I'm to old and slow for focusing on ET, MPH on the other hand takes alot less skill, and is a way better judge of "actual" power
As for a blower, with my little 223 228 114, 2800 stall and a HTV2300 on the old Gen 3, my car has brilliant street manners and is actually more fuel efficient than when it was stock, well around town it's averaging about 350km per tank, hwy is over 600km a tank, it does drink like a fish when your up it though, but that's to be expected, it also has a nice loapy idle
A thing to remember is what you use the car for, if it's a daily or you use it alot, a big lumpy stick can turn it into a pig and you will end up hating on it, for multiple reasons, especially if you get stuck in traffic or your better half drives it sometimes, this is where a blower rules the world, they make smooth effortless power from idle
If, on the other hand it's a club car, drag car or Sunday car then all bets are off, CNC the heads, a monster cam and big stall that shakes rattles and rolls, and makes power up top, IMO nothing in the world sounds as good as a big NA V8 revving it's guts out
I only say this as I've built cars that I daily to the point of hating them as a daily, my current old girl is a VX SS that I got for a cool old daily, and whilst it goes like a raped ape on request, it is a pleasure to drive around town, even when stuck in the M5 tunnel doing 10kph
Have fun with the build, and if you can justify it, trust in the workshop, these are old cars and have been done to death, a good workshop and tuner should be able to give you exactly what you want
MOST IMPORTANTLY: DON'T LISTEN TO ME, I'M AN OVEROPINIONATED ARSEHOLE
