a Hydraulic flat-tappet cam in my #F1SE (1991) roller block?

I was thinkin that I could, but now I'm kinda second guessing it....
Can anyone confirm this, so that I know what cam to order.

My motor is carburated...
1991 Block
#E7TE heads (9.0:1 cr)
Holley Street Dominator intake (single plane high rise)
650 Holley
Crane 1.6 Energizer roller rockers
Hedman 1-5/8" long tubes
Bassani 2-1/2" Stainless X- pipe (No cats)
Flowmaster 2 chamber mufflers
4 speed
3.55 traction lock

1982 GT that is gutted of everything except for the dash board, front seats, and heater/defrost, so it's pretty light.
This is my only car and I'd like to keep it streetable.
An intake swap is not out of the question either, but the car came with the old Holley intake so I left it on for now.
Maybe an RPM or RPM Air-Gap??

Any cam recommendations?
If I have to go with a roller cam, Ford Racing letter series cams are out of the question!
I'd like to go with a Comp X-treme energy split duration cam.

Thanks for all the help guys

My first question is why would you want to? But yes you can put a flat tappet cam in a 5.0 roller block.

If you must go with a Hyd Flat tappet I'd look deep into a Comp 275DEH or XE262H

That intake would be the first thing that hit the trash

A regular Performer would be better because of the limited rpm range on the heads.

I'd rethink that flat tappet cam. You will need to match the valve springs to the cam anyway you go. Putting a flat tappet cam in a roller block is like tripping over a dollar to pick up a dime. Chances are you will end up with more in it going the flat tappet route when it's all said and done.

Solid roller! But it is your daily driver so I'd stick with the hydrualic cam and lifters.

Thanks, I thought I could do that.
I must have been thinkin about using a roller cam in a non roller block...

Anyways, yeah I realize that rollers have better throttle response due to the ramp profile of the lobes and they have less friction and heat and they aid in durability...
I was just wondering if I could because some of my buddies have extra parts, etc..

I know that these heads are holding me back, but this is all I have for now. I can get a new Performer intake for free, so I'm going to go with that for now, or possibly add a 1" spacer under it to dial it in better.

My motor was a remanufactured motor and it has 23,000 miles on it, so it's nice and clean and somewhat fresh.
A company named Advanced Automotive Engineering from Canada built it. They attatched a tag with a serial # and part # so I might call them up and see if they keep record of what they build or if I get lucky they build them all the same (most likely) and can tell me exactly what was done.

When swapping in the headers this past weekend I had a good reason to remove the starter so I could see what year the block was and I was surprised to see it was a 1991 Thunderbird block. I was expecting #E2ZE,E2AE, up to 1985-1/2 cause it was a carbed motor.
The car only has 118,000 miles and it's in great shape.
It runs alot better since I removed the A/C & condenser, smog pump, power steering pump, spare tire, jack, all sound deadener, carpet, panels, etc...I removed over 250 pounds from it, maybe more.

I already came to the conclusion that I might want to look for a '79-85 4cyl 5speed to run in the bad weather, but right now I need to keep in mind that this is my only car.
I also have a '72 Grabber Maverick, with a 1970 351 Cleveland 4V, 4 speed toploader which I've had for about 10 years now, so it's my baby and it comes first.

I basically bought this '82 for somthing to mess around with, but it's quickly becoming an obsession because the aftermarket makes literally anything you can think of to make these fast. Atleast more so than for a Maverick or a Cleveland for that matter. So I'm like a kid in a candy store so to speak.

I really appreciate all of you guy's time that you take to help me out with my questions.
There's some questions in the 351 section that I wish someone would take a look at as well... but that's another subject altogether. LOL
Thanks
