hey guys i have a 87 iroc 350 and i took it to some guy to get finish and he told me that the motor is locked up cause my dumb *** let it sit for 3 month with the heads off and i guess moisture got into the cylinder walls and messed it up my question is can i just get any 350 block and use that i mean i know the heads are different cause the center bolt valve covers but i wanna know if i can get any motor someone told me to jsut switch it to carb but i dont know what to do i mean now that i need a motor im gonna def beef it up since its gonna be out but i just wanna kno if i can get any 350 block any help would be great im trying to do this asap thanks

 

as long as its a 350 block you should be able to use it. as far as i know

 

if you need to re-install your TPI setup..you would need a 86 & later Roller cam block...
if your keeping your 1 piece crank..you will need a 86 & later block
if you convert to a carb setup.. the heads are not so good.. but you can get any 350 block

 

i mean any 350 block i mean i found one on craigslist for 450 its a 4 bolt main and he said it was out of a 70 chevelle i just dont kno if its the same

 

what do you mean i kno my motor has a stock roller cam in it but i mean i cant just get any 350 and put a roller cam in it cause if i get a motor im gonna make it a 383 stroker but i wanna keep the tpi i just dont kno what i need to do and i dont kno if its jst easier to change to carb

 

i also wanted to kno can i just reuse my block or na i mean it had alil bit of surface rust on the cylinder wall on the drivers side thats eat i just didnt kno if theres a way to reuse it or should i get another motor

 

if the rust is not to bad you could re-hone the block and do a re-ring
450.00 for a bare block I would not buy it

I know you have a 86 & later block
but you will not be able to install that roller cam in a 85 & earlier block

 

In that case just make your engine into a 383 and you don't have to buy a new block or worry about the cam type.
Boring 30 over will get rid of the surface rust in the bores

 

383 on a 2 bolt main???
it would cost a Min of 250.00 to install 4 bolt mains

 

i guess my motor is a 2 bolt main i dont know but i cant make it a 383 without it being a 4 bolt main i have no clue its prob a dumb question

 

so i can just take my block out and do that i didnt kno i thought i needed a new block i just was gonna make it a 383 cuase i already have the motor out so i mine as well dump the money into now and how much does it usually cost for a shop to make it into a 383

 

yes you could make your current block a 383
i would not recommend that... with a 2 bolt main.. with a longer crank stroke

 

would it be bad if i did that or na and can i use any 4 bolt main block or na and someone said if i do a 383 stroker kit i shouldnt use my stock heads can i use vortec or do i have to get aluminum ones im tight on money

 

It is ALMOST the same. The oil dipstick is more than likely be on the driverside. If the block is that old, then you know for a fact that it may have significant wear and tear. Before you buy it, ask for the casting numbers. This way you can verify the size of the block. Then have the guy get a measurement of the inside diameter cylinder walls. Look around to see the maximum wear on the inside of the cylinder walls.

 

to make a 383 flow... I would look at Patriot heads or similar <> very good price
sell or trade your block... I went to a machine shop.. and traded blocks they just said I need to dis-assemble
a 350 M block.. is very heavy duty thicker webbing and casting
and 4 bolt main ...you would need retro roller lifters if you want to keep a roller cam
