Depends how that 390 is built.390's much easier/cheaper to get than a 428 and w/the new Edelbrock heads is a great performer.Remember,there were HIPO 390s before 428s showed up.Having said that,if you're gonna cut up a car for a bb ford,do the 385 series(429-460)instead.Cheaper,more powerful and able to stroke up to 514 easily.Parts much more plentiful than FE(390-428)stuff too.
Au' contraire, my Texas buddy. The 390 is not a truck engine. The 390 was the hot rod engine of choice for most 63-67 Ford buyers. The 330 HP Hi-Po 390 was a torque monster and could spin up to about 5500 rpm (or higher). The versions for automatic trannys was 315 HP and had a hydraulic cam. The one for manul transmissions was 330 HP and had a solid lifter cam. A stock 390 with the Edelbrock power package is as strong as the 428 that was put in your 7 Litre cars of the mid-'60s. A 390 with 428 crank is a 410 and produces even more torque. Now, the 360 (same block as the 390/406/427/428) was a truck motor and was had no high range horsepower. It was made for granny gears. Ford also made a 391 based on the same block that was put in 1 1/2 ton and bigger trucks. The Mustang used in the movie "Bullitt," was a 390 that had shaved heads and a few other mods - to er, uh, make it keep up the 440 Charger.
I have access to a 6.1L dump truck engine, which I think is 390...It is free, and runs, the trans is toast. I never messed with it thinking it was a low rpm, high torque motor made to function as a hauling motor, not a speed application. If I would have known it was worth a crap, I would have spent some of my money putting in a MII front suspension and rebuilding this 6.1... It just seems like way too wide and heavy a motor to drop in the mav.
The 6.1 is a 370 engine. It was used in big trucks. I'm not 100%, but I believe it was used in '85 - '90 big trucks. It may be a 385 series block (460), but I'll need to Google to make sure. I Googled: http://en.wikipedia.org/wiki/Ford_385_engine
Hedman and Hooker both, listed FE swap headers for the Mav until just recently. I have seen them and you can tell they were made to work with shock towers. I was told the FE will fit with just a shave, rather than a complete M2. The swap headers have been in the books since the 70s... I read some old literature that said the 361 and 391 FE truck engines had steel cranks. The rodders used to take them for use in 390s, 406s (or was it 410s?), and 427s. They also used some serious rods... The 370 is a low displacement truck 385 series. All the weight of a 460, but not many more cubes than a 351.
Man, you got that right. My '71 F250 had a 360 2V/C6 with 4.11 rear gears. That thing couldn't get out of it's own way and got 6-8 mpg and topped out at about 55 mph. Then it lost oil pressure one day and put itself out of it's misery in a big white cloud of smoke. Judgeing by the rediculously beefy trailer hitch on that truck, someone used it for towing some very heavy stuff.
Jamie, I cannot quite tell what the pictures are of...is that the oil pan with the idler arm in the top left? I can tell it looks BAD, but I just can't quite see exactly what it is...
That's the drivers side of the block, looking up from underneath the truck. Happened a few years ago when I was cruiseing down the road in my '71 F250. The connecting rod broke and went through the side of the block.
There's a mechanical term for that... Its called "Negative Internal Crankcase Evacuation", or NICE for short...:evilsmile
the 6.1l truck engine is a 391 actually it has a forged steel crank in it as it's only saving grace.. I'll let your imagination run with it as for what I would do.. 351 + stroker = 427 = your choice
I don't think 6.1 litre adds up my dads 1967 390 Cougar has 6.5 litre emblems on it.So I'm pretty sure a 6.1 is a 370 inch 385 [lima] series engine Heres the Cougar fender emblems.Derek.
The 391/361 truck FEs do have steel cranks,but the snout has to be machined down to fit in a car/light truck block.Those blocks are are so deep skirted,the cast cranks usually last well anyway.
(checks math.. and smacks forehead) DOHHH 61 cubes per litre 6 litre = 366 7 litre = 427... duly noted
