Stats - '85 K20 Burb 350(cali), 700r4 NP208, 10 bolt, 14 bolt SF, 3.73 I have the 350 ready to come out just have to go get the hoist from my neighbor. I have a fresh 454 on the way, it will be here Monday. I am having second thoughts on the 454 and just do a 383. Either way it will have much more torque than stock. Will not have emissions equipment. The trans shifts very good currently. But while I am here do I go ahead and change the tranny? If so, 700r4 or 4l80e? And if I do, who's? There are 100s of people building these trannys. I don't really have the money to do the trans but thinking it may be smart while I am here. Any input?
