x cam

i would recomend the f-cam if your looking more for performance rather than gas mileage and drive ability if you have an auto you might have to get a stall converter but the f-cam is for more of high rpm horsepower you might also have to worry about piston to valve clearence with its .512 lift but any of the ford racing cams make good horsepower i think you would be pleased with it if its just going to be a street car you might also want to look into the e-303 its a good cam for street use and has better drive ability has no valve overlap (better gas mileage) and makes good horse power and would go good with your edelbrock intake.

i wanted the comp XE270HR cam its similar to the F303 but has different duration. but i found a good deal on the F303 so i just went with that. the comp cam is like $260. im satisfied with my F303 cam but then again i havent had anything else besides stock. power kicks in around 3k and when i shift it right in range of the power. if you have the F303 cam just throw it in but you will need to upgrade the springs regardless of what cam you use.
i didnt have any ptv issues with the .512 lift. just stay with the 1.6 rockers so you dont add any more
and the drive ability is just fine. it drives just like stock did just makes a lopey idle

Ok the X cam is out, since I'm going to need to fly cut the pistons...so now im down between the B or F cam... i know the B is for low end torque and it says high rpm hp...and the F for mid-top rang. Which cam (between the B & f cam) would better match my edelbrock rpm manifold??
In any case I put stock e7's with the stock valvetrain in, but left the cam alone & had no issue in over 3 years of daily driving/occasional race. I definitely wouldn't recommend doing it though. The only reason I never did was because I intended on buying aftermarket heads shortly after & didn't want to waste money to turn around & have to buy something else, now I have too many project cars that I have money wrapped up in so I never get around to it.
For the record, the letter cams (& all single pattern) aren't too friendly with stockish heads. You'd still get a little more power, but they're a bad choice due to the horrible flowing exhaust. I got my x cam with the intent of buying some aftermarket heads, if I would have known that I would have been wrapped up in other projects I would have went with a dual pattern over the letter. & I definitely agree with mjr, if at all possible upgrade the valvetrain when you swap the cam... otherwise I'd say hold off on putting the cam in until you can.

I would use 1.6 rockers, and a definitely check your piston to valve clearance. The trickflow tech said if it is a little to close just retard the cam 4*.
Ill be pulling apart my car at the end of the month, have it back up and running early next year. Ask me then.

god you take forever!!
i have no room to talk. i have mine all back together, ever since the head came back fixed, except the plenum and intake tube. i stopped working cause ihave having severe back pain...turns out my liver wasnt functioning lol

no real great weather until around February.
plus i wanna take my time and do a ton of little things the car needs. Just got my heads and intake back from my engine builder who port matched the intake, and ported the lower a bit. Time to start ordering parts off my wishlist.
Also going to pull the block, check the bearings, and clean up the engine bay just a bit. No hole filling or wire hiding is planed, but some of that could happen depending how this winter goes.
you might wanna go see a few doctor's about that liver man. Or just stop drinking like a fish scene you got the baby news
