92-92 F350 5.0 Engine Questions

[kaw550]

I just picked up a used Jasper remanufactured engine that was in a 92 F250. I found the Jasper serial number and gave them a call to see if they can tell me more about it. I wanted to know the cam specs if it was bored and the HP/torque ratings. They told me it was out of warranty and all they could tell me was that it was factory specs for a 92-93 F350.

Anyone know the cam specs for that year? I am trying to decide if I should swap it out before I reinstall (It is going in a 72 Bronco).

I will keep looking for the HP and torque ratings but if anyon has them , please pass them along.

Thanks

Sure it's a 5.0? Afaik the 4.9, 5.8, and 7.5 were the only gas engines in a f350...

Edit: A cam for a 5.0 for a 1992 F150 would be 184i/192e at .050 and 402/419 lift.

Or something close to that.

Think a 92 should be like 195hp/265tq

I don't know the specs, but it is a roller cam.

Are you going to keep the efi on it?

Thanks. I think it was in an F250. I was surprised when Jasper said it was for a F350.

I have been stripping the parts and accessories off it for an hour or so. I am 99.9% sure it is a 5.0. Unless the 4.9 is very similar to the 5.0.

I know nothing about cams. What are the thoughts on it? I was thinking of putting in something mild while the engine is out. Is it worth it? It would be normal street driving.

Did the performance improve over the years? I also have a '68 and '87 block. I grabbed this one because it was purchased about three years ago and had the paperwork to show it only has about 15K on it. My other blocks will need more work.

I will not be doing EFI at this time. I am going to stick with the Wieland intake and Edelbrock 1405 that I had on the original engine. It's not a DD.

4.9 is an inline 6...300ci. 5.0 is a v8....302ci

cam is pretty much junk specs.. almost any aftermarket cam will be better..

what is your goals with this engine?

HP and TQ goals.. Rpms.. etc...

stock is a measley 195 hp at the crank..

 

[kaw550]

Driveabilty is the biggest goal.
If I could make noticeable gains with no real drawback I would do it. I assume for my type of driving I need torque more than HP. Although, it be nice to see HP break the 200 mark.

Would a cam have an impact with stock heads an manifolds? I have headers now but want to quiet the truck down.

 

[kaw550]

I just realized I would need a cam with roller lifter. I would be looking at $400+.

It looks like I will be sticking with the stock cam. Assuming it is not specific to EFI and can work with a carb.

 

[SuperCab]

Any computer cam will be acceptable with a carb... Not the other way around.

A stock 302 isn't a bad engine. Unless you wanna dump some money in it, I'd just run it as is. You'll probably be perfectly happy with it.

 

[5.0Flareside]

if you want to go basic put a HO mustang cam in it.. will wake it up all over the RPM band and be stronger.

you can find the cams for not much money.. and if the engine already is roller lifters you just have to buy the cam...

roller lifters are reusable for cam swaps..

and any cam will work with Carb.. lots wont with EFI..

are you wanting 200 at the crank or at the wheel? cause at the crank would only be a 5 hp upgrade.. 200 at the wheel you'll need about 45-60 hp upgrade which would be cam and port the exhaust ports..

 

[kaw550]

I am not looking for any huge gains. 5 to 10 would probably what I was looking for. Not sure what I could expect from a mild cam. I am just improvements in torque and HP over the lower end odd the power band.


I was running a '68 block and heads. The power was fine. I dont know the HP/torque of that engine but I assume it was less than the 5.0. So I will already be a step ahead.

 

[5.0Flareside]

If it was a 68-69 302 you'll probably lose power going to the new 302.. Crappier heads, crappier stock cam..

 

[kaw550]

Wow. I thought by the 90's the numbers would have gone back up.
Should I swap in my older heads? They are off of a remanufactured block so i am not sure if the seats are hardened but they workes fine

 

[5.0Flareside]

smog....


^^^
thats why the numbers didnt really go up...

 

[5.0Flareside]

depends on a few things...

whats the casting number on the heads???

 

[primetime]

68 302 4v engines were rated 230 hp (gross). The newer engine carries a net hp rating, which is generally a little more realistic.

68 302 and E7TE heads will both have 1.78"/1.45" valves. The 68 heads should have 55-58 cc chambers, whereas the E7TE heads should have 60 cc chambers. At least that`s what all my books tell me. Your 92 engine SHOULD have E7 heads, but because it is a reman, anything is possible.

Chris raises a good point about the 5.0 H.O. cam. Seems to me they are .444 lift, with about 260* advertised duration. Most dyno tests I`ve read about don`t generally see more than a few horses gain from swapping cams below the 380 hp level. From what I`ve read though, the truck guys are advancing them 2* to help the low end.

Bottom line, throw your intake on it, stab it in there, and you are not losing a thing.

I believe the 68 heads are D00E. They may actually be '69 heads.

If I am am not going to see much difference I mine as well clean up the block and reinstall. Well, after I swap all the bolt on parts.

 

[5.0Flareside]

that'd be 70 heads..

68 heads would be C8..

just clean it up, paint it. install the 92-93 engine.. and if wanted swap a cam.. that's about it..

I could be wrong, because it`s been a while and my book wasn`t returned, but I think those might be 70 351w heads, which would have 1.84"/1.54" valves, slightly bigger ports, and 60 cc chambers. Back before the small block Ford aftermarket head boom, those were the heads to have. If you can, throw a ruler or calipers on a valve and post it up, and I`ll compare to the set of 69 w heads I`ve got and let you know.

I think you may be right..
