My old combo ran
10.99 @ 124 w/ 1.67 60ft. off idle (t brake wasn't engaging fully)
consisted of V1 S trim 7in crank 3.33 snout pulley
d.s.s girdled 308 10:1 cr
c4 w/ 4600 stall 28in tires and 3.55 gears... the car had windsor jr iron heads
holley systemax intake
e303 cam 1.72 rockers
75 t body 80 mm maf 42lbs JMS flip chip no fmu
@ 3200lbs making 498ft-lb at the wheels (through the slushbox)

it blew a gasket because i was unaware of the compression ratio.and was running pump gas ... not only that but the chip was set on the race gas tune,.. and the dude had stock pushrods that were getting chewed up by the guide plates...

i rescently switched the heads to aluim canfeilds same cc
crane link hydrolic lifters and new hardened P-rods
dropped about 100lbs and swapped the c4 for a proshifted 5 speed...
also gunna run torco 100 at the track this time...

should i expect 10.50's or better???

Thanks
