High all, i've been reading, and researching, and wanted to follow up with some questions. Due to circumstances, I won't be running the gt40p heads on my mustang project. I got a bolt lodged in a valve, and had to pull the heads off the explorer long block that was just dropped into my 86 stang. Anyhow, because i'm broke at the moment, the stang will get some ported e7's I have laying around. I'm going to fix the gt4op head in the upcoming months. For my maverick resto, I'm going with an 86 5.0 roller block. It was rebuilt recently with keith black pistons, and has the valve reliefs. It's got a stock cam, but that'll go. The gt40p heads I have, I installed TFS valve springs on, so no problems with float or high rpm's there. I have NO smog on the mav, so that's not a consideration. On a budget, what do you guys consider a decent cam to run, that's got some good lope, and sounds mean, but is still streetable, and will make great power with those heads... A lot of stang guys like the alphabet cams, or the tfs stage one cams, what do you guys think? BTW, in case i'm unclear, these gtp heads are going onto the 5.0 roller block and into the mav. Intake will be a weiand stealth, and an unknown carb which I'll buy upon final install. As well, I read the thread about the new headers that fit the p heads for a mav, but have any of you had luck installing with the OEM exhaust manifolds and p heads? As well, I'll research old threads too, but what budget shorty headers worked for you and the p heads ( I don't want to mod the strut tower). I'll buy shorty plugs if I have to. btw, I'll be running a c4 for now, POSSIBLY an aod in the future. I'm building a car that will likely never even see 1000 miles a year, as the paint/bodywork will be show worthy, However, I want a streetable car with good power, that I can drive anywhere, that's the goal. thanks in advance, Jeremy
I have heard that the stock exhaust manifolds will fit just fine with easy plug access. I put my Ps on and immediately went with Hooker 6901s, and never mounted the exhuast manifolds to verify. I think putting the stock manifolds on will restrict flow and reduce your power...Try to at least ream them out a little before slapping them on.
You are not going to get a lot of loap out of yuor cam and still run a stock converter. If you are going to run a stock converter you need to get a cam that has somewhere between 112 and 114 deg of overlap. If it goes below 112 deg you are going to run into a low manifold vaccume condition and the car will die when you put into gear. (unless you plan on running it at idle at about 1500 rpm or so) The B303 motorsport cam is a nice street cam just bigger than a GT cam. Would probably work well with your app. But there are a lot of cams out there and it is just preference for the application that you are running. If you are going to run a stall converter you can run about any profile cam you want. Hope this helps Don
Your best source for information on cams and engine combinations will always be the cam manufacturers. Comp Cams, Crower, etc. all have tech lines where they will help you decide which of their cams/springs/rockers will help you get the desired results based on your parts combination. I called each of them with my engine /trans /gear /body style /intended use and they gave me their recommendations for all the valve train and what changes I should make to the rest of the combination to have the desired results. I then chose Crower because they are just down the street. Nice people too.
Comp cams talked me into a 268H years ago. Said it was a great street/strip cam. Turns out they were being conservative. Not enough Lope for me. Decent enough cam but I was left wanting a little more. The manufacturers a going to be a bit conservative to avoid low speed drivablility issues.
Jeremy, are you still going to do a roller cam? If so, give me a call. I gotta guy that will grind you a cam to suit your needs, a ford specialist. He did tony's cam and we both know how that thing runs. It shouldnt be much more than purchasing an "off the shelf" cam. Let me know....Jamie
What exactly does a cam do? I have a mild cam in my 302 Maverick, and i notice a power increase, and it sounds cool. how does it help my engine?
a cam is what controls the valves through pushrods and lifters heres a link that your can read http://auto.howstuffworks.com/camshaft.htm
I just read that. I learned what it does. Now i understand how my car bent the push rod and broke the timing chain. It makes sence.
