a Blown 540 or a N/A 598???
....Ok, I'm rethinking my 'game plan' on my '32 Ford. My new idea is to use
either a Blown 540 or an N/A 598. If I go with the blown 540 I'll have it set up
as a blower motor but not put the blower on right away. I'm going to go with a Scott Shafiroff short block with roller cam {which I can get on August 1st.}, then on September 1st. I can get
the heads {Dart 355's that are ported, is what they recommended} and then
the Intake Manafold, Carb, ignition & the rest of the misc. stuff on Oct. 1st.
If I get the 598 I'm good to go at this point. Now if I get the 540 {it doesn't
cost that much less, but they said that I can't get the compression down enough with the 598 to blow it} then I'b be set up but without a blower. I will add that
later, after I take delivery of the car. They say that their 594 will put out around 750 H.P. They said that the blown 540 will put out over 1000 HP. They
are trying to discourage me from the blown 540. "It'll be to powerfull, it'll be so fast that it'll be dangerious, don't get 'caught up in a numbers game', we have a lot of customers that get 'carried away' and just want to de-tune them in the future & so on". I used to drive a 450 HP, 499 Ft. Lbs. 2800 Lb. car on the street, It wasn't fast enough. I've ridden in a car that turned a
9.97 @ 138, it didn't seem THAT fast. Fast, but not anything scary.... What do you guys and gals think??? What would you do??? Will the biggest street legal tires that they make hook with a 1000 HP??? {oh were talking flywheel HP, buy the way}. I just don't want to go with the 598 and want MORE HP down the road a ways!!!
Thanks, Bill
Oh, it'll be a street car, 9" rear end, 400 Turbo trans {+ trans brake}, 4 link rear end, weight around 2500 to 2700 Lbs..... Oh, I'm in California so 91 oct. is as good as it gets......

Re: a Blown 540 or a N/A 598???
I think that you know how much speed you can handle.
As to HP, I seriously question how effectively you can hook up even 750hp in a light car like that, unless you plan to use a drag race type of suspension and some fairly large tires. Maybe you do.
As to money, you know what you can spend.
All I can tell you is what I would do with that same choice. That may have nothing to do with what YOU want to do.
I would go with the larger engine and put a tunnel ram on top of it. Not for HP... I suspect you'll have more than you can use anyway. I would do it because you just don't see tunnel ram cars anymore and I'm feeling nostalgiac these days.
If you want to do a blown car, just buy a 502 from Scoggin-Dickey, which has a fully forged bottom end and 8.5:1 compression and drop an 8-71 on top of it. I think that would be more cost effective.
Look, this isn't really about HP.
It's not really all that hard to make 1,000 hp with a $10,000 engine budget and just using off the shelf parts. HP isn't even the issue anymore. The guys who are on the leading edge of HP these days, in terms of street cars, are in the 1400-1500 and beyond range. Like those nutty turbo guys.
If you want a big HP car these days, your big challenge is really in terms of keeping your tranny/rear alive and putting the power to the ground.
But YOUR choice, what YOU are trying to decide... It strikes me as more of an esthetic choice.
So let me ask YOU a question...
Are you trying to be cost effective or are you trying to do something "cool".
Don't say 'both', pick one as a priority.
Once you do that, I think things will become more clear to you.

I vote blown 540.
Much more streetable and having power down low will make it alot more fun the drive on the street than a high revving,2 seconds between each cylinder firing, 598.
Just my opinion.

Tires & suspension? My thinking was that I'd use the biggest street legal tires and the best hooking that will fit on a 12" rim. For the drags, if I ever go, I already have a set of 15" Convo Pros for that. And run real slicks. I had them put a 4 link in it. Pete and Jakes did the chassis.....
Money??? Well of course money is the only thing that holds anyone back [or at least 99% or us rodders}. I can one way or the other go either way. It'll take me 3 to 4 months to gather parts for the 598. The blower motor I'll have built, put in the car and then add the blower later, but thats ok. With the blown motor I could just run lots of boost with race gas at the races if I wanted to go faster. Actually I'll have the short block money together on Aug. 1st.....
Cost effective or Cool??? Oh, cost effective {at least for the motor}. Its a '32 3 window with a 3" chop in front & 2 3/4" in rear}. Thats already Cool {at least in MY opinion}.
HP??? Actally I should have worded this different. What I want is Torque! Steve Shafiroff said I'd have between 700 & 800 on the Torque and H.P. I should have said TQ. I would rule out a tunnle ram because of this although it sure would look nice!!! {or COOL!!!
. My Turbo 400 should be ok, I went through 2 700R4's before I had my Turbo 400 built. When I had it built I told the guy to build it for 1500 HP!!! Even though I only had 499 Tq. & 440 Hp. I got tired of being 'under built'. Plus I had NO idea of what I'd do in the future. The 9" rear should be ok. May be an up grade on the axles......SD 502??? I checked on this and a Shafiroff 540 is the same money. Plus with Shafiroff I would use better heads than the 502 comes with. Is there any reason that you would go with SD over Shafiroff???
So since its 'cost effective' & not 'cool' I guess it'd be the blower on a 540???
And remember that I said "add the blower later???" Who knows may be the car would have enough TQ. WITHOUT the blower! Yeah, its not as if a 540 set up for a blower {low compression & blower cam} with a carb & manafold would be a pig or anything!!!
Thanks a bunch LameRandomName, Bill

... But I don't understand how a 598 would be so high revving. And the part about 2 seconds between each cylinder firing??? Is that because of the long stroke/??? I thought the 598 would be a TQ monster??? But the blown 540 would have THAT much more Tq.??? Thank You Rice Killer 87, Bill
ps, although I guess that EITHER motor would kill most rice, huh???

Re: a Blown 540 or a N/A 598???
I had a feeling you were talking to Scott & Company.
Ask him if he still has that '77 around. That car was just AMAZING when he built it.
Anyhow, if you want to do the blown 540, that's fine, but my newest car ****... er... I mean my newest Scoggin-Dickey catalogue lists a brand new 425/454 HO for $4,899.80. That has a fully forged bottom end, 8.75:1 compression and Rectangle Port iron heads. In other words, it's a perfect blower motor.
I have never seen one of those engines put out less than 450hp and some put out more like 470. (I think S-D is just being cautious, in light of the HP scandals in the last few years.)
Car craft bolted on, I think... a YS trim blower and got 780hp. The details are fuzzy for me. Point is, a 6-71 or 8-71 on top of that engine will get you the big HP numbers you are looking for in a pretty cost effective manner.
Of course, you might be looking for those Schaffirof valve covers...
Anyhow, those are my thoughts on the "cost effective" choice.
Whatever you decide; have fun!

Rich
it's easy to sit at the computer and build your engine without keeping in mind
the end product. Do I REALLY want a blower in my face all the time???
Now I'm just confussed. One minute I want a 598 w/out the blower & the next
I want a 540 {or 509} with one! Thanks a lot for the imput

**** on you for having the kind of money it takes to wonder if you should get a blown 540 or a 598....but, i don't blame you for spending it if you have it. Personally, i'd go with a blown 540, its just a more versitile engine, easier to drive. But then that may be my inexperience talking

Haha! Well, with age comes wisdom right? Anyway you're right, it is all relative. Eventually i hope to only get jealous watching F-1 and the 24 hours at LeMans, but we'll see. Goodluck with that motor though.
