I have 4.10's in my SS with a 275/40/17 (25.66"). The ZF has a 0.5:1 OD ratio in 6th, and I turn 2400 RPM at 80 mph. It's perfect.

If I were to run a 29" tire, I would need a 4.63:1 ratio to keep the overall ratio the same.

thanks guys . i guess ill go with the 456 because ill be runnin 295 40 20 . little league is finally done, so hopefully i can spend some more time on this project and get it down on the wheels. bill

First gear is very usable, but you dont stay in it long. It's great to get the tires smokin good and then go to second to hunt ditches.:woot:

few pics
 

few pics,starting to work on tne front end. had to make a rad support because ive made so many changes .the rad & cond are low in the frame to keep room for the intake work. i used a hood from a 07 tahoe and skinned it,i had to glue it and use pillar foam to keep the tissue paper like skin from warping then tacked it in place till the glue sets up. thanks for checking in bill

Hi Bill, awesome job you are doing. If my truck looks 1/10 of what yours is going to be I'll be one happy camper. I have '68 C10 also that I'm putting an LS2 and a 6 speed automatic tranny in. I have the motor already and will buy the tranny in approx 6 months if my budget allows. If money gets funny I will go with a 4L80. Also, for wheels I plan on 3-piece 22x9 up front & 22x12 out rear. I'm just buying parts right now though. Keep up the good work. Your truck is sick!!!!!!!

THANKS FOR THE POSITIVE FEEDBACK IT HELPS MOTIVATE ME.. BILL

Oh Bill, by the way....I may have to steal that little tailgate spoiler idea from you. LOL!! By the way, on a serious note, I'll wait until your truck is finished though because my project is far behind yours. Can I send you my tailgate and you make me a spoiler like that??:hail:

Hood looks good. I really like it. I'm interested to see if you do some sort of engine cover. I want to do one for my 6.2L, but I'm not 100% sure what to do yet...:cheers:

Details!
 

Love how the hood and roof now mimic each other! It's all in the details! :thumbsup:

thanks guys, beleive it or not that rear spoiler was only a 3hr project (worth every min) my pics are of the hood/front. we cut the front snoot to bring the bottom out further than the top. i didnt know how i liked my hood pins pulls back or forward?? thanks for checking in bill
