'71 Nova LT1 Dyno Tune results

For you guys that saw my previous thread about completing my head and cam swap, I just got back from the dyno tune.

As a recap, I swapped out my stock iron heads for a set of LE2 GM aluminum heads and went in with LE's 218/224 cam. Previous dyno was 247hp/266tq, dyno tune today produced 339hp/326tq. I am extremely pleased especially running shorty headers, 8.5" rear, steel driveshaft and factory converter.

Tuning was done by Alan Futral of Futral Motorsports

I will post the curves tomorrow.

That pretty darn good! Almost a 100hp increase. That's quite a lot of hp man. I wish I had that much!

Thanks for posting those results! Yeah, hell let's see those curves....

Nice numbers for such a small cam, I am going to bring my 383Lt1 to alan for some fine tuning since I swapped to a singleplane intake on my car. Why do you still have sthe stock converter in there? Who did the wiring harness?

The previous owner had done the wiring harness.

I'm pleased with the power, it's all that I wanted for this car.

It sounds like you have a fun ride....Any reason for the shorty headers? Clearance issues?

It had long tubes at one time, but they hung way too low and looked horrible. I may eventually have some built or try a different brand that may fit better. I've got some other plans for the car on my list long before I worry about different headers.
