All of these numbers and what it should do math is something I’m not use to doing. I’m not sure most people get it ether. While I’m not so concerned at the moment, I’ve had people tell me my car should ET or MPH the same with 2.94 or 3.55 gear. So I say (just fishing for fun) it should pick up 4.10’s. The over all answer was no.

Yea, the car meet crowd…. Such smarty pants they are.
I’ll stick with the been there done that guys.

In agreement here...also some aren't that good at math, in general not saying about anyone here...I don't prefer 1/8 mile drag racing and I don't pay attention to those who convert their 1/8 time to 1/4...I don't believe its accurate, too many variables. Run the car 1/4 then show the slip, or state your 1/8 time and leave it at that.. I do realize I am an anal orifice and have been told many times :lol:

Asking for my own knowledge, do those rockers direct swap to LA heads? They look to be positive stop, like a Ford Windsor or are they adjustable?

The Magnum and LA rockers do not interchange.

When I posted the “Hint…” I was addressing 318WR about the intake if he was going to run LA heads.

buddy of mine had a 67 cutlass 330- 320 hp said ultra high comp on the air cleaner was 10.75 to 1 as i recall 2 speed p/glide and 2.56s gears came with the 800 cfm quadrajet all stock but dual exhaust 1.76 1st gear ratio it went a 100 mph in 1st @6000 rpm the car was a hoot 360 lb feet of torque
 
What size engine?
My wife and I had a ‘67 Olds 98 w/a 425 unites high compression engine. IIRC, it was an 11-1 engine. It was a beast and very comfy.

330 cubes 320 hp might have been 11.2 to 1 i liked the ultra hi compression on the air cleaner
the 800 carb was very loud when punched at 40 mph in 1st lol
edit
online it says 10.25 to 1
it was higher then that said premium gas or super only as well

Ok I get it.. my eyes went right to the rockers, they look like Ford Windsor. I never had a magnum, only LA small blocks. Honestly I get thrown off when guys call the 5.2 a 318 because I think LA engine. I have since learned though that the magnum heads are better than LA 318. Or i think they are anyway, ya cant beat a roller cam also.

the 1/8 mile conversions are spot on
if you convert the 1/8 and come up short its a tool
maybe you ran out of gear
they are all tools
no math to do its a calculator just imput the numbers
a 10 yr 0ld can do it
 
1966 olds 425 "super rocket" was 10.25:1 and did say "Ultra High Compression" on the air cleaner as well as the compression ratio.

That somewhat heavy and long 98 with an "anti-spin" rear would actually pull the wheels if the gas pedal was mashed and released 3-4 times.

Ill try and put it another way . Why do people talk themselves and their car up on mathematically calculated 1/4 mile times when they never ran the car down the 1/4 mile. Why not be "honest" and report their 1/8 mile timeslip? For example, say "oh my car does blah blah blah in the 1/8..."

They are better flow wise and a smaller chamber can be a plus or a plus plus if you run a piston to zero deck and gear a hood quench. There not a super huge gain but do show better. When it comes to porting, they do port out nice, but, I leave this to the head porters to tell the tail and splice hairs on what’s what.

You can beat a roller cam. It’s build dependent. As well on how the cam is ground. Just because I is a roller cam doesn’t mean it will out power or out mileage a Hyd or solid flat tappet.

IDK. Report the 1/8 and know the 1/4 numbers in theory.
Just the opposite for 1/4 mile guys? Seems like to much crap to keep in the head. There was no 1-8 mile where I grew up.
All of the tracks were 1/4.

I think its the same with me. 1/8 was for the junior dragsters...:) eh well maybe I'm old, anyway racing was fun back in the day...back when the stands were full of spectators, even at small local events. I'm looking forward to 318 WR putting up some real numbers with this build . I sense he's a guy with something to prove, you know "318s get no love " and whatnot.
Its all good.

3 joe blow, car meet crowd,magizines test are 1/4 mile

I set out to that but I had to sell the Duster I was screwing with. I had a little fun. Slow going but it was with the idea to March down in time slips a little at a time and show what different things can be done and why certain things were done.

I started with a low compression ‘79 - 318 in a ‘74 Duster a long was back. I may yet do that again on my YouTube channel for fun.

I don’t think 318WR has a sh#%in thing to prove but what he is doing is having fun while showing the world. He has a nice following on his UT-channel by having fun.

The not so loved 318 is labeled with the basic “Grocery Getter/People Mover” moniker and is a well earned title but the engine gets over looked and for good reason. Back in the day….
(Enter back in the day dreamin music when we were young and remember. Below is mostly for the younger crowd.)

340’s were easy to get and the 318 was littering the streets in daily drivers.

(Heck! The one I got in my ‘79 Magnum has detailed records by the original owner I purchased the car from where he stopped recording miles at 323,000 or so.
He did that in 10 years of ownership. I asked how and said he hated flying as you don’t see the USA that way. So twice a year he packed up the two kids and went somewhere new.
He stated he didn’t see Mexico or Alaska. But everything in between. The story drones on from there until I got it.)

Oh- wait-drifting here.. back to what I was saying…

Since the 340 was earning its reputation as a high winding giant killer in the A body cars, there was no reason to use less cubes. A few of us used what we had on hand. The 318. It is a challenge to make smaller to faster. That is one reason why I think he sticks with it plus he has it on hand.

It’s in the owners court what to do with what ever budget they have. So, if you don’t have a lot of money to say, start with a $700-$1,000 cost of JUST a 340 block, your not alone. Besides, a grand in parts to a long way and if your wise, I can really pick up your 318 very well.

While the 318 built with the same parts will never be a 340, sometimes you just gotta work with what ya got. Sometimes you do it because you want to.
