IMO

Some people are die hard LT1 fans and just like some like carbs over F.I. I'm a simplistic person when it comes to cars, and i do things that are economically sound and something i can do the work to. We don't have a lt1 tuner here on this island. We have to send away for tunes like Birdracing did, I still may need a tune because of a rear gear chance so it'll be interesting what a tune will net me in e.t's...

I just got the car last year and I already have some things I wanna change, throttle body bypass, tubular control arms, panhard bar, LCARBS, and a set of good stickys.

I'll post my results and we'll see what it does...just need the damn snow to melt... i wish i lived down south.
aluminum heads help but reverse cooling has a bigger effect.

Just for reference sake, in Toronto at Cayuga .. Bone stock 97 ss with totl ran 13.9-14.0 various times of the year. Over a hundred passes or so. Paper filter.. Factory bfg tires at 38 psi.. Nothing touched.

Driven to englishtown in October.. Went 13.5@105 with k@n filter and edelbrock shitty .. I mean shorty headers.

Power windows, locks, mirrors, cd, etc. 0 weight reduction , no electric water pump,no tune, no underdrive pulley, no FPR. It's very possible without even full bolt ons. The bolt on record is 11.54, by the way. Don't be discouraged by the pessimistic, OP.
Thats pretty impressive with the little modes you have.

mpe331lx, that is a very fast et for a bone stock lt1! The power of a m6! Gotta love those 6 speeds.
