cam recomendations
i built a 302 with .060 coated hypereutectic speedpro pistons redone heads weiend intake and 600 cfm carb. i also have a melling cam 280 duration and 474 exhaust lift it lopes pretty good and does not burn the tires but that is funny because the old worn out stock engine burned the tires. i talked to an experienced ford engine builder and he thinks it is some sort of rv cam. it has fairly good takeoff but it is getting the power at a higher rpm than i want it to. i did not degree the cam yet but maybe when i do it will straighten up.anyway can anybody find a good low end torque camand post the link here saying that this is my first engine build and i know nothing about cams. thanks

My friend i've told you the cam spec you list are a good choice, but there is one other possibility other than a problem with your motor, and that just maybe your cam was mis labled and you got the wrong one, but any way give these people a call, give them your info and go wiyh what they tell you,

I think in your last thread I made that comment and for some reason at the end of the thread had it in my head you had a rv cam. As mentioned before I agree with strangeranger it is designed for use up there in the rpms and your gonna need gears + high stall to make it work right, or a new cam. If you are on a budget I would say cam and besides it would make your truck operate better all together, your looking for off idle grunt. If we were talking a built BB then maybe you could get away with it, but if I recall you have a mild 351, correct and you probably won't create enough torque to be happy with it? good luck

I dont have that much experience with Ford engines yet I believe I remember someone telling me the 302's are restrictive in the exhaust side of the cylinder head: yes/no?
If this is true would you also not want a dual pattern cam?
As for the 280 cam: if you have not altered your Static Compression Ratio to match the needs of that 280 duration and are using factory stock pistons (low comrpession) then you are asking for trouble.
If this is a daily driver-you really need a cam in the 260 duration range...as mentioned in a previous post. The 280 cam will place your peak hp up in the 6500 rpm range. If your engine never sees the other side of 5000 rpm's then you have mismatched your components with the intention of your vehicle.
As a result your torque at low rpms, with your 280 cam, will be severly compromised.
Kevin,

.060 block, redone heads, hypereutectic coated pistons with valve reliefs that 280 cam .010 under crank wieiend intake 1406 600 cfm carb. i don't know the compression ratio the heads were shaved. just a mild street 302. i did not know anything about cams i just told them something that loped a little i did not know it does this though. i just want something that will be good in an 80 f100 swb, a mustang 2 or a 91 tbird. i want it to have good take off and the power to leave half of my tires on the pavement when i want to show off.i will have headers soon though. i am wanting to get 3.50 gears also

Is this engine now in your truck? With 29-30" tires and 3.50 gears that cam would be an absolute stone unless you're running an automatic with a very high stall speed converter. Even then you'd never get into the working RPM range of the cam on the street.
All this stuff has to work together, you can't just throw random parts at it and think it will be quick.

Tell them while i listen, I dont know why its so hard for people to under stand why they have this big ROMPIDY ROMPIDY motor, and the guy down the street's motor just SCREAMS and he dont have much in it! you cant build a motor to go from a 4700lb. to a 3600lb. to a 2600lb. vehicle, and it perform well in each.

right now it is in an extended cab f150 just to have something to drive while i get the mustangs title fixed or buy the tbird. or i could pick up the 80 model truck but don't think i will. the truck it is in now is totally stock with a 9 inch rear end i think it is a 3.00 ratio with stock tires (little 15 inch pizza cutters), and a c6. i want a c4 but all i got is a c5 which is about the same ,c6,fmx,aod and a 4 speed in the mustang. maybe i could convert it to oa roller cam that would be good.

Listen if you want this thing to run like it should, (the most bang for your $$$) then you need to forget about the cam untill for make up your mind what you want to do with motor, or build you motor put a stock cam in it and just drive it till you put the motor in the vehicles you plan to leave it in, and then change the cam. IF we sit here and tell you what to put in the motor, then you go put it in something else and it dont perform right, then you'll be walking round tellin your friends (DONT LISTEN TO THEM IDIOTS AT FTE MY MOTOR RUNS LIKE SH..!) you can build it (general pourpose) or (application specific) DW
