Plan to forge out my bottom end with an L8T crank and a piston/rod kit from tsp, LT4 fueling system, E85, headers, and prep the valvetrain for boost. I don't plan to get intake/tb/manifold because I eventually plan to get a supercharger and I don't want to buy parts just to sell them haha.
Aiming for ~500rwhp at my altitude(5500+ ft) but we'll see. Aiming for reliability over squeezing the last ounce of power out of my car.
I've been following your build for a while and I'm sure you've already state why, but just curious as to why you're staying with the LT4 blower instead of going for something bigger with the HP you're aiming for? Regardless, your build is one of the builds that has me flip flopping between a bigger blower or the LT4 blower for my needs.

Nice in regards to your planned build. What cam are you going with? I did the EL7 cam and my forged NA build did 527rwhp without E85. You should be higher with the E I think then my 527. Also do the lower compression pistons for your build because u want to do a SC later. My mistake is I purchased Diamond piston at stock comparison and that hurt my higher HP because I can’t add as much timing. I thought I was going to stay NA but the SC bug bit me. I got a deal with the conversion kit and a great deal on a new SC 1.7 SC from a shop that I had traded some Nitrous parts with is the reason I got the stock blower. The 1.7 packs a instant hit and especially on a manual and true it can’t make as much power as the higher aftermarket SC. Do i regret it, no. Because I really can’t imagine driving 1000 plus car on the street, ask Josh. It’s a handful.
