Good evening, this is my first post as a new member on Moparts.

I am new to the Gen 3 Hemi platform and starting to gather parts for a new build. I am looking to build a 426 stroker based on a 6.1 block. I have a Molnar 4.080 crank, rods with .866 pins, Milodon pan, pickup, windage tray and oil pump. I have new apache heads as well. I am looking to build a carbureted engine in the 650hp plus range.


Can anyone tell me if the Edelbrock 7528 dual quad intake for early 5.7 heads can be adapted to apache heads? If so, would it be a serious bottleneck for the output I am looking for? I ask because I have a new one in the box. If it can't be made to work, is the Modman worth looking at for dual quads? I have seen mixed reviews on these, specifically being very poor on carb signal due to large plenum, as well as high rpm oriented due to short runners. If neither of these dual quads is actually a viable option with good results, I had looked at the Arrow/Prefix intake for a single carb.

What header size is recommended?

Camshaft?

I have many questions and know little of the Gen 3 Hemi at this point. I currently runa 408 W2 combo with a tunnel ram. Car is a mostly hot street machine that will also see strip action. Any input appreciated. The car is a 69 Swinger, 18 spline 4 speed, Gear Vendors, 4.10 geared Dana 60, and aluminum flywheel.

There is nothing wrong with my current combo, I'm just looking to kick it up a notch.

Holley Hi-RAM with dual quad top or Prefix Drag Pak copy.
1 7/8 headers
Others can recommend a cam, probably custom.
Sounds like a good combo and welcome to the board.

Thanks very much for the welcome message!

As for the HI-RAM or Drag Pak intake, I would be unable to use as they won't fit under my hood. I currently have my tunnel ram W2 engine hidden under a six pack scoop. I would consider a Hemi scoop for more clearance. I would take a slightly lesser manifold over bare carbs sticking out of the hood.
