here's what I have, very similar to what your doing, and i'll tell you my experiences.
i like to play at the roll bar rule, keep this in mind.
74 Challenger - 3660 lbs. with me in it
30 over 440
11:1 weisco pistons
stock rods with good bolts
stock stroke crank
main studs
1/2" hemi pickup tube, block drilled and tapped for 1/2"
milodon lo-pro oil pan w/ windage tray
stage 2 ported indy ez heads
crane 1.5 gold rockers w/ good shaft hold down kit
hughes cam - hydraulic - .548 I - .555 E - 238-242 @ .050
edelbrock timing chain
mopar m1 intake
worked quick fuel carb, 1100 cfm
hooker super-comp headers
3" exhaust out the back w/ thrush "flowmaster-style" mufflers
70 18 spline 4 speed
ram clutch and flywheel
lakewood bellhousing
3.73 8 3/4 rear with the good sure grip
strange axles
6-an fuel system with holly blue electric pump
275-60-15 drag radials
full interior - stock seats
i have a best time of 11.63 @ 118.8 . average 11.7 to 11.8
i can run pump gas, but i do notice a performance difference. i usually blend 93 Sunoco with 114 and it's a little easier on the pocket. this is such a fun car to drive. ripping through the gears is awesome but the 4 speed is definitely the thing that's holding this car back. with an auto and the right converter, i could probably go 4-6 tenths faster. like everyone said, you will do better racing an auto over a 4 speed. the biggest problem is getting a good launch. it's just practice, practice, practice. don't expect to win a lot
at first. i wanted the 4 speed over the auto though. for me, it's all about ripping through the gears. whether it's on the street or the track, i love doing it every time. and that's why i'll go a little slower over the auto. for others, it's all about the consistency and winning. i'm just out to have fun.
oh, about the roll bar rule thing. once you go faster than 11.50, there's a whole different set of rules you have to go by. i don't want to have to put the roll bar in my car and i like having the stock interior. the safety rules i agree with. i have good axles, bellhousing and a drivshaft loop. even with running in the 12's you gotta think safety too.
