Default 408 with ls3 heads and super victor

I was looking at HVH spacers and wanted to know if there is any benefit to using this on my combo
lq4 408, -8 pistons
gm ( cnc ) out of the box heads ( going to mill to 65cc )
FI super victor with 4150 flange
fast tb - 1375 cfm
cam- hydraulic 247/262. lift 623/595 113-5
shorty filters
and supporting mods
So I'm not to sure if I already maxed out my little 408
Mostly track and little street blasts, thanks guys

I would think the spacer would be worth it. I've always heard that the spacer really helps.

The hvh isn't going to do anything for you since you're fuel injected.

on a Fuel Injected application it will respond to as much spacer as you can fit it. 4 hole spacers arent going to do anything more than a open spacer will do for you. A cheap 2" open spacer works really well.

A 4500 intake and tb would be worth more power than a spacer.

I don't think my little 408 would be up to the task. I just didn't know if a spacer would benefit me at all. I have two 408's going together, one is a solid lift and the other is hydraulic . Had to put the solid on hold because still waiting for my heads and intake to come back from a machine shop ( I really don't know who's machine shop ), its been almost 3 months

It is. I would bet 25hp over a 4150.
