Is there anything else you need to know?

I'm hoping for about 470 hp and 500 ft/lbs.

edit 1.6RR's

 

Here you go. I don't have the AFR 195 head file so I used the AFR 190 file, which I assume is pretty close.

 

And here is the data tables. It looks like you are able to achieve your goals

 

Those numbers are incorrect. You need to change the manifold type from "dual plane" to "Tuned Port". Then look at the numbers drop.....
Sorry.

 

OK, I just saw the TB for induction and thought straight throttle body. Anyway, it dropped about 30 in the hp and virtually not at all in the torque, so it will still be pretty close to what is desired.

 

And here are the tables.

 

Just curious where you guys are getting your Air Flow Files from? Im kinda tired of having to put every head I do by hand. Any help appreciated!

 

Thanks so much for doing that for me! I really appreciate it.

 

Could you run it with a LT4 hotcam and 1 3/4 headers?

 

OK, here it is with the Hot Cam. I don't know whether your AFR195 heads have 2.02 intake valves or not, so I told the program it did. If not just subtract about 10 hp.

The program doesn't allow for inputting header sizes directly. It just goes from "Small tube headers" to "Large tube headers." 1 3/4" headers would still fall into the small category and at this hp level there is only a 5 or 6 hp difference between the two.

 

As you can see, the Hot Cam isn't the ticket for this engine. I think it has less duration than the Comp and that's why it produces less power. However, it might be more manageable as a street car.

 

UGH..... are 1 3/4 headers considered small tube???

 

Yup.

It is when you get into the 2 inch variety that it moves to big.

 

So how much gas mileage do yall think this engine will make? I'm hoping for over 15mpg.

 

Ho, ho!!!

460 hp and he wants mileage too???

15 mpg on the highway, maybe--in overdrive with your foot resting on an egg

 

This is actually MrsLottaBalls posting thru his account. He doesn't care about mileage at all! But I'm the one who handles the money, so I'm just wondering how much gas this is going to cost us. I was hopeful that we might make 15, but I'm thinking realistically more like 10-12mpg.

 

It is the thought a huge gas bills that keeps me happy with my 'lil ol' 305, so I know where you're coming from!

 

I have a 305 RS and a 350 IROC, and the RS gets about 21-22mpg and the IROC gets about 19-20mpg. That's enough for me. And when we put in the 383, the IROC will be just a weekend fun car, so the gas bill won't be too much!
