbers are even below a good six pack, but as mentioned there is horsepower to be made with epoxy and popsicle sticks to improve air and fuel delivery. But my car is 95% street car and overall presentation and rarity lead my build not 20 horsepower.
