A new hypothesis ...

[1sicklx]

:hmm:

331 ... NA

Heads ... AFR 165 or AFR 185
Cam ... open to suggestion
Intake ... Systemax II

:shrug:

[QWKSNKE]

185's would work well on a 331

cam....custom for your application

[1sicklx]

What kind of power would you suppose that combo would put down ... theoretically speaking ...

Your going to have to be a whole lot more specific if you want a HP estimate. Like what type compression, which set of heads you posted, cam choice etc. But a well built 331 won't have a problem making 400 flywheel HP and up.

I also suggest AFR 185's from the choices you gave. Especially with that intake.

:werd: Like Brad said, the camshaft and other parts of the application will determine the power. SLVRBULLIT has a 331 with most of the supporting parts; it did a very nice 316 rwhp...not broken in fully. I've seen 331's and 347's range anywhere from 285 rwhp up to over 400 rwhp...all N/A. SO there's a big margin there. Cam will play a huge role.

:think: ok, ... AFR 185's .... cam suggestions? custom? by whom?

:D

[1sicklx]

Also what would be a good compression ratio to serve as dailey driver if need be ... balance of power and reliability is the goal of this hypothesis ...

I suggest, when you have decided on all other supporting parts, to call Comp and have them suggest a good cam for your combo.

Personally, I would try and stay around 10-1 and under. And that's simply so if you decide to go boost later, you'll have a better comp. ratio for it.

Just my .02.

:nice:

[1sicklx]

any other heads that should be considered as opposed to AFR?

[slvrbullit]

I have the Edlebrock RPM heads, Typhoon intake, Comp Cams 35-302-8 grind nitrous cam, 10.5:1 copression ratio. My car weighs in at about 3200 with me in it and runs 12.3's driving conservatively due to transmission is stock. All the hp calculators have me making around 350rwhp N/A. So that puts me at over 400 fwhp.

Like Brad said get all the main parts you want to go with and call Comp cams or Ed Curtis of FTI, I would go with calling Ed Cutris if I had it to do over again and may end up going that route shortly. He knows how to get them breathing well, there are a couple guys on stangnet that have his cam and one is running 12.0's in a n/a 95 GT vert with a 302. Search on there for his screenname (killercanary) and look at his combination.

:nice: I'll have to check it out

Ahh, I did forget about Ed Curtis. Your right Tommy, he'd be a very good choice for a custom!

[coupe]

N/A 331 for the street...I'd run a cam somewhere around 226º (284º gross duration) and .540 lift. All on a 112º LSA (X-303 would be nice).
If you use 185's, add about 2º duration to the exhause since the 185's have relatively small exhaust ports...I would put Edelbrock Victor Jr's on the car...That cylinder head is awesome.

here is a comparision I found on stangnet.

Top is for head flow and the lower is for intake flow.

Buddy Rawls is also another good choice for a custom cam guy. Whichever one you go with, get involved with them early (read: get them on the payroll). Then, they can get truly involved with your head choice/block prep/compression choices. That way, it is all developed as a system "help me design a motor with xxx HP, xxx drivability, etc, as opposed to "give me the best cam to fit the combo I souced out".

It will be worth it in the long run.

From what I have seen, comparing Buddy to Ed:
• Ed seems to be a little more "race oriented". He likes large tube primaries, etc, on even daily driven combos.
• Buddy is a good ole' boy from AL, Ed is from north of the Mason/Dixon

I like Buddy's attitude better, and that is who I would go with if I were choosing. However, plenty of people like Ed really well too.

I've got a buddy in Knoxville (Michael Yount from the corral) who is a Mechanical Engineer, and LOVES the work this guy does. He is running one of his cams as well. He has a 1982 Volvo with a Ford 302/T5 in it, and it is awesome.

Yeah, I remember seeing that intake comparison a while back... it sucks that they didn't include any of the TFS intakes. :(

[1sicklx]

Yeah, seems they would have included some of the big hitters. but I have seen several comparisons in MM&FF ... for whatever they're worth :rolleyes:

that's because the trickflows were not available when those tests were done

[1sicklx]

ah .. yeah .. i see that test is from dec 00

didn't notice at first.
