Ok, first of I want to thank all of you for your information and help with my never ending questions.

Let me start with what I have now, what I purchased, and what I want to accomplish.
My set up is as follows, 71 350 4 bolt main, .030 overbore, keith black ceramic pistons, HO heads off of a 305 formula, mild port,
11:01 comp. 225 psi per cylinder. Sig erson cam, measured at .060, power comes on around 2800,
Pulls past 7 k. EDL Victor Jr Manifold, single plane open plenume
high rise. Holly street avenger, 670 Tes Headers 3 inch single, high flow cat, dual exit flow master. 3.23 limited slip, stock. 5 speed . edelbrock pan hard rod, eichback
prokit springs, bilstein shock/struts, global west bushing, adco swaybars.
this may sound good, but it sucks. my power is not streetable,
gutless below 3k, rocks back and forth like a full race cam, but doesnt run like one.

So here is what I purchased. I purchased a XE 274H, lifters, pushrods, Offenhouser dual plane highrise, 360* T5 borg warner 5speed from a 95 camaro
Now here is where I am lost, I run a Falkien 451V in a 235/60/15v
front and rear, I want to change my rear end to a deep gear, like a 3.73 or 4.10 but I want to still be able to drive it on the freeway
in 5th doing 80 at aor around 3 k.
also, dont realy have the money to purchase a posi, so I was thinking or changing my ring and pinion,.
will this work?
Have already started changing the cam.
thanks for the help.
oh yeah, what color speedo gear would I need to run with your
advice.
Tarrent.
