I will be building a 408 over the winter and plan on running a procharger next year. My question is, in the build what do I need to watch for and what do I need to be aware of as far as the engine build goes? Any extra precautions to take? I will be running a pretty big procharger...but I haven't decided which one yet. Thanks

You may want to try searching the Forced Induction section on this site.

Just make sure the CR is low and don't make the mistake of getting a D1 or P1. Get the F1 straight from the get go and you will be MUCH happier...

I have been reading it all week. But I haven't come across anything like what I was looking for. And I have had no luck searching for anything in a long time. Seems like it is broken alot. Thanks

My D1/408 combo has made really good power, better than some peoples F1 setups. A D1 is definitely not a mistake, and unless this is a max effort drag car, either blower is going to be too much for the street anyway.

To the poster, one thing my builder did was go with 1/2" head studs to help with clamping.

This is a max effort drag car. It will never see the streets. I will definately go with head studs. Thanks

if it is a max effort drag car go eith f1-c or f1r

It sucks that search is crummy on this site. I don't know much about forced induction, but look into lowering compression ratio.

ill be doing a similar combo with a ls2 block over the winter as well... havnt made up my mind if ill be getting a procharger or a turbo yet... when i get this combo going - ill let ya know what im finding out... money will be tight so this may take longer than i think to build...

if this is a drag car you want higher compression... atleast 9.5:1 this will make alot more hp in the midrange and peak....

I would start with at least a F2. Run a vac pump, min 2" primaries / 3 1/2" collector headers, A/W intercooler or run on alcohol, blower cam, ~9:1 compression, 1/2" studs MSD digital 7, Fast system, ect.......
In a light race car 7 sec timeslips!

The problem on the LS1 f body cars has been the widest belt has been an 8 inch. With the 8 inch wide belt I really don't recommend going any bigger with the blower than an F1A. ATI Performance Products have just recently come out with a 10 rib wide belt assembly to use with ATI ProChargers on our f body's, which is going to change everything! Bob

I would start with at least a F2.

That is a lot of supercharger. I think a 454 would not be able to run a F2 to it full potential let alone a 408. A F2 flows 2700 CFM which is 700 CFM than a F1-R, 950 CFM more than a F1-C, and 1100 CFM than a F1.

I would look at a F1-C or a F1-R if you want to go pretty radical in a 408.

I run a D2R with 408ci in my stang. I believe it's rated at ~2800 CFM. For a race car I wouldn't consider anything smaller than a F2. The Ford guys are using F2's on smaller engines and making good power. For a street car I would have agree with you. However I would run a F2 on the street but I'm a little crazy.:twisted:

10 rib would be awesome, those guys are really in tune with the market.

I haven't heard anything about the 10 rib setup..hmmm.


The F1-r is the particular one I had in mind. Not set in stone or anything. Thanks guys. This is the kind of input I was looking for.

So higher compression like 9.5:1 for a drag only car??? I had thought about an LS2 block for my build, but wouldn't the iron block be better with the higher boost?

That is a greatly debated topic. They are lots of LS2 blocks out there, at 402 CID, making good power. I myself when with a LQ4 block for its extra strength.

OMG, what kind of power does that thing make.

The D2R was rated at 1600 HP and a max speed of 53,000 rpms. With it slow max speed and the fact that it doesn't like to to be over-spun. I doubt it could make 1600 HP. It could make 1100 RWHP but you had to lean on it. The F2 is a better blower and makes more power. I run a 50mm cog pulley setup. I wouldn't used a ribbed belt on a race car. Run a good BOV and it with work great. Good luck!

At that level of power, wouldnt a Cog setup be better in the end? Or is it just too much a PITA for LS1 fbodies?

Cog drive would be best. Even a 12 rib would be a step up. I have talked to a lot of people at Procharger and have been told that there will be no improvement over the 8 rib setup in the forseeable future. There is no market for it.

That's why I am rethinking and may go turbo.

I think its all on goals, there are some people on this forrum with goals I couldn't even dream about. I am going 408 with a d-1, well to begin with anyways. This will be pretty much a street car and I think I will be content with the power. I absolutly do not wanna go turbo for the street. So if a future upgrade is needed, then F1 it is. I have searched and talked to a couple guys on here with this combo and they are making great power while barely even running the d-1, 8-10psi. With the right set up, h/c, etc. You can make you results alot more efficient. Its all what yor after though so I can't reccommend anything, but it sounds like a f-1 is in store for you young grasshopper if the track will be its home. I have no clue on this one, may be some help here guys, but how would the f-1 be on the street with a 408? I guess it shouldn't be too bad would it?

I went with 408 stroker f1c and 19 -20 psi I'm pushing 931 to the wheels on a safe tune. Go f1 or f2 go big

F1 and bigger would be loud on the street.
