Any one know how the Comp XE-262H cam will sound and perform in a 302? I am building a 74 302 the block is D4DE the heads are D3UE I have not decided on the intake yet. I have removed the thermactor bump in the exhaust ports and rounded out that area as well as port matched the intake and exhaust. I went with hypereutectic pistons flat tops with "eyebrow" valve reliefs. I have to admit I have been somewhat scared off by the topic of headers I mean both price and having to relocate the shifter from the column as well as the power steering bracket stuff. I was hoping to modify the manifolds and just run them ( looks like that passenger side manifold will flow like crap tho) are there any interchanges for that? anyways just trying to make a presence on here and learn more about these cars in the process. I have been glued to the ford trucks dot com website up until recently. time for something a little different. and thoughts or comments are appreciated thanks.
I forget the number but I have a extreme 4x4 cam in my 289, as for sound its kinda dissapointing but the power it makes is nice. I would have gotten the bigger one if I new it was gonna sound so mild. Its around the 260 somthing range 1200 to 5200 power band with lots of torque down low
I am just wondering I used the XE274 in my 390 and I love it.... perfect amount of lope and retarded performance right from idle to 7000.... I thought that these camshafts affected the small block stuff a little more violently and I also wanted to stay mild as I might run a stock 2 barrel manifold ported with a 480CFM autolite carb as I have some dozen or so of them kickin around. see the car was completely number matching (from what I could tell) when I picked her up.
If you go with the XE series cam with stock heads, you'll also need to have screw in studs and guide plates installed. These cams will pull the stock pressed in studs right out of the heads.
I have an old school Cam Dynamics 266 in my truck with a 302. It is pretty much a single pattern version with similar specs as the exhaust on the 262 you are looking at. 5500 rpm and it is all out of power, but it works real good with the 3.00 gear. Actually gets a little better gas mileage than the stock cam. It has just a hint of a lope at cold idle but goes away when warmed. My opinion, screw in studs, guide plates, and hardened push rods is an expensive proposition for a set of D3 heads. You could get away with crosspinning the studs and use your old rockers with the specified springs. A later set of E7 heads that use the pedestal rockers and bolts can be had cheap and can be made to flow better than the D3s. Just my 2 cents Cleaver
the D3 heads are existing and what I have to work with. The guy doing my machine work (other than the porting and polishing I did myself) figures the studs are already screw in type. I am not looking for expensive fix "just a touch of evil" nothing to crazy that is what my 65f100 with the 390 is for..
