Yes just watch how terrible a low cr 318 with factory stall and highway gears goes. With mild cam, mild porting, 4bbl and duals. Look at all the time spent under 3,000 rpm, felt like forever.

Doesn't stop you from using the same example of a car going faster with a smaller carb over and over and over etc.. again trying to make your point. No one is saying these videos are absolute proof of anything. But you don't like them cause they question you philosophy of strangling the hell out...

Yes, do you think he's that interested in this test? To spend a bunch of money, time and effort more than he already did. I doubt it but who knows maybe this is just the beginning and he's gonna do a 100's carbs on 100's of engines and thousands of dyno hours to get to the bottom of this...

You didn't prove ****, believe what you want. If you don't see how this applies obviously you don't get it, maybe focus on helping the OP.

So you don't know, but are guessing that I'm wrong lol

Proof ? If this was true a longer stroke engine of similar displacements would always produce a very noticeably higher lbs-ft per cid of similar level of an build of engine. If it did it would break the law of "energy cannot be created or destroyed" why some's belief in torque as some kind a...

Yes cause he should of spent a bunch of money on a little curiosity test.

You would be silly to not at least try to get around 9:1 while you got it apart.

Here's a bunch of 318 related articles.

Search here and youtube for 318willrun he's done a bunch of basic 318 hop ups, backed up with track results. Here's his youtube channel 318willrun

Plan on adding some compression ? Heads ?

I see nothing wrong with how you experiment, you seem more methodical than fly by the seat of your pants kind of guy, wrong/right that what your trying figure out.

Sorry, I meant 600 hp lol

Not mass, larger piston more surface area for force to be applied. When people see a 400 B engine vs a 408 they see 4" greater torque multiplication over the 3.38", but fail to recognize the greater force the 4.34" piston will have over the 4" piston to be multiply by the crank in the 1st place...

This build is still up in the air far as I know nothing is a 100% decided and I've never said that this combo of parts is the way he should go, I've repeatedly have said he should pick a cam and cr that works with his parts, I've said probably around 224-236 on 108-110. The point of the dyno...

Not to me, long stroke and torque which some how turned to low cr and 292 cams torque ability.

We weren’t even talking about stalls speeds.

I like how the venturi's are closer to each corner of the intake ports.. Makes me think instead of a single plane would something like a cross between a single plane and kind of a mini tunnel ram with a large two barrel directly above the front and rear intake ports so basically a two piece...

Nice gains at .300-.400" plus the general gains throughout, how much hp you have gained ? If you didn't hit the 500 hp your probably pretty close. But more importantly probably gained at least across most of the power band.

I was watching someone porting Ford FE heads and since on those the pinch is part of the intake, the head is really just the short side area and bowl, kind of made me think the first inch or so of the port is more part of the intake runner than the head itself obviously it's all one from chamber...

Even this stock ish 383 made stock hp but only 395 lbs-ft wasn't until they added headers and more carb did it hit 425 lbs-ft. https://www.motortrend.com/articles/mopp-0209-upgrading-the-383-magnum-avs-carb/ Torque RPM STK HDRS CARB INTKE CAM 3000 382.7 406.3 427.1 405.5 394.2...

Even with heads flow on the dyno it show engines at least under 7000 rpm aren't as sensitive as people generally make them out to be, maybe on the street and or track might be a different story, but with over a hundred years of automotive racing if small was generally better 200-599 cfms we...

By pistons mainly mean they give compression needed, and if you plan it right say you think down road you might get some eg.. tf 240 heads, you could make sure you piston will give the right cr with them too. Besides that, can the piston handle the power of any possible future upgrades same...

If the funds are to limited I'd make sure the bottom is done right (mainly pistons) you can always upgrade top end later in the car.

So it sounds like your build is gonna be a stock ish mild hop up. So basically rebuild what you got, don't worry about the 0.70" over, sounds like you got headers, do you have intake and carb ? If not probably find and air gap or similar, sounds like you got a 3000 stall and 3.73-4.10 gears so...

Ok, What do you think of this build, the dyno results are posted above. https://www.motortrend.com/articles/mopp-0209-upgrading-the-383-magnum-avs-carb/

That was for fishmens67, Shorty Thompson, Head wise what do you think you could budget for ? (I'm Canadian so I your guys money goes a lot further than ours so dollar amounts don't mean much for me) any aftermarket heads available in your budget?
