Default 1985 5.0 H.O. engine specs and information

can anyone tell me the specs and info for a 85 mustang with a 302 H.O. motor. i need as much as i can get. cam type, timing, idle rpm, etc. or tell me where online i can find things. i googled it and found little. any info would be muchly appreiciated. i think its time i work on and possable mod my stang but i need to know where to start. so far i just added a holly 4160 carb to a rather stock stang. next a good clutch. when i had it done last the guy said it had a clutch from an 95. should i go back to stock 10 inch? what mods sould i consider? i am thinking a new cam. have the rotating assembly done and the top end sealed. i think it is leaking. it idles around 1200 or so rpm. the bolts i could reach with carb on were not snug. what yall think i can do?

for good info, check out the tech section at jason.fletcher.net . and since i don't think he has head specs posted, here they are: stock "E7" heads have 58cc chambers with 1.78 intake/ 1.45 exhaust valves and 124cc intake runners. don't go back to the 10" clutch, the 95 clutch is far better. don't bother doing a new cam first thing, the stock one is pretty good. full exhaust mods should come first, fooled by a new intake like a weiand stealth and then a good set of aftermarket heads. oh, a full tune up would actually be the best place to start if you haven't done that yet.

The 1985 H.O. engine had 8.3:1 compression, 210 hp at 4400 rpm, and a 585 cfm Holley 4180 carb. Have to check on the cam specs, no ever asks for that. But it was a hydraulic roller cam, I don't believe it was the same one used from 87-95.

Cool

I was wandering, can you put aftermarket heads on an 84-85 h.o. Or are the pistons the same as the 86 which i think you can't?

And what would be the better heads to use with these pistons?
