curious what kind of gas mileage you get out of your setup?

[1983zsled]

@Energi2DmaxX With the 700R4 and a 3.23 posi I cruise on the freeway at 70 mph at 2250 RPMS which will give me about 22-24 mpg. Overall it depends on how much I stuff my foot in it, but I'd say on average I'm getting 13 to 15 combined. I have a 3.42 Ring and Pinion I was thinking about putting in but from what I read it won't make that much difference. I use the car as a cruiser so 3.73's or lower are out. I rebuilt my Q-jet and it is tweaked for performance. I'm very happy with the carb!

Dude Nice Camaro....I putting a 350 vortec swap in mine....I bought a 1982 Z28 and bought a 350 vortec 4 bolt main and (4 speed transmission--original)Had to get a fly wheel for a 70's chevy pick up,a 70's corvette clutch,and waiting on a starter im try'n and corvette starter,but i might need to get and Off road use only starter....but anyways I was going to put the Exact Paint job on my car..lol

@TruAdictionv3 Sounds like a great plan> I'm very happy with my set up for overall drive ability and performance. I to have a built 700r4 4 speed, with corvette converter, servo and better internals ie 480le. With a 3:23 possi i\I'm only turning 2100 rpm's at 70 mph, but with the low 1st gear, you can get a great launch. I put on firestone firehawk 500 tires on, I'm extremely pleased with dry traction on launch. I still get wheel spin but not like traction t/a's. enjoy your project!!!!!

@TruAdictionv3 hey man if you dont mind can you give me sum suggestions on my 82. I have a video on my channel if you wana see it

[1983zsled]

@BigSexxyLee I looked at your video. Nice car! You are right only the 1982 and early 1983 Z-28 came with the red/orange strip along the bottom and the red Z28 emblem on the rockers. What to do with your car? Well you can spend a ton of $ on them upgrading this and that...so I guess it's up to you. Others might disagree I think it is a waste of time spending any $ to make the 305 perform better. I think I would restore it keeping it 100% stock. In the long run, say 20 years it could be worth $

Hello I am doing basiclly the same build you have. I have hyper flat top pistons with four valve relief .030 over . I have the 062 vortec heads and a summit 1103 camshaft. I was wondering what springs and retainers you used on your heads. I've read that the heads can take 475 lift but I've also heard they can not take more then 450 lift with stock springs and retainers. So i was wondering if you give me some tips on what you did on your motor, also what length pushrods? Nice Camaro too!

Sweet Maro man looks mean as hell, is that the original paint?. Thanks for the comment its nice to hear from another camaro bretherin. N I decided to rebuild the old motor n jus keep it stock and reliable. Eventually Im gonna post another video of the new exhaust system I just put on. Its Flowmaster Racing 2.5in. exhaust system that gives it roar.

[1983zsled]
