i dynoed my 500" motor today.re cap of the motor:
500" 4.380-4.150
13.1-1 cr
indy cnc sr,s flowed 367@.700"
comp solid roller 272/276@.050 .703"
t&d 1.7 rockers
differnt intakes
it did what i thought it should do.it liked 40* of timing.
with the indy 440-3 with a 1050 dominator: 710 hp @6700 652 tq @5500
mopar 337 with a 1000 cfm 4150: 692 hp @6500 640 tq @5200
indy 440-2d dualplane with 1000cfm 4150: 677 hp @6700 604tq @ 5300
the averages were:
337: 536 hp 569 tq
440-3: 541 hp 573 tq
440-2d: 533hp 572 tq
ran out of time today,so sunday i will be dynoing a 440-2 w/ 2" spacer to a 4500.i'll post the results when i have them. i will post the dyno sheets on monday.they look good with a nice broad torque curve. my thoughts:the mopar 337 manifold is a awesome piece.very close to the peak numbers,and will fit under a stock hood.makes it nice also to be able to use a 4150 carb,nice street manners.i guess the motor likes the short runners.i also had a 1/2" spacer under all the carbs.
all in all,it went well today.this motor should make an awesome street ride. next up,chassis dyno.going to see driveline loss.also see if there is any more left in it.my 580,i found 27 more horsepower on the chassis dyno,we'll see.
