Hello,
I am wondering if anyone can help me. I am looking for the specs of the 302HO in an 89 F-150 (stock motor, Rare I've heard) in Canada. FoMoCO is pretty tight lipped about the engine, and I can't get anything out of them. I am looking to make a DD2K profile for the engine so I can futz around with it. Does anyone have a DD2K profile for it? I have searched the web, and no luck yet. is there a page of Blue Oval engine specs? I am also looking for same for a 94 300-6.
Thanks for the help,
Dave

 

What's DD2K profile? What specif info do you need?

 

DD2K is desktop dyno 2000, a popular and common engine simulator. the info I need is Bore, stroke, exact displacement, in CC, Valve size and stroke (intake and exhaust) # of valves, Compression ratio, the type of head it came with stock, the headers it came with stock, Induction flow in ***cfm @ ***inHg type format, the intake manifod type (singleplane, tunnel ram etc.), Cam type, cam specs, lifter type, valve lift(intake and exhaust), timing at stock, Indake durations, exhaust duratios, cam lobe center angle in cam degrees, cam lobe centerlines (intake and exhaust in crank degrees) and the calculated valve timing points (intake valve open in *BTDC intake valve closed in *after bottom dead center, exhaust valve open in *before bottom dead center and Exhaust valves closed in *after top dead center) Most of his information s pretty hard to find for the engine, and being a more of a 300-6 man, I don't know much about the V8's, but I want to learn, and I like knowing exactly what an engine of mine is capable of handling in the way of upgrades and mods, and what it'll change. I also want to know how much HP and torque the engine kicks out and where. Any help you can give me is appreciated. perhaps if noone has the full specs, then if everyone says what they know about it, I can piece it all together.
Take pity on me, for I am just learning,
Dave

 

Here's the basic short block numbers:

Bore:4.0
Stroke:3.0(I'll let you convert to metric)
Con rod length:5.09
Rod/stroke ratio:1.6966


89 Ho's used the E7TE heads, with overhead valves, actuated by pushrods/rocker arms, 2 valves per cylinder. head specs:
Intake valve:1.78
Exaust valve:1.46
Head flow cfm at 27 inches of water:
Intake lift: .1/55 .2/101 .3/140 .4/150 .5/164
Exaust lift: .1/42 .2/79 .3/102 .4/110 .5/114
Combustion chamber is 64cc.

Cam is a symetrical hydralic roller with, 266* advertized duration, 214* at .050, lift at the valve is .444. Lobe centers 107 intake, and 117 exuast. Average LC is 112. I don't know the intake and exaust events for the stock cam, but the symetrical B303 has 10* more duration at .050, so you may be able to extrapolate from that. The B303 exaust opens 49*BBC, and closes at 5* BTC. The intake opens 5*BTC, and closes 39* ABC. All events at .050 lift.

The intake manifold of course is a dry/long runner EFI two peice unit. You may have to use a tunnel ram model. The Throttle body was 60mm.

The HO used stainless steel shorty headers with 1 1/2 inch diameter tubes, and a dual exaust system with two pre-heaters and two cats. At the time the HO stock exaust was the lowest back pressure in the industry, beating the Corvette's, but I don't know any exact numbers on back pressure.

Stock HP rating was 225 at IIRC about 4900
Stock Tourqe rating was 300lb-ft at IIRC 3200.

 

thank you muchly
