Typical bracket guy isn't going to build a 318, bracket guy wants to go as big as he can as cheaply as he can.

A bracket 318 could have a head with 50+ cfm, and 3 points more compression than a Super Stock 318. $7K-ish would get it done.

Oh so true...

need to adjust your prices a little
heads and intake port work 7500.00
jesel or t&d 1600.00
valve springs 600.00
rings 600.00
piston 1200.00
cam & lifters 1200.00
if you get it right the first time
custom convertor 1200.00
carb mods 500.00
machine work about the same

I for one cannot see it taking 20 grand to make 545 hp out of a 318, a stocker, yes because they have to work with "stock" parts, no comp, stock 400? lift, stock intake. But ported heads, big roller cam, high comp pistons, with today's technology I think it would be easy but a very peaky engine with much rpm. 340 stocker engines are turning 7500 with stock J heads and intake with a TQ. Just read about a 273 running mid tens(and not a D Dart). Go for it, compression will be your friend.

Ya i may be thinking of mod/ss they only P&G they don't check bore & stroke. unless its over ci

A .060 over 318 would need 1.66 hp per cube to reach 545 horse, since we are NOT required to follow the paramaters of a superstock engine. How could a 328 cube engine with ported Ed heads, a .720 lift solid roller, Jesel or T&D paired shafts, and 13.5:1 compression not reach 545 horse at a reasonable cost?

I dont understand the doubting. As far as the rpm ceiling, way way back, my pops bracket raced a 340 powered car every week, shifted at 7200 and traped at 7300, had TRW 10 pound dome slugs, STOCK rods, Crane ductile iron rockers, and a flat tappet cam. So a 318 with strong lightweight honda journal rods, lightweight pistons and pins, thin ring pack, titanium retainers, roller cam and paired shaft rockers with excellent geometry there is no reason it couldnt withstand 7600-7800 reliably

it realy is irrelivent weather it is a stocker a super stocker or a bracket engine the same basics hold true,how efficient of an air pump can you build? it takes ring seal,cylinder pressure, and reduction of parasitic drag those factors will tell the story
when you figure out how to master those items you will learn to go fast grasshopper

But master I thought it could be done for less then 7,000. Buy off the shelf parts have your local Napa do the machine work bring it home put it together and poof its magic dang it...

Give Bob Mazzolini a call. He raced a 318 for a long time. Cast crank, low compression, QJet, etc. I think he ran 10's in a Sebring. He was selling off that stuff last time I talked to him, not sure if he still has a pile of parts or not. I think he was using a factory cast iron head so you're ahead of the game there.

From what I recall, Bob's car weighed 3200 lbs and ran 10.30's so he was making roughly 570 hp. That was a class car, GT/IA or something like that. He was 9:1 compression and iron heads so if you switch to aluminum heads and take the compression to 13:1 or so you should be able to get by with much less expensive headwork. Cam might be a little different due to the higher compression ratio but most everything else would be the same.

Agree, apples and oranges in parts-price

a little off on the weight and horsepower less weight and less horsepower

I'm not building a GT engine. Sure I'd like to,but the wallet and life in general says no.

I'm using what I have,and buying what I dont.

I'm going to build it. If I go 10.90's I'll dance the 2 step boogie.

I'll be very honest..part of the reason too is my first car was a 318 Duster. I did the usual bolt on's and it ran 14.20's. What I liked was that those I beat,were surprised and embarassed they got beat by a 318.

Grasshopper may be younger than you, but is no spring chicken.....Kwai Chang Kane been involved in Super Stock many moons, and build engine from time to time. Latest offering has taken the pebble from your hand many times on qualifying sheet.

I think most on here are just not only trying to keep your costs down but trying to help you get more bang for your buck. If you keep an open mind and grab parts for the right price 10.50's can be had on a budget. The last block (340), Scat rods, Diamond pistons, Scat cast crank (4" stroker), cam and lifters, timing chain and gears, new rings, and Milidon oil pan and pick-up cost me 1350 dollars. Its all machined and balanced ready to assemble. Deals are out there and I promise you this one will be faster than 10.50's. Lets see how much that 318 costs to run the same. Same with heads. I've found sets of Edelbrock heads (some on this site) for 500-800 dollars per pair. Be ready for when the deal comes strolling by.

Ok so you're talking Super Stock, his weight at 3200 puts a 340 car in E or F class. The current records for SS/D-9.07. E-9.24. F-9.33 G-9.46, that's porting the heads, any cam, stock compression any 4 barrel intake and stock factory carb. I'm sure that takes big bucks to massage those parts to the hilt. So if he puts the same money in his 318 (22 ci less) why couldn't he run high nines? For a lot less money 10.70 will be easy. $7500 to port a set of heads and intake, that's 150 hours, likes 10 hours being a month, 8 hours a day for 19 days, somebody's getting ripped.

I get that and trust me..I REALLY appreciate all the insight. Hey we have 6 pages of info! More than I ever thought would happen,and that's off of my first post here. Now you guys know why I came here FIRST.

Still going to build the 318 and see what it will do. No GT racing though...too expensive.

318 racer... I posted a thread a good while back about building a Magnum smallblock, and it ended up with a pile ov neat info. I cant remember exactly which thread ov mine it was, but search my threads and it'll be there. In it i remember someone talking about a pretty obscene 273 build. I think it started with that article (Mopar Muscle???) about the 455HP stock Magnum 360 short block/Edelbrock top end build. I think if people would just forget that the term 'super stock' ever entered the conversation, ideas about costs would remain a lot more reasonable. I've seen some truly junk [censored] all-out FLY around here... and i am stuck dead-center in Chevy and Mustangland.

I was jumping in on the Kung Fu TV show themed banter, was supposed to be funny, guess I shouldn't quit my day job lol.

A 71 340 in an A body will only fit in I, J, or K in Super Stock.

So 318 it is lets start with the blocks. what years. you will want to tar them all down and have them checked.
I would rather see you at 20 or 30 over and have a stable hole.

Sounds like a fun build, but I would vote for a 4" crank as well. A cast mp or scat crank would work well and they only cost about $350 and add 50 cubes. It would make more power and be much more reliable.
Another thing to add is that for bracket racing the high winding sb can be a nightmare to keep consistent et round for round. They are more sensitive to atmosphere conditions and shift points.
A stroker will also be much less sensitive to gearing and stall. As for these thoughts the op can take it or leave it.
A high winding 318 would be fun, but much less reliable and more expensive in the long run.
