Can you put lt1 heads on a 350 block?
The long answer is yes, the short answer is an emphatic NO.
They will physically bolt up, but the water passages don’t line up.

How much power can a stock 350 crank handle?
For small-blocks, a safe limit for a cast crank is 500 hp and a maximum of 6,500 rpm. With big-blocks, their bigger mains will handle 650 hp. We’ve seen cast cranks in turbo motors take over 2,000 hp, but we don’t recommend it. These days, 4340 is the standard for forged cranks.

Will lt1 heads fit a 350 Vortec?
Not Considered a Senior Member And no, LT1 heads will not interchange on to Vortec blocks or any of the classic small blocks for that matter. Why is because the LT1 is reverse cooled. While LT1 heads will bolt on the classic small blocks, none of the coolant ports line up.
Why is a 327 better than a 350?
A 327 with it’s shorter stroke would need shorter gears so it can GET to its revs, where a 350, with its slightly longer stroke and more torque output will pull a little taller gear than the 327 will.
