like the title says--looking to build a very reliable streetable 400 using the stock looking tpi that i already have.will put everything from my 350 into this(see sig)am currently porting the plenum and have a new edelbrock base and asm large tube runners.
my question is this--will the supercharger make up for the lack of high rpm breathing that i will have using close to the stock setup?should i install a larger tb.58mm?
looking for approx 500hp with loads of torque
will a setup like this work?

Being supercharged, you won’t need too much to make 500hp. To be honest, the long tube runners and ported aftermarket base are very good to 5800-6000rpm. Unless you want to be spinning up in the 6500-7000rpm range, stay with the long tube setup. I mean you are looking for a streetable motor. We’ve even gotten a fully ported Superram to make power up past 6200rpm. Most definitely though, go with the 58mm throttle body. You’ve got everything else for a good streetable motor. What cam do you plan on using?
