that's essentially what it would end up being but with an iron block instead of an aluminum block; saves you the cost and trouble of locating a different block

 

lots of ppl have bored the 5.3 out, with new internals and make a 346

 

Theres quite a few around Ive built 2 iron ls1s, one was forged, fixin to start on an iron 383

 

no steal steal your thread..but i am building a 08 5.3 with a TVS1900 ARH 1 7/8w/cat and 224/230 114 cam DOD delete. The kit i got cam with 42lb injectors and i was wondering what i should buy first...starting to run low on funds after buy everything...

meth kit or 60lb injectors....and i still need to get a higher stall converter going with Circle D

 

I did'nt mean to word it that way of no one ever boring a 5.3. I've just seen were most people ditch the 5.3 and go with the 6.0. Anyways, I'm looking at the two stroker kits one says 346 and the other a 383. How far can i go on the 5.3 block bore and stroke wise? Also I am going to port and polish the heads or would it be better to run a different set of heads. I am still going to run the mp112, may uprade to the tvs later.

 

the 346 is bore only, the 383 is bore and stroke

 

I think that if you are planning to build a 383, you should consider a larger blower than the 112. The 122 or a TVS series would be better suited for the larger cubes.

Just my opinion.

 

Will the 112 work with a bore to 346?

 

it will work fine on either engine. If that's what you have that's what you should use unless you want to spend the $$ upgrading the blower as well.

 

I would use the 112 on a 346.
