tall deck 366 Chevy

[woz]

This engine normally carries the "boat anchor" designation, but does the 366 tall deck truck engine, with non-stock cylinder heads, rods, pistons, induction etc. warrant any consideration for a big-block "C" engine?

Any thoughts from experienced folks would be appreciated.

Thanks, Woz

I have that possibility-- I have a Bryant 3.1 crank---I am looking at a LS motor

No reason not to use a 366 other than it has a small bore under 4". The 427 tall has a 4.250 bore allowing a lot more stroke without hurting rod angle by using a long rod. Theres also plenty of direct intake options for them.

A 348 crankshaft with a 4.25 bore is another good combination . 369 ci and less valve shrouding . Requires piggybacked main bearing .

Woz-
What class are you wanting to run? As Sparky alluded to, a stock block & crank 6.0L LS with
good rods/pistons and the (recommended for rectangle port) .030" overbore will make gobs of
power for a very small investment. You'll still be at the top end of "C" with 370CI and can set it
up for Classic with a carb & front mount distributor if you so choose. I know a lot of people would
rather go old school with motor choices, but these things are cheap, plentiful and strong.

hmmmm....great minds think alike??  use the 366 and that way, if you want to step up to  A or B ? the mounts etc. are already where they need to be

[woz]

Thanks for the advice regarding the 366 TD engine.

The 427 TD is also available but a few $$$ more.

A gentlemen around here has several of the engines and the price is right.

I think Varni, Walsh & Cuzac tried that in their roadster with out too much success but maybe I just didn't see it when it ran good or have the wrong info on it

[floydjer]

Well heck....Alot of people put the engine behind them long before Garlits did at that didn`t work either.

No problem with an LS motor going to A or B either.  There are 500 cu. in. combos available now.  The 366 might be cheap but some of the most expensive projects are the ones that got started with some cheap or free parts  .  The LS platform is going to continue to grow. 

If you are going to end up blown lots of cu. in. might not be the best scenario anyway (ref. Speed Demon).  If we were to build another AA motor it would be at the bottom of the cu. in. size for the engine class break.  An A might be close to being a B.  From there down I go close to max. allowable size.  The reason being that it would be easier to find less expensive turbos that would still do the job.  Those big motors need some mighty expensive turbos to make them work,

Hell, "D" as well. Know of several guys making over 1,000HP using the "lowly" 4.8 block, which can also be de-stroked for "E".
Starting with a 6.0, you can get a pretty big "B" motor without the investment of an LSX block. We make over 1,000hp out of
a junkyard block/crank combo that cost us $700 WITH the .030" overbore. Can't beat it.

Hopefully this question won't sidetrack this thread but what heads are they using since most good heads need a 4 inch bore I believe.  Thanks,

I think everybody knows you can boost the pi$$ out of an LS engine & make power.
The question here was about tall deck BBC's.
Before the DRCE blocks, the TD BBC's were the weapon of choice. The 366 is still an over square engine & will not have a problem making power in natural or blown form.

No good heads for the bore size.

Dart Pro 1's or TEA heads for the smaller bores; we use "LSA" rectangle port heads (Caddy CTS-V) which like an overbore of .030"
Definitely wasn't trying to sidetrack the conversation, I just hate seeing someone spend lots of $ and wait on custom cranks, etc.
for an engine that may be less powerful and less reliable. Good luck.
