spoke with chase knight from crane cams just now .

he recommends either 1 of these

flat tappet 244 -255 with 553 and 572 lift and 114 lobe separation
roller 228 -236 with 552 and 574 with 114 lobe separation

says the roller will produce a longer power range and 30 ft lbs more of torque approx. but the flat tappet is more punchy with a smaller power band and I suppose will knock you head back quicker .
s
my only issue is the roller requires new push rods and is also 3x the price of the flat tappet. if I go with flat tappet I can use my current push rods !!!


hmmmmmm opinion's would be good ???

Chase's "flat tappet cam" recomendation is a solid flat tappet cam and is dead nuts of what I would use in this motor.
(But my choice for you is just a hair tamer choice)

His "Roller" recomendation is a Hydraulic Roller cam. Nothing wrong with that,
(" Girlie Cam")

but I was leaning to a Solid roller blower cam for your blower motor.
More power, more rpm capability.
(aprox the same .050" duration as the flat tappet solid cam .)
238 to 244 intake 246 to 255 exhaust duration @.050" 112-114LSA

I recomend a solid roller for this blower motor if you want power.
Thes motors like to rev, with a blower.
its up to you.

The solid roller cam SR "street roller" makes the most power and rpm.

the solid flat tappet cam rocks too. This is the Ford version on 114LSA of one of my Crane favorites

The Hyd roller is convenient and make good power....
It is similar to the Comp cam and your old cam but will make a hair more power than your old cam casue its a HYD roller.

The blower friendly solid flat tappet is the blower motor power/price champ by far.
requires correct cam break in.

Opinion: Calling Chase Knight at Crane Cams for a recommendation was a real good call.
I recommend everyone do this BEFORE BUYING A CAMSHAFT.

I am sticking by my two Crane cam choices, for you and your blower motor.
one is a solid flat tappet cam, the other is a solid street roller cam ( you can custom order this same cam ground on a 114 LSA if it makes you feel better. All you got to do is ask.

Just be aware of the ignition fireing order, valve train requirements, break in routine, and install details, reguardless of what you choose.
Did you ask him about the "street roller" cam core with the cast iron distributor gear added.?
Its about a $30 option. great for the street. again all you got to do is call and ask for it.

Note: On ALL FORD Engines/with any camshaft I recommend you "degree in" your new cam to ensure accurate install.
Don;t just throw it in. Ya it matters.

yep got that with the run in etc. chase talked me through the complete sequence. firing order is the same for what I have . zinc additive to be used . 1500 rpm min up to 3000rpm back and fourth for 20 mins . then dump the oil and refill with same again . said zinc is good to add


so I am nervous on the solid set up. checking valve lash a lot ? also I like the idea of the roller on the cam shaft . does a solid set up have this roller or is it like flat tappet ?

lastly if I go for his flat tappet I can use my push rods. but roller does need new ones and they aint cheap . prob to the uk with tax is 1K all in . ouch

but chase said the roller will ramp up better and provide a longer power range and provide more torque .

I wonder what the difference would be between the 3 ? not the $ cost the drive ??

he asked me every single question on my motor. was very impressed.

cheers f bird

Hyd roller is a hyd lifter with a roller wheel

Solid mechanical roller is a solid lifter with a roller wheel

Hyd flat tappet is a flat tappet lifter with a internal hyd adjustment mechanism just like HYD roller

Solid Mechanical falt tappet is a solid flat lifter with no internal hyd mechanism.

Each usings it own specific camshaft lobe design and they are not interchangable.
Do not mix and match. Each has its own specific valve spring requirements.
mechanical cams both solid and roller require periodic valve lash adjustment.
it is not hard to do, when you ahve a good method. Its about a 30minute job
1 or 2 times a year is agood for a street motor. The lash stay adjusted for a long time.
I do it "Cold".. it is easier-painless and better IMHO. Hot lashing is a pain in the ***.

I recently did a solid street roller upgrade from a hyd cam on a friends car. it now makes big power and can now rev up to where he wanted to.(Nitrous car).. Big difference... He's an *** and did not do the lash for 2 years.

it was only out by .004" on a few valves after 2 years street use . Once or twice a year lash adjustment is fine.
When you do it "Cold" (about .004" to .006" tighter than the cam card hot lash spec,) it is simple easy and just right.
EVERY TIME. Correct rocker lock nut method is essental on a Poly lock. Not that hard.

If it suddenly gets real noisey on ya something needs adjustment or came lose on ya.
That rarely happens. A solid lifter cam is more power full,a dcan and will rev higher that a Hyd cam can.
and are not a pain to keep adjusted. Or "noisey".
If your serious and want POWER and RPM this is BETTER. blower motors like to rev.

A hyd cam wether a roller HYD or flat tappet HYD has its limits. But perform well within that limit and are convienient.

A "flat tappetlifter " is not actually flat.

"The drive" Driability is avery subjective.. Thes all all "street cams The shortest duration is the "mildest"
The larger will make more power.
When you get this motor set up right ( carbs ignition etc) all these cam will respond right off idle and nail your *** to the seat as long as you keep your foot in it.
You will ahve tires sreading torque as soon as you stab it, with al these,

The larger solid cams will make more horsepower and will rev higher too.
A blower motor revs up real fast when you get on it. A solid cam ( roller or flat tappet type) by design can rev higher and not give up the ghost . 6500+rpm.

These al will idle at about the same rpm and drive real good. They are all "street cams"
but in general, if you want more power the solid and solid roller are king.
The hyd is smaller tamer and is convienent.
Are you after real power, or more of a Poser/cruiser. and never want to lift the hood. or bait your own hook.
I took into caefull consideration your car and purpose in my two Crane Cam choices for your car.
Thats muy opinion and recomendation. You are in good hands with Chase Knight and Crane Cams.
its up to you to choose. Its your car.

thanks for all the help. looked at what I wanted and the bother I had with the bad run in with the flat tappet cam. spoke in depth with chase knight last night after I read your posts. I have just got a booking for a wedding over here for next year and told chase I would like to do some weddings and commercial jobs with the car and photo shoots etc. he recommended the roller hyd cam and not to go solid as I wouldn't be racing it a lot or revving passed 6000 much . so the benefit wouldn't be huge . he did agree with you fire bird but said as its going to be a strong engine the difference that I would see in hp compared to the solid wouldnt be a big amount. I like the sound of the roller for a near 100% street car. may do a strip once or twice but not regularly.

he recommended a new hardened steel gear drive for dizzy for oil pump.

hi all .

its been a while. have now got it back and in running. just going to do a few miles in it then off to the dyno for the last tune up. f-bird. chase knights cam and roller lifters are the business. sounds so much nicer and seems more torqueyer

will post the dyno figures as soon as I get them.
I did some more machining work whilst the ending was out.

fitted pop off valve to manifold below blower
o ringed the manifold
capped off my dizzy with a piston . looks good.

video is here of first start up . idling at 930 rpm at present. 60 psi oil pressure when cold.

Been following this one for quite a while and it's great to see it running again,
SOUNDS GREAT

I truly hope your troubles are behind you and it's all about cruising from this point forward, THAT IS ONE SERIOUSLY BAD *** STANG

PS
I notice the belt walks to the front of the pulley even under low RPM, keep on eye on that...
