Looking at this 408w stroker kit.
http://www.summitrac...ts/SCA-1-94305/

AFR 205s(72), .075 MLS head gaskets, .579 lift cam so basically the compression would be right at 10 and motor wont see over 6200rpms.
Just looking to make around 550hp and seeing if anyone thinks this kit is safe for that.

I don't see why it wouldn't get the job done. The only suggestions I would give is if your dead set on running afr heads and you haven't bought them yet, I would go with a bigger set so that you can grow with them. A 408 has a longer stroke than a 460 Ford. It will also be cheaper in the long run.

Also have you checked FordStrokers.com, for the rotating assembly.He uses scat parts but with a lighter probe piston. The thing I don't like about the summit kit is it doesn't say for sure what brand of piston you are getting. It just list numerous brands that "might" come with it.

fordstrokers.com doesnt sell rotating assemblys anymore, just shortblocks.
Also summit doesnt list it, but if you take the part number and go to another site, that kit comes with mahle forged pistons 11cc. Just like their 331 kit if you look it up, comes with KB Icon forged pistons.
They used scat parts with the probe pistons cause they are the exact same kits probe industries sells themselves, but of course cheaper.

225s are a little on the big side for what Im doing. AFR recommended me the 185s for a street car but that is not gonna flow enough air for that many cubic inches.

I didn't know that about Fordstokers. As far as the 225 being to big for a 408 I don't really agree with that but I'm not about to get into a "heads are too big debate". All I have to say is look at the size of the L92 heads used on GM 6.2 "Truck" engines and report back about the 225's being to big on a 408 cubic inch engine. Its all in the combo not one magical part.

As far as AFR's recomendation, of course they would recomend a smaller head, because it will benefit them when the smaller head becomes boring and you want to go faster. So now you want to sell off your small shit and buy bigger. See how that works.

ya, just 550fwhp. Only looking to run around 6200rpms or so, plus stay streetable. Thats why Im only choosing that size of a cam to stay in the power range I want to be in. Getting a cam where its gonna be making peak power at 7000-7500rpms wont do me any good.

I found a article on that cam and it so happend to be on a 408. They could only pull 9 inches of vacuum with the cam. Only thing Im gonna be running vacuum wise is the brake booster so I should be ok. Just trying to make as much power as possible and if I feel like it, I can drive it to the grocery store, lol.

mine was close. but i had to spin it pretty tight....... i left at 72, shifted about 7400.


i could be dead wrong, but with those parts, id think youd be hard pressed to make that power at that rpm.

Driving a 9 sec import is kinda like comming out of the closet. Sure you might surprise a few people at first, but in the end you are still gay.

Maybe just sticking with a 306 with a blower will get me my 550hp easier. Mild top end and complete street friendly.

If I was going to use it on the street I would stick with this combo, or budget turbo

Ive been reading a lot of engine dyno tests. Just a 347, afr 185s, comp 282 cam, rpm II intake is making 450fwhp. Dont see how slapping little more lift, 205s and an extra 61 cubic inches cant pull off another 100hp easily.

A 408 needs a lot of head, I think 205s are to small.

Damn, I wish you would have posted this a month ago, I just sold a big bore 434ci motor CHEAP with a streetable cam would have made around 700 :cheers:

Rick,
Are you building a motor to "achieve" a certain horsepower number or do you want to do something with it? What are your goals?

I want it streetable, not some 700hp+ monster. I want to be able to go cruise around also. 550hp I think is a resonable goal for a 408 and still have some manners to it. 6000rpms is around what Im looking for, 1 the motor will last longer, 2 gives a good rpm range for a cam that doesnt have to be insane. Pushing it through a 3550, 4.10 gears, only running alternator and power steering pump.

But at the sametime, a mild 302 with forced induction to pull 550hp is pretty easy too, even on a stock BLOCK(not shortblock) and get some good life out of it. Its cheap now to get a forged 331 scat kit with a 9 compression
