Farmall 450 intake vs stock


Recommended Posts

Looking at upgrading my pulling engine some. I already have the "cold" 450 intake but found a Johnson lp intake. I read they are less desirable on the exhaust side but the intake is good. Thoughts on if the Johnson would make any difference over the style I already have?

Only thing to do is measure it on the dyno . 
Might put mass air flow meter into the test . Measure stock ,the change to Johnson’s lp 
I f you don’t measure , it a guess.

I'll have to if I ever get around to it. I don't have a dyno so finding one who isn't hundred an hour shop rate plus the other expenses of intake gaskets etc.

well I know cost is important , not everyone has these resources . Put on and try it at pull you , I d would try to keep everything the same carb , see if it makes a difference. You definitely hear the report from the exhaust will have a crack to it. 
I had this thought from mini engine days exhaustion only needs to be an 1/8 inch bigger  than the exhaust valve. And smaller exhaust means the exhaust gas has to move faster to escape ,if the exhaust pipe is time correct to the pulse of each stroke you’ll get much higher scavenger vacuum , more suction on intake , with cam timings should be worth a try anyway. Take a look at torque tubes the put on the 1/8 mile dragsters 

just a suggestion

450 exhaust and an ellis lp intake would be the best. For a motor that isn't on the huge side I would use a 450 manifold and bore the  throat out up to the runners 1/8" or so.
