knows how to make 318s sing, for low money.
I know how to make a stock 318 sing by coordinating add-ons.But I'll never ever up-cam a stock 8/1 teener again, ever.
You already have what it takes to have fun with,the 3.91s. But the 3800 won't leave much Rs to work with, as the stocker is done around 4800.
Your case is kindof special, cuz you wouldn't care about the lazy bottom-end. To that end you could install a Solid flat tappet cam, and get some torque back.

Say your car scales at 3200# car and driver;and say you would be happy with a 12.9;
Well,my charts don't list street chassis, so I have to aim a second faster,on the SS charts and when I do,I get a power requirement of 350 hp@3200lbs now with a street chassis. This may trap at 108. But may ET just into the 12s. (And if you spend a boatload of money on it, minimum SS ET is about 12.2)
350hp is doable with any SBM, but with a 318 at 8/1Scr, it's gonna take a very rowdy cam, and maybe it will be a PITA around town, and suck a lotta gas while doing it, and so,it may end up parked for a lot of the time..
The 360 is a much better starting point.

But my favorite thing is to just throw something fun together for the street, and let it trap what it traps. From the trapspeed we can back-calculate the minimum ET, and that's always been good enough for me. And in that case, I'd leave that 3800 in the box,lol.
