Hi.

I'm gonna start to build a new engine for my -80 Aspen and would like to get 450-500hp. Any help I can get would be nice. I will use a roots supercharger e85.

Thanks.

Welcome!

At the boost required to make 450hp you're better off with a turbocharger or a screw compressor than a Roots blower.

While there are some very fast carbureted turbo cars many (most?) use alcohol injection as a supplemental fuel and detonation suppressant. EFI I feel is a good choice as it gives a lot more control over fuel and ignition which helps keep pistons and head gaskets healthy.

I highly recommend spending some time in the boost and nitrous section and reading about head gaskets, o-rings and head studs.

You may want to give serious consideration to beefing up brakes and suspension with that kind of power.

Being conservative?
Only 450-500 HP?

Yes I will upgrade because I think the 100hp is almost to much for the brakes and suspension.

In all honesty, there really isn't much difference between blocks.

What blower are you going to use?

Member terry littlejohn is using a 6-71 and can probably be a lot of help to you. :D

...is this a strip car or a street car? 450+ hp from a slant is awesome. If a strip car, people will be impressed (as they should), but if a street car, people will be in awe, jaw-dropping power from an I6....love it.

Terry might be using a 4-71.

Seymour had a buddy with a 4-71 back in the late '90s. IIRC, it made well over 400 back then.

It will be a street car :D there are a couple of people in the city close to where i live that say the slant is a crappy engine(they have 320-360 V8 with under 350hp)So I want to se their reaction when the car is ready.

The Slant 6 seems to respond very well to boost. We hope your project goes very well! There are a few other cars in Scandinavia (Finland included) on this site.
