400rwhp N/A?
Junk the 2v heads, buy 4v DOHC FR500 heads, port the hell out of the heads and intake, put some nasty cams in, put some high compression pistons and stronger rods and crank, done.
yea i think youve made my mind up about the supercharger, i looked into the kenne bell kits, i cant find any site that sell them. i went to there homepage and didnt see any prices, just the product info. does anybody know where you can find them for sale? also will the motor run well with what comes in the kit?
I had everything you just mentioned and te car made right @ 300rwhp.... see the issue here is the small bore on this engine. it shrouds the valves which KILLS flow. it isnt an engine that does well in N/A applications... but with FI it outshines most.
I don't know much about V8's but I still don't get you guys?
You have 4.6L to work with...
If you want 400bhp N/A:
I agree on the 4v route, swap to 4v.
Change comp ratio, 10.5:1 should be ok.
Get new After market EFI and Ignition.
Some agressive cams.
New headers and exhaust.
Check the flow in the intake manifold and rebuild it if necessary.
Don't know how much that will do for you but I think it'll put you pretty close to the 400 mark if you do it right.
With a 10.5 comp you can still add a blower if you run on E85 or race gas.
I have never done any work on V8's all my experience com from tuning the crap out of european 4-bangers.
I did got the 4v route
and adding race fuel to the equation changes everything, I assume he is talking about a street car though. Needing race fuel is not a street car in my eyes.
Well Shiver me timbers.. That's twice this week I ate my foot.\
