[djcoak]

Sounds like crap

[camirocz]

hahahahahahahaha i remember those speedometers man they were sad.

[CrazyForCooCooPuffs]

these cars are capable of getting 20+ mpg but the gear ratio's and the rear end fucks up the entire thing and walla thats how you end up with 10mpg

[69GTOby1]

6x-4 or -8 heads? What's your compression ratio?

[surf403]

You need to fix that nasty ass exhaust leak!!

[nevbot222]

too much awesomeness for the speedometer

[TheIbanezking123]

That got a Q-Jet?

[1981turbota]

@TheIbanezking123 Yep and it runs gooooood!

[DChristianson56]

How do you like this cam? I have vortec heads and I'm stuck, either XE268 or XE262

[beeterolds]

I had the Xe262 cam in my Olds 403 and lemme tell ya that sucker ran damn good with that cam!! nice vid buddy!

[meaningintragedy01]

What kind of gas mileage are you getting with the 400 with that cam and 4 speed? 700r4?

[1981turbota]

It gets around 14 in town and 17 on the highway. Its a borg warner super t10

[meaningintragedy01]

@1981turbota Not bad!

[rockurworld99]

@1981turbota lucky.

[FloNWfan21]

this car cant go more than 80mph?

[1981turbota]

It can, Ive had it to 130. Just the speedometer cuts out at 85.

[kenfo0]

@FloNWfan21 in the late 70's, early 80's, the US govt demanded car manufacturers make speedos that only went up to 85.

[irarawkstarr]

@kenfo0 Except for police cars...

[CLIFFOWNS]

@FloNWfan21 LMAOOOOOO

[StreetLethalRacing]

Are you going to try and adapt the stock turbo setup, but with a bigger turbo of course, onto the 400 Poncho....?

[oldskoolskater233]

Was the 4 speed still an option after 1979? I got an original 4 speed/ 400 79 T/A and that was the only trans available on that motor that year, and it seems like the 80-81 are all automatics. I know yours is newer from the 85 mph speedo, I'm just curious.

[1981turbota]

@oldskoolskater233 It was an option in 81, but only on the 305 chevy. This setup was out of a 77 T/A that I swapped in The car was originally a 301 turbo automatic

[i240robert]

Sounds sooo good. Your torque really pulls mid-range. It's fast and very sweet.

[1981turbota]

@i240robert Thanks! Its a fun driver. Im in the process of making it faster 

[sneish]

nice car - getting one soon, how much of a difference is 301 - 400?

[1981turbota]

I had the turbocharged 301, and the 400 leaves it in the dust easily. Id say easily around 120 or so HP more.

It takes this car ~6 seconds to hit 60 MPH or so depending on how I shift, and it took the 301 around 8.5.

[sneish]

@1981turbota

cheers mate, im doing a lot of research on the car, much appreciated!

[bandit3271980]

its got an 70-79 bezel notice the triangle turn signals thats 70-79 only,80-81 were round do your research

[1981turbota]

because I swapped out my trashed 81 bezel with a good used one. notice the 85MPH speedo and different number font on the gauges and the original turbo hood (originally 301 turbo) its an 81.

[yuhmother]

@1981turbota you know your stuff, cause I own a 81 and i was like that's not a 81 TA dash (^_^) lol
