I got 3 or 4 that need dyno’d…
I think the carburetor is holding you back on Horsepower.
Just my opinion ( so take it for what it is), could be the intake is too smooth also, as in your getting droplets instead of vapor in the fuel charge.
Got any regular 272s data from the dyno?
Send em in...
Could be the carb for sure. I bet it would like more. I'll have to see what can swap in sometime.
Never had a 272 on the dyno.
I think it’s a mistake.Awesome thread. @Red97, you do super cool stuff.
Do you think an OEM cylinder would make a difference?
I wonder how much affect the 359 case has on performance. Would more case volume be helpful?
Chainsaw Jim extended the transfer lowers on his down to the case feeds. That had to add a lot of case volume.
I’m working on a 359/272 hybrid and was considering going the other way: filling the 359 case feeds with epoxy. Not really because of volume, just because they create a dead space. But it does reduce case volume. Do you think that will be a mistake?
I am wondering about case volume mismatch. Have you considered adding some JB weld to the intake floor? Easily reversible and you have that awesome Dyno.
My bet is that the 272 cylinder can’t fill. Very tight cases need less intake duration.
