Mike I was wondering what heads on the 69 Windsor block were making 700 hp. But my 8.2 block makes 700hp with help of that bottle In the trunk.

If I was going max effort with nice parts I would be using a dart block. Just my opinion.

You CAN make good power with a stock block...  it's just always wise to make big n/a power with a stock block when a Dart SHP is available. 

For a stock block, you can build a solid 6500 rpm, 11 to 1, 600 hp 408 on a fairly decent budget, then safely hit it with up to 200hp of nitrous...  and still have a decent service life.  Exceeding these limits drastically limits service life, and your entire investment can go 'boom' rather easily. 

Stock Block Survival Tips:
6500 rpm limit
11:1 limit if using nitrous
Don't get greedy with tune and timing

Good Luck!

My thoughts was if you are using max effort highports , star vacuum pump , forged internals , and high end Pistons.  Dart SHP block is good insurance. I know what I have in my highport 240 and Ross pistons and forged internals. The block was a cheap part.  It never said it could t be done. Good Luck.

it is good insurance but its not a cheap part

200$ for the stock block versus a couple thousand
i am no wealthy man'

if you can afford it hell yes put insurance wherever you can
hence the star vac pump instead of ...basically any other ppump

interested to see how your build turns out it most likely will be complete before mine

i just like NA cars

but my thoughts on the nitrous with the stock blocks

it would definetely be cheaper to go as fast as i am with the NA smallblock


i like things simple
so im spending more for simplicity

il never be the fastest thing in the world but i for sure wont be the slowest, and less things to worry about (at least i hope)

What Mike is suggesting is not Max Effort. whe. You said that I was thinking get of what my top end cost 240highports, Crower shaft rockers , Crane Ultra solid roller Lifters,roller cam cost. If it were me I  was going to use stock block I would be using 192 high ports , Mech flat tappet cam ,and Woodys cast crank 408 kit and have some fun.  If it brakes the block you will not suffer as big of loss.. That's just my 2 cents. My engine is up and running am upgrading reer end from Detroit locker and 31 spline axles to spool and 35 spline axles. Also need some more safety equipment to go this fast.good luck.
