1050 Dominator carb
Victor intake
MSD ignition
.060 over Probe flat-top pistons
Factory 1969 crankshaft
Eagle rods DOVE heads
A .622 lift solid lifter camshaft

I bought the car like it is. The rest of the specs are:

33/14.5/15 rear tire
4.11 gears
C6 with 3500 rpm stall converter

Currently, it runs 10.80 in the quarter. I know it needs more gear and converter, but I want to go to a head that will make more power. This is all in a '81 Mustang. I use it for racing only and it weights 2600 lbs. I would like to run mid 9s.

What head will bolt on with this set-up without having to change a bunch of other things? I would like to just remove my existing heads and bolt on another set without having to do work on the short-block. Is there a good bolt-on head that makes big power that will use my roller rockers and other components? I need about 700 hp to do what I need. I figure I can get a half a second with a gear and converter change, and some tuning. It is a slug out of the hole.

This is my first BBF car, and I can use all the help. I was a Chevy man until I built my 351 Maverick, and I saw how Fords run, so now I'm trying a BBF.

Thank you for any help.

I hope you don't mind me editing your post a little. Helps me to see and answer your questions better.

First of all, it does not take 700 hp to do 9.5s with your weight. I'm assuming the 2600 lbs is wet weight with you in it. It will take about 600 hp, if you get the rest of the combo dialed in.

Second, I would suggest you use your existing heads. Send your heads and intake to Scott Johnson, http://www.reincarnation-automotive.com/ Have him install larger valves, do Stage III porting on intake and exhaust ports, Victor port match, and chamber mods. Have him CC heads, and equalize them to 72 cc. Also, have him install new hardware. You can then use your existing rocker arms. You will need to to check your valvetrain geometry, and may have to order new push-rods. This being done, your heads will be able to support 700-750 hp, with the correct supporting components. Installing these heads on your existing shortblock will not produce 700-750, as you need more compression and a large roller cam.

Third, send your existing carb to Bob, http://competitioncarburetion.com/ and have him tune it for your combo.

These two changes will make a big difference, and you may need further changes to the shortblock and drivetrain/suspension to fulfill your desire to run mid 9s.

Hope that helps,

Dave

If your going to spend good money on the iron heads, may as well just get it over with and get some aluminum heads you'll be ahead of the game and loose some more weight in the process.

thanks for edit,i do the best i can ,im new to computers this year,ive never typed anything prolly in 25 yrs till this year,i have made several changes i recurved the dist.,the throttle responce is amazing now,i tuned the carb the best i could ,the car ran 7.40s when i got it ,i now have it in the 6.90s,i bought s 5.00 gear for it this week,now maybe i can shift higher, it was taking all day to get to 5500 with the 4.11 gear and the slow timing it had, now it seems to rev crazy when i hit the throttle,im hoping to shift 6200 it loves rpm the higher i was shifting the better it ran, ive only had 10 passes so far, gained .5 seconds, it needs a looser conv. but like i was advised ,im waiting to see where i go with a cam and headers,but im loving the bbf ,i was always a bbc man ,and i aint saying anything bad about bbc they flat run, but i wanted to do something different was just bored,ive also raced a blown e85 injected s10 10.5 tire truck. in open comp some at milan and us41 ,on e85, last year i bought a maverick and built a 351w ,and loved that car traded for this ,so guess im crossing over to the dark side lol......and loving it

That may be true, but it is also fun when the competition finds out they just got whupped by factory car passenger iron (aka lead-sled heads, LOL). For what Jay wants to accomplish, the iron heads are more than enough, albeit, at a price.

Dave

Jay should tell more about himself -- like who he worked for and what he did.

for a car to use for a ref . point use 1970 t-bird 429

where do you race at? 41?

converter sounds too tight for n/a, trans brake ?

bunkerhill ,but trying to get to us41 maybe next wenes , yea this conv is a joke i cant even hold it on the starting line above 1400,lol it maybe flashes 2200 ,but i recurved the dist. hoping to help pull it a little more maybe get 3200 ,i only had 6 to 8 deg. timing before at 2200

DONT TAKE THIS WRONG!!! but total timing is what you need to know, base doesnt mean anything if you dont know your total

Hey BOSS 429, pretty sure he knows that. He is just trying to get more torque down there for the converter.

your right fordman ,i have 36 total now, with 28 at the start and ill work with it from there, by the way has anyone seen my car before, im trying to find who built it, so i can get info, i think its from michigan

Hey Jay are those 4.11 gears for a 9"?
If so are they for sale?
I plan on going to NLR "US41" next wednesday if I get the truck back together.
Let me know
mike

yea they will be for sale
ill let you know when i get them out id like to get it done monday or tuesday, and rm thanks ,i dont really need anything from you including you smart comments....your classless..........
