Block HP limit?

[thojoewen86]

Im looking to buy a new block for a stroker build but I was hoping to start with a used block. I found a FRPP 306 block for a good price but wil that be any stronger than the stock one I have? I also found a 408 but the block is out of an old 1970 van, am I just better off stick to building the stock block I already have? I am hoping to be able to handle 500hp with the nitrous when the car is all said and done but Im on a budget. Any help is appreciated.

i believe the stock block is good for ~500 hp....and figure thats the average so give or take about 50hp either way. i think its generally considered a good idea to go to a dart block or something of the likes if your gonna break 500

500hp....then they crack, split ect...

wouldn't even 450 on a stock block be considered borrowed time?

I think even 450 horses your gettin close to the limit. Figure like 450 rwhp.
