Thanks for the info guys. Right now my 493 is a stump puller, single plane, and a 260/266 cam, I'll have to dig up the dyno sheets to see peak torque RPM. Just on the fence if the trade-off is worth it, port velocity of the small ports to the flow of the large ports. Street/Strip type deal.


Faster, Faster until the thrill of speed overcomes the fear of death...

71 Swinger - slowly collecting dust/parts
66 Belv. II - just a streetcar
88 Mustang - turbo LS beater
