First post here..
I'd like to build a 318 for drag race use. Max 8000 rpm.Would like to know what you guys would use for all parts for the build. However there are 2 items the engine must use...

Edelbrock cylinder heads

ThermoQuad carburetor.

No it's not a NHRA/IHRA engine for class racing,but would like to build along those parameters.

Cam,intake header size,crank,rods pistons,oiling system etc... what would you use?

Engine will be in a A-body Duster.

Welcome to moparts, hope you got thick skin.

Lots of cam (solid roller), lots of compression and a max effort port job by a reputable shop. Those heads are a little limited in cross section and CFM but you could probably do it with enough money. 1000CFM thermoquad.

Intake, probably heavily worked super-victor.

If the goal is really 8000 you may look for an old transam destroked crank. Turn it to 2.0 rod journals and get some 6.5 inch chevy rods from a good source like carrillo. Pistons are gonna need a small dome and heads milled as short as possible to get compression without a flame front restricting dome.

Oiling is probably past the limit of a stock system and will need a few mods, get some full groove main bearings, bush the lifter holes, radius the sharp corners in the passages...

Do you got a certain ET goal? I built an engine for a guy who wanted to turn 8000 and it did (was out of breath but you could push it there) with some heavily worked w2s on a 340 (bigger bore to help breath better). He was much happier with a 6000 RPM stroker in the end.

Only if the block has an X or an R on it. Otherwise skip it.

The head you want to use won't support 8k even on 318 inches.

Valve train will kill you.

Oiling is an issue. You must correct the oil timing. Otherwise, it will be spitting the chitlits out on a regular basis.

Welcome... what do you figure for ET or hp goal..
I'm one of the few on here that will rev a SB..
a big bore will help.. I've never used the heads
you want to use.. all my stuff is W series heads..
W-2 ,W-5 and W-9.. even my W-2s I was turning 8200
rpm but they flowed 305+... whats the package you
are planning on

What is performance goal?? Very very few small blocks need or will be happy at 8000 just no need Stock Edelbrocks are held back by pushrod pinch that is why Indy relocated the shaft position using big block rockers thus giving correct offset--opening up the pinch and allowing bigger springs which are the real issue with that head and that kind of RPM
A high winding 318 may be fun but would still be outclassed by a normal 408 turning 6500
1/8th or 1/4?
Think of the 340 W2 combos they ran back in the day with tunnel rams and 8000 plus They ate bearings -- you should be able to have MUCH lighter parts than they had thus helping a ton--The oil pan they used was DEEP--like 12 qt deep and used the old Milodon cover and two pick ups--all band aids you really need dry sump to make it live--bushed lifter bores a must and for that expense right there you can do the stroker
Main thing that will keep you busy is head gaskets--That kind of RPM requires a cam that needs mucho compression--and big compression on a 10 head bolt small block keeps you busy--I always ran clear tube from the evacs so when I saw vapor in the tube I knew it was head gasket time before it failed--I had good luck with more rod bearing clearance in high RPM small blocks
Belt drive--high dollar lifters--etc
Valve springs are the real limiting factor--with that goal bigger is really better and I would think titanium valves an absolute must--
All this if you want to make seriuos power--if you just want to glance off 8000 then no big deal

I would never try that combo--way too many shortcomings and just a $$$$$$$$ pit

I dont know who your talking to with this.. qoute
if needed

I've been racing stock 340 blocks and a R-block
for a long time... all of them turned 8200 except
the stock viper rod engine.. that one let go at
8200 rpm after about a year racing every weekend..
its all about flow and the balance of the engine..
my 395ci is still running strong and it turned 8200
every pass... my other stuff has gone higher

You willed need to do some major port work on the heads ( 300 cfm range ). With some mods, the carb will work ( even the 800 ). I'd go with a Victor 340 manifold, 1 7/8" - 2" on the primary size for the headers, Quality rotating assembly ( Forged crank, H beams, Diamond pistons ). Oiling mods as suggested for sure. Solid roller ( custom grind )from Comp, etc. I like ThermoQuads too. Have fun.

Goal is 10.50-10.70's in 1/4 mile. Have to be able to use 750 TQ. 8K was a guess on RPM,I was thinking 7500 actually.

Not interested in other combos..car will weigh in at 3300#.

I know it can be done,there are a few 318's running in NHRA GT classes.I know a roller cam is a must plus the usual mods..but the oiling system is what I am concerned with.

Drill out all the oil passages to the mains to
9/32.. I think thats the drill and blend the pump
so it flows better, use a high flow pump and .003/.003 on the clearances..dont use a heavy oil.. I like to set my oil
pressure at 18 psi on the end of a run at idle hot... a
goodvalve train is a must.. I use TD.. also I like to
turn down the crank counter weight and move the weight in
closer to the centerline... H-beam rods and light pistons
EDIT
I forgot... I bush the lifter bores

This is the info I'm looking for..thanks! Been out of it a long time,now have time and enough of being crazy to use the 318. I just see it as a challenge and it's really just a small bore 340 in my opinion.I've been looking thru my old Direct Connection combo stuff in the old "bibles" and I have a few real nice 318's but nothing else.

All info is greatly appreciated.

Light rod ( Manley cascar rod)
Light piston
Bush lifter bores
.030 restrictor to cam bearings
Good oil pan (Charlies)
Good valve train (Jesel, T&D)
Good machine work (Duh)
Going to work the head GT class cars have big money in the heads
No need to do any other oil mods waste of time don't out trick yourself
My racing partners class 318 runs 10.70/10.60 at 3200lbs.
My class 340 goes 10.50 at 3400lbs.

Thanks! What oil pump?

Transmission will be 904 with 8" converter and 5.12 geared Dana 60.

Reason for the Edelbrock heads? I bought them VERY cheap a long time ago,so I'm going to use them.

Valvetrain suggestions,camshaft,tell me what YOU would use or are using.

now tell him how much thats going to cost
better have deep pocket

Standard oil pump light oil
Unless you pump money into the head it wont run 10.70
What size tire? 14x32 will take 6.17 or 5.86 gear
Jesel or T&D no other way around it
Cam shaft is secret sorry to much RD to give that up just don't over cam it.
You might as well make it a class car....

Sorry forgot about that, a truck load...
But it's a blast for sure.

I saw that Duster at the Gatornats..in fact,I talked with you about the radial tires...

I was thinking 11.5x29.50 Phoenix for tires.

I wasn't asking for exact specifics on cam,but a general idea.

I used to race 440's back in the day,and got out of it,but I really like the small blocks.

Yep I remember, call Mike Crutchfield he can help with the tires 334-612-2058

Not to be the wet blanket, but you're bringing a sharp stick to a gun fight.
