It did start drinking water after the second pass yesterday. Engine is old and I sonic tested the cyl walls a couple winters ago and they were on the thin side, but a lot of cash was already spent so he had to use it. Just used his car as an example of capabilities of eddy RPM heads. Only flowed around 275 IIRC. Those heads on a 318 would feed it very well and only a high 10 second goal, easy. $6000 budget would get him an engine to do what he is looking for.
was there any fill in the block Dan? we pushed our old 340 block close to those numbers before a rod let go (150 passes), but it was concrete above the core plugs and aftermarket 2 bolt steel caps. Do you think sleaves would help or hinder a project of this magnitude?

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. These naysayers are ridiculous. You need about 540 horse to reach your goal, you already have Ed heads, get them ported by someone good, they will go over 300 cfm at .700 lift when done properly, this will support over 600 horse. Being small displacement it will need some rpm so build it with that in mind. Honda rod journals with rods atleast 6.300 long, good light pistons, 13+ compression, paired shaft 1.7 ratio rockers, spend time to get the geometry perfect, ported super victor intake, custom solid roller with good PR oiling lifters. Have the carb done by a superstock carb builder, and youll be there.

You might want to look at Hughes Engines re; those heads. They sell a fully ported version that "they" claim flow 299cfm @ I believe .700. You also might look at the larger ( big block version ) of the TQ. I believe it is rated at 1100 cfm. They are identical on the outside. Just larger primary's.

The claimed flow is even higher then that. 305 @ .700 or the big mouth version at 319.9 @ .700. Flow ratings of their 3 port sizes are here: http://www.hughesengines.com/TechArticles/1headflowchartscomparisons.php#SBLARPM

"my friends 64 Dart"..... thinking that's the one that just split a bore in a block I was reading about It did start drinking water after the second pass yesterday. Engine is old and I sonic tested the cyl walls a couple winters ago and they were on the thin side, but a lot of cash was already spent so he had to use it. Just used his car as an example of capabilities of eddy RPM heads. Only flowed around 275 IIRC. Those heads on a 318 would feed it very well and only a high 10 second goal, easy. $6000 budget would get him an engine to do what he is looking for. so you are saying you can make a stock stoke 318 run 10.70s in his 3200lb car for $6K?

LOL. I only have 7500 dollars in my whole 422 build including my R3 block and Indy heads. I love reading about guys wanting to do things the HARD and expensive way just to end up paying more to go slower.
1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.38@138.67

I can assemble the engine,no problem. The machine work,not sure on the cost,that I'll have to discuss with the shop. They are very good at what they do.
Some parts I have,most I do not. The Edelbrock heads that I got on a fire sale are the 60767 heads which are bare heads,but they are the NHRA legal replacement heads for the 318.I never looked at them until today.
Even if the car ran 10.90's I'd be very happy. So you need porting, valves, springs retainers, locks and rockers... thats a fair amount of money in itself.. and thats not even going with Ti valves

I missed it by a little. If he assembles it himself about $6300 Grind crank $200 Pistons and rings $750 Scat rods $350 Main and rod bearings $125 Balance assembly $300 Bore and hone w tq-plate $275 Square deck block $175 Align hone block $300 Hot tank and crack check block $125 Cam bearings and freeze plugs, installed $125 Restrictor tubes and oiling mods. $200 Timing chain set $100 Cam and lifters $325 Porting, valve job and springs $1000 Victor 340 intake $300 Hughes rocker arm kit $500 Port intake $225 Smith Bros pushrods $175 Cometic head gaskets $175 M72 oil pump $45 Moroso oil pan and pick-up tube $300 Other gaskets $100 oil pan, intake, rear seal, timing cover, etc. ARP main cap bolts $50 ARP head bolts $85
Did I miss anything? good luck with that, the RPM'S will kill those hughes rockers in a minute. the cam and springs it will take to get there will probably be a lot more than you quoted. sorry i just don't see it. be interesting to see this happen. you could save the class racers a lot of money if you could make it happen.

OP, as someone who has also spent a lot of time and money on an oddball combo just to be different my hat is off to you. It's fun to go fast with a motor others look down their noses at, and to have people come look at it and tell you stories. BUT all that never put a dime in my pocket and eventually I got tired of trying to push a large rock uphill. Good luck with your quest for the 10:70's.

(no reference to Hemi, just a saying... hope he understands ) it's just the OP wants a 318. Most of us agree there's a lot of approaches to use different combos to run harder, for less coin, but the challenge is there. If he follows through, I hope to hear some results.

That's for sure guess Parson&Meyers, Tillburg and others have been over charging people for class motors LOL

LOL. I only have 7500 dollars in my whole 422 build including my R3 block and Indy heads. I love reading about guys wanting to do things the HARD and expensive way just to end up paying more to go slower. Doing things the hard and expensive way? You mean... like building a Mopar ANYTHING instead ov a Chevy? Hahahahahaha. So you'd rather run a Mopar. Why? you could go faster with a Chevy for less...??? I mean... if its ALL about money right...??? Way back at the street races, easily one ov the coolest cars there was a ratty Maverick with a 289. Not a 302, not a 351 (like everyone else was running), no stroker... just a lil tiny V8 with a stroke that barely shows up on microscope. That was a damn fast car. The only reason it wasn't faster was because buddy was piss-poor broke and had a weird way ov doing things. He'd rev that lil turd to the moon on weekends and daily drive it 40 miles to work and back the other 5 days a week. He said there was an easy 70HP left in that engine, and by the junk he used and the compromises (very first gen Edelbrock heads, CR in the 8's, and a REALLY crappy exhaust) he made, i do not doubt it. That car could have easily been 200lbs lighter too. Some people LOVE the revs... I'm personally watching this thread, as i've decided to (probably) build a 318 Magnum for my car. If there was a 340 Magnum i'd build that, but there isn't, and no reasonable way to build one, and i like more about the 318 than the 360. I too want a lot ov power, and have an embarrassing budget... but i'm a tricky guy. I know there's a way. I wanna explore the Edelbrock Magnum heads though... for a more efficient engine (Mustang mods and import N/A ratios have all but killed 'old school' for me), unless there is an even more modern design out there that doesn't cost much more. I'm 'only' looking for 450ish HP though... heh heh...
