I have a 82 sport coupe w/ a V6 and a 4spd manual with 157,000 miles on both. I am in search of more power especially on the highway I have to travel a lot so i spend a lot of time on 95 N & I'm tired of getting pick on by everyone & everybody. I have 2 305 longblocks collecting dust in my garage and a t5 also. I would like to create a good daliy driver with what I have to run good mid to high RPM range. what are some suggestions and combos to make this happen as far as : intake, cams, fuel & spark delivery, gearing ect.

Exotic combos are welcome also.

Thanx guys,

Well being a V6 you probably have 3:42 gears in the back. That's a good thing. That's what I have in my car. It was a V6 also. A comp cam XE262H would be a decent cam for that motor. Maybe a XE268H for a bit more. Vortec heads. If you go with the Vortecs, stay with the XE262H cam or plan on doing work to the heads. Then get the Edelbrock Performer RPM Vortec intake and 600 CFM carb. And that 305 would come alive. Get a good distributor with at least a 50,000 volt coil to.

Interesting, barb right on the money w/the gears I crawled under my car and check the rear code thanx

what do you think of a single plane intake and a 294 cam? too much for a 305?

 

If you wanted a single plane, then I'd recommend using TBI.
TBI doesn't need the vacuum signal, like a carb does. The reason that single planes don't work well with carbs, is because the vacuum signal from all 8 cylinders have access to the carb in one spot. With TBI, the fuel is not metered by the engine's pull, and instead by a fuel injector and ECM.
This means that more radical intake systems can be used without the bog, and carb tuning problems.
A stock 305 TBI setup will also provide good fuel economy. My car (which is actually about to become a carbed 305) will get mid 20's (like 25, 26 MPG), on the highway. This is better mileage than my 1997 Escort with a 4 cylinder gets.
In other words, if I want to SAVE GAS on a highway trip, I take the Firebird.

TBI can take a respectable cam (something like the LT1 roller cam), with stock PROM, and increase fuel pressure.
An entire TBI setup, including the wiring harness, TB, injectors, ECM, and sometimes even the computer controlled distributor can be had cheaply. Some guys (like me) will sell all the TBI/ECM related parts off at once, when they're swapping to another induction system, and that will make things easier for guys that want FI.

 

since it's gonna be a daily driver and a 305 i wouldn't go with a single plane. a dual plane would be my intake of choice for a street vehicle. so yes, it would a bit too much for the 305 .

 

Thanx guys for all the good advice.
