More results from my 3500Z!

25 hp less then your expectations but still very impressive numbers, for what really boils down to not much work.

Heads, cam and intake, picked up 100ish hp.

Where's the video/graphs? I'm getting anxious to see!

[98malibu3.1]

273.7 WHP and 257.25 WTQ!

Which is around 315 HP and 296 TQ at the crank..


13.992 @ 103.64MPH was my best time of the night, it cooled off nicely but right after that we got rained out so i didn't get any more runs in..


I'll post up the timeslip, videos, dyno graph and the dyno run breakdown sheet with wideband data later (been a long day).



Later,

Dude, that kicks ass!! Almost 100hp/L.....very impressive for an old pushrod 2 valve V6.

I imagine it might be possible but the runners would be close to non-exsistant. But with boost especially roots style where you make it right off idle it may not be that much of an issue. Cruise without boost might suffer power and mileage though. The main problem is the 60* is narrow so anything on top of the heads has to sit up high. That's why the lower intake is part of the valve cover. Everything is packed so tight.

But yeah back on topic, Dave when are you getting pics/vids!!!!!!

I would like to see what this new LIM looks like for the M90 setup. If you can save 2.5"+ from the traditional mount on UIM style setups that would be awesome and I might be interested for the right price.

[Sidewinder]

Oh ok, I misunderstood. The only setup I've seen was the guy cut a chunk out of the upper manifold and mounted the M90 on that, which is what I thought you meant.

No, I haven't seen an M90 up close, don't know anyone with an L67 nor have a seen one in a junkyard.

I've actually been wondering what the cost would be for a custom lower intake to mount an M90 onto, would definitely be interesting to see.

[blackbombshell95]

Just amazing.

[ForcedFirebird]

Why not make a custom lower intake manifold to mate the M90 to instead of modifying the upper? Or is the M90 too wide?

That's the idea, but have you ever seen and M90 up close?

[PCGUY112887]

Yeah clearance would be a big issue. I would be sweet to keep it all under the hood, but I know it can't all fit.

[ForcedFirebird]

I would def do it in the future if CNC guy made a manifold for it!

I need to find out if he finished it. I have a few CNC machines, and would be willing to make some in the near future. I don't know about clearance on FWD hood, though.

[ForcedFirebird]

I guess I'll just have to weld an M90 onto a spare 3500 upper to beat ya guys

Would you like to see a custom manifold to use it? I saw CNC guy was making something that would work, now I want to try.

Mine will be 11:1 compression while N/A, then around 8.7:1 for boost

Dave, what head gaskets did you use?
