I have an 86 5.0 motor that i'm going to put in my mustang ii. I was wondering if someone could give me an estimate on it's hp. here's what i know:

bored .30 over
torker 289 intake
edelbrock 600cfm
HEI style distributor
Fox shorty headers or blackjacks

thanks

 

Somewhere around 235-250 at the flywheel. You will need to get it dynoed to be sure.

 

cool, this summer i plan on getting at least 300-320 out of it. What should i do next?

 

cam i'd say

 

heads/cam, long tube headers.

 

EOC is dead on. It's amazing what putting some aluminum after market heads like AFR 185's will do to wake up that engine. Top that off with a good cam and headers and you will be where you want to be with that engine.

 

the cam in the 86 motors arent as good as the motor in mine....87-93 or 89-93 had more hp than all the others...so i would recommend getting a cam and some good flowing heads....if i find a place with 2 sets of explorer heads then ill let ya know and u could get them ...haha and dont get long tube headers...they lower your low end torque unless its getting blown or stroked....get some short equal lengths....302's dont put out enough exhaust to use the full potential of long tubes..

 

MEM the way I understand it, long tubes give you MORE low end torque. one of us has to be wrong[8D]

 

That's right EOC. Long tubes give you 8-12 ponies over the shorties, and increase the low end torque.

 

There's no way shorties are going to flow better than long tube.
