thinking about building up the 360 sitting in my 72 f 100, its a mild pro street project, ive been thing of putting a 600 cube crate. However if i can build up my 360 to around 300hp and may be set a blower on it was well since the truck is mostaly show with some go. Thanks

 

its not too tough to get 300 ponies out of 360 cid.
a necessity is an aluminum intake and a carefully selected cam.
a good swap is for the 390 crankshaft,rods,pistons but not necessary. you will have to boost your compression with decent pistons. if you do want to run a blower it'd be good to stay with a 8.5 or so to 1 compression to be safe since its not a race motor. 300 horse will come no problem....and a blower should give you in the 'hood of 600+ hp on pump fuel

 

390GT What kind of torque will the 300 to 600 horses give him?
What I'm curious about is the duration of the Torque curve of all that HP against the curve of a Diesel?

 

The torque curve runs about 2000 to 4500 and is pretty flat on most builds, I think the Lobe Seperation of the cam is the big factor here.

Here's a post from someone elses setup:

Stock eliminator motor, 4.090 bore, stock stroke, factory style pistons, my ring combo, stock lift hyd.481/490 lift camshaft, johnson lifter, C6AE-R heads unported with stock size valves combustion chanbers measure 68 cc's (63 being the min)factory intake and Holley carb unmodified with 67/77 jets. A pretty basic piece. It made 456HP and 470 lbs of torque. Super Flow dyno that is a consevative piece.

We do run a filled block and our cam only has to measure stock lift, any duration and overlap. Runs 11.20's @ 115mph in a 67 Fairlane that weighs a little under 3500 lbs, 60 fts 1.47 to 1.51 depending on track and weather. And best of all its a bulletproof piece.

 

Karl, I know that you are just reposting somebody's prior post, but this kind of HP and torque from a VERY mildly modified stock engine. I'm whistling on this one.

Back to the original question, 300 HP is fairly easily achieved, even on a budget. The first thing you need to do is add a 390 crank, rods and possibly pistons (many 360's actually had 390 pistons from the factory). This alone will get you 40 HP. Next add a mild cam, 4 bbl intake and a 650 cfm carb, free flowing dual exhaust and I guarantee you'll easily be over 300 HP. Of course you can continue with more mods but expect to have your wallet ready.

About this guy's built 360!

I didn't actually get my calculator out, but it seems like he'd have a delicate problem about 800 to 1000 feet down the track.
To shift or not to shift?

He's already shifted once! He's close the top of the Touque curve, about 4500 Rpm. He's in his 2nd gear, very close to the line. The engine will only increase RPM to 5500 or so....

Should he go ahead and run for the line? Running the R's up very high, beyond the Torque curve, risking the engine, or take the time to shift and hope the Rpm's will stay up high in the Troque curve?

AHHHH how nice it is! So much fun to have such choices. Memories....

I was wondering if a 300 horse 360 would sustain a long haul (up I-25 from New Mexico to Colorado) pulling a 7000# RV (With the wind in your left front quarter)? A Diesel has trouble with that pull, but has such a wide torque curve that it keeps pulling throughout most of its Rpm range. You dont get stretchd valves and such with the Diesel either.
Fuel usage under a pull would be another question.

So whaddya think, Should I run my 460 up to 502, build that up to 600 HP???? I could pull the 5er with that!

Thud

I'd opt for the stock 390 over the built 360, better rods, more effienct... The FE's will handle runs up to about 5,500 without trouble, it's when you go higher than that things change. I'd opt to shift, with such a low torque curve I'd feel safe.

I considered the 460 with a Motorsport stroker kit, I'd like to try one out someday.

 

Me too!

 

thanks for the responce, i think ill just fix up this engine since the motor is in great shape with low miles and sounds good and drives great. Plus with the savings over the crate motor i can add a blower. If possable does any one make a blower manafold for the 360 or by changing the heads will that automaticly set me up for off the shelf blower, any help would be great trying to get the truck ready for pidgon forge in may

 

Hampton Blowers has complete FE kits for 3000

 

how much torque/hp do the 360's put out?

My friend has a 71 f-100 w/ a 360 in it..nice truck..

thanks for the help, do they have a site.. Thanks again

 

dixie, yeah they do, check your post in the FE forum and BBB posted the website http://www.hamptonblowers.com/price.html but you need to know that it's not cheap, you will need to rebuild the engine to run it, with 390 forged flattop pistons (390 flattops give 8:1 in a 360) and you need 390 rods with good ARP bolts for the rods and preferably main studs at a minimum. Another thing that would be a good idea is to get a 361 FT crank and have the snout machined down to fit FE parts on it. You'll need to upgrade your cooling system too, and dont expect this thing to fit under the hood if you want a roots type blower. Vortech is making a kit for carburetors on Big block chevy's and this will probably be adaptable to any engine given enough money, it will also probably be more expensive than the roots type.

Geoff, I believe it's somewhere around 215 hp

 

yes i plan to rebuild the engine before the blower, and the truck is a pro street to i can live the look. I checked out the site and found the price better than i thought i was planing on spending 7000.00 on just a crate motor and now with modifing this 360 i have and the blower im still saving 2000.00 Thanks for the help
