im pulling my motor here in the next few days to freshen it up with new gaskets, seals, etc.
along with a cam/lifter swap.
the motor is a FE, i was told its a 390, but i think its a 352.
right now its all stock with a eddy intake and carb.
i plan on going thru it and installing new seals and gaskets, valve job and some aftermarket stuff.
im gunna get a comp "mutha thumpa" cam and lifters, will i need adjustable roller rockers for this cam? will 1.76 rockers work?
would i need springs too?

FYI, 352 was cast into almost all FE blocks, so don't base your assumption on what's cast in the lifter valley or by the casting number. You need to measure everything to see what you really have.

make sure on the rear main seal that you put a dab of silicone on the 2 halfs where they meet.

Since the FE motors are shaft mounted rockers, I think almost all rockers have adjustment screws on them so you can set the lash correctly.
As for the rocker ratio, stock is 1.73, so bumping to 1.76 is almost nothing in terms of extra lift. I don't think there is really anything on the market other than the 1.73 and 1.76, because being a shaft mounted rocker, you don't have the adjustability you need to be able to change the rocker angles on a different ratio rocker.

only half of the 428 and and all the the 427 had adjustable shaft rockers. and he was warning u about the real silicon trick cause the fe motors have a weird and rare drop in rear main cap. u built motors before is cool. but have u built a fe? beside those things and a couple other things there kinda by them selves in trade tricks.

oh ok, would i need adjustable rockers with a aftermarket cam?
and ive never done a fe, but ive been reading up on them alittle and read about sealing the rear cap.

if u dont know what they rate, have them checked. if its a performance cam i always just get new springs that match. 1o old 40 old springs that where set up for a stock cam well never be nice with a new hipo one.

look into building a 410 with it. i built three of those 390 about seven or eight years ago and was never that happy with them after. then i pulled one back out and built a 410 with guidance from a old factory sponsored drag racer from the early 60s. what a difference! he told me the 390 was designed as a truck motor and will always behave like one. if i remember right to make the 410 it was a 390 bore with a 428 crank. not for sure its been along time but look into it. i remember using the same cam and heads that were on the 390 and i ended up with the same compression ratio as before too. but that 410 was night and day difference for a car. and yea 415 is too high of seat pressure. we shoot for 575 lbs on the funny car i work with. but thats holding back 50lbs of boost and 8000 horsepower. your prob going to be somewhere in the 120 lbs range. those eddy heads shold be in the ball park, maybe just a few lbs off if anything.

having second thoughts now.. hopefully this is a 390 and not a 352.
if its a 352 it would be more to get hardened seats and work done to these heads then brand new aluminum heads would be for a 390..
the $$$ just keeps adding up for this FE.
anyone got a 390 shortblock laying around? lol

dont worry about the rockers ither, id just run the stock shaft rockers and get the correct length pushrods for the job. factory adjustables are nice but you dont gain much in the performance end, and if you have the wrong length pushrods all together than you will need them anyway to keep the valve geometry correct. if i remember right roller rockers are rediclious on price for em, and shaft mounted rockers have very little friction naturally. they also are the most stable setup you can get by far. i ran the eddy heads on two motors and they were great, the other motor had reworked 69 gt heads and that thing wanted to detonate with so little timing. i think they just make too much heat for todays shitty fuel and the cast iron wont keep the combustion temprature down because of it.

The bad part about building FE's now a days is all the rampant miss information and I see lots of it already being quoted to you... Look up Fordfe.com lots of FE only die hards there with no kids posting dumb crap, lots of old knowledgeable guys on there along with Bobby Spears who is a 60's factory backed Ford racer who will also be running his original factory light weight 64 Galaxie today at Kingdon and is an Oakley resident. The 410 is an Awsome motor but very hard to get all the parts for and when you do get the parts its equal to a 427/428 I've done the reasearch for it. If your serious about building power for it look up Survival motor sports and talk to Barry Robotnic, another hard core FE guy (also an feford.com member)from Michigan who has won the engine masters challenge more than once using an FE. he has a rotating assembly that will turn your 390 (real 352's are rare to find) into a very very healthy 445 for only about 2500. (Look up survival motorsports on you tube he has lots of vids of his different build and has a good book called "Building Performance FE's there two copys at Barnes and noble on lone tree")If you want Pm me I'm the one from Antioch building the 390 for my 68 Cougar and ill be assembling the the rotating assembly tonight in stockton.

the Comp "mutha thumpa"
Ive used that cam twice. Once in a 351 and once in a mopar 383 big block. Noisy cam, shit vacuum which makes the carb hard as hell to tune but sound like animals.
Both of those motors had aftermarket aluminum heads with some serious valve springs.
Long term with 4 something on the nose your valve seats wont live long.
Hop on over to FE websites and go with what the guys that are putting down numbers actually use. Kinda like use small block guys over here...use shit that REALLY works ya know?
Dan
Here is a budget build that runs pretty good in this guys 66 F100
Balanced 390 .060 over, Comp 270s, gasket matched F427 intake, headers, gasket matched/bowl blended C8AE-H heads
And 445 engines fuckin haul the mail!!
This one made EXCELLENT power and hey look its the 3310 carby I recommended......whatdya know...

I agree with Dan, I was gonna use a thumper sounded awesome.... Turns out its a "show car" cam for cheeves to idle around car shows and pose with LOL . I've got a 270h comp going in mine. Don't forget that with our Dino lube motors we need lots of zddp not that oil companies have been removing it we are losing a lot of cams lately (you can read about it at feford.com) an author named Steve Christ wrote a good book on FE rebuilds called "How to rebuild Big Block Fords" its a great basic book but some of his parts data/facts is wrong.

i have that 410 in my 67 mustang lol,. and that thumper cam is way big or anything close to it. anything that big isnt just a lil upgrade needed. dp mandatory unlike the discussion before of recommended carbs.check what u have first so your not wasting time. then check your budget, plan.
