How much hp can a stock 95 3.8 block take. Where can you find supercoupe blocks

 

they are the same and around 500 HP

 

except for poor water passage design the 94-95 block is strong.

if i was planning on alot of boost or nitrous i would get a 97+ block

01+ blocks have reall beefy main webbing and are probably the strongest. 4.2L girdled truck blocks are quite strong too

Matt Neuharth is running 600rwhp on a production singleport block and IMO the block is good for 1000rwhp but would benefit from braces acrossed the lifter valley to prevent the chance of block splitting
