hello, new to the board, just pulled out a 305 tbi from a 91 z28 and found out the block was cracked, just wondering if anyone has a 305 block for a roller motor, or know anyone that has one, please e-mail me and let me know, thanks.

like's been said before you're spending you money to buy the bullets to shoot yourself in the foot with
well i supose its possible, but we'll see where it goes

If you really want to build up a 305, by all means do. You can pump in some pretty decent horsepower, just not as much as a 350 or a 383 or a...
But i would have to agree with what ede said, your just buying the bullets. Just my 02

i understand what you are saying, i dont know, just something different i guess.

If you want to build something different, seeing as 350s and 383s are common why not build a 400? Theres all kinds of combos you can throw together (strokers, destrokers if you want to get really different) the cheapest of wich would be a 406. If your planing on building a power house with a 305 your only going to be disapointed in the end.
we'll see i guess, theres always time to build another...better

305s have a couple of strikes against them as a performance motor.
1.) small bore-shrouds the valves and doesn't give a big surface area to push down on, limiting power potential.
2.) lightweight parts - most 305s have lightweight blocks and cranks compared to a 350, even though they share a stroke.
3.) heads - mainly due to the small bore, most 2.02/1.60 heads won't work on a 305.
All that being said there are plenty of people that build them and run decent times with them. If your goals are to run low 13s or faster then you are probably wasting your time, and money on a 305. If all you want is decent street performance then there's no reason not to build a 305.
If you're shopping for a block already you will be bucks ahead to just pick up a 350 though...
