I would say probably 210-225, It will have a small journal steel crank and it's only worth what you want to pay for it.....most guys wouldn't give $100 for it unless they were building a 327 specific car. Great little engine though.

The only model 327 that fits your 375 hp criteria is the '66-67 327 365 hp Rochester Mechanical Fuel Injection model from a Corvette. Prepare to spring $10,000+ loose if you actually want one of these, they are rare as hen's teeth.

Virtually any 327 you will find will be in the 210-300 hp level, all the rest(320-360 hp) are Corvette or High Performance SS versions.

I have to ask why you specifically want a 327?? A good 350 or 383 stroker is a better more powerful engine.

327's used in trucks, buses, etc. mostly had the 1.72" valve heads- not at all what you want for performance. You'd be way ahead of the game by looking for a '96-up 5.7L longblock w/the 062 or 904 casting Vortec heads, IMO. This engine has the 1 piece rear main seal and a roller cam/lifters.

Next in line would be an '86-up SBC 350 w/the roller cam and lifters as a shortblock, then source the heads from elsewhere- aftermarket if your budget allows.

Not all '86-up blocks will have a roller cam, but most (NOT ALL!) will have the drilled and tapped bosses to accept the 'spider' (roller lifter retainer), 'dogbones' (roller lifter link bars), and will have the provision for a cam retainer plate- even if they came from the factory w/a flat tappet cam. But I would definitely hold out for an engine that had a roller cam already in it so you'd get the parts required to run the roller cam rather than having to go elsewhere to find them.

HERE is a thread that has info on what blocks to look for if you want to run a factory roller cam.

Tylerwater...You can take any 327 small journal block and crank, like the $400 dollar one you're looking at and build it into a high perf. engine. You don't have to have an Original "Corvette" engine because the blocks were all the same. Actually the highest hp 327's were the 64/65 375 hp FI engines but who knows what they really were. So something to think about and as Cobalt eluded to about the heads, also intake manifold, cam, rods, blah, blah are no good for your hp needs. You'd be paying $400 for a block, crank and some sheet metal....

IMHO $400 is too much for that 327. You would be dollars ahead building a 350.

Then do as Cobalt suggested. Find a 1996 and up Vortec 350. Everything you`ll need for a performance platform is there.

What makes you think a 327 would be any different? It takes more than HP to make a car get up and go. Put 400HP in front of the wrong transmission and rear end and it will be a bigger dog than a 200HP engine with the right transmission and gears.

I had several 327's when I was a kid, they're not "magic". The fast street 327's back then were turning some seriously steep gears out back usually 4.56 to 5.38's. THAT'S where the instant throttle response came from.

The bus 327 was a low compression version and even though it has low miles they were probably hard miles. A 327 had to work pretty hard to move a bus. Most Vette 327's were the same 250 and 300 HP versions found in Mom's Impala, not the Special High Performance versions
