I have ordered my 331 stroker kit with the forged pistons.What would be a good solid camshaft for it.I will probably be using AFR 225 heads and vic. jr. intake.I will probably drive the 65 mustang bout 3 days a week on the street.It will have 3:80 gears.Also will it be better with a toploader 4-speed or a T-5 from a 86 mustang G.T.What type of horse power would I espect to get from this stroker.I really do need to know what a good solid cam would be even a part number would help for ordering purposes.

AFR 225s will be too big unless you want to spin it 7500+RPMs but the AFR 185s would be just right up to 7500RPM. The Victor Jr intake is too restrictive for the AFR 225 heads. You will need the Super Vr 302 intake if using the AFR 225 heads and spin the piss out of it. Victor Jr and AFR 185 heads would be a great match though.

Ditto... 205's will be too big, and 3.08's wont be a good gear.

You would be better off with 185's AFR's and something like a Trick Flow Stage 2 cam (hydraulic roller, 224/232 about .560's lift)

On a Scat 331 stroker with AFR 185 heads, vic. jr intake, 650 prepped carb, this combo made 442 HP @ 6200 and over 400 lb torque from 3500 to 6200 - flywheel. Compression was around 10.5:1

WIth 3.08's you could be fine with those numbers, but with AFR 205's you'd relaly lose low end and need to spin to 7000+ to make those head work optimally, which would make the gearing really deficient.

We (FORDMUSCLE) also just ordered a 331 kit, we'll be doing that project in the next month or so.

damn dsylexia!

Well even then, I think 205's are a little too big unless he plans high rpm power (or a blower).

I just finished another 331. Catpep crank and rods. Flattop piston from SRP. Cam is from Ultradyne. Solid flat tappet. Lift is .586, and the duration @.050 is 248. For the carb combo we used a Victor Jr. and a demon 750. The heads are AFR 185's. Right out of the box. Simple yet very effective combo.

Unless you have a big cam and some real compression you will have very little low end at all and probably not much midrange either. I'd agree with the other guys about the 185s being better or if your gonna make big rpm maybe the 205s.

In my 331 I am using a Crower solid cam part #15322. Great cam! Run the numbers through desktop dyno and see what you think. I'm running the Windsor Jr. cast iron heads, which have been ported and valve upgraded. I am at 10.36 to 1. It has the 4340 forged crank, 4340 I-beam rods, a DSS crank girdle. It pulls hard all the way up to 7500, even then it feels like it wants to go more. Lots of fun! I have a top loader with the 4.11's and I am not happy with any extended freeway driving. It's crazy, going along at 65 with the motor reving 4000. No good. I'm going to swap out the gears with 3.50"s or something like that.

Hey Fordmanz. Where are you located? I've got a spare Toploader I might be willing to get rid of. I'm in Indiana. If your too far, shipping would kill you though. Email me if your interested.
