Valve Drop
Dropped a valve on my rebuild. Head & block are finished. I don’t want to re-sleeve. going with new block.
looking into LSX iron block as opposed to staying with aluminum. Although I watch Reese proven motorsports YouTube channel they have good results staying with the aluminum blocks and superchargers . near future I will super charge after recover from two Engine builds.
my question:
the added hundred pounds on my front end how much will that upset my front / rear weight distribution. Slightly or noticeable? if noticeable how do I correct that? Coil overs or ? Thank you guys for the input ahead of time.

If manual car on a base car (Fe1 manual), swap over to front trans spring for auto trans (FE1 for auto trans).
If auto, then swap over to new spring up for automatic (Fe1 to Fe2)
Hence auto cars have about 100lb more in the front weight from the auto trans than the manual cars, and there are two different springs in the Fe1, Fe2 and Fe3 front trans springs for this.

I added quite a bit of weight from twin turbos, dual intercoolers etc which was fairly significant weight gain over the front....quite a bit more than 100lbs I'd imagine.
The added weight dropped the hight a bit in the front causing additional issues up driveways via impact to the lower radiator support. Eventually I remedied this with a set of coil-overs allowing me to easily adjust ride-height and rake to desired settings and corner weight.
I DID give up quite a bit of comfort (over leaf/shock) but it's not a daily driver.
The additional weight didn't seem to affect the handling once alligned/corner weighted and proper sticky tire (R888R's). I also upgraded the breaks to allow for the additional weight and better breaking.
I've never timed/tracked the car so I couldn't give you exact specifics.
Like Dano stated, a stiffer leaf (and upgraded shock if not already installed) will most likely be all that's needed for only an additional 100lbs.
