I dont know if u have already gotten the LT1 engine and stuff to go with it but i would suggest going for an LS1.
I have owned a 96 firebird formula with the LT1 engine. while the engine's performance is nice to have for a daily driver, 320ish torque is lots of fun and the low end torque is what makes it really fun.
However if u do go with the LT1 make sure u really get a good distributor because theyre known to **** and go out. mine had 122k miles and it had to be replaced, just looking to try and help u out with not having to go all the way down to the distributor, it sucks. supposedly MSD makes a good distributor but idk i got rid of mine shortly after changing the distributor.
not to mention changing plugs is terrible. LS1 has coil packs!
