Default Another Fav Mag article

Hot Rod magazine Sept 2009 "Four-Way Bumpstick Blowout"

Took a 6.0 LS added LS3 heads. Did both carb and fuel injection tests using the 4 most popular LS cams. Remember this is over a year and a half ago when you consider the mag leed times.

Great reading.

Good re-read lol. I think the carb could have matched or exceeded the efi in the midrange with closer attention to tuning the air bleeds

I would suspect that the longer runners of the EFI intake is where the extra torque is coming from. I would be surprised if the short runner single plane intake can match that on a big headed motor.

That article was what convinced me to go carb and what cam I wanted. I used the 224/230 dur. and 581/591 lift. I only have the stock cathedral port heads with new Stainless Manley valves. If I would have had the rectangle port heads with the bigger valves I would probably gone with more cam.

Thumbs up New Dog Old Trick!

http://superchevy.com/technical/engi...mpp/index.html
this article is the original ls carb swap test back in the days .article was in pphr magazine. it was the article that got me to start looking into carbed ls. the little msd/edelbrock box works well for its basic purpose to fire the coils. theres even dyno results with cam and springs swap.

on a side note: when this was being tested the FAST 90 was still in prototype stages and was still being designed on.
it was an article in the same mag.
i still have that mag to this day, New Dog Old Trick is one of my fave LS articles.

that little edelbrock box test definitely began the carb ls movement. i am very fond of using it. since it was the first product to fire an ls with a carb

Do they expect us to look up the specs on all those? Why didn't they post them?
