This is what it ran , how much is left in it

241@ 50 isnt “ big” for a 4 inch arm, at all. Even at 10 to 1
My cam is 260@50 in a stock stroke 360, that might not even be 10 to 1 .seems to work OK. Convertor is everything. Been right at 119 before, at 3300, very mild eddie heads.
Based on the mph numbers i am seeing with that blueprint stroker, actually in cars, my guess is the heads are very limiting. A real 445 horse, or even close, should run in the 11’s at 110-112 falling off a log

Folks are running that fast or faster with 340x heads & less. If the calculation of multiply you head cfm ×2 is anything then he's flowing 222.5 cfm, I think edelbrock heads flow more than that. 440 source recommends that cam for 440-470 cubic inch engines for street cars. How much converter do you run ? What are your heads flowing? & who's [email protected] cam ? There's a difference though in working okay & working at its best. Unless your 3.58 stroke 260 @.050 cam is custom ground so your intake closing point isn't up 68-70 degrees your giving up massive power down low. Hughes engines told me my best compression level with the howards 260-264 @.050 cam to make the most power that cam has is 12.5:1, mines 11.4:1 and 471 cubes. but I want it a little soft off the line, & it's to be a street car pump-mix.
