afr 185s or 205s for my 331?

[Modular2v]

plan on going with a trick flow stage 3 cam.....the car is carbed with an AOD and 4.30 gears, will the 205s be too much for the car? The car is probably not even going to see 300 miles a month of street use

Go custom on the cam and get 205s.

so if i were to drive the car on the street the 205s would still be ok as far as streetability?

 

[green]

they say 205,s are best for engines makeing 500+ horsepower, but i may be wrong.

 

[Modular2v]

but wouldnt the 205s be part of the reason a motor is making 500+ hp?

They'd be like 185s on a 302. As long as you have a matching intake and cam they'll be fine. Keep the gear, and seriously, go custom on the cam. I'd go to FTI.

The TFS 3 is a good cam and I would go with the 205's,what size carb you looking at?

 

[Modular2v]

i have a holley 750 dp on the car right now

Victor Jr. or simalar intake?

 

[Modular2v]

yes i have a lightly ported victor jr intake

 

[bluevenom867]

yes i have a lightly ported victor jr intake

Yor good to go then

 

[Modular2v]

just out of curiousity how much power would i be pushing with a tfstage 3 cam, the afr 205s and that vic jr intake on my 331?

 

[Modular2v]

and please tell me an 11 second pass is going to be possible!

I dunno, but if you really wail on the car you might miss them entirely.

I really dont know, but there are quite a few that have scraped high 11s with engines similar to mine(ie. alot less than you will have).

I like the 185s on a 331. My buddy made 365rwhp with his 185s out of the box with a Victor Jr intake and a Custom grind cam. We havent tracked his car yet but we are guessing deep in 11s, because he pulls the ***** out of my 12second mach. I think the 205s might be a bit large for a 331

 

[$uperstang]

185's! 205's are good for high end 347's or 351's

 

[Modular2v]

so 205s would hurt the car?

 

[bluevenom867]

No,the 205's are just right.

You need the extra airflow at the track,as you not concered with low-mid torque,thats what the 4.30 gears are for.You deffenitaly dont want the heads as a restriction.

thats what i was thinking.....to be honest streetablilty is not that much of a concern. I dont think the car is going to see very much street time at all. One of my buddys can hook me up a set of the bad a$$ canfield heads with a matching cam for 1800$ fully assembeled and fully cnc'ed.

Get a cam that can spin r's without float ... you'll need to keep the combo spinning pretty good just to enjoy it ...
