Explorer heads Reply #30 – April 03, 2007, 03:13:08 PM hey vinnie, so you said that you will sell the GT40 heads right? if they are the true GT40 (not the gt40p's) i'll buy them from you! Quote Selected
Explorer heads Reply #31 – April 03, 2007, 11:37:30 PM GT-40P heads actually out flow the regular GT-40 iron heads. The chamber is actually a better design. The only down side is that the FMS headers require *slight mods* to the stock motor mounts:hick: Quote Selected

Explorer heads Reply #33 – April 04, 2007, 12:16:18 AM If you get anything more than a stock HO cam, you must change the pistons. The SO has flat tops and they wont clear the valves with a bigger cam iirc. Quote Selected

If you want to run a B303 with an auto you'll need a higher stall torque converter and a trans cooler. Do a little research and see what combos make the power you want. Don't always go for the bigger is better mentality. All this stuff costs $$$$$ so be sure you get what you want. If you want to do anything other than stock a stock HO conversion YOU NEED HO PISTONS.

Explorer heads Reply #37 – April 10, 2007, 04:52:22 PM How do you tell GT40s from GT40Ps by looking at them? Also, I have a Mustang Kmember, and urethane mounts, will I have clearance issues? Quote Selected
Explorer heads Reply #38 – April 11, 2007, 01:06:10 AM Gt-40Ps have have GTP stamped on the head under the valve cover as well as GTP at the front corner of each head. The plugs stick out much straighter than standard Ford small block heads as well. You shouldn't have a problem putting them in as you have a Mustang K member and mounts. The swap headers should fit no problem as they were designed to clear the Mustang mounts. I had to cut a little bit out of my drivers side mount for the FMS headers to fit but I have the stock T-bird mounts. Quote Selected

Explorer heads Reply #43 – April 17, 2007, 11:56:52 AM *should* have a set before the week is out if it stops this rain/cold shiznit. I'll keep posted. Quote Selected
Explorer heads Reply #44 – April 18, 2007, 02:13:53 AM If you get the *P* heads make sure you get the FMS stainless shorties for them. They fit around the plugs great and since you have an '84 they won't hit the mounts. Quote Selected
