I am in the process of rebuilting my FE390 from a F100 76, I took the block to the machine shop, it was bored 0.030". I have a recepie that I got from this site on parts for a 390 engine, here they are.

KB150 pistons
Crane cam package 343902 (includes the cam 343901 and crane lifters)
Sealed power performance Piston rings
Crane Spring & ret. kit: 270-13309-1
Edelbrock 4bbl part #1406 with electric choke (600 cfm)
Edelbrock Intake Performer RPM
Hedman Hedders HED-89100

I will keep the nonadjustable rocker arm, also, I will get new oil pump, timing chain, new valves.

Let me know what you guys think of this combination, like I said, I got it from the FE forum.

Thnak you for your help.

scratch the Edle(B)brokenSoon carb and get a Holley

 

Ought to work. Here's another combo choice that'll run on 89 octane fuel: Silvolite 1131's, and a Crane 272* Energizer cam. Your static ratio will be higher than the KB150's but the cam will allow it to run with 89.

 

Where are you all finding the build recipes? I've been searching for weeks and can't seem to find any!!!

Thanks

 

Yeah the build looks fine, but will agree with bear on the cam..But no biggy..and I dont like Ed Carbs either...it holley or it aint nothing!!

And on the builds recipes comment....Its been trial and error over the years...Ya get to know what works and what doesnt...lol

Which Holley carburator do you guys recommend, I am not a mechanic, and this is my first built. Also, what is the diference between the KB-150 and the Silvolite 1131,and also the cams.

CaptainIPSC, I did a search and that's how I found them.

Thanks

 

Ran a few different Holley carb a few times on some other engines, and seemed I was either fine tuning or removing the power valve. I could never get the Holley Carburators to Idle the way I wanted them to do.

I was happy with the Edelbrock that didn't have a power valve, which I don't have to worry about blowing and the fuel / air mixture screws adjust fine.

Not sure what Holley carb model, maybe some one will post on a good Holley.

 

I'm runnig the KB 150 with the Crane 343902, and I like the power. If you want more power go with the bigger Crane cam 343941. I've seen mentioned on this forum with good results.

baddad457 has mentioned with really good results with Silvolite 1131's, and a Crane 272* Energizer cam.

You'll find different FE engine builds that FTE members have used on different threads / posts within this forum. Some FE builds are high dollar with years of searching for specific FE parts and an ever on going search and scraping the pockets to complete their ultimate FE rebuild and other FE builds are off the shelfs with some minor modifications.

mine is kb150,crane 941, mild home porting. edelbrock rpm intake ,750 holley vacume
3.25 gears .c-6..goes like heck.likes prem gas..

 

hey, 1975 Ford: Could you be a little more specific on the ZDDP?? What is that , and why do you use it? And where do you get it?

 

The 1131 is the stock replacement for the late 60's car 390's with 10 to 1 compression. There were basically two comp ratios for car 390's then (66-70) either 9.5 to 1 or 10.5 to 1. The KB150 would be a replacement for the dished 9.5 to 1 piston. The late 60's to 76 pickup truck 390's had the stock 410 Merc pistons to lower the comp ratio down into the 8's.These pistons were also flat topped like the 10.5 to 1 pistons, but have a shorter pin height that was meant for the 410's longer stroke crank. More compression means more power and efficiency. Your recipe probably results in nearly equal results, both in HP & torque. The Crane 272* Energizer's rpm range is pretty much equal to the 343901 cam. Both cams specs are pretty close to each other, the 272 cam has a 2* narrower LSA, letting it work better with a higher static ratio. Either recipe is a good choice for a daily driver. If you can't find one set of pistons, the other just gives you more choices. The 272 cam is also priced lower, Summit sells it as a package deal with the lifters. When I bought this cam for my Merc, I chose it simply because of the cost ($125 then for the set) The fact that it worked so well with the Merc's 10.25 to 1 ratio was an unexpected benefit. That big old hunk of iron ran mid 14's with the original bore, pistons and C8AE-H heads combined with the 272 cam, a 428PI intake, Holley 3310 750 carb and FPA headers. Only other change was the swap from the stock 275 gear ratio to 3.70's. Transmission was also the original unrebuilt C-6 (car had only 62,000 miles when I sold it last year) Curb weight was 4200 lbs.

 

ZDDP (Zinc dialkyl dithio phosphate ) is the anti wear additive used in most engine oils. Some engine oils have more ZDDP, which is benefical to our older flat tappet designed engines.This ZDDP is utilized as an antiwear film between the flat tappet and cam and other high frictional contact areas in our old engines design.

The EPA (FEDS) are mandating the reduction of Zinc and Phosphorous. These phosphorous and sulfur are elements that plug up catalytic converters which increase exhaust emmission in the atmosphere and enviroment. Eventually the EPA will require zero Phosphorous levels in engine oil and fuels.

The older diesel oils (Rotella T, Chevron Delo 400, etc...) had at levels of more than 1200 ppm of Zinc and 1200 ppm Phosphorus. These deisel oils have detergents to keep our engine clean. The list of engine oils (old and new) with the zinc and phosorus in parts per million. http://www.lnengineering.com/Oilresults.pdf

The new diesel oils have lowered the Zinc (ZN) and Phosphorous (PH) with the new API rating of CJ-4.
The last time I checked the rating of some diesel oils with the API CJ-4 rating had sufficient levels of ZN and PH in their mix.

There is a bulk plant nearby where I can still get the Old Diesel oils. Diesel Engine oils with the API CH-4 and CI-4.

Therefore it is very important to add some engine break-in additive to your freshly rebuilt engine during the 30 minutes of engine running break-in period.

It is very important to run engine oils with high levels Zinc and Phosphate on our older flat tappet designed engines or a flatten cam will be the result.
