1986 5.0 Mods
 

What heads, if any, can I bolt onto a 1986 5.0HO without piston to valve clearance issues? Can I bolt on 1.6RRs? Would I see any gains with an aftermarket intake, or would the cylinder heads be holding me back?

I'm getting power hungry and need ideas.

BTW--Current mods--Explorer 65mmTB, K&N Filter-removed air silencer, Timing at 16*, Magnaflow mufflers--hogged out cats, and a BM fan later this week. 3.27or3.55 gears coming this spring.


Thanks,

Your on the right track with your mods now that you got more air coming into your engine you might want a better intake, I have Trick Flow street heat upper and lower intake which flows, as for heads theres a wide market out there right now I think AFR 185's and Edelbrock heads are whats hot along with some MAC or BBK long tubes or shorty headers to get all that air out. I think the 1.6 would be fine with mild heads and a stock or mild cam. Hope I could help


I have a set of gt40ps on www.ebay.com along with some headers

In 86 the pistons didnt have valve reliefs. I have heard that the Trickflow twisted wedge heads will work on an 86 cause they dont line up with the stock valve reliefs anyways.

I'll have to look into that.

I love everything about this car except for the lack of valve reliefs.......

Yup, TFS Twisted Wedges will work, as long as you don't go too big on the cam. Use a set of 1.6 RRs, and a good intake and you'll love it. I don't think anything bigger than the E-303 or the Stage 1 cam would work.

What ratio rockers does my car come with stock?

Would a mass air conversion be neccessary to realize the full potential of a head/intake/cam/rocker swap?

Sorry for all the questions, I like to do my research well ahead of time.....less surprises once I get the project underway.

Thanks again.

A mass air converson would not be necessary but I would highly reccomend it.

mass air?
 

why is it important to convert? mine is still speed desity .... am i missing something here?

I was running speed density up untill a couple of months ago so I know you can run speed density with alot of mods even superchargers.

But there is no doubt that mass air is way easier to tune.

ahhh
 

ok;)

86 block is a Mexican block I believe. No coolant passages between the cyl walls. Means you can bore .040 over w/out problems. I have another 86 block you can buy or if you really dont want valve reliefs I also have an 89 block with stock ported heads, B-303 cam and 1.7 rockers.

If you wanna pick up some power for cheap, grab a 87+ intake and a set of stock E7TE heads from a 87+ stang or truck and give them a light port job yourself.

How did your 289 turn into a 306:cool:

Get rid of the 86 heads for shure. From what I remember they where the most restrictive ones.

Mexican block

comatose , black 85 gt
if those are your cars ,, nice four eye;)

nice four eye? Huh?

four eye
 

'83-'86 Mustangs had four headlights...two on each side. Actually they may have began before '83...might go back as far as '79.

The 79'-86' have four headlights, 87-93 have two w/ the aero look.

Oh ok, I know them as square light.
