Re: 305 forged rotating ?
please stop
on the other thread you also asked about 1.6 rr's
do a search on this site about trying to extract power from the 305. At the end of the day, you need to get rid of the heads, valve train and induction system. None of them are a good foundation from which to build. many will tell you to go find a 350 but it's not the displacement that's the issue, it's just that the LO3 was not designed for performance and the cost/benefit of trying to make it into a performance engine just doesn't work. A 350 isn't a magic bullet either because the majority of production 350's were also dogs that need induction and top end changes. Translated, you're going to have to spend money.
You need to retrofit the entire engine and that is when you come to the decision that if you have to do all of that work and spend money, why not do it with 45 additional cubic inches. Unlike the 5.0 from the similar year Fords, you get choices from Chevy because the small block is plentiful and inexpensive thus why many just go to a 350 block.
So, either slap on some headers and an open air element and be satisified or prepare for a repower. To do it correctly with a well rebuilt engine isn't cheap. Yes, you could use a junk yard engine (craigslist engine) and have junk yard quality.
search the site, all of the questions you will think of have been answered countless times because the cars are over 20 years old. There's a wealth of information on this site.

Re: 305 forged rotating ?
The 305 and 350 internals are the same except the pistons.
You can chose any 305/350 rotating assembly with 305 pistons and have it balanced.
cnc-motorsports.com will put together any parts of your choice and balance the assemly.
