Change the intake first  Any high rise single plane will work better and be quicker, IMO

Can you give us a time slip Or all the numbers to see where its lagging... how many revs do you take it to and what do you launch at(rpm) and shift at

jn responce to the intake. koffel's said they tested a bunch of intakes and the torquer made the most power, i don't know. also mr p body i am leaving at 3500 and shifting at 6000.
Can you give the cam specs at .050.... and what the
cam is installed at(centerline)... thats some REAL
low rpm's to be shifting at unless its a all torque
engine

Well if it makes peak power at 6500 why are you shifting
at 6000

Mr.P, Mopar advertises that cam's duration @.050 as 275. I think in real world measurements they are 282 @.050. It also has a lobe separation of 106,might be part of the problem with his stroker?

If it has a duration that high he needs to really step
up the revs.... but the intake and probably the carb
are holding it back... if he would post the time slip
it would help alot....with the 106 LSA he should have
all sorts of low end power and have some decent 60' times

By chance, you arent using MP valve springs are you?
The 60' is soft for a 2800# car.... but the whole
pass is soft

i don't know for sure about the valve springs i will check. why are they bad, soft ,not enough pressure or what? thanks.
Way under pressure for what you really need. I ran
them 1 time(full season) and from the moment I let go
of the trans brake I went to valve float for the whole
run... never broke them and thankfully they went into
coil bind before the valves hit the pistons.... I
figured they were just worn out but when I checked
the new springs to replace the old ones... they were
identical pressures.... junk

If it were me, I would be changing the cam, intake, rear gear, carb, and converter  My combo would have been a solid roller 280ish @ .050 .700ish lift, single plane with a 1050 dom, 5.13 gear and around 5500 stall and let her eat  . With that being said, the things that in my mind absolutely need to be changed are the cam and intake. There are lots of great solid shelf cams that are way better then the .620. The intake is really hurting your combo as well and I believe it should be changed. You're geared perfectly for and have the right converter for a big block stroker, unfortunately you have a smallblock!! As Mr. P stated, you need to rpm the motor to reach it's true potential. Shifting it at 6000 isn't doing that.

At 2800 lbs you should be well into the nines.
4.56 and 31" tire will work good. I think the cam is in need of improvement,
5300-5400 for converter would work better too.
Opps, misread it. Thought it said 33's. I still would have went 4.88 even with 31's. The 4.56 will suffice, but the converter is light, the intake is all wrong and the cam is so 20 years ago
