Pics of my 557 in my F-100

I think I'm ok with the short air cleaner. With my 472 I had o vacuum at wide open throttle through 6000 rpm. With this motor I'm to busy trying to keep it on the road to look at the gauge. Maybe after I put on my drag radials I'll be able to check.But until I get a load of mulch,the 32x12.5 reguls stay on. Randy.

SHooOrrt! bed!!!
Woot!
can I barrow it for the weekend??

Settle down Nomad, it's a long bed, so you don't want it...

Give it to me instead


Can't wait to see the drag strip results, please get some video! I'll be building a stroker for my '79 in a few years as well.

Nice looking engine and truck. Would love to see a video of it. BTW, how are you using pump gas with an 11:1 compression ratio?

 

[fordrka1975]

Torque Oplenty. You can get by with pump gas with aluminum heads,but that is about the limit. I have ran pump gas in a 466 with iron heads and about 10/1 compression by retarding the timing, but that cost horsepower.

 

[bucks77ford]

I should be able to run pump gas on my 521 with aluminum trickflows and a 10.5:1 compression. Right now I have an E85 carb to be able to run a higher Octane pump fuel since it is readily available in my area.

 

[fordrka1975]

I'm sure you will be able to run your 521 on 92 octane.

What heads did you get?

All this pump gas talk makes me sad lol.

 

[fordrka1975]

I'm running trickflow streets.

Like everyone else said... you better get someone in the stands with a video camera. I want to hear it too!
