As the title may suggest, I'm planning up for a build on a 305, based mainly towards max low end torque (and mileage to some extent). I'm not concerned with max HP to any degree, the only dyno time this engine will have is while being tuned, and it will be my DD.
My goals are to build a reliable engine that will get an MPG or two more than what I'm getting now (???-23MPG) and that will make better than 320 ft/lbs nice and low (at the engine, not the wheels). The platform is an 89 TPI 305 that will eventually replace the TBI 305 in my 89 TA. Here's what I have in mind so far: Cam selection
- 501A1LUN (Lunati) - 501A2LUN - 501A3LUN - 104204 (Crane Cams)
Exhaust - Hooker Streetforce Headers & Y Pipe (2055) - Hooker Streetforce Cat-back (16820) Engine
Either try to smooth out the stock heads (probably to save some $), or get - World Products SR Torquer Heads (042660).
I'm also toying
with the idea of getting a stroker kit (just to get a new rotating assembly, I'd rather keep the ci at 305), or maybe just a short or long block from Blueprint engines if they can help me out with that.
Thinking about doing some smoothing and mild porting of the plenum (or should I avoid that?). Open to other suggestions though, thanks for your input. Also, what would be the most torque you could make from a 305 with a similar setup? What setup do you use/suggest?
P.S. I am NOT
considering going to a 350, even if "tR
eE-fiDeezS sUK nOO8." I'm just interested in a fun low ci build that'll last for a good long time that doesn't need an oil well or a pit crew to keep running. I have all the small details worked out, I just left them out for space reasons and because this is the stuff I'm not 100% about.
i don't know about those cams, but i thought that stock 305 TPI makes somewhere around 290 ft/lbs, so any improvement over stock will give you the 300 at motor that you want
Whoops, in fact they made 300 in 89. Better up the bar
