There are plenty of guys up near there. There has to be somebody with HPT up there check around. Ask in the GM General section if anybody has HPT up in your neck of the woods. Nelson could probably do it but he would have to send you a computer then you tell him what is wrong then him send oyu another one. With probably 4-5 tunes he could ahve it perfect. He has tuned ALOT of 4.8s with the TR224 which is only alittle bit smaller than the TR 227.

he told me that he could get it pretty much right on with the first tune. i do have a 5.3 though. im sure like 1slow01z71 said he will get it right with a couple tunes. allen is the best though. just let me know either way is fine with me.

there is no need to go with a cam that big in a 4.8 unless you do some headwork and gears along with the stall. Its like trying to force a large amount of water through a small hose your only gonna get so much threw the hose doesnt matter what sort of pump (cam) is on the other side. You really want to get alot more water (hp) through the hose (heads) you need to upgrade.

I think that cam and some stage 2 heads would do well along with 4:11 and a 3k stall.

Oh and if you really want to make its full potential get hp tuners.
