HEADERS AND CAMSHAFT Questions
Hello All,
I am rebuilding a 460 to go into my 1978 F150. I have two questions.
1.What name brand, type, make, part number header will be good for this application?(I wish that it wouldn't leak also 8) As Ford didn't put the 460 in that year no one I have tried has a listing.
2. Has anyone used the Comp. Cams camshaft for the 4X4. They call it there Torque Monster Duration intake 234, exhaust 244, Lift intake 564 and exhaust 570. What I want is a cam with a lope but has some low - mid range pulling power.
Thanks to all that reply, you may email me at ga1998(No Email Addresses In Posts!).

You might try E-mailing Advance Adapters in Calif.
for the headers: sales@advanceadapters.com
If they don't make them they may know who does.
As far as the cam is concerned it sounds like you would be over-cammed. Is that duration at .050 thousands or just advertised duration? The number one mistake most people make is buying too large of a cam or carb. I would call a couple of the major cam vendors and get their recommendations. You would probably be better off with around 212 degrees duration at .050. A few years ago I had a 460 in a 1978 F250 with C-6, headers/dual exhaust,
3.55 gears, alum. intake, and 750 Holley. I stuck in a cam with with around 220 degrees duration intake/exhaust...just as the truck would start to make H.P. the tranny would shift to the next gear(about 4,000 R.P.M.). I would have been better off with a smaller cam or I should have changed to 4.11s or 4.56s to make use of the H.P. range of the larger cam. I called Comp. cams recently since my current truck is used for towing (89 F250, 460, C-6, headers, dual exhaust, EFI injection, 3.55 gears) their recommendation was a special grind with a duration of 206 intake and 212 exhaust. One other thing...the cam you were looking at has a very high lift for a stock 460...if you end up using it you will need to convert your valve train to the 1969-71 Cobra Jet style used in the factory hot-rods of that era...get the Ford SVO Catalog from a local Ford dealership.
