Another engine question, 351w H.O!!!

68MustangCoupe · 07-26-2009, 02:27 AM

Ok, I know by now you all are probably getting tired of my asking about different engines, but I really haven't decided on one. And I only ask when I can't find answers through my own research... *Unless it's wiring then I'll just blatintly ask*

Ok... So The 351W H.O. out of an 85-87 give or take Ford truck I've come to understand has like 210 HP and about 330 TQ...

I'm pretty bent on the T-5 Because of the 5-speed and the non-expensiveness of it. The TQ is Good. What I'm curious is if there is anyway to increase HP rating, without touching the Tq or at the very least keep it with in 10-20 pounds of the 330 mark...

Thanks for helping me with my constant questions! You guys are Helpful!

the heads on the 351 should be E5 or E7 cheapest way to pick up a few more HP is gonna be to go with gt40 heads(explorer,mountaineer,lightning,cobra all had them)

why are you trying to not go over 330tq?? sticky tires and a stock shifter will kill a t5 faster than anything

Because everyone is always saying torque will kill the T5. And supposed rated for "330" Torque which the H.O. is supposed to have stock... And I'm not gonna lie, I'm probably going to want to Romp on it and I don't want to to blow if the Torque is higher then it should be... As for tires, It's not gonna be a track car, it's Gonna be a street car. No Sticky tires but I do want to put fatties on the back as I see this as one of the "Muscle" looks that I love, So I figured If I kept torque down it wouldn't pose much of a problem.

run the t5 till it grenades they are a dime a dozen :P

a lot of guys even drag race v8s with the 4banger t5s and run 11's :P

So basically what your saying is get the Real 351W an aftermarket shifter and go to town? *By real I mean the 60s-70s*

rmodel65 · 07-26-2009, 03:39 AM

if i was gonna get any 351w id buy a 94+ roller cammed motor(also one piece rear main seal) out of a truck/vaan and add head a cam and intake.

there no reason to get an old block, you can find a low mileage 351 in a junkyard. you will have to get a flywheel compatible with the t5 and 28oz balance and a distributor compatible with the roller cam and oil pan etc but other than that its all the same :P

So I would basically have to put everything from an older 351 on the newer 351?

Did you know that torque and HP are always the same at 5250 RPM?

Horsepower is actually a derivitive of torque.

In simple terms, torque is raw twisting force,

HP is twisting force X Speed, expressed in such a way for us to visualise how much work can be done and HOW FAST...

1 hp is supposed to be the ability to raise 33,000 lbs 1 foot in one minuite.

The short answer to your question is that yes, it is possible to raise HP and lower torque at the same time, (by more or less raising the RPM operating range of the engine) but it really is not all that practical with an old school V-8 like the 351. Works better with rice...

But, all else being equal, I like rmodels advise best anyway, run it, when it breaks replace it...

Alright, so be it... I've decided. I'm getting a 351W with the T-5...probably many t-5s. burn outs, power stalls, Maybe I'll get a cam that will move the torque from low end to mid-range, that why there's not a lot of low end torque so burn outs and what not won't hurt as bad, and I will still have better passing power *Or take off power at speeds* around 3K... Theoretically.

AND, I've already decided what I want to do with My 302! *Evil maniacal laughter* And when people ask why... I shall simply say, Because I CAN! Ok, done with the evil laughter now.
