Well my 318 started to knock and once again I was facing an oncoming Summer of missing out on cruises, car shows, and racing. My planned slow conversion from show pony to street/strip monster had taken a frantic leap forward leaving my meager toy budget in a state of crisis.

I figured, if I'm going to have to have an engine built, it's time to go all in. I spent hours of days scouring the internet looking at crate motors I can't afford and made lists of the parts I could scrimp and save for in hopes I could have a decent engine by 2025...

I found a few core big blocks ranging from $400-$1500 in need of rebuilding before they could be used. Figure machine work would cost a minimum $1500 and what the heck, I might as well stroke the short block for another $2000-$3000... and a TrickFlow top end kit for $4000 more, of course that doesn't include roller lifters, ignition system, water pump, fuel pump...you get the idea.

Without using credit cards I could only afford half of the above

So disheartened, I slogged forward and contacted a local engine builder in hopes of making him laugh and possibly able to buy a descent lunch with the pittance of my offerings when things took one hell of a turn!

Just so happens a previous customer mentioned selling an engine he recently built. Granted it's a mud racing engine with four passes, but it's almost a pump gas motor. Shocked by his casual tone and lack of mockery, I bought it. I found impulse buys have always worked out in my favor despite what my wife, mother, and dog say.

So here are the details: sonic checked 400 bored .035 over, 440 source 512 stroker kit, stealth heads, estimated 10.5 compression ratio, tunnel ram intake with twin Predator carbs (my uncle ran them on his jet boat back in the day) and a custom grind Howard's Roller cam:

SOOOOOOOO,

What kind of hp do you think it will make? I will probably switch to a single plane intake. This won't see much daily use. My reasoning is the short block and heads alone are worth as much as I spent.
 
That sounds like you were in the right place at the right time. You will have to locate a big block transmission case and have the internals swapped out at minimum. Maybe you will luck out again and find a built transmission too. I'm sure that the engine will make good power with a single plane intake but I couldn't tell you how much. Someone will chime in I'm sure. Good luck with your project.

Thanks, the guy is throwing in a 727 core for free. Have some bonus money coming and looking at the Cope Racing Transmissions, thinking their pro-race transmission. I have time before I can get into the uninsulated unheated garage and -8 degree temps.

I'm also going to rebuild my 318 myself to gain some skills. I've done bolt on stuff but never anything that big. My friend from work Victor built a hobby shop. He rebuilds WRXs and has a couple S2000s.
