Is this possible on a 1977 Ford Truck with the good 351 Ci V8..?

Question

..to achieve 400 HP with shortened piston heads (for a longer stroke), bored out cylenders, excellent carb, dual exhausts, high flow cat converters (if any), high flow fuel pump and fuel filter, spark plugs and ignition, better headers, and a high flow air filter (it used good grade oil and maybe a few other modifications)?


Yes, Im asking again, because of those stupid no good for nothings who answered my last question

Answer 1

yes it is very possible also change the cam good carb and the modifications you are doing you will get it and maybe some more

Answer 2

Ok let me simplify this,personally i am a chevy man.You can get 400+ HP with no block modifications at all,a good set of edelbrock alum.heads,mild cam,speed demon carb(Made by Barry Grant)and a mild performance intake,hooker super comp. Hedders.and a quality ignition system (MSD or MALLORY)and a heavy duty fuel pump will do the trick plus some..Yes you can mildly stoke a motor without block mods. But my theory is if your going to do it ,do it BIG.. You dont want high compression because you cant run regular fuel any more the highest i would go to run pump gas is 10.0:1 ratio...A bit of advice 400 HP is not much for a truck that size...This is just some advice..the right top end set up is the key to power ..yes you do need a good solid block as a foundation to work with but for a fairly mild street engine that wont be turning high RPM and wont be on nitrous i would reccomend staying out the block...For example i have a 91 chevy S-10 with a 350 block bored and stroked to 427 cubic inches i had to have the block cut so the crank wouldnt hit the sides and oil pan special made the H-beam rods had to be percision ground so they wouldnt hit the cam the stroke is an even 4.00 inches a LOT more than stock the pistons are 10.15:1 forged JE with a 15 cc dish to keep the compression down ...Alum. AFR heads (air flow research) RPM air gap intake with a 850 cfm demon carb,MSD pro billet dist. with MSD digital 7 ignition box plus 700+ HP nitrous 2 stage fogger system Just the motor puts out 600+ HP and 600+ ftlbs of torque YOU DONT WANT TO KNOW WHAT JUST MY MOTOR COST.....

Answer 3

Well first you must decide how you want your 400 horsepower delivered? where do you want your power curve basically??
Anything is possible, especially with that much displacement..
Definitely harder with the Ford than with the chevy but still possilbe.
www.summitracing.com is a good source of parts and tech knowledge as well.

I personally, and I sold my 351 years ago, would start by blueprinting the entire engine. get it back up to spec and see if your block can handle the machine work necessary to get it back in the game.
then, plan your attack building a naturally aspirated motor is completely different from building a forced induction motor, I highly recommend forced induction if you want to hit 400hp. by the way.
Start with the block, more displacement is better, if you can afford better pistons get them, same with crankshaft, and rods.
Spend as much money as you can on your valvetrain and your heads as that is where you will get your major numbers from!!
aluminum high flow heads are a must!! as is a properly tuned exhaust system. spend a couple hundred bucks at a dyno and try different timing and exhaust combinations. Catalytic convertors really don't hurt horsepower as much as urban legends say they do.
anyway, tuning is the most important thing you can do following flow.
An engine is basically an air pump so just keep that mentality, blueprint, tune, modify,test, modify and tune some more. 400 horsepower is a very reasonable goal with a motor of that size just make sure you're budget gets spent in the right areas.

oh and one last thing, don't ever trust a machine shop, remeasure absolutely everything they do!!! trust me on this..

Answer 4

Actually if I were you I'd go for dome op pistons that will give you more compression Have the heads gone through for a valve job and while their at it what is the cost for drilling out he old seats to put in bigger valves Also have the heads"shaved" about .30 thousandsth . Start buying mags like HoTRod or some other mag that tests products and engine upgrades. A lot of high perf. manufactures advertise using their cam with with certain intakes and certain carbs will give you an honest 400hp+ Use Castrol 5w30 breaking it in and then go to 10w40 in the summer. Everything else you mention sounded good. Everything I mention is an economical . By the way, yo didn't say what you were putting the Mill in?

Answer 5

yes you can get what you want from a 351,,i own a repair and restoration shop,,and i have built a ton of ford engines,,you have the right idea,s to do it with,,you,ll need to increase the fuel line size from the tank to at least a 3/8,,line,,to get enough gas flow to it,,other wise you have a pretty good combination there,,but don't go over board with the cam,,get a low rpm to mid range performance cam for it,,with a good lift,,and it will literally scream ,,i have a ford torino with a 351 in it,,and it runs 438 horse power at the rear wheel,,and it is just a little above stock,,good luck with it,,i hope this help,s.

Answer 6

ok, i dont like ford, but yes, this is very possable, with all the things you mentioned you might even get around 450hp or more, depends on alot of things, like what brands they are and how long of a stroke your going to and I would suggest going with true duals, more power but it sounds worse when something is wrong, lol

the older the ford the better, I used to have a 79 ford 4speed with a 351, it was only a farm truck, but it never burned or leaked any oil for the five years i had it... a good ford is hard to find, i hope you got one if your going to get 400hp out of it.. good luck

Answer 7

Do what my dad did. He stroked his 351 windsor to a 408. Then bought the Roush 200 cylinder heads and edelbrock victor jr. intake and edelbrock carburator. Which I recomend a Demon carb he has been having problems with his edelbrock. Then buy a Vodoo Camshaft from summit racing. Thats pushing over 400 hp and use ARP main studs and cylinder head studs. Recomend it highly.

Answer 8

The 351W is largely a 302/ 5.0 block with a taller deck top. The cylinder heads are .5 inches farther removed from the crankshaft, and because this is a V block, the heads are additionally farther aside from one yet another than a 302/ 5.0. you won't have adequate space between the engine and sweetness tower for exhaust manifolds, till you employ a restrictive forged iron head.

Answer 9

Yes its possible

The 351 is a good engine and with a little money and time its possible

Answer 10

Hello, yes it is, I would recommend to stroke it to 427, you can fins a stroke kit at Ebay Motors.
Actually we are building a 77 one with a 460 engine, stroked to 547; how does it sound???.
