Im still putting the parts together for my 408. Going with a budget build. patriot Freedom 185 heads, 95 roller block, probe stroker kit, Eddy Air gap intake, long tube headers, 2.5" x-over exhaust. I am waiting till the engine is actually assembled before I decide on my final carb/cam pieces. I have 650 and 750 carbs waiting in the wings but I'm still researching the best cam to unlock the HP. I have taken out the vaccuum system for the headlights and am replacing it with the electrical swap and since I dont have power brakes I can go a little heavier on the cam if I want. I have a 9 inch with a locking 4:11 waiting to go in once the swap is done.
If I can get anywheres close to 400 rwhp with this setup I'll be tickled pink. More than enough for my purposes.
Your engine sounds awesome. Gives me hope that I am on the right track
