Picked up some GT 40 P heads - Page 3

w2zero · #31 09-23-2009, 11:11 PM

Should be a dandy combination for the street. Lotsa hp and lumpy sounding too. I have the P heads, B303 cam 1.72 rockers with port and polish in a standard bore with flat top slugs zero deck. It pleases me.

A porting site I will use with my extra p heads is here. http://www.diyporting.com/gtpex.html

and some of my projects here. http://s6.photobucket.com/albums/y237/w2zero/

W2 I had lost this thanks for the re post .

I'm glad I found it since I overported my original set of p's on the exhaust side. Not that it makes a heck of a lot of difference for my purposes.

Yeah from the reading they flow real good out the box .

I polished the combustion chambers the exhaust runners to a mirror finish to reject heat. Likewise the valve faces and backs. Maybe if I make some cash from my intake fabrications I can afford aluminum heads one day.

These flow real close to big dollar aluminum . Makes great for the street

I've been running these for about ten years and do like them a lot. My exhaust is a bit of a problem though. In a 64 Fairlane, there just aint a lot of choice for headers. Hooker, Dougs, and one other make some for it but they are way spendy. Throwing the p's plug angle into the mix makes for header removal to change one of the plugs. Consequently, I am running HiPo cast exhaust that has been port matched to the heads.

Yes a post on here about the issue with them in street rods . Sanderson does make them again as you say pricey .

I may yet buy a cheap set of Mustang headers and cut them up and make them fit the Fairlane with the odd plug angle on the p's. Could actually make that into a business model.

Would work bring the exhaust ports down in the front of firewall.

The cheapy Mustang headers would need a lot of work to direct the exhaust correctly in an 'A' - I tried it!!!! Then spent the bucks for some uncoated Sanderson's, cleaned up their mistakes in the gas path then had them Jet Hot coated rather then some vendor's unknown quality coating that Sanderson uses.

Bobby - that photo will give you some idea of where the motor mounts are as far as height.

and the other side....http://i70.photobucket.com/albums/i8...DSC_0050-1.jpg

Thanks Dave again the Sandersons are about the only candidate that will work easily

Bobby, I think it also depends on where you intend to run the exhaust pipes rearward....will you route them through the X-member or under it? I have the Sanderson headers for mine too but I haven't completely decided the path for the exhaust.....

Hey guys just got out of hospital last night . Ticker was tocking a little will say angiogram's really suck .

Randy really far from that Idea yet . just received everything to get the flatty fired to sell it . Then all the suspension has to go .

That sucks, but at least you went to the hosp.. Take care of yourself so you can keep on your projects.

My cousin had some chest/arm pain and his doc scheduled him for a stress test the next day. The went looking for him when he didn't show up. You know the rest. Wish I had been there to ride his ass to the ER for a read on a 12 lead ASAP.
