Default RE: 5.0 400 HP - How to build

Wow, a lot to consider here. I'd like to stay with the EFI. Is there perhaps a crate motor that is a better starting point? Good power with the ability to accept power adders later?

Yes you can. You just gotta know what parts work and your going to have to shop around for those parts instead of pulling out the Summit catalog and a credit card. But its going to be a carb set up, they just respond better to modifications than EFI motors do. Not to mention being a ton cheaper to build.

ok, but don't you agree that once everything is said and done, if you want it to still drive around well, then you're gonna spend more than 5k.

sorry for the double post but i guess you probably could. I've been looking at suspension and stuff of that nature and it's not that expensive. i'm also sure that you know alot more about it than i do stangaruu.

Nah man, you just gotta find people that have what you want and then talk them down in price on it. Alot of it is common knowledge. You can get a video tape or take a class to teach you to rebuild an engine. Then your going to have to ask people what works and what doesnt work. Go up to some racers at the strip or whatever and just ask, more than likely they'll just tell you what you want to know if your nice and respectfull to them. And LISTEN, listen and record in your head everything they tell you. And act as innocent as possible, puppy dog look helps [sm=insomnia.gif]

Its mainly in the heads. Its no lie your going to have to know what your doing on this. If your running some cheap Iron heads, your going to have do take some time and really work them over nicely. Its going to take a loooonnngggg time to get them ported to the extent of what you need. But if you know what your doing then be happy because its free.

Most of it is just picking your parts wisely. Dont go spending money on $200 valve covers, or $70 on chrome dress up kits. Spend that money on something else, like some decent valve springs.

i believe thats the Advertised duration. The 0.050 duration would be far less than that.

Default RE: 5.0 400 HP - How to build

i would go with the afr 185s with the upgraded valve springs for high rev, edelbrock victor intake for the high revs and a cam with atleast 300* duration to match the intake for high revs. I would also swap out the pistons for somehting with higher CR. thats about 3grand tops right there. get your self a main girdle, bigger inectors and mass air-find em cheap on ebay, maybe used. A good fuel pump and better fuel rails. then you will have a few hundred left to play with for gaskets, maybe throw some main and rod bearings in depending on your the miles. that would get you dam close to 400. but its really tight on your budget and things are gonna go wrong or your gonna need this and that as you go along with the build.
