7petal front half VS 5 petal front half
Has anyone compared a stock 5 petal front half against a 7 petal front half? I have a 225 promax block was cut to 260 specs. It has a 5 petal front half on it. I was just wondering how it would compare to a true 245 carb motor with a 7 petal front end.

a 245 is a nic block with 260 port heights and a 5 peddle front half
a 7 peddle front half adds aprox 25 hp
im my opinion taking your block and adding a 7 peddle front half
should put you modestly @ 260 hp
hope this helps
feel free to call me with any questions...it may be easier
