You probably have all the tools to build an engine, if not the price of the tools and measuring devices would offset any time and energy put in yourself.

You can build your own but you would have to get good deals on good parts.

I spent 15 grand on parts and some minor machine work for my 427ci small block. All good part and I had all the time in the world to put it together. A crate engine is probably put together in a day or so by someone with questionable skills.

I could have bought a crate engine for about the same but the description of some of the parts was sketchy.

If you build it yourself you know all the measurements and clearances, just like blue printing an engine.

I would like to add that the Engine I posted above is absolutely bulletproof.....will easily handle a 400 shot of NOS or a 100 mile trip....
I always thought building engines with more stroke than this is kinda worthless unless you are class racing.....

Once everything is machined it is a simple matter of measuring it up and putting it together.

and you need 800hp on the street?

500+ is a real big number,

new cars with 600+ have ABS,traction controls and a bunch more so they can be driven ,

Need and want are two different things. 1975's 165 horse was enough to move the car along and cruise at highway speeds, but what fun is that?

You don't need computers to drive a car with big power, that takes skill and the use of one's brain. I will admit some people are lacking both though.

All... the object is to test my skills (& have fun) building a high HP BB engine. I'm not expecting to be Mario Andretti on the street. I want to build a high torque BB just for fun... no aspirations of taking on the world. I get my kicks in the building part, not the driving part. After I build it, I'll probably drive it to get groceries. RE: the rest of the car (suspension, trans, diff).... that can come next. Baby steps. It looks like the recipe is more cubes, a forged stroker crank, and a static compression ratio at or above 11 : 1. Is there any inherent benefit to a Roller Cam?

I'm building a 496, 10.5:1 compression so I can run pump gas, all forged lower end, and a roller top end with aluminum heads. Bulletproof HD stuff. I'm looking at reliability as much as anything. And should have more than enough torque to break everything else.

Yes, especially when you are driving to the track.

All of that still doesn't stop Hellcat owners from running into walls and tree's.
It's all about the driver and his/her brain.

Default fun on the street

I've got a nice 10.5 - 1 496 with a mild hydraulic cam that is speced 569 hp and 525 trq Even at that level traction is at a premium

I'm a bit short of $$ right now so $5250 gets the motor, carb to pan, all fresh, never run

good street motor, scat 4.25 crank and rods, forged pistons, square port alum heads (pro comp), roller rockers, holley 850 DP, high flow pump, hydrualic cam.

If you want to turn it up over 600 hp, I have a solid roller that will allow it to rev over 7k and

polished high rise intake, nice stuff!!!

Back to OP,

I've see the stroker short block kits go for around 4-5k unassembled with some nice parts that will make that 800 you need with the right heads

Or I have a nice M3 procharger that will allow you to do it with the little 496 and have a very torquey and under stressed combo.

I've gone turbo LS of late, so I need to clear out the BB stuff
