Nice car. Sounds good. Just a fwiw you're limiting your potential power with those fuel injectors. They need to be bigger if you want to get to 450whp. Post the dyno sheet when you get the results.

I hope the 36s will work out. Some people say there big enough some say there not.

Well I guess the dyno will tell. From what I've seen is you'll pull hard till around mid rpm and flatline around 5k rpms. The cam and topend are capable of another 1000rpms(at least). You're going to go beyond 85% duty cycle. If you are running near stock fuel pressure(40#) they won't provide enough fuel. You can cheat and turn that up and gain some but that's a bandaid fix. That motor would really like a 60# inj imo. 36's are only good to around 450-500 flywheel hp. That is only going to get you to around 400-425 rwhp at best. What size pump are you using? Hope it works for you and if not you're just a few parts swap away for maximum performance. Best of luck and please post the results. We all are suckers for dyno sheets and pics lol.

Running 255lph in the tank and in line pump. Also I have 1/2 fuel line ran from the tank to a YouTube block to feed the rails. Adjustable. Fuel press regulator. I'll post the sheets.

So I can tune it. Cheaper.

Just my opinion,but I think a dominator is a bit much.
