Fast 4150

The 317’s are not milled, I had the intention of using my turbo setup on this engine but I’m going nitrous crazy.
It will be nice if I get that improvement, or even more when I get te darts on. I’m going to make the dyno comparison between the 2 setup.

That’s why I’m going with this TB, he mention this setup and I've been searching a lot about it and now I’m trying to find the 4150 that flow the most, I don't want to go with a 4500 since I'll spend more on the adapter and later on I’ll be swapping all the nitrous setup to a Trans Am I just bought some months ago and don’t want to cut too much to make it fit.

I would say 456 gears would be your best bet with a 4000 converter. That cam will like compression which is why I ask. An easy fix would be 243's since they flow the same and compression is 66cc I think.
I had made a post here in which I ran an 11.05 at 122mph with a 150 shot, I had just ran a 12.9 @ 106 before that NA on 7 cylinders. I took the truck 2 weeks ago and try it out after I fix it and just got to run ones NA and it improve a lot 12.32 @ 111mph with a 1.87 60's now I want to test the 150 again.
The heads I already have the Darts which were ported by Brain Tooley, he did an awesome job can't wait to put them on, they are at 62cc so it should help with the compression.
