[quote=qwkmopardan]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. That's for sure guess Parson&Meyers, Tillburg and others have been over charging people for class motors LOL lol man you could have saved a ton of money

There were no 750 thermoquads. The factory generally used 800s on SBs and 850s on BB. There were some aftermarket ones up to 1000 CFM

I thought about that,but if I would go that route...then it's time for a 360...and I have several 318's here in my shop.
I know this is feasable..I've seen NHRA GT cars use a 318...so it can be done,but I dont think I need a super stock engine build to do what I would like to do. Keep in mind that a ss gt 318 is a short stroke big bore to make 318 ci.

Those SS/GT motors are pretty high maintenance too. A friend runs one...pistons w/ only one compression ring. Requires freshen ups every 50-60 passes. His "factory unported" cast iron heads cost over $7,000 a set. 7" torque converters, not to mention a trick Quadrajet. Comparing a typical low maintenance bracket motor to what these SS/GT motors run, well, it's just not a good comparison.

I have a 318 in my car. Times in my signature.
I think with more gear( run street friendly 4.10) a single plane intake ( knockoff dual plane currently), roller cam( currently a 231@50 hydraulic in it) more compression(10.5) good set of headers(99 dollar cheapies on it) And removing the power steering, factory water pump and fan, what I have with those mods would go at least 11.20's without much of a sweat. The heads are ported magnum RT units. Edelbrock magnums ported would I am sure make more power and save some weight. I can see getting in the 10's pretty easily with the right parts. I am shifting at 6200 and trapping at 5900, not optimal. This all said, this motor was built and screwed together with excellent machining and thought, that is definitely worth something.

Keep in mind that a ss gt 318 is a short stroke big bore to make 318 ci. No, stroke is only allowed to be +/- .015" from stock, and bore is allowed to be no more than .080" over stock.

Bw,s combo is running nice. While he did manage a 11.79, its other et,s were more closer to a 12 sec. combo IMO. Dumping the WP/fan/ps pump wont gain the .6 in ET imo, more like .25 maybe. Going from a 12 sec, combo to a 10.50 wont be nearly as easy. Don't let BW,s 231@ .050 fool you, its pushing .600 lift. Hes got a decent vert to back it up too. I will say, it wouldn't be a bad thing to Follow BW,s build and combo to do what you want to do though.

So a 318 is really a 340 329, the good rings stop at 3.970", the 340's end up around 352. As the years go by the max overbore allowed has increased to extend block life.

Most HP calculators will put 3000# and 345 HP around a 12.5 + ET

But going to a roller, more compression and gear, along with a head upgrade would make a big difference. Car has a flat hood too. That doesn't help. The cam in it now isn't the engine masters 247/247 solid. It's a hydraulic, and much smaller duration wise.

Can you make a 318 run 10.60? Yes is it cheap? No you have to have the right parts in the right place it can be done and has been done there are at least 5 or 6 super stock cars right now that can prove it but most of the replies about parts are way off wrong intake wrong size headers a 2 ring piston is 20 year old technology if you really want to know talk to somebody doing it super stock cars have nothing in common with bracket cars About time you chimed in I was feeling all alone trying to explain it.If it was easy and cheap everyone could/would do it.
