Finally !
1976 /350 .The maybe will maybe not project . Just picked up my car after finding a new guy that was suppose to work well with older engines . For 30 years I have been trying to get my car to spin the tires without bringing it up to 2500/3000 with my foot on the brake . Had a Rpm Air Gap ( had torker 2 ) installed and tuned . It fit fine under the hood no problems at all . Now the car at idle if you stomp on it smokes the tires also the acceleration will push you back in the seat . It ended up at 34 degrees advanced , at 35 he said it started to ping a little with 91 oct gas . He said with a higher octane gas there is still more in the engine . So I really don't know if its the intake or the guy's tuning that made the improvement . I'm going with 40 pct intake 60 pct tuner . Also for the first time in years I can put the car in park and when I turn the key it shuts right down .

Took it on another 70 mile ride . No change running fine hard part now is keeping it under 60 ( speed limit around here 55 until you get 80 miles from here ).Did it yesterday but it was hard not jumping on it since most of the time I drive in the country , closest town is 15 miles away .

According to that I should be somewhere under 20 hp lose . My fan looks a little less aggressive then the one they have and if I remember right its a flex type . I would like to put mine on a dyno but other then a stand dyno the only chassis dyno I know of is over 200 miles away , and if I were to break something that could be a problem .

Speaking of steering a guy in a direction, Here is your next mod if you want to get back some HP and TQ.

Decided yesterday to push it a little .Haven't really pushed it off the line since i got it back . For a car that i couldn't get the tires to break free at all unless i brake torqued it to around 3000 and then i only got about one tire rotation . I took it up to 1400 and it smoked them for 30 feet + .For being a kind of hodge podge build because i don't know what cam i have and there's been 20 years since i built it and what i have had done now , i am pretty satisfied with the results .Seems like i have a good combo now but i really don't know what it is . Unless something breaks everything i have to do now is cosmetic .

It was tune at a persons house that works at a auto dealer that has a garage set up that does a lot of the local work and also some of the dirt track cars . I went back to where i burn the tires it wasn't 30 feet actually a little over 20 .

So why would you assume there was bad traction . When I compare things its pretty much apples to apples . Its on a couple year old blacktop and before I had the work done it would hardly squeak them . Plus I am the only one that drives the car and as long as it impresses me that's all that counts .

I look at it this way . With the type insurance I have I can only put 3000 miles a year on . So new tires would get somewhere between 10 and 15 years on them by mileage . Last set I had the thread looked like new when I change them but they were over 10 years old .

That would be a good real world performance report and fun at the same time.

Don't have anything close , dyno or 1/4 mile . There is a dyno around 60 miles from here but its not a chassis dyno . Closest is over 200 miles and i don't want to have to pay 1000 bucks to get me and the car back if i broke something . But back in the 90's i did have it on Bristol Race Track for a lap .

Great. Just when I thought that I had settled on sticking with the stock fan setup, you go and post this.
Just what I needed to see.
Even if it's only 20 HP, that is 10% or more of the HP a stock, mid 70's till the end of the C3 run, corvette develops. That is only one advantage of the electric fans.
When I switched to electric fans I could feel the difference in acceleration.
Now back to the subject at hand.

It's funny 5 years ago I couldn't hardly convince anyone that the stock cooling fan is a HP sucking device compared to electric fans. Now there is a video and dyno evidence that people can watch and that makes it more believable somehow. Dyno's had been done before this video proving how much HP a mechanical fan consumes yet it was contested heavily.
