Re: Most Powerful 305
There is a replacement for displacement. It is called RPM! And yes, it is expensive. But a 327 at 8,000 rpm is a FRIGGIN BLAST! I ran a cast 307 crank in a 350 block (large journal 327) with forged pistons and stock rods with Arp bolts. SCREAMER! Now for your 305, I say do it! I have never built a 350, not enough horsepower, not enough torque. I build 327's for max horsepower and rpm, and 400's for torque. I wouldn't build a 305 for bracket racing, but it would be cool to do if you want to. It's bracket racing, the final time does not really matter as long as you are consistent. Anyone think of that?

Re: Most Powerful 305
On a lighter note...
If someone has a V6, we'd say get a V8, because it's REALLY expensive to get a V6 as fast as a V8. Parts are rare, pricey, and don't do much.
If someone has a 305, bolt ons are fine, but once you need to bore the block, why only go .030"? Why not take the whole 1/4"? I like to have my pie and eat it too.
If you're there, that's the time when it's CHEAPEST to gain those extra 45-50 cubes. If you're picking an air cleaner, deciding instead to get a 350 block is EXPENSIVE. I'm not going to tell a guy who asks about a cam for his 305, to get a 350. But if he asks about pistons, rods, or a crank then...
If you're staring at a bare 305 block that needs a bore, you might as well splurge and spend say $100 for 45 cubes. Dollar for dollar it's hard to beat the amount of HP you'd get there eh?
When you're rebuilding a 350, if you need to replace the crank, that's when it's suggested to get a 383 crank. You pay $180 for an entry level 3.48" stroke crank, or roughly $190 for a 3.75" crank (383 crank). SO! When you need to replace the crank on your 350, that's when it's suggested to go 383. Heck I had my 350 crank turned for $120, later I found out $200 would have gotten me a stroker crank! Damn! I goofed. Live and learn.
However that mindset doesn't (usually) continue on to "why not get a 400?" "Why not get a big block?"
400 blocks are rare and or expensive. Same with big blocks. Most of us on here have most of the same ideals, go fast, spend little. Of course without throwing fuel economy, idle quality and reliability completely out the window.
So if you're going for MAX power, then a 400+ cid engine is peachy.
But if you're like the vast majority of us, you just want a good amount of power, and the most bang for your buck, hence the aforementioned suggestions of 350 or 383.
