		| I have a 67 Mustang witha 390between the towers. I love the engine but I want to upgrade to a 427. What do I look for when looking for a 427. I can't seem to find much info on them except that I've heard topoiler, sideoiler, and centeroiler all used. I do know the basic differences between the low, medium, high rise heads although any extra info on them is also welcome. Thank you for any replies. FE  |
