Default Check out my new combo.. does this sound right?

Ok, I've been doing some thinking and here's what I'm going to do. Let me know if you see anything wrong with it.

I'm buying a set of AFR 205's and having them flat milled .050. Going by 1cc for every .006 that is milled, that should put me at a 58cc combustion chamber. I'll be using the .040 cometic gasket. So my quench will be right around .033 since my pistons are around .007 out of the hole on my block. Running this thu my compression rato calculator, I'm getting really close to 12:1.. but I can back that up a touch because of my intake and exhaust flycuts, so lets say it is 2cc reliefs.. that puts me back to almost 11.5. I would really like to get 12:1, but it just won't happen with stock flycut pistons will it?

Here are some more questions. I'm planning on a 7.350 pushrod because of the milled heads, anybody see a problem with that? Also, is there another .040 compressed gasket besides the cometic's? Those SOB's are expensive.

Btw, anybody want to guess what cam I'm sticking in it?

Keep guessing LOL. That thing only made 6 more rwhp than my old 225 cam did.

What pushrod length are you running with your setup pdd? Also, rockers?

wonder how thick those Victor gaskets that I always use are? Can I just measure a used set with a caliper? Is that an accurate way to do it? They aren't but $11 each.

I'd guess youre gonna use the 225 again. It's much more suited for a H/C application.

Hmm...it kind of depends on what you are going to use the car for. Based on the higher compression, I would think it isn't a daily driver and a big cam would be in order. However, because of your earlier results, I am going to guess it is either the 225 or the F13. Am I right?

You don't want your quench less than .035". For best results you should set it between .035-.040. The felpro gaskets are .041, but aren't they set-up for a 4.100 bore? Better watch that P/V with that much milling.

The stock graphite gaskets are .052" thick. 7.350" pushrods are fine for that combo. I would check lifter preload to be on the safe side.

I personally would run the Cometic gasket well before the Felpro. You get what you pay for in this case.

If you need a little more compression and still have enough PtV, look into having the heads milled a little more.

Terry, what is the bore on the felpro #1041 .041 gasket you recommended ?
Good luck with your set-up Gomer those AFR's seem to shine under high compression.

Let us know how thick those victors are I am on the hunt for a non MLS thinner than stock (.54) headgasket myself.

I'm taking one of my used gaskets to work with me tomorrow (for some odd reason I have about a dozen used head gaskets in my garage ) and I'll measure the thickness on it.

The car gets driven a good bit, I drive it to work 3 or 4 days a week... 65 mile round trip. I drove it 160 miles total today.. in the rain. But it isn't bad at all, even with the big cam and 3.42's in it (I have a stock rear in while my 12 bolt is being rebuilt). I'm not afraid of compression, hell.. compression is what makes power, I'm going to try to get as close to 12:1 as I can.

As far as cams go, I "think" I'm going to dyno the car now with the current setup with the 10 bolt and 3.42's. Swap over to the MS3 with the heads I have now and dyno, then add the higher compression and AFR's and dyno again... I think that would be a good test. What do you guys think?

Sounds good...please post up how the driveability of the MS3 compares to the RJ. Im very curious.

The MS3 would be nice to see too. Not too many results out yet with it.

SOTP wise, which cam that you have used has "felt" the strongest? Is the reason you aren't going back to the F13 because you want to go bigger? How did you like the F13 compared to others, since you have tried so many?

Sorry about the questions, just interested. It seems like the F13 is the premier Futral cam, their others work well, but for all around, this is quite a cam IMO. I just want to hear more from people with actual experience. Thanks!

I think I may throw a set of stock 241's on the car too for some comparison if I can find somebody willing to let me borrow a set of valve springs to do it with. The best cam I've had in my car to date has been the F13 112 +2. I sold that cam to Jlaw here on the board a while back when I was thinking about putting the car back to stock.

I'm going to call Jason @ TSP and have him send me a MS3 out here... if they will ever get their phones fixed

how much different would you think the f11 would be to the f13...power wise, power range, and driveability? i'm trying to decide between the two...i'm not to keen on revving to 6500 or 7000 though..the engines gotta last me quite awhile

I have no experience with the F11, but I can tell you that my F13 112 +2 peaked at 6300rpm... so you wouldn't have to spin it too high at all.
