need a cam for my 351

stang94X · Jun 22, 2009

a while back i was planning on a 408 + stroker cause i could get the internals for a good price but i found a set of forged pistons and eagle h-beam rods for a 30 over 351 for a hell of a deal i couldnt pass up, now im looking for a cam that would work well with it, i would get a custom grind but im too damn cheap to spend the extra amount for one, so i just like to get some opinions on a good off the shelf cam that will work well with the set up, im keeping the stock roller set-up from the 5.0, the same heads and 1.72 rockers i already have, the compression is going to be 8.6:1 or so and the motor is going to be boosted pretty well, according to pulley sizes it says the psi will be around 16-17, but i wont know actual psi untill its running, the valve springs in the heads now can handle up to .550, i can get new springs if needed, id like to have a cam with a strong duration and higher lift if it would work well with boost, thanks

Comp Cams 280H

stang94X · Jun 23, 2009

do you know what the specs are on it and if its a roller or flat tappet, i need a hydraulic roller cause im keeping the roller set-up from the 5.0

uncltrvlnmatt · Jun 23, 2009

This is a hydraulic cam for the 289-302-351. It is used with flat tappets not roller. Specs are 280 duration .515 lift. Comp Cams probably hasan equivelant for roller tappets.

I ran a Comp Cams 270H in my 289. It was a 270 duration .500 lift and was awesome. The RPM range was 1800-4800 if I remember correctly. It has been a while.

I would call Comp Cams, Crane Cams or Anderson Ford Motorsport and ask what to run.

This the most vague post ever. Your heads, intake, displacement, compression, as well as setup for the car dictate what type of camshaft you should use. You will not be happy with some random cam unless all you want is idle quality.

You won't get idle quality with this cam. It is going to lope like a SOB.

i stated that its a 351 with 8.6:1 or so, maybe 8.8:1; i cant remember, will have the same heads and rockers that i already have, the ported gt40x with 1.72 rr, and will have a good amount of boost

the intake is the victor 5.0, the heads are being ported more on the exhaust side and matched to 1 3/4 headers, everything else is staying the same beside the aode tranny is being built to handle power and the fuel injectors are being swap from 30# to whatever i need; i dont know which ones yet

i just need a well working cam for the street that will make power; and is good with boost

I had a Lunati 51015 in my old 418. It was an extremely mild cam with excellent idle quality and great manners. I just tapped the black and installed OEM Ford lifters/retainers/dogbone. The cam was way too small for my 418, but it would work reasonably well in a mild 351 - and of course, everything works better with boost.

I have seen a lot of similar combos making good numbers using the Anderson B451 camshaft. Howver, for the price of the Anderson cams, you could easily purchase a custom job from one of the top camshaft guys. Do not expect to spend only the cost of the camshaft either. Chances are good that you will need new springs for your heads to match the ramp rates of the camshaft and the RPM's you intend to turn. If you have aftermarket heads with healthy springs, you could easily share those specs with the camshaft designer and he could develop a cam that will work with your existing springs and give great performance based on your criteria. To me, that is a savings opportunity that is worthwhile investigating. Hope this helps!!

you remember the specs on that cam, i tried searching it and even went onto lunatis' web site and had no results

Paul · Jun 24, 2009

Oops, look like it is 51017, not 51015.

Specs are: .536/.536, 218/228 @ .050, 112 LSA, 108 IC

Valve events are: 1 BTC, 37 ABC, 50 BBC, 2 BTC

It's actually a nitrous grind, but it kicked ass my in street car. 442 ft. lbs. of torque naturally aspirated with STOCK exhaust on a 418. LOL :grin:

stang94X · Jun 25, 2009

im assuming that lift is with 1.6 rockers, with my 1.72's the lift would be around .576, would that be too much for a blown small block, everything looks good for a street motor, i just dont know what lift is too high or too small for a blown application, the duration of it is about what i want for streetability, but a little higher wouldnt be bad, as for the 112 LSA; i was told to try to get around 110 or is 112 more optimal

Paul · Jun 25, 2009

I'm not a camshaft expert by any means, but I'll do my best.

Wider LSAs (e.g. 112-114) will typically have better drivability and manners. This cam definitely has pretty mild duration, but it literally idled like stock on my 418. If you want a cam that is perfectly suited for your combo, get a custom grind.

Do you have a blower already?

stang94X · Jun 25, 2009

yeah for a $350 cam im better off just getting a custom grind...lol

yeah i have two blowers, one powerdyne that was cleaned up and had 928 motorsport bearings and belt put in, numerically set-up with the crank and supercharger pulley to make 13 psi, and have a vortech v2sq kit that wont work cause its for a 4.6 but i knew that before i got it but plan on selling it and getting one that will fit but i have a pulley for it thats numerically set-up for 16-17 psi

Trick flow stage 2

mikey94gt · Jun 25, 2009

ive found the TFS stage two is kinda small for a decently built 351W. Like I said, I would call the big 3 cam manufacturers and ask them what cam, lifter, pushrod, rocker and spring to run. That is what I always do.

stang94X · Jun 25, 2009

^ i probably will, i just like to have personal opinions on that people have actually used before i start talking to a tech guy reading off a data sheet
