which would you do in this situation? so i have a forged rods and low CR pistons in a 347 ls1, it ended up spinning rod bearings so the crank and rods are trash, pistons are still good and probably have 2500 miles on them.
my original thoughts was buy new forged rods and new factory crank and get it back together as it was (and use a diff engine builder this time lol) well after pricing it out i could pay just a few hundred more and buy a whole 383 rotating assembly and turn it into a 383 and then sell the pistons to recoupe some money
if u had this engine/situation which would u do, rebuild it as a 347 or order a 383 rotating assembly and build a 383 out of it?
this is going to be a street driven turbo car thats occasionally used for 1/4 mile and road race courses

the rod bearings spun cause the guy who put the rods on mixed all the caps on then if i was to guess didnt torque correctly cause the rod bolts all broke loose with differnt tightness, and the turbo specs are 1.0ar exhaust and .72 comp, master powers 76
for some reason i just remember hearing 383s arnt good for turbos but never got a solid answer why, id love to have the low end for street driving/non boost driving.

Saying a 383 ci engine isn't good for boost is incorrect unless you get there by boring the engine and making thin sleeves. Id go 383 and a tc 76/75. It will be right around the same size as your current and work better on the 383.
Most ideal would be twins or a single t6 but if your not shooting for the stars here you don't need it.

ight, yeah i didnt quite get why a 383 would be bad, wsnt sure if it was crank stroke or what but the sleeve thing makes sense, with that being said
do i send the block out to get bored by a machine shop or do i need new sleeves? whats the "correct" way to make it a 383
and what would my current turbo do, just not push that well up top and choke out the engine? i want something thats as close to instant spool per say as i can, again this isnt a drag car i sit and spool then go so

You can get a Stroker kit for the ls1 and make it a 382 or 3 with out much of a bore. It will spool pretty instant with yours and a tc76/75, or a precision 76. Just your turbo is going to have a ton more pressure and drop in power probably around 5k. Go bigger it will be safer and make more power

i thought about if i made the effort to have a 383 to probably get a custom specd cam
power goals on 93 are a reliable and healthy 600-700 rwhp,
im probably at 500rwhp on my current 5.3 with 243 heads and epp cam on 12 psi
when the 347 were discussing spun bearings a $500 5.3 was the cheapest fix to get car back on road so thats what i got now
the extra low end of a 383 is kinda what i was lookin for too but mainly made this to talk about my options and see what other knowledgeable people (you all lol) thought whould be a good way to go
