400 chevy engine combo

[Anonymous-0]

I have a 400 chevy engine and was wondering if you like this combo, any suggestion appreciated..
400 engine- edelbrock super victor intake, 750 holley 4brl carb, 2.02 heads, cam-292/292 advertised duration,duration at 050 lift 244, .501/.501 lift, flat top pistons. Everything will be fully ported for maximum flow, what cc heads should i use to get a 10:1 or 10:5 comp ratio? I want it to run on the street on pump gas.

if you are really interested in building an engine as described I will give a bit of advice.first compression is power no two ways about it but running a 10.5to 1 400 with aluminum heads at 5,000 ft. above sea level is one thing 10.5 to one at 500 ft and iron heads is another.you can run about 1/2 of one point to one point more compression with modern aluminum heads than you can with any chevy head except maybe the vortech head.

the next piece of advice I have is unless you have a flow bench dont waste very much time porting beyond some port matching and a bit of bowl work the rest will probably only lose power. and again almost all the aftermarket heads will outflow any of the chevy heads.

next is proper bluprinting and machine work paying close attention to deck height as well as quench area also the longest rod you can put in there will help 6" is what I would do.

as far as cam advice call a cam rep (of your choice comp and crane are two good ones to start with) when you get the rest figured out.
if you pay attention to small details you could really build an immpressive torque monster but mix and match too much and you will end up with a gas guzzler the will get outrun by a 283.Paul

I played with Chevys for years. The 400 SB and 402 BB were the biggest pigs I ever had. I put together a 427 tall block and a 454 (early 74' engine) that would stomp any of the SB engines I ever owned without without too much more fuel. Then one day I got talked into trying a Cadillac 500 (also an early 70's engine) out of the box it had way more low end wallop that any Chevy I ever had and I never had one unravel even at 6 grand redlines. These days I've grown up a little and settle for 4.9L MPFI Cadillacs, 5.0 MPFI Fords and lone 5.7 TBI Chevy.

Different name but the same dreamer, again.
It appears you have this cam and other various parts,pieces and dreams of 600HP.
Take that factory Chev heads and tie to a rope. Now go fishing and use the heads as an anchor.
An aftermarket aluminum head will weight less, flow more, be more resistant to detonation and cost about the same as re-working an old set of used heads.
We still haven't heard what kind of a vehicle, transmission or diff ratio.
You maynot believe this but you can purchase a GM Goodwrench crate race engine. That will run longer, make more power and cost less then your home brew mix of miss matched parts.

Big-block-style power from a small-block engine!
If you're looking for a small-block Chevy that makes big-block power, we've got the engine for you! For the ultimate GM Performance Parts small-block crate engine, choose the ZZ383 – a combination of Fast Burn aluminum performance heads and a 383" stroker small-block that can add up to 425 horsepower and 449 lb.-ft. of torque.
A carefully engineered balance of torque-producing bottom-end power and horsepower-inducing Fast Burn cylinder heads combine for the ZZ383/425's stellar performance statistics. The Fast Burn heads have large 2.00"/1.55" valves and specially designed chambers that draw in lots of air and fuel, burning the mixture quickly and completely. It's a combination that generates great mid- and high-rpm power, which, when combined with the 383 cubic inch displacement, creates an awesome all-around performer.
The ZZ383 has a specially modified engine block and 3.80"-stroke crankshaft, which produce 383 cubic inches of pure performance. The reciprocating assembly is comprised of heavy-duty components including a 4340, nitrided, and induction-hardened forged crankshaft, and unique, heavy-duty powdered metal rods. It's 425 horses of bulletproof performance.
With the ZZ383/425, you get the power of a big-block with the size and weight of an aluminum-headed small-block.
If you've never driven a car with a stroked small-block and the top end components to support it, now is your chance!

HERE'S WHAT TO DO...take that 400, toss that cam you have into it, run whatever old junk heads are on it already, use that aluminum intake and 750 holley....and shoot the juice to it. Save your apparently limited engine building knowledge and a pile of bucks by just running a 150 hp nitrous kit on it, and have a pile of fun right up until you blow that rascal up. There's no cheaper HP than NOS, but it will definitely be a quick education. You'll get good at pulling the heads to replace head gaskets and draining milkshakes from the pan, and before long you'll know that old small block inside and out. But you'll be going fast, and cheaply- for a while!
THEN, buy the Smokey Yunick book "How to Hotrod Small Block Chevy ENgines" and read it so you know something about what you want to build.If you're bound and determined to run cast iron heads, this book will tell you all you want to know, and even show you how to port 'em.
BUT CNC and Aluminum changed the world, so I'd save the junk yard stuff for everything other than heads, because aftermarket aluminum is the way to go there. Do this only if you want to build something yourself- otherwise, buy a crate motor and DRIVE it,-spending time to sort the converter, gear and rear issues that have all been covered here ad nauseum, because until the bite is right it's just a nice motor on an engine stand ( we call 'em "coffe table motors").

what would you do in overhauling 427 BBC tall deck to make it a better truck engine?

 

[skip33652]

you did not ask me but I would find a piston that is as tall as possible and deck block to get .000-.010" deck height then use an early head to get compression up to 8.5 to 1( a 366 head will also work)you can add more compression than that for real light work but in a heavy truck I would not push 9 too 1 too hard.once compression is up a bit you could put a torque cam of some kind in .I liked the old melling torque cam.mine( built as described) takes 550 bushel of wheat to town( 30 miles) very easily and gets better milage than the 366 that the new 427 replaced Paul

Do you know of anyone that needs a set of new never used 8 exhaust valves and 7 intake valves for a Chevy 283 engine. The valve stems are .020" oversize? Hal

I know the owner of a 5 litre Mustang that competes in the fastest street legal drag races class. It means it could be made street legal with a few modifications. He's got a turbo small block putting out around 1400 HP! I remember him saying he did an 8.69 sec. quarter mile at I think 168 MPH. He has owned a large accessory and performance parts shop since the 60's. Dave
