Does any one know what intake would fit on a chevrolet 366 big block? I bought this engine cheap without doing any research and can't find a intake to fit. It's a 1987 big truck 366. Do you know if a 454 harmonic balancer and flywheel will work. Any help would be great!

·Stock, cast-iron jobber!
You are pretty much out of luck except for maybe a couple of aftermarket intakes b/c that motor is a tall deck one and you need a wide intake flanged manifold.
And to top it off they MAY be too big flow-wise for a 366 motor???
Oooop's, almost forgot!! You can buy aluminum spacers that fit between a regular intake and each head to adapt a standard intake to a tall deck motor!! BUT you probably may have to run a distributor with a movable collar b/c it's distributor is taller than a standard deck motor.

Are there not side spacers available to adapt a car intake to these high deck blocks? I think that I saw pictures somewhere a long time ago.

There are manifolds avail but most will be massive overkill like this one

Most Tall deck motors used are the 427 which are bored and stroked to 572-600+ CI and need those huge intakes
As for flywheel and balancer use any NON 454 or 4" stroke external balance types
Stock 427, 396 etc.. will work. You need a tall deck distributor or a MSD adjustable slip collar as the distance from the cam to intake is taller!!

I just pulled a distributor out of my 427 tall deck and compared it to a points-style distributor from a "normal" big block/small block.
The tall-deck distributor is the SAME length from the hold-down flange to the bottom of the distributor gear as the normal passenger-car distributor, although the bowl is taller to make room for the governor stuff.
You need a longer distributor ONLY if you use a car manifold with the side spacers. The original GM tall-deck manifold and most aftermarket performance tall-deck manifolds use a lower distributor pad so that the distributor is the same length even with the taller deck height. A regular manifold with the extra height of the side spacers will mean you need either a longer distributor, or you can modify a normal distributor housing and add a slip-collar to achieve a longer distributor. The slip-collar is about $13 from Moroso, I think. You'll need a lathe to carve the housing, though.
The original tall-deck manifold is not a terrible piece, the runner sizes and shape seem to be OK. They are set up for a square-bore Holley, and perhaps you would need to open up the four holes for the throttle plates. The cast-iron tall deck manifold is very heavy, though!

Good point, I forgot the stock Tall deck motors have the recessed Dist pad.
Also dont forget the Stock tall deck heads are pretty lame. And the stock giant 4 ring pistons are very heavy. Also the 366 has a very small bore, those motors are universially considered junk and the only good part is the crank.
The 427 is only good for the block and crank, and the forged crank is usually sold off and a big stroker crank is used.
