Base building for 390?
So would the 390 make a good engine?
How tuff are they?
And I notice there is alot of FE engines.. What were the major changes in them? did they just change the crank to up the cubes or make bigger blocks for bigger pistons?
Any other 390/FE info would be helpful..
I currently have a 460 in another truck..But was looking for something that revs a little higher and will throw your neck back when shifting into fourth gear with a granny 4sp..
thnx alot...
I have an FE in a 73 F250 4X4 and love it. It's a 428 crank with a standard 360/390 block bored to 60 over. I used forged pistons custom cut to about 10.25 CR, 67 TBird heads with heavy port work, Hooker headers, Streetmaster intake with very heavy mods, Predator carb, port matched intake and exhaust, Crower Beast 292H cam, Pertronix ign w/coil, blocked off exhaust cross over, HV/HP oil pump with 9QT Milodon oil pan, Billit steel McLeod 428 flywheel, CF DF 12" clutch, Edlebrock alum water pump, recurved dist, etc...
I've spent about $5,000 in the engine but could have done it for less. The tranny is the NP435, and I haven't finished dialing in the carb.
the reason I tell you this is the HP is probably about 400~450 and the torque should be over 500. I don't take the engine over 5,500 RPM. Most big blocks don't rev that high without heavy mods. The FE will require heavy mods to the valve train for anything over 6000 for long periods of time.
The point is that you can build the 460 a little cheaper, and the extra cubes will help. For the kind of money you'll spend on the 390/428 you can get the Ford 514 storker kit and have mega power!
Don't get me wrong here, I love FE engines, but the 460/514 are great for 500+ HP.
Also what is the difference between the 4-bolt main 429 SCJ block and the 460 2-bolt block...can 4-bolt main caps be added to 460's..?
Grab yourself a 360 truck block (reverse 501 on the drivers side of the block instead of the usual 352). It's got extra lower end webbing virtually identical to a 428 CJ. Weighs about 80 lbs more but worth it for high RPM. A good one can be bored to 428 or converted to 390 by switching crank, rods and pistons. Email me and I'll send you a pic of my '360 GT'
