I find it intresting that people say the heads are too small...But then I read threads like this and I get really confused

https://mustangforums.com/forum/351-...gine-dyno.html

 

OP claims 357W Dyno sheet says 355 cubes. Hmmmmmm???? Would love to see the MPH at the track andactually know the exact weight with driver.

It also makes more power than an FRPP 393 Windsor shortblock with AFR 185 heads.

That's what I was getting at, all the above you listed will greatly affect the end result......ford strokers 347, woody said it should be around 10.5 to 1, camshaft is a custom FTI CAM........intake is a custom ported to the max rpm air gap, it's carbed and has a Bigs performance custom 750, rear gears are 3.73 for now, soon to go lower......lt headers, weight dunno, never weighed it, full weight car= no weight reduction..............the et and mph I will list is from when it had a unported intake, a standard 650 dp and a comp xe 282 cam and 3/8 1.6 rockers now has 7/16's.......anyway I only ran it 3 times then reconfigured the combo to what it is now but it ran a so-so time, 11.59 @119, I've yet to run it with the new configuration , still tuning on it, but it is whole lot faster now.........anyway what is your set up

 

Not bad. Looks like a runner!

My stuff is just junk. Comp custom flat solid cam with .659 and .667 lift
362 inches(3.50 stroke 4.060 bore) stock crank and rods with ARP rod bolts and Kieth Black Hyperutectic pistons with a 13 cc dish @ .005" below deck.
Compression is 9.8 to 1
heads are factory cast iron professionally ported with a 2.10 intake and a 1.650 exhaust
it is naturally aspirated
7/16 studs with 3/8 guide plates and comp red anodized aluminum roller rockers
Intake is carb set up and is a Funnel Web
Carb is an AED 750HOM (done to 850)
1 7/8 long tube with 3 inch collector and 3 inch exhaust with X pipe
T5 5 speed with 2.95 first gear
4.30 rear gear Car runs 2200 RPM @ 60 MPH on highway in 5th gear with the 4.30 gear and a 27 inch tall rear tire.
weight with driver 3250 pounds 1990 hatch back LX
time slip:
1.533 60 ft
101.12 1/8th
6.887 mph 1/8th
127.84 mph 1/4
10.749 1/4


Driven daily on the street, is a blast to drive and does not have any issues with highway driving and runs on 89 octane fuel. And No Power Adder.

I am very sure my heads are larger than AFR 185s and I really wish I would have went with a larger head on the same cubes. I know for sure I would be faster.

Junk....lol.......looks like it runs strong?......yeah mine to runs pump gas, although I'm at a cross road with it, cage or no cage?? lol.........with the new combo it should run low 11's or high 10's no power adder, it does have a 100 shot on it and I have only done 1 run on the bottle and it was an easy run, launch slow and no gear banging and it went 11.23 @ 126.....but I'd rather not use the bottle...the car is fully streetable as it sits but with the mph this thing is hitting and who knows where it'll be now, brakes should be upgraded, torque boxes should be reinforced, currently I ran weldsdown the seams, but it should also have a scatter shield and upgrade the axles from the 28 spline HD ones it has to 31's, as you can see, it's dump tons more money into it or just leave it as is and finally enjoy it, I only run the car once , twice if that a year, so I'm not sure it's worth it fiscally......but saftey is saftey

 

Yeah, I see your point. I installed a cage in mine. Plus I went to 31 slpine axles and I do have the lakewood bell in it with a ford racing drive shaft loop and the ford racing aluminum drive shaft.

Trouble is I want to go faster and I know right now I need to up the rear axles again for the new engine i am building for it. Plus I will be installing a TKO600 transmission. This time I am going stroker. 4.030 bore with 3.85 stroke. Heads have 51 cc chambers and the pistons have an 18cc dish. Still will be pump gas.

Head flow after porting:
Intake
.1- 80.3
.2- 157.4
.3- 228.9
.4- 293.2
.5- 330.0
.6- 366.5
.7- 389.0
.8- 404.5
.9- 405.9

Exhaust
.1- 60.5
.2- 115.0
.3- 156.4
.4- 184.1
.5- 217.0
.6- 240.1
.7- 251.3
.8- 260.3
.9- 265.0


Maybe everyone will think these are "TOO BIG" and all motor small block set up??
I am going to make them work on a pump gas street engine. Everything is almost done.

Joe

 

Are you saying those are the flow numbers for ported stock cast iron heads?

 

That's always the case.........I just for the moment have decided to be content

 

Umm nope,, I stated I am building a new engine. Those are my new small block Ford heads that I sent out and had ported.

But if anyone looked at them, they would say they are TOO BIG for a small block Ford.

Joe

 

What heads are those? Big flow numbers for sure.
