looking for input on building a motor for an F1A
looking for input on building a motor for an F1A looking at building an iron block 408 using a F1A with around 18lbs of boost or so. I would like to make 850+rwhp. It will be going in a 99 camaro. I don't mind notching the cowl, but don't want to lose the wipers yet.
The question is what heads to use? Seems like the afr 225's are a tried and true head, and I can use a vic jr intake and only notch the cowl a little. Or would a ls7 style head make more power? and what intake could I use that won't require losing the cowl?
Thanks

In hp levels over 1000, but under that they do fine. Sounds like you passing on info you heard from others. They tune in fine and there are many of theses out there running nicely.

Verdad Gallardo thanks for the info guys. I am planning on using pump gas with a meth kit. I also looked at the TEA TFS235's. That might be a good choice. I already have a cowl hood, so not worried about clearance. I can't see how the ls6 could be as good as a carb style or hi ram, but maybe it is. The holley hi ram would be great, but do you lose the wipers with that one?
If you are running a single plane with boost, 4bbl TB and a EV hat is the only way to go, but I would still opt for the tunnel ram
put the money elsewhere, you can always sell it and swap it later for fun and see what it picks up for reference.
If I had an ls6, I would prolly try it first and see. But since I would need to buy one, I'd rather buy the best one for the combo. Anyone using the holley hi-ram? How is it? likes, dislikes?
that is so far from accurate or true its not even funny. On cars with 6-700hp the cyl to cyl EGT spread is already HUGE, ive witnessed it with my own one good eye. And running nicely to you and running with 2 cyl on the edge of knock while the other 6 are far from it is not "running nicely" to me. Sounds like you are passing on bullshit you heard from others while you have no clue.

Maybe you were reading or typing with your one good eye, lol. I know a little more than you might think. With methanol and the right plug its safe. If you are running on the ragged edge of knock then yes its not safe. If timing is backed off to a safe limit, then yes it runs NICELY. Show some proof of the egt spread on a car with conservative timing and methanol. I under stand they can vary but keep timing at a safe limit and spray some methanol on it and its not a problem. There are a lot of big powered cars running this setup and still alive. I do understand what you are saying and yes its true, but in the lower hp cars its not a critical. One last thing, does it suck to be angry all the time?

Id just go with a ls6 intake or if you want to make alittle more power on a little less boost go with a fast 102. I made over 800 on a slock ls6 and stcok 78mm TB. Theres no need to get all crazy and buy some baller *** intake setup when you not tryi g to make big dog power
I agree, you can run into the 8's in the 1/4 with an LS6 intake. I have seen some of the older LS6 intakes start to crack though under boost, so you would be better off with a newer one. A FAST 92 or 102 will also do the job. Bob
