Does anyone know how much power and torque the standard L98 86" connecting rods and crankshaft can handle?
I have forged pistons but otherwise standard bottom end and now run 6 psi boost 403hp 442 ft lbs.
I was wondering if I could increase the boost pressure without exploding the engine...

I think it is going to be mostly about managing detonation. What are you doing for engine management? If you've got a sane spark and fuel map you've got a lot more to go. I got mine up to a bit over 700ftlbs at the wheels on the dyno before the transmission started slipping so we backed it off. Torque is what kills engines not power. I left it at its 550ftlbs at the wheels setting and have driven it that way ever since, including beating on it at autox and lots of street driving having fun
edit I see your signature -- if your IATs are staying good I would definitely mess with a smaller pulley. you could post a screenshot of your spark map in tunerstudio as well if you'd like a review. You may end up needing a new clutch

So you're in Kali... Only 2 SC kits that have a carb eo number. The Paxton SN series with water injection (BTW I'm selling my previous SN2000) or the Procharger P600b with intercooler. I have a 383 with a super ram intake that got 5-6 psi with the paxton and then 15psi with the procharger. With (no intercooler-test running it) 15psi the cheaper forged pistons I had came apart-now building another 383 with 2618 forged pistons, AFR 195 heads have eo number also. As for the cam just can't go too big-make sure it doesn't lope at idle and then have to tune it for clean at the tailpipe. Anything that can be seen has to have an eo number. At least OBD1 doesn't get scanned for factory checksum like OBD2!!
