When you had it dyno’d did they say anything about performance at 6000 rpm + ?

Use to assuming that 5252 rpm is at crossover, which it would of been if they use the same scale for both.

If you look at most of the descriptions of each of these velocity FPS #'s most the list is fairly useable except vary top and bottom which is a huge difference in in port volume, and if your turning and decent size engine to even relativity moderate rpms your more than likely be higher up in the...

Most of us aren't building Darin Morgan type engines. Generally it comes down to the head that's is the best compromise and is readily available to us. But still functional and for most they would have a hard time getting close to that level of port volume mismatch. Not saying velocity ain't...

Most aren't running standard transmission. Your advice is tailored to your driving style, wants, needs. (which is fine but doesn't mean it's universal) You don't even think a well built 318 is satisfactory anyways, nevermind less than Ideal 318. Betting most hopping up a 318, are more in this...

Yes I know. Ideally but obviously it ain't as sensitive as some make it out. People bring velocity a lot especially warn about too little velocity never really hear warnings about too much though (which is a thing), but those that warn seem to have no idea what the right velocity or csa or...

I was being sarcastic towards AJ book :) 318willrun's car is exactly what AJ says not to do or it will be a slug compared to stock, which obviously it isn't.

Yes just watch how terrible a low cr 318 with factory stall and highway gears goes. With mild cam, 272/272, Lift .454/.454 110 IC 62*, mild porting, 4bbl and duals. Look at all the time spent under 3,000 rpm, felt like forever. (Sarcasm)

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...
