Hello Guys,I'm building a motor for my 86' Mustang. It will be used for a daily driver
and have a mild gear (3.27) I want the motor to have torque, be streetable, but still have as
much top end as I can get. I am considering using a carb to keep the $ down. What: "Cam, Head, Carb, Intake" combination would you recommend for a very
hot (choppy idle) 393w motor that will be driven all most even day. How much H.P. do you guess it will have. Thanks Thanks

For the whole motor, I was hoping to spend $5-7000.

If you ever put slicks on it, and you drive it hard at all, you can kiss that T5 goodbye.Edit: I know multiple people that have fragged stock T5s with stock engines, and I know one guy that blew up a WC T5 with a car that dynoed at 280rwhp. It doesn't take much to break those trannies.

I would recommend AFR185 heads and either a Victor Jr or the new Air Gap Performer intake. Not sure how your hood clearance is. I run the 185's and a Victor Jr. on my 393. The 205's weren't out yet or I would have chosen them since mine is a strip car. But they are 500hp capable out of the box if put with the right setup. I also run a 850dp and it seems to be a good fit for my combo. Again with the right combination the 393 is quite capable of making 500hp.------------------

Well, thanks Guys. Looks like the collective opinion is AFR 185's, AirGap, and 800-850 DP.
Still not real sure on the Cam, but I was thinking one in the 2000-6000 range for manageable street.
Yeah, I thought about a Tremec, but I heard they didn't shift well, clunky?

The supplied shifters are sloppy, but Pro 5.0 makes nice, precise shifters for them. It's still not quite as smooth as a T5, but it does shift cleanly.

I'm suprised that no one has recomended the Roush 200 iron heads since the iron vs. aluminum debate.
The Roush 200 heads are comparable (if ported and cleaned up) to the AFR 185 heads.
Cheaper too.....

yup im using the roush heads fully ported they will just as much power and more on my 408, did a lot of planning between the two heads, alum and cast from very smart engine guys the cast iron for street car is the way to go.

Yeah, thats what the "old man" builder said here in my town too, iron over alum on street, but like everyone said Victor Jr. and/or AFR's flow better than World. ...Then if you pay for (and can find) a good port job for World Heads, they're as much or more than the Alum. ones!?!
So, "StrokerMan", these new Roush (world) heads, do they need porting right out of the box as well? Did "right cast" technology do anything for them?

Seems like it comes down to how you use your car. If you depend on your car, get iron. I got a set of Vic Jrs because my car is hardly driven, but driven hard.

10-4, well I would be depending on it. Hum, so the miss-match in expansion rates of Alum & iron breaks things....eventually.Anyone.. Do the new Roush 200 Heads need porting and/or polishing, or are they useable as is? (hum, Mpcoluv says not, but the little sales blurb says they are)

Ok, I just read a message about the Roush heads. So all they need is a very light de-burring. Not like "porting". I think I could do that myself? (I ruined a set of 351c heads before trying it) ((just a little more, just a little more....lol))

Roush took the World heads and put alot of effort into optimizing them. I would just clean them up as needed and go.
